Epic Cash AMA Recap with CryptoDiffer Community

CryptoDiffer team Hello, everyone! We are glad to meet here: Max Freeman (@maxfreeman4), Project Lead at Epic Cash Yoga Dude (@Yogadude), PR&Marketing at Epic Cash Xenolink (@Xenolink), Advisor at Epic Cash
Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here!
Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here!
Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us!
CryptoDiffer team Let`s start from the first introduction question: Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash?
Yoga Dude PR&Marketing at Epic Cash
Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing.
I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially.
Xenolink Advisor at Epic Cash
Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers!
Max Freeman Project Lead at Epic Cash
I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level.
CryptoDiffer team
Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:)
Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one?
Max Freeman Project Lead at Epic Cash
I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble
We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly.
There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos
that explain why we believe we have created something truly special here.
Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange.
Yoga Dude PR&Marketing at Epic Cash
Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility.
Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved.
Xenolink Advisor at Epic Cash
To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry.
To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone.
CryptoDiffer team
Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months?
Yoga Dude PR&Marketing at Epic Cash
Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content.
We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money.
You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages
Max Freeman Project Lead at Epic Cash
Our future development roadmap will be published soon and includes 4 tracks:
Usability
Mining
Core Protocol
Ecosystem Development
Core Protocol
Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020
Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020
Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a
Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a
Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a
Usability
GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020
Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020
Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a
Mining
RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a
The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin.
Ecosystem Development
Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a
Xenolink Advisor at Epic Cash
From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide.
CryptoDiffer team
Great, thank you for your answers, we now can move to community questions part!
Cryptodiffer Community
You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC?
Max Freeman Project Lead at Epic Cash
The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part.
Cryptodiffer Community
To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from?
Xenolink Advisor at Epic Cash
Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project.
Cryptodiffer Community
Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you!
Yoga Dude PR&Marketing at Epic Cash
First, I must admit that I am still a huge fan and HODLer of Monero. That said:
✅ our blockchain is MUCH lighter than Monero’s
✅ our transaction processing speed is much faster
✅ our address-less blockchain is more private
✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU

  1. the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
  2. On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
  1. This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
  2. The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.

$EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future?
Who is Epic Biggest competitors?
And what’s makes epic better than competitors?
Xenolink Advisor at Epic Cash
We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity.
Cryptodiffer Community
What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships?
Yoga Dude PR&Marketing at Epic Cash
Since we are a community project, we have many developers, in addition to the core team.
Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks.
We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked.
Cryptodiffer Community
EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges?
Xenolink Advisor at Epic Cash
In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well.

What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Max Freeman Project Lead at Epic Cash
Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic.
With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash.
As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability
Cryptodiffer Community
Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ?
Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors?
Max Freeman Project Lead at Epic Cash
RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware.
Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses.
Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware.
The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved.
Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem?
Xenolink Advisor at Epic Cash
Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic.
Cryptodiffer Community
I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto?
What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ?
Yoga Dude Pr&Marketing at Epic Cash
Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential.
The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers.
The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique
Cryptodiffer Community
Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI?
Yoga Dude PR&Marketing at Epic Cash
We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on.
Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way.

If you could choose one celebrity to promote Epic-cash, who that would be?
Max Freeman Project Lead at Epic Cash
I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences.
I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today.
Epic Cash will have its OWN Celebrities

How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it?
Xenolink Advisor at Epic Cash
Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin.
Cryptodiffer Community
what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ?
Max Freeman Project Lead at Epic Cash
There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make.
Cryptodiffer Community
Q1 : What are your major goals to archive in the next 3–4 years?
Q2 : What are your plans to expand and gain more adoption?
Yoga Dude Pr&Marketing at Epic Cash
Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁
We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting.
Cryptodiffer Community
It seems to me that EpicCash will have its first Halving, right? Why a halving so soon?
Is a mobile version feasible?
Max Freeman Project Lead at Epic Cash
Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140.
Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining.
Cryptodiffer Community
What markets will you add after that?
Yoga Dude PR&Marketing at Epic Cash
Well, we are aiming to have ALL markets
Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry)
We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages.
Epic Cash is More than Money and its for Everyone.
Cryptodiffer Community
Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins?
Max Freeman Project Lead at Epic Cash
With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can.
Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises.
Cryptodiffer Community
What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment?
Xenolink Advisor at Epic Cash
Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash.

  1. You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
  2. How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash
Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well.

Do EPICs in 2020 focus more on research and coding, or on sales and implementation?
Yoga Dude PR&Marketing at Epic Cash
We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy.
In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC.
Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters.
Everyone with skin in the game gets the benefit of advancing the cause.
Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content —
https://www.youtube.com/watch?v=XtAVEqKGgqY
a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this

I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex?
Let’s talk about the economic model, can EpicCash comply with the concept of value reserve?
Max Freeman Project Lead at Epic Cash
In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader.
We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166

Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project.

Building Ergo: Lite full nodes

Ergo allows any user to run a full node with low resources – meaning you can help maintain the network with a device as simple as a Raspberry Pi.
In a previous post, we looked at Ergo’s SPV mode, which allows for secure, efficient mobile clients. This enables users to make transactions using almost any device.
At the other end of the scale, you might want to run a full node. If you’re a miner, this will require that you download the full blockchain, because you’ll need the whole UTXO (unspent outputs) set to mine new blocks. But you can still run a full node without that UTXO set – vastly reducing the specification and expense of the hardware needed.
Ergo blocks
In Ergo, just like Bitcoin, Ethereum and other blockchains, blocks are broken into sections. In Bitcoin, there’s simply a block header and the transactions themselves. But in Ergo, we have some extra sections that enable new functionality:
The ‘extension’ section contains certain mandatory fields (including links for NiPoPoW, once per 1,024 block epoch) and parameters for miner voting, such as current block size. It can also contain arbitrary fields.
What this means in practice is that different types of node and client can download only those sections of the blocks they need – reducing the demands for storage, bandwidth and CPU cycles.
Lite full nodes
While miners need to download everything, lite full nodes only need the transactions and proofs. This means they have a cryptographic guarantee of transactions, without holding the full UTXO set itself.
Lite full nodes check the proofs generated by full nodes (including miners) who do hold the full blockchain, providing a guarantee of ledger validity. In Ethereum, these nodes are called Stateless Clients.
For Ergo, it means you can run a full node and maintain the network with a device as simple as a Raspberry Pi with 512 MB RAM. This provides the ideal balance between ensuring the security of the network and placing an unnecessary burden on users who wish to do so – improving decentralisation and democratising participation in the Ergo network and community.

I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!

Requirements:
1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does.
**Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc*
So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though.
After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there.
Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly).
I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01
Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!!
-----How To Do This Yourself:
Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money.
Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses.
Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!)
Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!!

Governments CAN kill Bitcoin- they just don't care (for now)

I understand that my opinion is probably an unpopular one, so I expect a ton of downvotes.
Let's imagine a perfect scenario- everyone knows for Bitcoin, volume is high, people are spending it and/ or stacking sats. Now, this is not a good thing for govs, reasons were mentioned thousands of times on the internet so I will not bother about mentioning all of that again. How to kill Bitcoin, you may ask? Declare it illegal, start the propaganda machine, prosecute people who are mining or using it, shut down mining farms under the accusation of supporting the system that is used by criminals- add a bit of human trafficking, drug dealing and money laundering to the headlines to make it look justifiable in the eyes of average Joe. After all of that, hashing power will probably go to 20% of what is now. Next step, seize the ASICS and conduct a 51% attack. Congrats, no more BTC. You may say that your rights are hurt, but CCP (Communist Party of China) doesn't give a fuck.
There is a cryptocurrency that could survive a "mass extinction" of that kind. It's called Idena and it's truly unstoppable. It's using a novel protocol called "Proof of Person". In order to mine it, you must prove (validate) that you are actually a human being, all without 3rd party or personally identifiable documents (aka KYC). How to prove that you're actually a human being? Currently, validation days happen a few times a month, and validations start at the same time all over the globe- New York is at 9:30AM, Berlin is at 3:30PM and Sydney is at 11:30PM. Validations involve solving a user-made flips- they are captchas that are impossible to solve by machines- because they involve abstract thinking and emotions, which only humans have. Incentive to make flips is simple- to validate on next validation day you must make 3 flips which will be randomly distributed to other users on the next validation day. Idena introduces sybil resistance by limiting the time of validations, you can validate yourself on one node, it's almost impossible for one person to have two nodes. All mining rewards are split equally to every miner, so there is no concentration of hashing power, mining farms are impossible and stopping/ censoring is impossible because Idena can work on any 64bit OS- Windows, Linux, MacOS and even Raspberry Pi- Computing power is irrelevant and it will be irrelevant forever! To stop Idena, governments must ban computers, from all people who are running this most decentralized and democratic currency on the globe! Sounds like an impossible task to me.

