Satoshi Nakamoto gave the first Cryptocurrency. The white paper for the same was given in 2008 and a computer program in 2009.
4. What are the top three cryptocurrencies?
The following are the three cryptocurrencies:
• Bitcoin (BTC) $128bn.
• Ethereum (ETH) $19.4bn.
• XRP (XRP) $8.22bn.
5. Where can you store Cryptocurrency?
Cryptocurrencies are stored in a digital wallet, and this is accessible via public and private keys. A public key is the address of your wallet, and the private key is the one that helps you in executing the transaction.
6. Which is the safest wallet for Cryptocurrency?
The most secured wallet for Cryptocurrency is a hardware wallet. It is not connected to the internet, and thus it is free from a hacking attack. It is also known as a cold wallet.
7. From where I can purchase cryptocurrencies?
The easiest way to buy Cryptocurrency is via crypto exchange. You can several crypto exchanges like Coinbase, Bitbuy, CHANGENow, Kraken etc.
8. What are the ten popular crypto exchanges?
The following are the best ten popular crypto exchange:
  1. Coinbase
  2. Binance

  4. Cex.io
  5. Local Bitcoins
  6. Bitfinex
  7. LocalBitcoins
  8. Bittrex
  9. Coinmama
  10. Kraken
9. What are the key features of Blockchain?
We all know that Bitcoin or any other cryptocurrency runs on the Blockchain platform, which gives it some additional features like decentralization, transparency, faster speed, immutability and anonymity.
10. What is AltCoin?
It means Alternative Coin. All the cryptocurrencies other than Bitcoin are alternative coins. Similar to Bitcoin, AltCoins are not regulated by any bank. The market governs them.
11. Are cryptocurrency sites regulated?
Most cryptocurrency websites are not regulated.
12. How are Cryptocurrency and Blockchain related?
Blockchain platform aids cryptocurrency transactions, which makes use of authentication and encryption techniques. Cryptography enables technology for Cryptocurrency, thus ensuring secure transactions.
13. What is a nonce?
The mining process works on the pattern of validating transactions by solving a mathematical puzzle called proof-of-work. The latter determine a number or nonce along with a cryptographic hash algorithm to produce a hash value lower than a predefined target. The nonce is a random value used to vary the value of hash so that the final hash value meets the hash conditions.
14. How is Cryptocurrency different from other forms of payment?
Cryptocurrency runs on Blockchain technology, which gives it an advantage of immutability, cryptography, and decentralization. All the payments are recorded on the DLT, which is accessible from any part of the world. Moreover, it keeps the identity of the user anonymous.
15. Which is the best Cryptocurrency?
Several cryptocurrencies have surged into the market, and you can choose any of these. The best way to choose the right cryptocurrencies is to look at its market value and assess its performance. Some of the prominent choices are Bitcoin, Ethereum, Litecoin, XRP etc.
16. What is the worst thing that can happen while using Cryptocurrency?
One of the worst things could be you losing your private keys. These are the passwords that secure your wallet, and once they are lost, you cannot recover them.
17. What is the private key and public key?
Keys secure your cryptocurrency wallet; these are public key and private key. The public key is known to all, like your bank account number, on the hand, the private key is the password which protects your wallet and is only known to you.
18. How much should one invest in Cryptocurrency?
Well, investing in Cryptocurrency is a matter of choice. You can study how the market is performing, and based on the best performing cryptocurrency, you can choose to invest. If you are new to this, then it’s advisable that you must start small.
19. From where can one buy Bitcoin using Fiat currency?
Two of the popular choices that you have are Coinbase and Binance, where you can purchase Cryptocurrency using fiat currency.
20. Are the coins safe on exchanges?
All the exchanges have a high level of security. Besides, these are regularly updated to meet the security requirements, but it’s not advisable to leave your coins on them since they are prone to attack. Instead, you can choose a hard wallet to store your cryptocurrencies, which are considered the safest.
21. What determines the price of cryptocurrencies?
The price of cryptocurrencies is determined by the demand and supply in the market. Besides, how the market is performing also determines the price of cryptocurrencies.
22. What are some of the prominent cryptocurrencies terminologies?

