Dogecoin (DOGE): The Shiba Inu Meme That Turned Into A Major Cryptocurrency

Dogecoin (DOGE): The Shiba Inu Meme That Turned Into A Major Cryptocurrency
Atsuko Sato adopted a Shiba Inu from an animal shelter, and eventually took the famous Doge picture in 2010. The picture itself is entrancing, something like a hybrid between the Mona Lisa and a disturbed Shiba Inu. It is impossible to tell what exactly the shibe is thinking, leaving people open to interpret its thoughts. Someone on the internet posted the shibe’s possible thoughts all over the image in pastel colors (below image), and the Doge meme was born, and soon proliferated across the internet. This is ultimately what led to the creation of Dogecoin, a cryptocurrency ranked #21 on CoinMarketCap with a market cap of USD 279 million. Although Dogecoin started with just a meme, it now has one of the most active communities in the crypto space, and will likely be a major cryptocurrency long term.
Billy Markus and Jackson Palmer were cryptocurrency enthusiasts who also loved the Doge meme, and that led them to launch Dogecoin on 6 December 2013. There were only 59 cryptocurrencies on CoinMarketCap when Dogecoin was listed, and Dogecoin was certainly the first memecoin. Dogecoin rapidly became successful, with the first Dogecoin rally on 19 December 2013. Dogecoin’s early success led to numerous other crypto enthusiasts launching meme and joke coins, but none of them succeeded in the long run. Dogecoin is the only memecoin that has become a major cryptocurrency, most of the others have totally failed.
Practically all of the cryptocurrencies that have launched in 2017 and 2018 utilized initial coin offerings (ICOs), making them impossible to obtain without buying them. Dogecoin on the other hand had a humble and fair launch, with zero premine, and profitable mining from the beginning. Dogecoin uses the Scrypt Proof of Work algorithm, and back when Dogecoin launched it was easy to earn significant amounts of Dogecoin with a personal or gaming computer. This made Dogecoin very attractive to crypto miners, since miners could earn numerous coins even with the cheapest mining setup, versus Litecoin mining where it took weeks or months to earn an entire Litecoin. There is definitely a psychological boost when miners receive entire coins rapidly, versus small fractions of a coin. To this day Dogecoin continues to be a #1 choice for people mining via Scrypt Proof of Work on personal computers, which causes a continuous flow of new users into the Dogecoin community. This gives Dogecoin a competitive edge over many of the newer cryptocurrencies.
What makes Dogecoin truly unique is its active and friendly community. There are many Dogecoin forums and chats, but the dogecoin subreddit is the central nerve of the Dogecoin world. Back in 2014 and 2015 Dogecoin tips were raining down from the sky in dogecoin, which caused many people that never used cryptocurrency before to begin using Dogecoin, since they would get some Dogecoins for free, and then begin using and talking about Dogecoin. This made dogecoin and Dogecoin itself fun, if not addicting. Tipping continues to this day on dogecoin.
The atmosphere of tipping and friendliness made dogecoin the perfect environment for crypto newcomers. New crypto users learned about creating their first wallet, mining cryptocurrency, trading cryptocurrency, developing crypto apps, and how to objectively analyze ongoing events in the crypto space, and were rewarded throughout the process. Compare this to the central nerve of the Bitcoin community, which is Bitcoin and Bitcointalk, which has very useful information, but a more aggressive community and barely any tipping. Fundamentally this is because the Bitcoin community is focused on making money, while the Dogecoin community is focused on giving away money to build a better world.
Dogecoin continues to onboard many new crypto users, and numerous veteran crypto users like Dogecoin and continue to buy it and use it, since that is where they started. Just like people grow up in a certain place and like to stay there or visit, many crypto users grew up in the Dogecoin community and never stop coming back.
Essentially, Dogecoin is the gateway to the crypto space, and will probably hold that position long term. There is no other crypto community that is so focused on helping others, since most crypto communities are focused on competitive money making. Therefore, Dogecoin appears to have the right stuff to stay near the top of the CoinMarketCap rankings for the foreseeable future.

Why Verge Needs DigiShield NOW! And Why DigiByte Is SAFE!

Hello everyone, I’m back! Someone asked a question recently on what exactly happened to XVG – Verge and if this could be a problem for DGB – DigiByte - Here: DigiByte vs Verge It was a great question and there have been people stating that this cannot be a problem for us because of DigiShield etc… with not much explanation after that.
I was curious and did a bit more investigating to figure out what happened and why exactly it is that we are safe. So take a read.