read.cash censorship! 🤬

Well, now that I've got your attention, I want to talk with you about something serious.
Something that we've been expecting from day one opening read.cash happened. We've had to hide an article from the main page and the topic pages.
The article is (in our subjective opinion) an insulting piece of content to some people. And I, as the one who removed it, wanted to show it to you, including our whole discussion with its author.
We at read.cash want to be clear from day one that "We strive to build a place with great content to read and watch, where authors can be compensated by their readers, not the place with never-ending fights or spam" This is written in the "About" page from day one.
Unfortunately, it also means having to moderate discussions, something that some people refer to as "censorship".
We don't hide this fact. We are ok with discussions.
Want to discuss why Bitcoin SV made some bad choices and how it would never amount to anything - avoid name-calling and trash-talking and be our guest - aboslutely OK.
Do you want to criticize Bitcoin Cash because you believe that 32 MB blocks are too big and Raspberry Pis should be the miners? Be polite and you're welcome to explain yourself.
Do you want to call people "cuckolds", "bcashers" or "coretards"? Please leave, the content is going to be removed.
Anyway, we're not forcing people to love read.cash, it is, what it is. We want to make sure that authors that write great content - get compensated well by their fans.
Do you want endless flame wars? There's Twitter, and other sites that are more appropriate.
You are all grown ups and free to make your own mind about whether read.cash is suitable for you or not, we're making our policy clear.
Feel free to read this post in full and we encourage @kos (don't know the Reddit username) to join the discussion. He(she?) feels it's "haha funny article m'dude", we feel it crosses the like of being "hate-filled" (subjective term, but we stand by it).
Here's the article with discussion in full:

Guide To Mine Bitcoin With Raspberry Pi?

Hi guys I'm bored, want something fun to do with a spare 2B, anyone got an easy to follow guide to do this? I know I won't make any bitcoins, but its something Ive wanted to do for a few years and never had the time. Thank you very much for the help!
submitted by geregegregw to raspberry_pi [link] [comments]

When Craig starts mining on BTC using his original non-Segwit protocol and grabbing everyone's Segwit coins it will not be a 51% attack. It will legally be a 51% defence.

Segwit right now on BTC is a 51% attack. It is a 51% attack that the majority have accepted, thus it is termed "a soft fork" but on the pure technical level they are exactly the same thing, except they'd term it an attack if it was a soft-fork without social consensus. Anything over 51% has technical consensus, the real consensus that matters in Bitcoin. All node software would follow this chain as it would not be breaking the hard rules.
A miner with 51% of hashpower trying to for instance pay himself 100,000BTC as a block reward would not be within consensus, he'd just be hard-forking, and would be a 100% miner - but on his own chain which would be worthless and of no concern. A hard-fork being accepted implies a loosening of the rules (all nodes would need to change their software to allow 100,000BTC block rewards for this attack to work).
Now a soft fork is a tightening of the consensus rules, what once were "Anyone Can Spend" transactions which quite literally meant was money to be picked up by any miner and spent, are now soft-forked into being "hey you can't spend these - they're Segwit" and providing 51% of the miners are still going along with the soft-fork any attempt to spend them will not be allowed to be propagated and built on as a valid block. No node software needs to be changed to follow these rules, which is why old Bitcoin software before Segwit can still sync up to the latest block however due to the kludgey way Segwit works it sees them as "Anyone Can Spend" transactions and doesn't really understand them or the segmented signatures. So it's pretty useless to use and for a miner could only mine a empty block or a block with non-Segwit transactions, and if it tried to spend a segwit address other miners understanding segwit would reject its block.
But if a 51% majority starts to reject this soft-fork, then all Segwit addresses can be emptied out with the money going to the miner and there is nothing that the 49% of miners or the 100% of soyboys running non-mining Raspberry Pi nodes can do about it other than shitstorm on Twitter, FUD themselves to death and (try to) dump their BTC.
Make no mistakes - it will totally collapse the coin and its value will rapidly become 0 as nobody will be able to move it. Exchanges will be the first to freeze, and a crypto without any exchanges and with most wallets being emptied by miners will trash the HODLings in non-Segwit addresses too. Miners will start mining on BSV and/or BAB and with the hashpower (security) dropping dramatically and approaching "mom's basement" levels of hashpower BTC will never ever be able to recover. Then fun things such as massive re-orgs and continuous empty blocks with political messages inside them will take place just for LOLz.
All the cryptoworlds anger will be pointed at Craig (I think like Honeybadger he won't give a shit as he's used to this) but legally not only is he only following protocol, he'll also be following the protocol that he copyrighted and everybody else will be the rogue actors, the ones culpable for this massive loss, as Craig takes down the 51% attack (Segwit) that they've been running a few years now.
Craig has been nice and put out numerous warnings - now it's time to just wait as he reclaims his protocol.