Delegated Proof Of Stake Vs Proof Of Work

You probably have heard of Proof of Stake (PoS) and Proof of Work (PoW) consensus mechanisms used by popular blockchain platforms. While most people have a basic understanding of these algorithms and the cryptocurrency platforms that have integrated them, few know about what they are and how they work. The inner workings of these systems can introduce users to a healthy list of benefits from the different algorithms in the marketplace today.
To this point, we hope to highlight the key differences between Delegated Proof of Stake, Proof of Stake, and Proof of Work algorithms. Before we go further, it is important to bear in mind that these different algorithms are referred to as consensus mechanisms and they are current requirements that are used to confirm a number of transactions on a blockchain without necessarily needing a third-party.
A Brief History of Blockchain Algorithms
Being a core objective and achievement of blockchain technology, It has been revealed that when the Bitcoin network was under development, Satoshi Nakamoto, the pseudo founder of this network sought ways to have transactions on the network verified without having to seek the help of any third-party system or application. This concept empowers networks to operate with fewer intuitions charging “renter’s fees’ for utilizing their networks.
He achieved this by creating a Proof of Work algorithm. In simple terms, Proof of work can be said to be a mechanism that is used to determine how a blockchain is capable of reaching consensus. It is used to determine or find out how the network is sure that the transaction to be carried out is valid and that someone is not trying to double-spend or do something bad on the network.
The overall protocol is powered by many different nodes which today have become known as miners. With this model, much of the power can be transferred to miners and there are not as many incentives to hold on to assets. Thus, a new model emerged known as Proof of Stake in the later 2010s. This has since been altered and optimized further to create what is known today as Delegated Proof of Stake.
Proof Of Work
As mentioned earlier, Proof of Work simply refers to a mechanism that is used to validate transactions on a blockchain. The origin of this mechanism can be traced back to 1993 in a journal that was published by Moni Noar and Cynthia Dwork. While this journal talked about this mechanism or algorithm, it was not until 1999 that the term "Proof of Work" was formed by Marcus Jakobson.
Going through the Bitcoin white paper, you'll find out that it was theorized by Satoshi and his team of developers that the only way to overpower the strength of blockchain networks was to launch the 51% attack. The white paper went on to reveal that for a majority of users on the Bitcoin network not to get total control of the network, it was only best that the Proof of Work system is integrated into the network. Thus, helping to prevent the worries of a 51% attack by distributing the network across a wide enough number of nodes and having the proper incentives in place for users to hold the asset.
All and all, the application of Proof of Work in the Bitcoin network has been described as one of the central ideas on which the network was built upon and to many other blockchain technologies that have emerged since Bitcoin. Proof of Work systems gave way for a trustless and distributed system unseen by the world before.
How Proof Of Work Operates
Like most of the other crypto networks, Bitcoin users can mine their cryptos with the Proof of Work algorithm. With PoW, miners on the Bitcoin network will have to solve what is referred to as a "cryptographic puzzle" if they are to validate transactions. For a better understanding of how mining works on the PoW algorithm, one can rightly refer to it as a race where miners on the network will have to compete with each other to solve a puzzle. On the network, the answers to these puzzles are referred to as "hash".
For miners on the network, each transaction they are able to validate sees them earn the cryptocurrency of the network. In the case of Bitcoin, they get BTC coins. Aside from the crypto coins they earn, they are also rewarded transaction fees paid by users to have their transactions validated. On a PoW mining algorithm, the mathematical puzzles to be solved are complex and would require miners to have large computational power if they are to compete with the other miners on the network. The implications of this algorithm used by the Bitcoin network and a number of other crypto networks include;
Proof Of Stake
With a number of problems supposedly identified by most people in the blockchain community using Proof of Work algorithms, a search for a better algorithm or consensus mechanism was on. Most scholars sought alternatives to the PoW system and that was how the Proof of Stake consensus mechanism was discovered by Sunny King and Scott Nadal in 2012. Unlike the Proof of Work that requires miners on the network to solve mathematical puzzles if they are to earn rewards, Proof of Stake requires miners to stake or lock a specific amount of coins away if they are to validate transactions and earn rewards.
How Delegated Proof Of Stake Operates
The mathematical puzzles miners are expected to solve are not as difficult as they are on the PoW system. All miners have to prove is that they have a certain amount of coins staked or locked up somewhere. This consensus mechanism is used on the Ethereum network which is currently the second most valuable crypto platform in the world. To get an idea of how delegated Proof of Stake works on the Ethereum blockchain, we'll share an example. On the Ethereum network, if a miner owns about 4% of ETH coins, they will be able to mine 4% of all transactions that are carried out on the network. This simply means that for miners to be able to mine more and earn rewards on the network, they will have to own a large amount of ETH coins.
A delegated PoS algorithm was proposed to be a fairer version of the PoW because it offers anyone an opportunity to become a miner. Unlike the PoW system, PoS does not require large computational power for users to validate transactions. It is said to be a better version of the PoW because it ensures that anyone with a little amount of ETH can conveniently mine and earn rewards on the network, unlike the PoW algorithm where users will have to spend thousands of dollars acquiring advanced mining rigs and hardware to mine. Individuals with less advanced mining rigs will find it extremely difficult to mine on the PoW network.
In summary, these two consensus algorithms currently power a number of crypto platforms. The technologies empower blockchains to operate in an efficient manner, previously unattainable by a single machine. However, with the combined computing power of many different nodes operating across the network, both models present a great foundation for blockchain technology today.