Some Information on Verge

Verge was founded in 2014 with code based on DogeCoin, it was initially named DogeCoinDark, it later was renamed Verge XVG in 2016. Verge has 5 mining algorithms as does DigiByte. Those being:
However, unlike DigiByte those algorithms do not run side by side. On Verge one block can only be mined by a single algorithm at any time. This means that each algorithm takes turns mining the chain.
Prior to the latest fork there was not a single line of code that forced any algo rotation. They all run in parallel but of course in the end only one block can be accepted at given height which is obvious. After the fork algo rotation is forced so only 6 blocks with the same algo out of any 10 blocks can be accepted. - srgn_

Mining Verge and The Exploit

What happened then was not a 51% attack per say, but the attacker did end up mining 99% of all new blocks so in fact he did have power of over 51% of the chain. The way that Verge is mined allowed for a timestamp exploit. Every block that is mined is dependent on the previous blocks for determining the algorithm to be used (this is part of the exploit). Also, their mining difficulty is adjusted every block (which last 30 seconds also part of the exploit). Algorithms are not picked but in fact as stated previously compete with one another. As for difficulty:
Difficulty is calculated by a version of DGW which is based on timestamps of last 12 blocks mined by the same algo. - srgn_
This kind of bug is very serious and at the foundation of Verge’s codebase. In fact, in order to fix it a fork is needed, either hard fork or soft fork!
What happened was that the hacker managed to change the time stamps on his blocks. He introduced a pair of false blocks. One which showed that the scrypt mining algorithm had been previously used, about 26 mins before, and then a second block which was mined with scrypt. The chain is set up so that it goes through the 5 different algorithms. So, the first false block shows the chain that the scrypt algorithm had been used in the recent past. This tricks it into thinking that the next algorithm to be used is scrypt. In this way, he was essentially able to mine 99% of all blocks.
Pairs of blocks are used to lower the difficulty but they need to be mined in certain order so they can pass the check of median timestamp of last 11 blocks which is performed in CBlock::AcceptBlock(). There is no tricking anything into thinking that the next algo should be x because there is no algo picking. They all just run and mine blocks constantly. There is only lowering the difficulty, passing the checks so the chain is valid and accepting this chain over chains mined by other algos. - segn_
Here is a snippet of code for what the time stamps on the blocks would look like:
SetBestChain: new best=00000000049c2d3329a3 height=2009406 trust=2009407 date=04/04/18 13:50:09 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000a307b54dfcf height=2009407 trust=2009408 date=04/04/18 12:16:51 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=00000000196f03f5727e height=2009408 trust=2009409 date=04/04/18 13:50:10 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=0000000010b42973b6ec height=2009409 trust=2009410 date=04/04/18 12:16:52 ProcessBlock: ACCEPTED (scrypt) SetBestChain: new best=000000000e0655294c73 height=2009410 trust=2009411 date=04/04/18 12:16:53 ProcessBlock: ACCEPTED (scrypt) 
Here’s the first falsified block that was introduced into the XVG chain –
As you can see there is the first fake block with a time stamp of 13:50:09 for example and the next is set to 12:15:51, the following two blocks are also a fraudulent pair and note that the next block is set to 12:16:52. So essentially, he was able to mine whole blocks - 1 second per block!

The “Fix”

This exploit was brought to public attention by ocminer on the bitcointalk forums. It seems the person was a mining pool administrator and noticed the problem after miners on the pool started to complain about a potential bug.
What happened next was that Verge developers pushed out a “fix” but in fact did not really fix the issue. What they did was simply diminish the time frame in which the blocks can be mined. The attack still was exploitable and the attacker even went on to try it again!
“The background is that the "fix" promoted by the devs simply won't fix the problem. It will just make the timeframe smaller in which the blocks can be mined / spoofed and the attack will still work, just be a bit slower.” - ocminer
Ocminer then cited DigiShield as a real fix to the issue! Stating that the fix should also stipulate that a single algo can only be used X amount of times and not be dependent on when the algo was last used. He even said that DigiByte and Myriad had the same problems and we fixed them! He cited this github repo for DigiByte:


It seems that the reason that this exploit was so lucrative was because the difficulty adjustment parameters were not enough to reduce the rewards the attacker recieved. Had the rewards per block adjusted at reasonable rate like we do in DGB then at least the rewards would have dropped significantly per block.
The attacker was able to make off with around 60 million Verge which equals about 3.6 million dollars per today’s prices.
The exploit used by the attacker depended on the fact that time stamps could be falsified firstly and secondly that the difficulty retargeting parameters were inadequate.
Let’s cover how DigiShield works more in detail. One of the DigiByte devs gave us this post about 4 years ago now, and the topic deserves revisiting and updates! I had a hard time finding good new resources and information on the details of DigiShield so I hope you’ll appreciate this review! This is everything I found for now that I could understand hopefully I get more information later and I’ll update this post.
Let’s go over some stuff on difficulty first then I’ll try giving you a way to visualise the way these systems work.
First you have to understand that mining difficulty changes over time; it has to! Look at Bitcoin’s difficulty for example – Bitcoin difficulty over the past five months. As I covered in another post (An Introduction to DigiByte Difficulty in Bitcoin is readjusted every 2016 blocks which each last about 10 mins each. This can play out over a span of 2 weeks, and that’s why you see Bitcoin’s difficulty graph as a step graph. In general, the hash power in the network increases over time as more people want to mine Bitcoin and thus the difficulty must also increase so that rewards are proportional.
The problem with non-dynamic difficulty adjustment is that it allows for pools of miners and or single entities to come into smaller coins and mine them continuously, they essentially get “free” or easily mined coins as the difficulty has not had time to adjust. This is not really a problem for Bitcoin or other large coins as they always have a lot of miners running on their chains but for smaller coins and a few years ago in crypto basically any coin other than Bitcoin was vulnerable. Once the miners had gotten their “free coins” they could then dump the chain and go mine something else – because the difficulty had adjusted. Often chains were left frozen or with very high fees and slow processing times as there was not enough hash power to mine the transactions.
This was a big problem in the beginning with DigiByte and almost even killed DogeCoin. This is where our brilliant developers came in and created DigiShield (first known as MultiShield).
These three articles are where most of my information came from for DigiShield I had to reread a the first one a few times to understand so please correct me if I make any mistakes! They are in order from most recent to oldest and also in order of relevance.
DigiShield is a system whereby the difficulty for mining DigiByte is adjusted dynamically. Every single block each at 15 seconds has difficulty adjusted for the available hashing power. This means that difficulty in DigiByte is as close as we can get to real time! There are other methods for adjusting difficulty, the first being the Bitcoin/Litecoin method (a moving average calculated every X number of blocks) then the Kimoto Gravity Well is another. The reason that DigiShield is so great is because the parameters are just right for the difficulty to be able to rise and fall in proportion to the amount of hash power available.
Note that Verge used a difficulty adjustment protocol more similar to that of DigiByte than Bitcoin. Difficulty was adjusted every block at 30 seconds. So why was Verge vulnerable to this attack? As I stated before Verge had a bug that allowed for firstly the manipulation of time stamps, and secondly did not adjust difficulty ideally.
You have to try to imagine that difficulty adjustment chases hashing power. This is because the hashing power on a chain can be seen as the “input” and the difficulty adjustment as the corresponding output. The adjustment or output created is thus dependent on the amount of hashing power input.
DigiShield was designed so that increases in mining difficulty are slightly harder to result than decreases in mining difficulty. This asymmetrical approach allows for mining to be more stable on DigiByte than other coins who use a symmetrical approach. It is a very delicate balancing act which requires the right approach or else the system breaks! Either the chain may freeze if hash power increases and then dumps or mining rewards are too high because the difficulty is not set high enough!
If you’ve ever taken any physics courses maybe one way you can understand DigiShield is if I were to define it as a dynamic asymmetrical oscillation dampener. What does this mean? Let’s cover it in simple terms, it’s difficult to understand and for me it was easier to visualise. Imagine something like this, click on it it’s a video: Caravan Weight Distribution – made easy. This is not a perfect analogy to what DigiShield does but I’ll explain my idea.
The input (hashing power) and the output (difficulty adjustment) both result in oscillations of the mining reward. These two variables are what controls mining rewards! So that caravan shaking violently back and forth imagine those are mining rewards, the weights are the parameters used for difficulty adjustment and the man’s hand pushing on the system is the hashing power. Mining rewards move back and forth (up and down) depending on the weight distribution (difficulty adjustment parameters) and the strength of the push (the amount of hashing power input to the system).
Here is a quote from the dev’s article.
“The secret to DigiShield is an asymmetrical approach to difficulty re-targeting. With DigiShield, the difficulty is allowed to decrease in larger movements than it is allowed to increase from block to block. This keeps a blockchain from getting "stuck" i.e., not finding the next block for several hours following a major drop in the net hash of coin. It is all a balancing act. You need to allow the difficulty to increase enough between blocks to catch up to a sudden spike in net hash, but not enough to accidentally send the difficulty sky high when two miners get lucky and find blocks back to back.”
AND to top it all off the solution to Verge’s time stamp manipulation bug is RIGHT HERE in DigiShield again! This was patched and in Digishield v3 problems #7
Here’s a direct quote:
“Most DigiShield v3 implementations do not get data from the most recent blocks, but begin the averaging at the MTP, which is typically 6 blocks in the past. This is ostensibly done to prevent timestamp manipulation of the difficulty.”
Moreover, DigiShield does not allow for one algorithm to mine more than 5 blocks in a row. If the next block comes in on the same algorithm then it would be blocked and would be handed off to the next algorithm.
DigiShield is a beautiful delicate yet robust system designed to prevent abuse and allow stability in mining! Many coins have adopted out technology!

Verge Needs DigiShield NOW!

The attacker has been identified as IDCToken on the bitcointalk forums. He posted recently that there are two more exploits still available in Verge which would allow for similar attacks! He said this:
“Can confirm it is still exploitable, will not abuse it futher myself but fix this problem immediately I'll give Verge some hours to solve this otherwise I'll make this public and another unpatchable problem.” - IDCToken
DigiShield could have stopped the time stamp manipulation exploit, and stopped the attacker from getting unjust rewards! Maybe a look at Verge’s difficulty chart might give a good idea of what 1 single person was able to do to a coin worth about 1 billion dollars.
Here’s DigiByte’s difficulty steady, even and fair:
Maybe our developers could help Verge somehow – but for a fee? Or it might be a good way to get our name out there, and show people why DigiByte and DigiShield are so important!