How Did I Discover Cryptocurrency and Why I Choose BitcoinCash

How Did I Discover Cryptocurrency and Why I Choose BitcoinCash.
One of the first questions always asked in the Crypto sphere is how did you learn about Bitcoin? Then followed up by which coin or coins do you hold?
The answer to this first question is not as easy to answer as you would think. Right before the split between Bitcoin and BitcoinCash I met someone very involved in the community we were discussing how I became a libertarian which naturally lead us to a discussion about economic freedom, Ross Ulbricht and then Bitcoin. The following day I ran home and researched Silk Road and Ross Ulbricht. Five minutes later, I had signed the petition. My interest was piqued, I started to do my own research in regards to Bitcoin. I bought several books but all that did was confuse me more. I started watching YouTube videos and remember thinking to myself “who are these people” and “are they even speaking English” but I kept researching determined to learn about economic freedom, I just couldn’t grasp how someone could gain economic freedom with online money.
Fast forward to the Bitcoin/BitcoinCash fork, I knew this was a big deal but I didn’t know what was going to happen. So I called my friend and set up another time to meet, well this time I was prepared I had my notes laid out from the books I had read and I was pretty proud of myself after all Bitcoin is not easy to understand with words like nodes, Raspberry Pi's (what does pie have to do with economic freedom), miners, QR's, checkpoints, lightning (still waiting) and why only 21 million and do I have to buy a full coin? I mean this list goes on (after all I am much older than the usual crypto enthusiast) little did I know I had already entered the rabbit hole and from the look I received from my friend he knew it. So after 2 days that was it, I needed to get my hands on Bitcoin.
As soon as I got home I joined Coinbase and I saw a few coins listed and thought Bitcoin is really expensive and I can get 4 times the amount with this coin called Litecoin so I put in a buy order for that, Etherum and BitcoinCash. I had never been a huge fan of Social Media but at this time I decided I needed to join Twitter to see what others were experiencing and oh God what a jolt to the senses that was. Everyone tweeting why this and that coin is bad and this person is bad and that person is good, Crypto Twitter can be a shit show especially in the beginning and being new to both Twitter and Crypto my brain was in overload. I followed my friend on Twitter and just started to pay attention to him and basically began stalking his feed and Youtube channel but I never really engaged (I truly felt like a stalker). But I was learning my way around and who did what in their relative fields.
As everyone knows Coinbase can be very frustrating because it seems like forever before you have access to your coins and the whole time I’m thinking what have I done? So a month went by and I finally received an email saying my funds are now available in Coinbase I opened up that app and to my surprise, my money had just quadrupled. I had learned while investing once you make back your initial investment sell that portion and that is exactly what I did! But the damage had been done I was hooked and immediately took that initial investment and bought every altcoin I could get my hands on via Binance, which can seriously do some damage to your wallet.
I still really did not know what to do with Cryptocurrency, there were all these wallets, but why were they needed if all it did was sit there like digital gold. So I started to engage with people on Twitter to discover what others were doing, I didn’t have any followers so outside of a few likes here and there I would never really get any feedback. I asked my friend about this and he started to respond to me and soon after that, others started to respond to me, then I was included in threads and I had my first Crypto Twitter follower, he was no joke and little did I know at that time how much of an influence this person would have in my Twitter and Crypto life. But Crypto Twitter will have to be its own story.
As I started to learn how to navigate my way through Crypto Twitter and began to understand the correct questions to ask I began to get the answers I needed. These questions amounted to where/who accepts crypto and why is this coin better than that coin? The people that came forward were the BitcoinCash community, I couldn’t understand why was it only the BitcoinCash people that would respond to me, after all, there are so many coins out there? But these were the people that had a passion for what they were doing and believed in that passion, from the CEO to the developers down to the end user. It was like a breath of fresh air to find people passionate about rewarding hard work and not caring about who you are and which country you are from along with giving back to communities that are far less fortunate by no fault of their own they just don’t have access to resources that are available to Western Nations, Europe, and Asia. I discovered the philanthropic work was incredible and still to this day I still am overwhelmed by how much the BitcoinCash community does and feel very fortunate to be a part of it.
Downloading wallet after wallet, I discovered some were easy some were difficult and well some were just ridiculous. I started to tag random developers on Twitter and honestly was surprised when they responded to me and offered their help after all these are really busy people why would they take the time to help one person. The reason is simple they want Cryptocurrency to be a success and they understand how difficult it is, especially for an older person who just got her first smartphone 2 years earlier. After learning about the importance of 12-word seed phrases how a QR code works and legacy addresses I now felt comfortable enough to begin introducing people to cryptocurrency and more importantly BitcoinCash. Little did I know how difficult this would be, I mean who doesn’t want money even if it’s free.
After months of interaction on Twitter and other platforms, I decided I needed to do something besides just talking about Crypto I needed to shout it from the rooftops. I desperately wanted to find others around me that I could share my experiences with so I created a Meetup in my area and began talking about it at work with my friends and family I just started telling everyone I ran into have you heard about BitcoinCash? “No” here let me show you” inevitably I started to hear oh that’s for drug dealers or it’s a scam. So now I thought how do I get past this obstacle that CNN and Fox News has put in front of me? I became more determined than ever to beat them at their own game. I had another hurdle to jump, so my path now came to what is an everyday product I can buy with Bitcoincash? Well, there are tons you just have to find them, and since my area of the country is about 10 years behind the rest of the country this was very difficult. But one thing I do a lot is travel and I was about to buy a plane ticket so I found CheapAir.com which accepts BitcoinCash, so I used that and discovered how easy it is, I can literally lay in bed find a flight and/or a hotel and right there without turning on the lights or getting up for my credit card number. What about overcoming only drug dealers use it (which my stepmom throws in my face almost every day) so for Christmas I purchased her some beauty products with BitcoinCash. I am constantly scouring the internet looking for more ways to spend Crypto instead of government-funded cash.
My meetups started out with 2 people 1 of which was my dad to 12 strong and growing (which does not include my dad). That may not seem like many but those 12 people have become strong and confident users of Cryptocurrency and one of them even accepts BitcoinCash for his business.
My story does not end here, and with every day there is a change with some great, some good and some not so good stories. Keep your eyes out for updates to my never ending and exciting Crypto life.

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.

Winner:

icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)

Links:

Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)

Questions

What can I do with an FPGA? / How many LUTs do I need?

Lightning!

Lightning Network
Today I am going to talk about the “Lightning Network” which is a proposed solution to the issue of scaling Bitcoin faces. Lightning Network (I will use the acronym “LN” to refer to the Lightning network from this point forth) LN has its fair share of criticism in the crypto space. Some claim its brilliant, while others claim it is the antithesis of what Bitcoin was supposed to be. I am going to try my best to touch on the reasoning both crowds use to come to these conclusions. First things first, lets discuss how the whole thing got started.
The LN was first proposed in 2015 by Thaddeus Dryja and Joseph Poon in a white paper they wrote (White paper for LN can be viewed at the following linkhttps://www.weusecoins.com/assets/pdf/library/Lightning%20Network%20Whitepaper.pdf ) They decided that Bitcoin has a scalability issue and were looking for the best way to solve that issue without ultimately sacrificing the fundamentals that make BTC such a great currency. They decided that building a 2nd layer on top of Bitcoin was the best solution (rather than another useless hard fork to add to the 103 or so other Bitcoin forks out there) Many claim that coins like Bitcoin SV and Bitcoin Cash are the solution to scaling issues, but they are forks and centralized when compared to Bitcoin which sacrifices decentralization for scalability. Lightning is different than a fork as it is basically a payment channel that connects 2 or more parties directly. This makes payments almost instant, which is something people using Bitcoin core have desired since its creation. How does it work? Lets discuss that!
How does the Lightning Network work?
Okay so you have been hearing your friend Phil go on and on about how great the LN is, but why is he so excited? Lets figure it out! The LN is a payment channel that is set up between 2 or more parties. They start by creating the payment channel which is a multisig wallet (a multisig wallet is a BTC wallet that cannot be accessed by just one party as it takes “multiple signatures” to access the funds. Now that Phil and I have set up the payment channel we can now transact with each other as much as we like with no transaction fees (until we close the channel). The payment channel gets updated every time a payment is made. So if Phil and I have 2 Bitcoin on the channel, lets say I have 1 BTC and Phil has 1 Bitcoin in the multisig wallet me and him created for the Lightning channel. I could send Phil ½ of a BTC and the ledger would show that Phil now has 1.5 Bitcoin while I only hold .5 Bitcoin. This transaction occurred off the Bitcoin blockchain so it avoided the hefty transaction fees that accompany Bitcoin core transactions at times. The channel can be left open and the ledger will update every time me and Phil transact with each other (until we decide to close the channel) This layer makes micro transactions more feasible as people are not paying a 3 $ transaction fee for a 1$ transaction.
People that would like to use the LN can get a node (Casanode, Raspberry Pi 3 etc.) which will also act as a BTC core node along with a lightning node. This is a popular way to be a part of Lightning payments. It is not the only way though. There are wallets that can be used to access the LN without having to own a casanode or raspberry pi. You can still use the LN without owning a casanode by downloading an app like “Blue Wallet” which will allow you to access LN without necessarily owning a node. Apps like this make LN more available to the general public that may not quite grasp the reason people own casanodes. Either way removing barriers that could potentially hinder people from using LN is a big part of wide spread adoption. Lightning is still in its infancy really so more and more apps should pop up similar to Blue Wallet in the near future. (This is not an endorsement of Blue Wallet, I simply used it as an example) If you would like to order a casanode it can easily be found with a simple google search. I personally know a few people that paid for the node and most of them did it just to help the LN network grow and to actually be able to use it! They typically run for around $300 USD. (I see the price going down in the future as LN becomes more used and the casanodes become more in demand)
Now just because you aren’t connected to someone directly through a payment channel you can still send payments to someone in many cases. So, Lets say Phil and I want to transact with each other but we don’t have a channel connecting us. We could utilize a 3rd party to connect the payment channels. For example, I am trying to send Phil 1 BTC, but we don’t have a channel set up, but we want to transact with each other. The node will find the fastest path it can to Phil so I do not necessarily need to create a channel with him. We could use anyone to bridge the gap and transact with each other in this way. This is referred to as a “Hop”. Some people may worry that the link between me and Phil may act maliciously and attempt to take the payment, but that’s the beauty of LN. It can’t be taken in this way. So I send Phil .1 BTC. A 3rd party would first receive the .1 BTC and would send it to Phil automatically. The 3rd party cannot stop the transaction in the middle if he were to try and steal the funds. LN doesn’t allow that.
LN offers almost instant payments with Bitcoin (and soon many altcoins will also utilize LN) with minimal fees. Some think the LN is absolutely a terrible idea. They believe transaction fees will be severely diminished in the wake of LN due to the fact payments made on LN do not post to the BTC chain until the channel has been closed charging a one-time fee for multiple transactions. I would say that with LN we will see a surge of new adoption that will increase the use of BTC and in the long run should increase the amount of transaction fees collected by miners for the work the perform. People like to claim LN is centralized and the antithesis of what Satoshi was thinking when he created BTC. I have to say I disagree. LN is a layer on top of BTC. It doesn’t effect the fundamentals of BTC core and that is important to me and many others. Bitcoin is a work of art because of decentralization. LN doesn’t hinder this. It is simply an option for people that want BTC payments faster to have a means to do so. In the future people will most likely do plenty of transactions on LN (I think most dealings will be done via LN) But the big transfers will still likely be done on BTC core itself. Bitcoin is a work in progress and LN is a step towards adoption.
Right now, LN is very new and still untested in many ways. It is an experiment in my eyes that is likely to succeed. Even if LN went belly up tomorrow BTC will still be here. I have a lot of faith in LN and I think it will be a huge part of mass adoption in the future. Nobody can see the future… But we can speculate! I enjoyed writing this and I hope you learned something. I sure did.