Where is Bitcoin Going and When?

Where is Bitcoin Going and When?

The Federal Reserve and the United States government are pumping extreme amounts of money into the economy, already totaling over $484 billion. They are doing so because it already had a goal to inflate the United States Dollar (USD) so that the market can continue to all-time highs. It has always had this goal. They do not care how much inflation goes up by now as we are going into a depression with the potential to totally crash the US economy forever. They believe the only way to save the market from going to zero or negative values is to inflate it so much that it cannot possibly crash that low. Even if the market does not dip that low, inflation serves the interest of powerful people.
The impending crash of the stock market has ramifications for Bitcoin, as, though there is no direct ongoing-correlation between the two, major movements in traditional markets will necessarily affect Bitcoin. According to the Blockchain Center’s Cryptocurrency Correlation Tool, Bitcoin is not correlated with the stock market. However, when major market movements occur, they send ripples throughout the financial ecosystem which necessary affect even ordinarily uncorrelated assets.
Therefore, Bitcoin will reach X price on X date after crashing to a price of X by X date.

Stock Market Crash

The Federal Reserve has caused some serious consternation with their release of ridiculous amounts of money in an attempt to buoy the economy. At face value, it does not seem to have any rationale or logic behind it other than keeping the economy afloat long enough for individuals to profit financially and politically. However, there is an underlying basis to what is going on which is important to understand in order to profit financially.
All markets are functionally price probing systems. They constantly undergo a price-discovery process. In a fiat system, money is an illusory and a fundamentally synthetic instrument with no intrinsic value – similar to Bitcoin. The primary difference between Bitcoin is the underlying technology which provides a slew of benefits that fiat does not. Fiat, however, has an advantage in being able to have the support of powerful nation-states which can use their might to insure the currency’s prosperity.
Traditional stock markets are composed of indices (pl. of index). Indices are non-trading market instruments which are essentially summaries of business values which comprise them. They are continuously recalculated throughout a trading day, and sometimes reflected through tradable instruments such as Exchange Traded Funds or Futures. Indices are weighted by market capitalizations of various businesses.
Price theory essentially states that when a market fails to take out a new low in a given range, it will have an objective to take out the high. When a market fails to take out a new high, it has an objective to make a new low. This is why price-time charts go up and down, as it does this on a second-by-second, minute-by-minute, day-by-day, and even century-by-century basis. Therefore, market indices will always return to some type of bull market as, once a true low is formed, the market will have a price objective to take out a new high outside of its’ given range – which is an all-time high. Instruments can only functionally fall to zero, whereas they can grow infinitely.
So, why inflate the economy so much?
Deflation is disastrous for central banks and markets as it raises the possibility of producing an overall price objective of zero or negative values. Therefore, under a fractional reserve system with a fiat currency managed by a central bank – the goal of the central bank is to depreciate the currency. The dollar is manipulated constantly with the intention of depreciating its’ value.
Central banks have a goal of continued inflated fiat values. They tend to ordinarily contain it at less than ten percent (10%) per annum in order for the psyche of the general populace to slowly adjust price increases. As such, the markets are divorced from any other logic. Economic policy is the maintenance of human egos, not catering to fundamental analysis. Gross Domestic Product (GDP) growth is well-known not to be a measure of actual growth or output. It is a measure of increase in dollars processed. Banks seek to produce raising numbers which make society feel like it is growing economically, making people optimistic. To do so, the currency is inflated, though inflation itself does not actually increase growth. When society is optimistic, it spends and engages in business – resulting in actual growth. It also encourages people to take on credit and debts, creating more fictional fiat.
Inflation is necessary for markets to continue to reach new heights, generating positive emotional responses from the populace, encouraging spending, encouraging debt intake, further inflating the currency, and increasing the sale of government bonds. The fiat system only survives by generating more imaginary money on a regular basis.
Bitcoin investors may profit from this by realizing that stock investors as a whole always stand to profit from the market so long as it is managed by a central bank and does not collapse entirely. If those elements are filled, it has an unending price objective to raise to new heights. It also allows us to realize that this response indicates that the higher-ups believe that the economy could crash in entirety, and it may be wise for investors to have multiple well-thought-out exit strategies.