Edit - Made a few mistakes in understanding how Verge is mined I've updated the post and left the mistakes visible. Nothing else is changed and my point still stands Verge could stand to gain something from adopting DigiShield!
I hope you’ve enjoyed my article! I tried to learn as much as I could on DigiShield because I thought it was an interesting question and to help put together our DGB paper! hopefully I made no mistakes and if I did please let me know.

A Guide to What the Heck is Going On

Although be it that I don't have a complete mastery of the concept either, I will do my best to use my limited knowledge to explain what exactly the heck is going on with this mystical "Litecoin Mining" and the disappearance of AMD GPUs worldwide.
What exactly is Litecoin mining?
Litecoin mining, or cryptocurrency mining in general, is the use of processors to hash out a value and submit this work in something called "Proof of Work" that is mutually recognized. To put this in an analogy, think of a 3rd grade math classroom. The teacher writes a math problem on the board, say "2+3", and she tells the class to find the answer. Quickly, each student begins to work out the problem, and when a student thinks they've found the answer, they raise their hand and respond, "The answer is 5!". The teacher will then tell the student whether they are right or wrong, and the rest of the class will listen and understand that the one student got the answer right. Then they clap for him, recognizing his achievement and work needed to arrive to the answer. Now, in terms of mining, this difficulty is scaled to immense amounts, but the basic principle is the same. You, the miner, are the student trying to find the answer. The Litecoin master algorithm is the confirming teacher. And the rest of the miners are the other students in the classroom, recognizing your work. Litecoin itself is a derivative of Bitcoin, which is basically another cryptocurrency.
Sources: Litecoin Website and Bitcoin (something like Litecoin)
So what is so important about this answer?
In reality, nothing. It just solves a math problem. But that's all the reason. When the Litecoin algorithm sees you've found the right answer and everybody agrees you found it (so no cheating!), then it will give you a "block reward". Like the teacher handing you a piece of candy for getting the right answer. This block reward contains an amount of Litecoins.
What is a "Litecoin"?
A Litecoin is a medal or proof of work done, and it is given through the reward system aforementioned. Litecoins are just numerical values stored inside of the "blockchain", which you can think of as the classroom. All of the players of this litecoin mining are located within this classroom, located within the blockchain. When everyone recognizes your work, you are given litecoins, which can only be accessed within wallets. You may think of litecoins as a currency, like pennies or nickels. They are something that we give value, yet do not have inherent value themselves. A paper bill is just paper unless we give it value.
So what is a wallet?
Wallets are where litecoins are stored, using a private key and a public key. This private key is a hash of base 58 that is completely randomized, such that only knowing both the private and public keys allows access to this wallet. The public key is shared with others who want to send you litecoins, while you keep the private key to yourself, which allows you to spend those litecoins.
Now, the ultimate question: Why are they taking our graphics cards?!
Ah yes. Now to talk about AMD GPUs. Litecoins use the scrypt algorithm, a memory and computation intensive algorithm that requires many cores and lots of fast RAM. Graphics cards fit both of these profiles perfectly. A graphics card has hundreds or thousands of computation cores, as well as lightning fast GDDR5 memory. As such, graphics cards are snatched up by miners wanting to create money out of thin air, which is basically what they're doing.
But why AMD? Why not NVIDIA?
AMD graphics cards are more efficient at moving bits than NVIDIA graphics cards, further explained here. All you really have to know if that the AMD architecture is much more efficient for cryptocurrency mining.
But why NOW? Bitcoin/Litecoin has been around for awhile. Why are miners stealing our graphics cards NOW?
Well, to put it bluntly, it's because people want to get rich. Recently, as further adoption by companies and the media coverage of cryptocurrencies, Litecoin price has skyrocketed. I'm talking magnitudes of 100 fold. Due to this rapid increase in value, miners have been rushing for more graphics card to make more money. If you take a look at this source, you can see that cryptocurrency mining profitability is insanely high compared to Bitcoin, which is Litecoin's main competitor. Look at the right column in the table that says "Profit Ratio vs. BTC". See the numbers in the 3000% range. Yeah, that's a lot of profitability that can be taken advantage of.
Will we ever get our beloved 7950s back here in /buildapc? Q_Q
Maybe. Delving deeper into what is litecoin, I'll now explain difficulty. As you find more of these answers, with more students working to find the answer to a math problem, the teacher must create more and more difficult math problems for the students to solve, else these little 3rd graders will solve them faster than the teacher has enough candy for. In litecoin mining, this equates to difficulty level. As the difficulty increase, litecoins are harder to hash out, and the rewards diminish. As more students/miners join the blockchain, mining will start to get less and less profitable. HOWEVER. If the price of litecoin skyrockets again, mining will be able to sustain profitability, and we may be out of AMD graphics card for a LONG, LONG TIME. Not to mention, once litecoin becomes unprofitable, if it indeed does, miners will move to other derivatives of cryptocurrencies, restarting the cycle and continuing to snatch up graphics cards. It is unlikely that this trend continues, but if it does, NVIDIA may be the only option for new gamers.
Give me a TL;DR summary!
I'll try my best. Poor people are sitting in a basement making money of out thin air using our graphics cards. They are making $12 a day per graphics card by basically only paying for electricity. This trend will continue for quite some time, meaning no more AMD graphics cards for a while. If you're a gamer, look towards NVIDIA, or be prepared to throw down a lot of cash.
I obviously did not cover EVERYTHING in this post, but the main principles are there. If you want to delve deeper into this, I'd suggest doing your research and looking on the Bitcoin Forum.
EDIT: Please check out /litecoin and /litecoinmining as well. Lots of good information.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 


UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode= addnode= addnode= addnode= addnode= addnode=miner.coinedup.comdoge addnode= addnode= addnode= 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!


Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.


Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.


These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.


CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.


Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:


Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!


This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.


At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Why are the Litecoin devs keeping quiet about the impending ASIC crisis? Many people are asking for the Scrypt algorithm in Litecoin to require more memory to keep Litecoin ASIC free - are they not even going to respond?

This topic here, 351 voted and the majority wanted the proof of work function in Litecoin to be modified -
Here on the Litecoin forum itself another poll is on the front page, 169 votes and the majority want the proof of work function enhanced to use more memory -
My topic here last month got 50 upvotes and reached the top of the page on reddit, still no response from litecoin devs -
I've seen a handful of reddit topics more recently on the issue - still no response??
Are Litecoin devs just going to stick their heads in the sand and hope for the best? At least post a written response on the issue? Do they have any plan? It's too late to implement these things when half of the mining community have invested money into ASICs, the time is to do it now before they become entrenched and the centralisation of mining power begins. ASIC resistance is supposed to be Litecoins unique selling point, I really don't see why anyone would be opposed to trivially modifying the Scrypt algorithm to use more memory... (apart from people who have ordered ASICs), the same amount of coins per day will still be created no-one will be worse off.
All I see looking to the future is disadvantages:
I see no solid reasons why not to change the memory requirement of Scrypt.