Spock & CoinEx AMA Recap

Spock & CoinEx AMA Recap

https://preview.redd.it/1lagrcjnc9o31.png?width=1074&format=png&auto=webp&s=3136db9ca685dc17477d307df722e5b73ba80030
Spock Network is a decentralized storage platform. In the early stage, Spock Network mainly stores Proof of Capacity (POC) consensus data to effectively utilize the most suitable decentralization technology to encourage miners providing hard disk space. Recently, Spock has been growing rapidly and getting listed on four famous exchanges including CoinEx. On Sept. 19, CoinEx will launch Accelerator for Spock, allowing users to subscribe SPOK with 0.0075 USD. Besides, in order to help our users to dig more about Spock, we have invited the open source code contributor of Spock, Titian Xie, to throw an AMA among our community. Below is the recap of the AMA and enjoy your reading!

Q1: How will Spock solve the existing problems in blockchain?
A: Spock is a decentralized storage application network. Judged from the current development of blockchain technology, PoC is the only choice for a decentralized incentive mechanism in a distributed network composed of a large amount of hard disk space and bandwidth. On one hand, this solves the problem of excessive power consumption in the current mining industry, and on the other hand, it solves the problem of fair competition among a large number of existing hard-disk mining machines. At the same time, on that basis, Spock also supports Solidity smart contracts, which makes the entire ecosystem more prosperous.
Q2: Could you please say something about the team?
A: The core members of our team are all early users on Bitcointalk forum and developers of Burst. They are very familiar with the technology development trend and the details of the bottom of the blockchain technology. Even I with such a R&D background could only throw myself down at their feet in admiration. Their ideals are also very pure, that is, to make Spock a community coin like Bitcoin and Litecoin.
Q3: Community building has just started. What will you do to build the social media that remain active and continuously focus on Spock?
A: Spock is a decentralized application platform. The community also relies on spontaneous word of mouth. Since Spock was put on the test net and later on the main net, many miners and holders have spontaneously joined in to become owners, and maintained and promoted the community. The upcoming Solidity smart contracts can be carried out by polling among the holders, and members of the community will vote through the smart contract to determine the project function expansion and community governance.
Q4: Spock is a decentralized storage application platform, so what advantages does it have compared with the traditional centralized storage platform?
A: Traditional centralized storage platforms generally adopt cloud storage. Most of the data is stored on a few cloud platforms, which leads to serious centralization problems arising from data accumulation. There are also problems including higher cost, slower transfer rate, and poorer data security. The decentralized storage application platform encrypts and distributes data through a distributed network, meaning that no party, other than the data holder, could get access to the data, thus ensuring security. And one of the key issues is that the open decentralized platform can do better in protecting private data. As with the case of the assets of the digital assets of Huobi, the private key represents the ownership of the assets, and, on the decentralized storage platform, it can represent the disposition and access rights of the data.
Q5: Spock adopts the consensus mechanism of PoC. What advantages and disadvantages does PoC have compared with PoW and PoS?
A: In terms of resource usage, PoC is just between PoW and PoS, unlike PoW which consumes a lot of power, or PoS that almost costs nothing. Besides, since the core mechanism of PoC is similar to storing the “hashrate” of PoW on the hard disk, it also makes it possible for the mining equipment to mine in different projects at the same time, provided that several different projects use the same data structure.
Q6: We noticed that Spock also introduced the PoS mechanism on the basis of PoC. What is the consideration?
A: With the POS mechanism added in SPOCK, when a miner package a block, if its address balance satisfies the condition, he or she get get all the proceeds; otherwise, the proceeds will be reduced, and those that fail to meet the conditions will be destroyed. So in my opinion, developers introduce POS mechanisms to create a more equitable and sustainable ecosystem.
Q7: What will the team do to attract more developers to join the Spock ecosystem?
A: Spock is the first public link that supports the Solidity Smart Contract and has been put on the main net. It allows developers to port the DApp on the Ethernet to the network at a very low cost, while developers can design the mining and pledge mechanisms for the tokens of PoC distributed on this network.
Q8: What is the form of Spock mining? What are the conditions for miner application?
A: In SPOCK, mining is carried out through the storage device. First, you write the result of the hash calculation to the device, and reduce the huge hash calculation required in PoW algorithm by retrieving the data in the hard disk. Only a small amount of hash calculation will be required in execution stage. You can mine as long as you have storage equipment and meet the hashrate conditions. Ordinary miners just need an ordinary computer with a hard disk and access to the internet, then they need to go through hard drive mapping, download the wallet, install nodes and so on before mining.
Q9: I am a Windows phone user. How do I download a SPOK wallet?
A: At present there is only the Android version. Versions of other platforms are subject to the official arrangement.
Q10: Miners don’t know how much hashrate they have or how much they could pledge.
A: Check http://www.spockpool.com. There is a calculator to check the amount of pledges required for the time being.
Q11: Does the mining cost anything or a certain amount of SPOK tokens?
A: Now we have a market for cooperative mining. Miners can borrow tokens from owners for mortgage.
Q12: Is there a detailed tutorial for mining?
A:https://www.spockchain.org/download/SpockChain%20Mining%20Tutorial%20V1.3.2.pdf
Q13: What are the advantages compared with Lambda or such? The larger the hard disk, the higher the hashrate?
A: My suggestion is to experience the mining process on both official sites so you may understand the differences between them.
Q14: Can we use the Raspberry Pi to mine at home?
A: Yes, theoretically. Yet the weak computing power of Raspberry Pi itself may affect efficiency in hard drive mapping.

This is the end of the sharing. See you next time!