Economic Analysis of Bitcoin

The reason why the Fed is so aggressively inflating the economy is due to fears that it will collapse forever or never rebound. As such, coupled with a global depression, a huge demand will appear for a reserve currency which is fundamentally different than the previous system. Bitcoin, though a currency or asset, is also a market. It also undergoes a constant price-probing process. Unlike traditional markets, Bitcoin has the exact opposite goal. Bitcoin seeks to appreciate in value and not depreciate. This has a quite different affect in that Bitcoin could potentially become worthless and have a price objective of zero.
Bitcoin was created in 2008 by a now famous mysterious figure known as Satoshi Nakamoto and its’ open source code was released in 2009. It was the first decentralized cryptocurrency to utilize a novel protocol known as the blockchain. Up to one megabyte of data may be sent with each transaction. It is decentralized, anonymous, transparent, easy to set-up, and provides myriad other benefits. Bitcoin is not backed up by anything other than its’ own technology.
Bitcoin is can never be expected to collapse as a framework, even were it to become worthless. The stock market has the potential to collapse in entirety, whereas, as long as the internet exists, Bitcoin will be a functional system with a self-authenticating framework. That capacity to persist regardless of the actual price of Bitcoin and the deflationary nature of Bitcoin means that it has something which fiat does not – inherent value.
Bitcoin is based on a distributed database known as the “blockchain.” Blockchains are essentially decentralized virtual ledger books, replete with pages known as “blocks.” Each page in a ledger is composed of paragraph entries, which are the actual transactions in the block.
Blockchains store information in the form of numerical transactions, which are just numbers. We can consider these numbers digital assets, such as Bitcoin. The data in a blockchain is immutable and recorded only by consensus-based algorithms. Bitcoin is cryptographic and all transactions are direct, without intermediary, peer-to-peer.
Bitcoin does not require trust in a central bank. It requires trust on the technology behind it, which is open-source and may be evaluated by anyone at any time. Furthermore, it is impossible to manipulate as doing so would require all of the nodes in the network to be hacked at once – unlike the stock market which is manipulated by the government and “Market Makers”. Bitcoin is also private in that, though the ledge is openly distributed, it is encrypted. Bitcoin’s blockchain has one of the greatest redundancy and information disaster recovery systems ever developed.
Bitcoin has a distributed governance model in that it is controlled by its’ users. There is no need to trust a payment processor or bank, or even to pay fees to such entities. There are also no third-party fees for transaction processing. As the ledge is immutable and transparent it is never possible to change it – the data on the blockchain is permanent. The system is not easily susceptible to attacks as it is widely distributed. Furthermore, as users of Bitcoin have their private keys assigned to their transactions, they are virtually impossible to fake. No lengthy verification, reconciliation, nor clearing process exists with Bitcoin.
Bitcoin is based on a proof-of-work algorithm. Every transaction on the network has an associated mathetical “puzzle”. Computers known as miners compete to solve the complex cryptographic hash algorithm that comprises that puzzle. The solution is proof that the miner engaged in sufficient work. The puzzle is known as a nonce, a number used only once. There is only one major nonce at a time and it issues 12.5 Bitcoin. Once it is solved, the fact that the nonce has been solved is made public.
A block is mined on average of once every ten minutes. However, the blockchain checks every 2,016,000 minutes (approximately four years) if 201,600 blocks were mined. If it was faster, it increases difficulty by half, thereby deflating Bitcoin. If it was slower, it decreases, thereby inflating Bitcoin. It will continue to do this until zero Bitcoin are issued, projected at the year 2140. On the twelfth of May, 2020, the blockchain will halve the amount of Bitcoin issued when each nonce is guessed. When Bitcoin was first created, fifty were issued per block as a reward to miners. 6.25 BTC will be issued from that point on once each nonce is solved.
Unlike fiat, Bitcoin is a deflationary currency. As BTC becomes scarcer, demand for it will increase, also raising the price. In this, BTC is similar to gold. It is predictable in its’ output, unlike the USD, as it is based on a programmed supply. We can predict BTC’s deflation and inflation almost exactly, if not exactly. Only 21 million BTC will ever be produced, unless the entire network concedes to change the protocol – which is highly unlikely.
Some of the drawbacks to BTC include congestion. At peak congestion, it may take an entire day to process a Bitcoin transaction as only three to five transactions may be processed per second. Receiving priority on a payment may cost up to the equivalent of twenty dollars ($20). Bitcoin mining consumes enough energy in one day to power a single-family home for an entire week.