Of Wolves and Weasels - Day 189 - The State of Dogecoin

Hey all! GoodShibe... on Vacation!
Please enjoy this post by Guest Writer thistime1 and tip them well ;D)
Note: To tip them directly: +dogetipbot @thistime1 xxx doge verify
I have collected as much data as I could possibly find and contacted as many major players in the Dogecoin community as I could. I hope you all find this synthesis of information informative and worthy of discussion.
Anything that was announced in the few days before this was posted may not be included here, due to me working on this for the last 2 weeks! Sorry if I missed you.
I hope to do this again, maybe even as a quarterly report.
Please take all the information presented to you here and make your own conclusions about how important each piece of data is to YOUR view of Dogecoin.
1 Doge = $0.00029 USD
Price would have to increase ~750% to be back at peak value ($0.0022/dogecoin).
1 LTC = $7.60 USD
Price would have to increase ~650% to be back at peak value ($48/litecoin).
Market Capitalization
7th of all digital currencies, ~$23 Million USD
Our market cap has been declining the last few months, most coin’s have. I am excited to know what our year-to-year price change will be as that is a better measure of change than the last 30 days.
For the past few days I have been trying to find a graph of the TOTAL market cap of all coins together over time.
I have a theory that not a lot of money is being put into cryptocurrencies at the moment, and the coins that go up in value are taking away value from others. What do you think?
I want to know if this is true, or if I am crazy. If that is somewhat true, there is a limit to how many coins will make it big.
I'd love to just see the total ALTCOIN market cap over time as well.
Hashrate = ~50GH/s
Oddly, this is about the same hashrate we had after the last halving! ASICs inbound…
I could not find what proportion of the SCRYPT hashrate we have over time, as that is the best measure of hashrate in relation to other coins.
I do have this though.
Litecoin’s hashrate is about 10 times larger than ours now.
The current block reward (recent halving) will create 90 Million Dogecoins/day or 38.7BTC at current prices.
This means that if ALL mined Dogecoins are sold every day they would only make up 3.8-7.5% off all transaction volume per day, which is around 500-1000BTC/day.
When the price stays the same, we can assume 250-500BTC of Dogecoins are bought or sold in that day. Therefore miners do not make up a large portion of the selling anymore, and they haven't for a while.
Another BIG assumption you have to make is that 38.7BTC cannot move markets. From my personally observations, the Cryptsy DOGE/BTC market controls the price of Dogecoin. I have watched the Chinese markets (BTC100, BTC38, BTER) respond to changes in price after they happen on Cryptsy. ~38BTC can have a HUGE impact on price if buy/sell walls are not there to support it.
We need more demand, but it is nice to have less pressure from miners anyways.
Liquidity is still much much higher with Litecoin though!
Transactions per Day
Dogecoin has more transactions per day Litecoin, and all other altcoins.
Sent from addresses
Dogecoin has more unique addresses sending coins per day than Litecoin, and all other altcoins.
Average Transaction Value
Average Litecoin transaction value for today was $9,380 USD.
Average Dogecoin transaction value for today was $122 USD.
Average Bitcoin transaction value for today was $3,250 USD. Dogecoin is potentially being used exactly as intended. Lots of people sending small amounts of money to each other or things.
I am stunned that the AVERAGE person sending Litecoins that day, sent almost $10K.
That is 3x higher than Bitcoin. In fact, oddly, Litecoin always has a higher average transaction value than Bitcoin since the Bitcoin bubble in late 2013. Anybody know why?
We usually DO NOT have higher transaction volumes than Litecoin, but we do consistently have ~500-1000BTC/day that is transacted, putting Dogecoin in the top 5 most traded coins.
Dogecoin Address Growth
Dogecoin has also GAINED 14,653 positive addresses in the month of June, where Litecoin has LOST 33,875. (info from bitinfocharts and currency4world)
Wikipedia Statistics (
Bitcoin traffic – Average ~9000 views in the last 90 days (highest 18614 views/day) – total views/90 days 819,193
Litecoin traffic – Average ~380 views in the last 90 days (highest 998 views/day) – total views/90 days 40,036
Dogecoin traffic – Average ~1200 views in the last 90 days (highest 8629 views/day) – total views/90 days 154,415
Circlejerking Statistics
Bitcoin recently surpassed 1 Yottahash, I believe we are up to almost 1 Yottajerk of circlejerking power. I am excited for a few years from now, when the QuantumJerk ASICs are released.
Every time I read someone calling /dogecoin a circlejerk I laugh, not because they are wrong, but because they are just stating the obvious.
Do you think there is someone in the corner of the room at NASA who just comments about how all they talk about is rockets and space?
If dreaming big and congratulating ourselves on our achievements is a circlejerk, then I guess it’s human to circlejerk. Every subreddit is a circlejerk, the only difference in /dogecoin is that you can get tips from circlejerking. (Is that prostitution?)
The main point of this section was to see how many times I could type circlejerk.
The new Dogecoin Foundation is now a legal enitiy and will have a road map of working projects
Personally I would love to see someone from the Chinese Dogecoin community represented on the Foundation. They buy and sell a lot of Dogecoins Maybe just a liason position or something.
At the very least, during fundraisers, the Chinese community should be contacted to see if they want to help out!
Dogecoin is the ONLY altcoin with the Core/Wallet/qt based off of Bitcoin 0.9. Dogecoin Core will be kept up to date and features from the Bitcoin Core will be adopted quickly. The devs are doing great so far, especially against coins with full-time PAID developers!
Unprecedented cryptocurrency modeling software will be written to test possible outcomes to changes in Dogecoin’s algorithm. Main candidates are PoS 2.0, Tendermint, and SIMD. To my knowledge, this has never been created before in all of cryptocurrency, and will definitely further highlight the abilities of Dogecoin’s development team.
A payment protocol is also being worked on.
Twitch tipping with dogetipbot will go live soon! You can sign up to be invited to the beta, here.
After Twitch tipping goes live, there will be a huge announcement
I have followed what mohland and dvorwak have said about it, here.
Price might not be so encouraging at the moment, but stay faithful. Keep up the good work. Encourage more people to join. The community is something special. I have strong faith that it will be heading to the moon!
Buy ANYTHING in Dogecoins that is for sale online. Available in over 50 countries. Only BTC, LTC, DOGE, and XRP are supported.
The biggest new Onarbor feature announcement is ability to back and re-back works and reviews. This was the top request so we're glad to finally implement it. Coming soon will be more tailored feeds where we will allow people to follow creators that interest them (will allow TwitteFB/linkedin auth to find friends/colleagues).
What can Dogecoin do better?
For a coin that has done some of the best marketing out there, we suck at getting major announcements across on multiple platforms.
I am hoping /dogecoin_pr will bring this up to par.
51.54% of Dogecoin users are on Dogecoin Core 1.6.(
Maybe merchants and such are not to keen on updating if it is not required, but maybe they just do not know about 1.7.
When 1.8 comes out, I would love to see a sticky thread on the subreddit, an announcement on the official Dogecoin Twitter and Facebook pages, an announcement on the front of the BitcoinTalk forum, as well as contacting cryptonews websites.
Dogecoin has a large social media presence and should be taking advantage of THAT!
I am concerned that there are not that many external deposits made to everyone’s dogetipbot accounts. Until there are more tipping users, I fear that we may be only be tipping coins that were tipped to us in the first place. That is not the best way to build demand. I am hoping mohland has some data on this.
I strongly believe in the tipping economy and culture of Dogecoin, and personally, that is how I think we can best build demand. Until we have more tipping users, it is up to us to build that demand, and the work could pay off.
I know you powerlemons is working on updating this, but the website is COMPLETELY MISSING a section on how to accept Dogecoin. This should be just as big as the other coloured sections!
This should be added to the “Get Dogecoin” section at the bottom of the page.
I have tried to keep it updated as much as possible, but would love the community to notify me of any changes
Josh Wise
“I have said this to a few people in the community but my two cents on this is to keep it fun, charitable, and stick to the fundamentals that made the community grow so much initially. My personal opinion (and I really have no clue what I am talking about) is that this community grew so fast because it was so much fun, anything seemed possible, everything seemed worth trying and there were not many negative undertones with anything. It seems like people are really getting wrapped up in a lot of negatives right now and that is never productive. The law of attraction will rule in the end and as long as people are positive- no matter the circumstance- the circumstance will become positive. I love this place and wish only the best for dogecoin and the community, and like I said, I have no clue as to all of the intricacies and the many moving parts past and present. Only my two cents on what I see (:
As far as upcoming projects- I am still working on some new shirts by popular demand. I would really love to either race the Dogecoin car in a few Superspeedway races next year, or try to raise money so that we can run the rear bumper all season. I am super thankful for all that has come of this and want to continue to help build the brand and awareness in any ways possible. A lot of that is really up to the community though and not me.”