How Did I Discover Cryptocurrency and Why I Choose BitcoinCash

One of the first questions always asked in the Crypto sphere is how did you learn about Bitcoin? Then followed up by which coin or coins do you hold?
The answer to this first question is not as easy to answer as you would think. Right before the split between Bitcoin and BitcoinCash I met someone very involved in the community we were discussing how I became a libertarian which naturally lead us to a discussion about economic freedom, Ross Ulbricht and then Bitcoin. The following day I ran home and researched Silk Road and Ross Ulbricht. Five minutes later, I had signed the petition. My interest was piqued, I started to do my own research in regards to Bitcoin. I bought several books but all that did was confuse me more. I started watching YouTube videos and remember thinking to myself “who are these people” and “are they even speaking English” but I kept researching determined to learn about economic freedom, I just couldn’t grasp how someone could gain economic freedom with online money.
Fast forward to the Bitcoin/BitcoinCash fork, I knew this was a big deal but I didn’t know what was going to happen. So I called my friend and set up another time to meet, well this time I was prepared I had my notes laid out from the books I had read and I was pretty proud of myself after all Bitcoin is not easy to understand with words like nodes, Raspberry Pi's (what does pie have to do with economic freedom), miners, QR's, checkpoints, lightning (still waiting) and why only 21 million and do I have to buy a full coin? I mean this list goes on (after all I am much older than the usual crypto enthusiast) little did I know I had already entered the rabbit hole and from the look I received from my friend he knew it. So after 2 days that was it, I needed to get my hands on Bitcoin.
As soon as I got home I joined Coinbase and I saw a few coins listed and thought Bitcoin is really expensive and I can get 4 times the amount with this coin called Litecoin so I put in a buy order for that, Etherum and BitcoinCash. I had never been a huge fan of Social Media but at this time I decided I needed to join Twitter to see what others were experiencing and oh God what a jolt to the senses that was. Everyone tweeting why this and that coin is bad and this person is bad and that person is good, Crypto Twitter can be a shit show especially in the beginning and being new to both Twitter and Crypto my brain was in overload. I followed my friend on Twitter and just started to pay attention to him and basically began stalking his feed and Youtube channel but I never really engaged (I truly felt like a stalker). But I was learning my way around and who did what in their relative fields.
As everyone knows Coinbase can be very frustrating because it seems like forever before you have access to your coins and the whole time I’m thinking what have I done? So a month went by and I finally received an email saying my funds are now available in Coinbase I opened up that app and to my surprise, my money had just quadrupled. I had learned while investing once you make back your initial investment sell that portion and that is exactly what I did! But the damage had been done I was hooked and immediately took that initial investment and bought every altcoin I could get my hands on via Binance, which can seriously do some damage to your wallet.
I still really did not know what to do with Cryptocurrency, there were all these wallets, but why were they needed if all it did was sit there like digital gold. So I started to engage with people on Twitter to discover what others were doing, I didn’t have any followers so outside of a few likes here and there I would never really get any feedback. I asked my friend about this and he started to respond to me and soon after that, others started to respond to me, then I was included in threads and I had my first Crypto Twitter follower, he was no joke and little did I know at that time how much of an influence this person would have in my Twitter and Crypto life. But Crypto Twitter will have to be its own story.
As I started to learn how to navigate my way through Crypto Twitter and began to understand the correct questions to ask I began to get the answers I needed. These questions amounted to where/who accepts crypto and why is this coin better than that coin? The people that came forward were the BitcoinCash community, I couldn’t understand why was it only the BitcoinCash people that would respond to me, after all, there are so many coins out there? But these were the people that had a passion for what they were doing and believed in that passion, from the CEO to the developers down to the end user. It was like a breath of fresh air to find people passionate about rewarding hard work and not caring about who you are and which country you are from along with giving back to communities that are far less fortunate by no fault of their own they just don’t have access to resources that are available to Western Nations, Europe, and Asia. I discovered the philanthropic work was incredible and still to this day I still am overwhelmed by how much the BitcoinCash community does and feel very fortunate to be a part of it.
Downloading wallet after wallet, I discovered some were easy some were difficult and well some were just ridiculous. I started to tag random developers on Twitter and honestly was surprised when they responded to me and offered their help after all these are really busy people why would they take the time to help one person. The reason is simple they want Cryptocurrency to be a success and they understand how difficult it is, especially for an older person who just got her first smartphone 2 years earlier. After learning about the importance of 12-word seed phrases how a QR code works and legacy addresses I now felt comfortable enough to begin introducing people to cryptocurrency and more importantly BitcoinCash. Little did I know how difficult this would be, I mean who doesn’t want money even if it’s free.
After months of interaction on Twitter and other platforms, I decided I needed to do something besides just talking about Crypto I needed to shout it from the rooftops. I desperately wanted to find others around me that I could share my experiences with so I created a Meetup in my area and began talking about it at work with my friends and family I just started telling everyone I ran into have you heard about BitcoinCash? “No” here let me show you” inevitably I started to hear oh that’s for drug dealers or it’s a scam. So now I thought how do I get past this obstacle that CNN and Fox News has put in front of me? I became more determined than ever to beat them at their own game. I had another hurdle to jump, so my path now came to what is an everyday product I can buy with Bitcoincash? Well, there are tons you just have to find them, and since my area of the country is about 10 years behind the rest of the country this was very difficult. But one thing I do a lot is travel and I was about to buy a plane ticket so I found CheapAir.com which accepts BitcoinCash, so I used that and discovered how easy it is, I can literally lay in bed find a flight and/or a hotel and right there without turning on the lights or getting up for my credit card number. What about overcoming only drug dealers use it (which my stepmom throws in my face almost every day) so for Christmas I purchased her some beauty products with BitcoinCash. I am constantly scouring the internet looking for more ways to spend Crypto instead of government-funded cash.
My meetups started out with 2 people 1 of which was my dad to 12 strong and growing (which does not include my dad). That may not seem like many but those 12 people have become strong and confident users of Cryptocurrency and one of them even accepts BitcoinCash for his business.
My story does not end here, and with every day there is a change with some great, some good and some not so good stories. Keep your eyes out for updates to my never ending and exciting Crypto life.

A 14-year-old's experience with Bitcoin

First-time poster here, don’t bully me, apologies for the potentially atrocious formatting :) TL;DR at the end
So in the wake of Bitcoin’s explosive rise in value and media attention, I’ve been encouraged by others to share my experience over the past few years as a miner. Here's my story (it's kinda long, you've been warned)

Humble Beginnings

It all started almost three years ago in the beginning of 2015 when Bitcoin flew under my radar. Looking into it, I admittedly wasn’t drawn in because of the decentralisation or the anonymous payments, I was hooked on the idea that anyone could get their hands on some just by running a program and leaving it to do its own thing. I know, how shallow of me. But the idea of making even a bit of money without ‘any work’ was convincing enough for 11-year-old me to do more digging into the matter.
To my disappointment, I soon found out that the era of mining Bitcoins with a PC’s CPU or GPU was long obsolete and instead it was all ASICs at that point.
So that summer, for my twelfth birthday, I got a little ASIC machine for €60, an Antminer U3. This little thing took up less space than a graphics card but could mine at 60 GH/s. Because, at the time, I didn’t have a controller device that could be kept up and running all day long so it could run the program that mined Bitcoin using the U3, I went ahead and got a Raspberry Pi. After setting up the Pi and installing all the necessary stuff (took an awfully long time), I connected it to AntPool and plugged the U3 in. Two days past and the mining pool sent the first Bitcoin I ever received to my wallet (I was using Blockchain.info). It was just 30 cents worth of BTC but I felt a bit of a rush because I was earning a bit of money through this completely new thing and the idea of that was thrilling.
Let’s back up for a second. I just used the term ‘earning’ as if I was profiting, and naive me 2 years ago was no different. In reality, I was at first oblivious to the fact that I was most likely LOSING money overall because of how much energy that little sucker was taking in. But, I was comforted thinking that using that machine was just a practical way of learning about this modern currency and that the loss of several cents’ worth of energy was acceptable in the name of education and learning.
Fast forward ten months to the wonderful summer of 2016. I had recently turned 13 and the Antminer U3 had been running on and off throughout. Various pauses and breaks in mining would be observed, as I had to manually get everything up and running after frequent breaks in the Internet connection. You’d expect my newly-turned-teenage brain to lose interest in Bitcoin as it does with many other gimmicks, but – even surprising myself – I miraculously didn’t. Good thing I maintained interest thinking about it now, not so good at the time for my parents. Why do I say this? I felt like it was time to get a little upgrade in my hardware.

Getting an upgrade

Days passed with me comparing every ASIC miner I could at that price point. It was then I set my eyes upon the Antminer S7 (same folks who did my U3, nice). I had put it up against a plethora of other miners and I figured the S7 was my best bet; the thing costs only about 10 times that of my U3 but could run at 4.73 TH/s, almost 80 times as powerful. The only problem being its power consumption was at 1300 watts, which would put a massive dent in the electricity bill and eliminate any profit I would make. Fortunately, I had a secret weapon up my sleeve – or rather my mum did. She had rented out an office outside our apartment where she would keep files and paperwork. The office’s electricity bill was a flat rate as far as I’m aware and it ended up being my saving grace because it virtually got rid of the “oh no I’m actually going to be losing money because of how much electricity I’m eating up” factor, making this whole hardware upgrade viable.
After convincing my parents, they finally agreed to shell out the requested amount, with the initial investment being paid back with time. I went to a local Bitcoin vendor and purchased 1 BTC for about $665 in cash (sigh yes, I know. $665 dollars). Shortly after, I used about 0.9 BTC to purchase the Antminer S7 and a 1600W power supply for a grand total of $600. The products would be made and shipped from China so I was definitely in for a wait.
A month passes and the package arrives at last. I connected all the wires from the power supply into the S7 and – with great anticipation – I plugged it into the wall to start its first ever run. And what do you know? An extremely loud and high-pitched whirring sound blasted out from the fans on both the power supply as well as the S7. After killing the thing, I questioned my choices. I couldn’t dare put that thing anywhere near my mum’s office in the event it drive everyone in the building absolutely nuts. I was at a loss. However, I soon recovered from my temporarily debilitated state and got working on a solution.
The first idea that came to my mind: change the fans. The stocks fans were by Evercool and spun at around 3000 RPM. The power supply used a small, robust fan that looked like a cube that must’ve spun at extremely high speeds judging by how high the sound it produced was. I got my parents to give me some more funding so I could acquire the replacement fans and I did. Bust. After installation and testing, none of the fans would work. I managed to configure the S7 to connect to my Antpool account and the machine would manage mining for several minutes running at peak performance but ultimately be automatically cut off because of how hot the machine was getting (I’m talking about 80 degrees Celsius kinda hot in that thing). The fans got refunded and I was back to the drawing board.
After combing through some forum posts and videos, I came across this video and a forum post in which people have their mining rigs placed inside a ventilated, muffled cabinet. Undertaking a project like this would be time-consuming and risky but I had no better ideas so I decided to go through with the idea anyway.
Firstly, I sought out a cabinet with suitable dimensions. I managed to get just what I needed at a second-hand IKEA shop. Great. Secondly, I went ahead and acquired some sound-absorbing acoustic foam from a local provider. Fantastic. Finally I had to get a ventilation system going within the cabinet, otherwise, all the hot air would roast the machine alive in there in a bloody mess. With the help of my dad, we found a pair cabinet fans on the Internet that were close to silent but could circulate the air well enough.
Eventually, all the materials came and, with the help of my parents, put everything together. The process took quite long time and we had a couple hiccups along the way, but we got it done and it came out pretty nice.
The moment of truth came and, to my relief, it ran so much quieter than without the cabinet. It was nowhere near silent but it reduced the noise a great deal. Soon after, I got the thing into the office and set everything up from there. Unfortunately, I was forced to underclock it because you could still hear the machine’s whining from outside the thin office door. Gunning the hashrate down about 25% to 3.7TH/s, I could lower the fan speed without risking the machine burning up. Sure, I wasn’t getting the full potential of the machine but I didn’t complain because electricity was not an issue there and it was still a whole lot better than my U3. With it up and running, I could leave it there, periodically checking to see if it was mining on Antpool.

The aftermath

In the months that followed, I was getting a solid $2.5 worth of BTC on daily basis. Half a year later, May of 2017, I had accumulated a satisfactory $600. I thought, “At this rate, I’d be able to pay my parents’ investment back in a few months” (the total investment came close to $900). Bitcoin had risen to over $1500 so I was already over the moon at that point because of how well everything was going. Little did I know…
I hit 0.5 BTC midway through September this year. The price of BTC had dropped after a sudden rise to $5000, but I couldn’t have asked for more. Although I possessed only half the amount of BTC I paid for the machine, its value was over twice that of the initial investment. I thought BTC would level off at around $4000 but nope.
In the month of October, the price skyrocketed. Since September, I had only mined 0.017 BTC but the value was already over $3000. It was just a matter of selling it, but I decided to hodl. Good thing I did.
As of November 5, I have approximately 0.52 BTC mined in total from my S7, valued at $4000. If I were to sell it right now, I’d have a profit of over $3100. And as for my miner, it’s churning out 0.0006 BTC daily, sounds like nothing but it’s still the equivalent of $5 today and I couldn’t be happier, at least with the miner and Bitcoin.
You remember that $665 for 1 BTC that I mentioned earlier? In hindsight, it would’ve been such a better idea to just keep that one Bitcoin and not do anything with it until today (in the interest of making much more money), as I’d theoretically have upwards of $7000. The idea of that still haunts me sometimes if I dwell on it too long but knowing that I’m in possession of an already hefty amount, the pain of it had numbed slightly. It’s not all doom and gloom for me from the exponential increase in Bitcoin’s value, however. Those first $0.3 payments from my humble little U3 all those years ago now are now the equivalent of over $6 today!
Bitcoin and everything it encompasses has been and still is a journey of discovery and an adventure. Looking back, starting with a modest €60 Antminer U3 to having a sum of Bitcoin equivalent to two extremely high-end gaming rigs (first thing I could think of as a comparison, sorry) has been something I can’t really describe. Through the course of the past few years, I’ve learned more about technology, I’ve unexpectedly gotten insight into economics and business and – of course – I’ve made a lot of money (if I decide to stop hodling that is).
Also, props to my parents for keeping an open mind throughout, I know some parents would be horrified at their kids being involved in something that has been used in some less-than-savoury ways and it's great knowing mine have been supportive all the way.
TL;DR got into Bitcoin mining 3 years ago at age 11 with an Antminer U3 that ran at 60 GH/s, got an Antminer S7 (4.73TH/s) and built a sound-muffling, ventilated cabinet for it. Am sat here today with $3000 profit if I decide to sell right now.

Had a thought yesterday... (sorry it's a long one).

... About OP_RETURN and the question of allowing large amounts of data to be uploaded to the block chain. I have seen and read various opinions on this. Allow me to add what might be a different perspective to the mix and see what you all think.
~~~~~~
TL;DR: Allowing large OP_RETURN uploads is a form of testing/proving the network, and whilst the demand for lots of small transactions does not yet exist, it (uploading large amounts of data) is economical. As demand for smaller transactions increases, the cost to post large OP_RETURNs will increase proportionately and so those kinds of transactions will slowly become less of the used block space. It's actually a smart way of testing and demonstrating that BSV is open for business. Proving that scaling works on the real network, before it's needed. This reduces the risk for new entrants (users, application builders etc).
~~~~~
When thinking about this yesterday I came to the conclusion that opening up OP_RETURN is actually a genius move. Let me explain.
For Bitcoin to scale we need to support large blocks. By "support" this means the entire eco-system from miners to tools that deal with parsing transactions and data. I'm not sure about you folk, but I can't think of a better way to test and exercise those systems than allowing people to post real transactions with real data attached. Comparatively speaking, you can either stress test with thousands of transactions or a single transaction with a large OP_RETURN. Sure, these are not exactly the same thing, but every day that goes on where large blocks are being produced is more proof that the network can handle large blocks and is able to propagate them. (Testing large amounts of small transactions is also advisable, but that doesn't need to be the primary method for testing block propagation and validation).
People have argued that uploading photos and the like is a silly idea, and even though I think I understand their rationale, I think there should always be the opportunity for people to upload an important file or document or photo is they so choose to do so, and they are happy to pay the fee for it. A free market in action. Miners get to decide how they manage the storage (or maybe in future that's a service provided to miners by someone else). To make sure that the use case works, however, it needs to be (and is being) tested. Plus there's the tools like Bitstagram that are making use of the feature now; creating ideas for new tools.
What all the above does though, and this is the key point I have been pondering, is that it all simply shows that the network can handle large blocks, and as time goes on, likely larger and larger blocks, and that the sky doesn't fall, like has been prophesized by the opposition, especially those that believe every single Raspberry Pi needs to be able to run a full validating node. The fact that the sky doesn't fall and the network keeps on trucking, builds up confidence in the network and its ability to scale on-chain.
Once this happens, the door is open for large numbers of transactions on a proven network. I haven't checked the exact numbers but based on what I see on BTC, a rough back of the envelope calculation yields that, for example, 32MB blocks likely allow for around 80 million transactions per day (with no or little OP_RETURN data), or about 90 Tx/s.
I hear you saying "Wait.... but we can fill up a 32MB block with a relatively small number of transactions with large OP_RETURN data, so we now need even bigger blocks!". But here's the genius part. We don't. At least not for the 32MB to be highly utilized by small transactions. (Of course larger blocks mean more support for of all types of transactions...)
... The available block space is still subject to use by people's willingness to pay the associated fees. In a recent post by Ryan Charles, and IIRC, he was talking about $120 worth of fees to upload a series of about 30 or so, high resolution photos. Fees are still sats/byte. So if people want to do small transactions they can still pay a tiny fee, even if they double or triple the sats/byte that they pay. The effect that this has though (the doubling or tripling), is that now Ryan's exercise to upload the large OP_RETURN data just doubled or tripled in price (assuming competition for block space). In other words, what I am trying to say is that people will always be more readily able to pay for and afford very small transactions (so long as they are not personally making thousands of them), even if others are using large portions of block space though large OP_RETURNS. The cost of posting larger amounts of data will scale up accordingly with the demand for regular transactions. (And even if people are making thousands of transactions, they can still decide how much they are willing to pay for them, in the context of whatever they are doing that necessitates the need to execute those transactions). The Utopian goal is to always have more block space available, or at least enough so that fees stay at a reasonable level.
So actually, whilst the block space is not being used, we shouldn't have a problem with people uploading photos and whatever they want to; it's proving the network can handle it and allowing participants of the network to test and improve their setups based on that usage. Furthermore, there are no doubt people taking notice of this fact, and seeing how BSV is providing something that neither of the other two Bitcoin projects can provide; which is a network that has demonstrated scaling in practice, whilst keeping the approach as simple and as secure as possible.