“A community that is having fun, building cool things, and coming together for great causes and fun causes alike is exceptionally more valuable than one that is trying desperately to create value by finger pointing, complaining, witch hunting, attempting to market useless features, and ultimately eating itself.”
thistime1 - High Anxiety Shibe
I hope you all learned something today. I tried really hard to make sure that was the case.
Who do I love?
It's 7:41AM EST and we've found 87.49% of our initial 100 Billion DOGEs -- only 12.51% remains until our period of Hyper-inflation ends! Our Global Hashrate is up from ~44 to ~47 Gigahashes per second and our Difficulty is up from ~708 to ~724.
I Hope you enjoyed today's Guest Post by thistime1!

The Strange Birth & History of Monero, Part IV: Monero "as it is now"

You can read here part III.
You can read this whole story translated into Spanish here
This is part IV, the last but not least.
Monero - A secure, private, untreceable cryptocurrency
Notable comments in this thread:
-201: “I would like to offer 1000 MRO to the first person who creates a pool”
[tacotime offers bounty to potential pool developer. Bytecoin devs haven’t released any code for pools, and the only existent pool, minergate (in the future related to BCN interests) was closed source]
-256: “Adam back seems to like CryptoNote the better than Zerocash”
-264: “update on pools: The NOMP guy (zone117x) is looking to fork his open source software and get a pool going, so one should hopefully be up soon.”
-273: “Update on GUI: othe from VertCoin has notified me that he is working on it.”
-356: “Everyone wanting a pool, please help raise a bounty with me here:
And for the GUI:”
[5439 MRO + 0.685 BTC + 5728555.555 BCN raised for pool and 1652 XMR, 121345.46695471 BCN for the GUI wallet. Though this wallet was "rejected" as official GUI because wallet still has to be polished before building a GUI]
-437: “Yes, most Windows users should see a higher hashrate with the new build. You can thank NoodleDoodle. ”
-446: “Even faster Windows binaries have just been uploaded. Install for more hash power! Once again, it was NoodleDoodle.”
-448: “that almost doubled my hashrate again! GREAT STUFF !!!”
-461: “Noodle only started optimization today so there may be gains for your CPU in the future.”
[First day of miner optimization by NoodleDoodle, it is only May 1st]
-706: “The unstoppable NoodleDoodle has optimized the Windows build again. Hashrate should more than double. Windows is now faster than Linux. :O”
-753: “i here tft is no longer part of the project. so is he forking or relaunching bytecoin under new name and new parameters (merged mining with flatter emission curve.) also. what is the end consensus for the emission curve for monero. will it be adjusted."