Six Hundred Microseconds.

A perspective from the Bitcoin Cash and Bitcoin Unlimited developer who discovered CVE-2018–17144.
That is about the time that Matt Corallo wanted to shave off of block validation with his pull request in 2016 to Bitcoin Core. 600µs is a lot less than what is saved with more efficient block propagation, like XThin, Compact Blocks, or now Graphene over typical links, especially those that are of similar low-end quality in network speed like Raspberry Pis are in compute speed. An optimization that was not in the focus by Core until XThin from Bitcoin Unlimited came onto the scene and kicked the Core team into gear on this issue. Furthermore, 600 microseconds is an order of magnitude or more below the variance between node validation speeds from a Raspberry Pi to a more high-end miner node and thus wholly in the range that the network already deals with. This 600 microsecond optimization now resulted in CVE-2018–17144. Certainly the most catastrophic bug in recent years, and certainly one of the most catastrophic bugs in Bitcoin ever. This bug was initially suspected to potentially cause inflation, was reported because it led to reliable crashes and confirmed by closer analysis… to be actually allowing inflation! I have consistently and repeatedly criticized hubris and arrogance in the most prominent Core developers, and done so since 2013, when the bullshitting around the 1MB block size limit started. Here we have an optimization that talks about avoiding “duplicate” validation like validation is nothing to worry about, an afterthought in Bitcoin almost. And a change that is quickly found to be good in peer reviewed, ACKed in Core-speak, in a rubber-stamp-like manner by Core developers such as Gregory Maxwell. Developers which I fully respect for their intelligence and knowledge by the way, but still, well, dislike as much for their overblown egos and underhanded discussion style as well as having done all they can to handicap Bitcoin with the 1MB limit. I also have to be honest, this change creates an unavoidable element of suspicion in me. For anyone who knows what went down and what the code paths do, it is just unavoidable to have this thought here. I like to qualify that this is not what I assert nor think is happening, but definitely crosses my mind as a potentiality! Because what is better to destroy the value of Bitcoin in the public’s eye than a silent inflation bug? What is better than creating code paths that look harmless for themselves but combined with some other, seemingly harmless rework in other areas of the code, result in utter catastrophe? And it looks like CVE-2018–17144 would eventually have become exactly this. The only thing that saved Core is their effective client diversity between revisions and someone actually noticing that there is a problem. After two years of this bug sitting around idle and exploitable. Client diversity that has been much criticized on the Bitcoin Cash side of things, but it obviously shows its advantages now. Reading the title of the original PR: “Remove duplicatable duplicate-input check from CheckTransaction” , as well as the message therein: “Benchmark results indicate this saves about 0.5–0.7ms during CheckBlock.” almost reads like it could be a sick joke being played on us all now. I always feared that someone from the bankster circles, someone injected into the Bitcoin development circles with the sole goal of wreaking unsalvageable havoc, would do exactly what happened. Injecting a silent inflation bug. Because that is what would destroy one of the very core advantages that Bitcoin has over the current status quo. That of transparency and a verifiable money supply. And, even though as a Bitcoin/BCHer, I do not see true long term prospects in Bitcoin/BTC anymore, calling the whole foundation of crypto into question just like that would have been equally disastrous to “our” variant of Bitcoin. Now, again, I am definitely not saying this is the case with PR 9049 for sure. I actually think the explanation of a young, cocky Core developer, a new “master of the universe” wreaking havoc by sheer arrogance and hubris, is the more likely explanation. People in general, but I don’t even exclude myself here, tend to believe in the competence of others if they appear just self-assured enough. This is part of the problem with attitude and psychological dynamics in this space. It creates a dangerous aura of ‘these guys know what they are doing’. I myself have done some minor work on sensitive areas in the Bitcoin Unlimited implementation. And I am working on some more “consensus critical” code for BCH now (see below). And, yes, I sometimes do lose some sleep over what could go wrong. I know I make mistakes. I have done so. I will. We all do. But I have yet to see anything resembling an admission of being imperfect by the developer in question, or any other prominent Core developer for that matter. The folks in question know exactly who I mean. There must be more reasonable folks in Core, but they are rather silent. Much worse even: In the discussion on github that follows this PR, user freetrader (a well known anonymous but still respected member of the Bitcoin Cash community who helped to create the Bitcoin Cash initial fork) asks the very valid question:
Which is answered in the, all-too-typical for Core, smug manner by Matt Corallo, notably the original author of the bug who has all reason to be a bit more careful and respectful:
The bug was disclosed in an absolutely responsible manner. As even the full disclosure on bitcoincore.org’s own pages notices, it went to a set of trustworthy people by the person who found the bug and did so in an encrypted PGP message only. This leaves the question why Core recklessly endangered the security of Bitcoin Cash as well endangering the myriad of altcoins that are out there and still susceptible with this premature and hasty publication. The back references from altcoins merging the change trickling into PR #14247 are a glimpse into this process. Now, Matt talks about “running out of time” in the above reply. But what time is that exactly? If you think hard about this, this can only be a distrust in any of the informed parties that they’ll leak this secret prematurely and thus catch Bitcoin Core with their pants down, or as a worse assumption, be actually exploited by one of the informed parties against BTC. Bitcoin Unlimited was ferociously attacked, presumably by deranged BTC supporters from the wider ‘community’, when it had a bug. And it seems a bit like Core members assumed a payback by deranged BCH supporters in kind here (I am not doubting those supporters exist), given the hints in the original disclosure that this bug has actually been discovered by someone aligned with the Bitcoin Cash side of things. But not only that, Core seems to have assumed that members on the BCH side of things who have been informed are deranged or at least irresponsible enough to leak this info to the wrong parties! I like to applaud deadalnix and the ABC team for what I was thinking the Core team should have done here as well: Bury the fix in a bit more and unrelated refactoring code so as to fix it but also to buy some more time for an upgrade. Maybe Core wasn’t creative enough to see a way to hide the problem, but then they also had no reason to blare it out like they did here. This was very irresponsible, and, and this should reach any altcoin impacted by this, this is definitely solely Bitcoin Core’s responsibility. No one else said anything in public before Core published their PR. It should also be noted by the Core team that this creates a strong disincentive to keep them in the loop with initial disclosure for anyone finding a bug. Cory Fields has talked about the risks and dangers with regards to sitting on the knowledge of a 0-day on Bitcoin Cash, and this bug discussed herein is one that was worth at least 10x more in potential damage and thus also shorting value and angry deranged people (a.k.a. “31337 crypto trading bros”) capable of violence. If a party behaves this irresponsibly, it shouldn’t be surprised if it degrades itself to a lower position in the food chain with regards to vulnerability disclosures. I am not saying I won’t inform next time I might stumble upon something, but this is not a good way to create the necessary trust. The Discovery and Disclosure Sitting in my little van by the sea on Monday, I was working on getting the new CHECKDATASIG/-VERIFY opcodes that are about to activate for Bitcoin (Cash) in November implemented on the Bitcoin Unlimited client. I have been looking at a potentially neat use case for those and am motivated to get this done. Around noon, I noticed that there is a lot of divergence in the way that signature operations counting was done in ABC vs. how it was done in Bitcoin Unlimited (BU). I agreed earlier with the BU team that I would go and port most of the CDS/-V stuff over from ABC, but I felt overwhelmed. My thoughts were that: Ok, this is doable, but this needs a lot more analysis and also many more eyeballs for review. And will take a lot longer. Sigh. While doing so, I stumbled upon this comment in the ABC code base: Check for duplicate inputs — note that this check is slow so we skip it in CheckBlock My initial reaction was a slight “Eh, WTF is going on with that comment?”. And then I looked up uses of CheckRegularTransaction in ABC, which is the renamed variant of CheckTransaction in Core (but I didn’t know at that time). I dug through the code to try to understand the logic. I noticed that block validation skips this test as it is assumed to have already happen during mempool ingress. My next thought was a bit of a sinking feeling and a “Uh-oh, I really hope the folks from ABC have thought about the difference between the mempool and block transmission and that those are distinct ways into the system. There might be a problem here!”. And then I went and thought about a way to test this. I patched an ABC node to not relay transactions even when asked and connected one unpatched and one patched node together in -regtest mode and created a transaction with a duplicate input (which the above test was skipping). Wham! assert(), Aborted. Next thought was along the lines: “Oh fuck, this doesn’t look good, gotta notify deadalnix and the crew what is lurking in ABC, this doesn’t look good at all. [email protected]#%!!”. Being aware of the danger that this could maybe be further exploited towards an actual inflation and chain-splitting bug (but I didn’t further check the specifics of this, as a node crash bug with assert() failure was already enough to be worried about), I quickly and somewhat inaccurately noted to myself (and timestamped): BitcoinABC does not check for duplicate inputs when processing a block, only when inserting a transaction into the mempool. This is dangerous as blocks can be generated with duplicate transactions and then sent through e.g. compact block missing transactions and avoid hitting the mempool, creating money out of thin air. awemany [Footnote: I timestamped this message in the BU slack, adding an innocuous situational lie of ‘Ooops, wrong channel’ to it. I also tried timestamping my findings on on my usual go-to site originstamp.org but they only submit timestamps every 24h due to the fees on Bitcoin being too high to do more often… I guess I should maybe get into the habit of doing timestamping transactions myself..] Opening up a disclosure email to deadalnix, I started to have a thought of: “Ok, actually, where is this stuff coming from, when and where did they introduce it into the code, might we be lucky and this is not in a release yet?” And then I noticed that this stuff was coming from Core. Already having written a disclosure report, I rechecked whether Core was vulnerable as well. And, once again: Wham! assert(), Aborted. I started to get shivers up my spine. Uh oh! Core has a crash bug, potentially worse. Stuff in the code since 2016. NOT good. NOT good at all. I like to say here that I actually had a feeling of this is bad, not this is good because of Core vs. Cash or something like that. I (unfortunately) still own a (for my poor soul significant) amount of BTC and for that reason and others do not like having bugs in Core either. Being a responsible citizen in this space, I then wrote the encrypted disclosure email to Wladimir, sickpig and some others, attaching a variant of the ABC and the Core patch to exploit this problem to my disclosure. I also put in a BCH address for a bounty payment to myself into that email (disclosed as proof below), as I feel this should be something worth a little performance bonus 🙂 No money has been received at the time of this writing yet. If you want to change this, you can send me BCH here: bitcoincash:qr5yuq3q40u7mxwqz6xvamkfj8tg45wyus7fhqzug5 (1NBKDco2EctDXvBv6r4hqJRPWfgX9jFpqs) I chose the handle beardnboobies as this is the first thing that came into my mind when I thought about this very discovery here. I thought: Ok, I am slowly becoming a pale nerd working on just code, with beard and manboobies. Oh well. I have noticed that this handle was — for whatever reason- taken out of the release notes that are checked into the main development branch of Bitcoin Core and is only available in the release branch / tag, being replaced with anonymous contributor on the main branch. I wonder: Do you Core guys feel this is too unprofessional to have this pseudonym appear in the main branch? Have some humor please! 🙂 By the way, a plea: I urge everyone in BCH as well as BTC (as well as impacted altcoins), to take a fine-toothed comb through the code with the goal of looking for similar issues! More specifically, I faintly remember (though might be wrong) from discussions back with Core devs on reddit in 2016 and before, that the idea that there’s a lot of “duplicate validation” between mempool and block validation was kind of en vogue back then. Potentially more code is vulnerable because it assumes that mempool validation can stand in for block validation. I suspect more, though maybe not as grave bugs, in this area. Reactions After I submitted it, I felt relief and then I started to watch the space from the back. A weird situation. Only then I also fully realized what Core contributor Cory Fields described with a bit of a different angle and on a smaller scale, the weirdness of having found a bug that you know is worth millions at least, massively impacting a $100 billion currency. The fact that I could have gone and rented hash power and shorted BTC and exploited this. But also the fact that I did not! Wladimir eventually wrote me an email that they’re preparing releases (and at that time or around it they published the PR), so I responded expressing my astonishment of the quite public handling of this serious issue. What I was amazed by in general was the long time it took for the bug to blow up to its full proportions, with the process seemingly even not over now. One thing is certainly others digging into this and realizing the full severity of this — as it turns out, yes it CAN be used to double-spend and inflate on BTC after all! — but also the time it takes from the initial PR being public, seemingly not noticed at all and the first media article being written. And then I noticed the usual spin. The “stupid BCashers can’t code and are irresponsible and what not” angle that is all too often repeated then by seemingly cerebrally insufficient Core supporters. I quote the below to gloat maybe. But also to show the world WHAT kind of bullshit the Bitcoin Cash side of things is facing here in a constant barrage. This is just from a few of the more prominent Core supporters and devs. There is, of course, a lot more folks foaming “btrash, bcash” at the mouth on reddit and twitter. Tone Vays and Jimmy Song Here we have Tone Vays, who likes to pose with the undercurrent of violence by wielding weapons on Twitter and apparently also on Youtube, discussing this bug with Jimmy Song in an unwillingly hilarious Youtube video:
Luke-Jr I like to say some words about this tweet of Luke-Jr, committing the sin of bearing false witness about us irresponsible “BCashers”…
I suspect Luke-Jr has been left in the dark about the background of this disclosure as well, not belonging to the innermost circles either. Careful observers might have noticed even more of this dynamic happening with other people. And note again: I have done everything that is necessary to make this a responsible disclosure. The initial, unobfuscated public disclosure happened by Bitcoin Core on their github! This is exactly the opposite situation compared to what Luke-Jr is describing. This is despicable.
From:Luke-Jr
Closing remarks Apart from pointing out the insane spin of some Core supporters in the preceding part, I simply want to take the opportunity now to urge caution for everyone here. Bugs lurk everywhere. Everyone is imperfect. Myself included, of course. I started to like Jihan Wu’s credo of “Don’t play hatred, don’t wish competing coins ill. Just wish and try to make BCH better” (from twitter) and see BCH and BTC in fierce but still civil competition. Civil competition obviously meaning no violence, including no violence like attacking each other’s nodes. I like to reiterate that, despite the gloating and strong words you might find in this article, I did everything to play fair. I also agree in general with Cory Fields from Core that it is not very easy to find the necessary disclosure addresses and information. He’s right about the lack of easily accessible GPG keys both on the BCH as well as — I like to add- on the BTC side of things. I didn’t find a non-retracted key of Pieter Wuille in time. I also like to note that a few things went finally completely out of the window here with this bug, for example Core’s idea of ‘the code being law’. If the code is law, does that mean that you have to accept inflation now? Or is it actually the Core devs steering the ship? Is an element of reasonableness entering the space? And yes, I sincerely believe, despite the current price ratio that BCH has a much brighter future than BTC, by being fundamentalist on the principles that matter and came along with the original white paper while not being fundamental on things that were created post-hoc — like the 1MB (now 4MW) limit in the Bitcoin Core implementation. As I also don’t think extended inflation is crucial for BTC’s operation. But anyone is free to buy or sell as they want. Let’s continue competing. Let’s civilly inform each other of bugs. May the best chain win. Finally, I like to thank Andrea Suisani, Andrew Stone and Peter Rizun for their review of this article and valuable input.

If you’re attempting to maxmimize your env hash-rate beyond additional two ports provided by Raspberry Pi, I’ve only had success with industrial-grade external USB 20-port or 10-port hubs- also available for purchase at Amazonor eBay. 3.. Raspberry Pi with CGMiner making the bitcoins. My Raspberry Pi runs almost 24/7 with some of the projects that we’ve done in the past such as OpenSIM and installing Airplay onto it so that we can send music to the amplifier to my living room and even running some P2P programs to get my latest Linux distros faster. Because it runs on a 24/7 basis that means that I’m pissing 3 watts of power Setup with the USB bitcoin miner to the USB powered hub with fan. USB hub must be at lest 1.5 - 2.0 amps. Also the Rpi heatsink and fan. You need this heatsink and cooling fan if you are overclocking the Rpi for maximum mining capability and planning to keep the raspberry pi up 24/7 without burning the core processor. As such, a Raspberry Pi can totally serve as an inexpensive crypto miner. However, the distinction is that the Raspberry Pi can mine, but doesn’t necessarily do so profitably. Mostly, this depends on the specific cryptocurrency, what it’s valued at and how much the Pi can generate each day. Following these steps will leave you with a very energy efficient bitcoin miner, as a Raspberry Pi only uses four watts of power, and a miner is typically 2.5W. Mining used to be done with computers consuming over 700W for the same process so to make a jump in savings helps repay the cost of the hardware we are using.