[Rias, an account suspected to be related to the Bytecoin scam, dares to tag Monero as “instamine”]
-957: “It's rather bizarre that you're calling this an "instamine" scam when you're so fervently supporting BCN, which was mined 80% before entering the clearnet. Difficulty adjustments are per block, so there is no possibility of an instamine unless you don't publish your blockchain (emission is regular at the preset interval, and scales adequately with the network hash rate). What you're accusing monero of is exactly what ByteCoin did.”
[Discussion with rias drags on for SEVERAL posts]
-1016: “There is no "dev team". There is a community of people working on various aspects of the coin.
I've been keeping the repo up to date. NoodleDoodle likes to optimise his miner. TFT started the fork and also assists when things break. othe's been working on a GUI. zone117x has been working on a pool.
It's a decentralized effort to maintain the fork, not a strawman team of leet hackers who dwell in the underbellies of the internet and conspire for instamines.”
-1023: “Like I stated in IRC, I am not part of the "dev team", I never was. Just so happens I took a look at the code and changed some extremely easy to spot "errors". I then decided to release the binary because I thought MRO would benefit from it. I made this decision individually and nobody else should be culpable”
[Noodledoodle gets rid of the instaminer accusations]
-1029: “I decided to relaunch Monero so it will suit all your wishes that you had: flatter emission curve, open source optimized miner for everybody from the start, no MM with BCN/BMR and the name. New Monero will be ready tomorrow”
[people trying to capitalize mistakes is always there.]
-1030: "Pull request has been submitted and merged to update miner speed
It appears from the simplicity of the fix that there may have been deliberate crippling of the hashing algorithm from introduction with ByteCoin."
[tacotime “officially” raises suspects of possible voluntarily crippled miner]
-1053: "I don't mind the 'relaunch' or the merge-mining fork or any other new coin at all. It's inevitable that the CryptoNote progresses like scrypt into a giant mess of coins. It's not undesirable or 'wrong'. Clones fighting out among themselves is actually beneficial for Monero. Although one of them is clearly unserious and trolling by choosing the same name.
Anyway, this sudden solidarity with BCN or TFT sure is strange when none of these accounts were around for the discussions that took place 3 weeks ago. Such vested interests with no prior indications. Hmm...? "
[eizh points out the apparent organized fudding]
-1061: "There was no takeover. The original developer (who himself did a fork of bytecoin and around a dozen lines of code changes) was non-responsive and had disappeared. The original name had been cybersquatted all over the place (since the original developer did not even register any domain name much less create a web site), making it impossible to even create a suitably named web site. A bunch of us who didn't want to see the coin die who represented a huge share of the hash power and ownership of the coin decided to adopt it. We reached out to the original developer to participate in this community effort and he still didn't respond over 24 hours, so we decided to act to save the coin from neglect and actively work toward building the coin."
[smooth defends legitimacy of current “dev team” and decisions taken]
-1074: “Zerocash will be announced soon (May 18 in Oakland? but open source may not be ready then?).
Here is a synopsis of the tradeoffs compared to CyptoNote: […]"
[comparison among Zerocash y Cryptonote]
-1083: "Altcoin history shows that except in the case of premine (Tenebrix), the first implementation stays the largest by a wide margin. We're repeating that here by outpacing Bytecoin (thanks to its 80% mine prior to surfacing). No other CN coin has anywhere near the hashrate or trading volume. Go check diff in Fantom for example or the lack of activity in BCN trading.
The only CN coin out there doing something valuable is HoneyPenny, and they're open source too. If HP develops something useful, MRO can incorporate it as well. Open source gives confidence. No need for any further edge."
[eizh reminds everyone the “first mover” advantage is a real advantage]
-1132: "I decided to tidy up bitmonero GitHub rep tonight, so now there is all valuable things from latest BCN commits & Win32. Faster hash from quazarcoin is also there. So BMR rep is the freshest one.
I'm working on another good feature now, so stay tuned."
[first TFT apparition in weeks, he somehow pretends to still be the "lead dev"]
-1139: "This is not the github or website used by Monero. This github is outdated even with these updates. Only trust binaries from the first post."
[eizh tries to clarify the community, after tft interference, which are the official downloads]
-1140: “The faster hash is from NoodleDoodle and is already submitted to the moner-project github ( and included in the binaries here.
[trying to bring TFT back on board] It would be all easier if you just work together with the other guys, whats the problem? Come to irc and talk like everyone else?
[on future monero exchangers] I got confirmation from one."
[8th may 2014, othe announces NoodleDoodle optimized miner is now open source, asks TFT to collaborate and communicates an exchanger is coming]
-1146: "I'll be impressed if they [BCN/TFT shills] manage to come up with an account registered before January, but then again they could buy those.”
-1150: “Ring signatures mean that when you sign a transaction to spend an output (coins), no one looking at the block chain can tell whether you signed it or one of the other outputs you choose to mix in with yours. With a mixing factor of 5 or 10 after several transactions there are millions of possible coins all mixed together. You get "anonymity" and mixing without having to use a third party mixer.”
[smooth answering to “what are ring signatures” in layman terms]
-1170: "Someone (C++ skilled) did private optimized miner a few days ago, he got 74H/s for i5 haswell. He pointed that mining code was very un-optimized and he did essential improvements for yourself. So, high H/S is possible yet. Can the dev's core review code for that?"
[forums are talking about an individual or group of individuals with optimized miners - may 9th 2014]
-1230: "Good progress on the pool reported by NOMP dev zone117x. Stay tuned, everyone.
And remember to email your favorite exchanges about adding MRO."
-1258: "This is actually as confusing to us as you. At one point, thankful_for_today said he was okay with name change:
Then he disappeared for more than a week after the merge mining vote failed.”