Trading or Investing?

The fundamental divide in trading revolves around the question of market structure. Many feel that the market operates totally randomly and its’ behavior cannot be predicted. For the purposes of this article, we will assume that the market has a structure, but that that structure is not perfect. That market structure naturally generates chart patterns as the market records prices in time. In order to determine when the stock market will crash, causing a major decline in BTC price, we will analyze an instrument, an exchange traded fund, which represents an index, as opposed to a particular stock. The price patterns of the various stocks in an index are effectively smoothed out. In doing so, a more technical picture arises. Perhaps the most popular of these is the SPDR S&P Standard and Poor 500 Exchange Traded Fund ($SPY).
In trading, little to no concern is given about value of underlying asset. We are concerned primarily about liquidity and trading ranges, which are the amount of value fluctuating on a short-term basis, as measured by volatility-implied trading ranges. Fundamental analysis plays a role, however markets often do not react to real-world factors in a logical fashion. Therefore, fundamental analysis is more appropriate for long-term investing.
The fundamental derivatives of a chart are time (x-axis) and price (y-axis). The primary technical indicator is price, as everything else is lagging in the past. Price represents current asking price and incorrectly implementing positions based on price is one of the biggest trading errors.
Markets and currencies ordinarily have noise, their tendency to back-and-fill, which must be filtered out for true pattern recognition. That noise does have a utility, however, in allowing traders second chances to enter favorable positions at slightly less favorable entry points. When you have any market with enough liquidity for historical data to record a pattern, then a structure can be divined. The market probes prices as part of an ongoing price-discovery process. Market technicians must sometimes look outside of the technical realm and use visual inspection to ascertain the relevance of certain patterns, using a qualitative eye that recognizes the underlying quantitative nature
Markets and instruments rise slower than they correct, however they rise much more than they fall. In the same vein, instruments can only fall to having no worth, whereas they could theoretically grow infinitely and have continued to grow over time. Money in a fiat system is illusory. It is a fundamentally synthetic instrument which has no intrinsic value. Hence, the recent seemingly illogical fluctuations in the market.
According to trade theory, the unending purpose of a market or instrument is to create and break price ranges according to the laws of supply and demand. We must determine when to trade based on each market inflection point as defined in price and in time as opposed to abandoning the trend (as the contrarian trading in this sub often does). Time and Price symmetry must be used to be in accordance with the trend. When coupled with a favorable risk to reward ratio, the ability to stay in the market for most of the defined time period, and adherence to risk management rules; the trader has a solid methodology for achieving considerable gains.
We will engage in a longer term market-oriented analysis to avoid any time-focused pressure. The Bitcoin market is open twenty-four-hours a day, so trading may be done when the individual is ready, without any pressing need to be constantly alert. Let alone, we can safely project months in advance with relatively high accuracy. Bitcoin is an asset which an individual can both trade and invest, however this article will be focused on trading due to the wide volatility in BTC prices over the short-term.

Technical Indicator Analysis of Bitcoin

Technical indicators are often considered self-fulfilling prophecies due to mass-market psychology gravitating towards certain common numbers yielded from them. They are also often discounted when it comes to BTC. That means a trader must be especially aware of these numbers as they can prognosticate market movements. Often, they are meaningless in the larger picture of things.
  • Volume – derived from the market itself, it is mostly irrelevant. The major problem with volume for stocks is that the US market open causes tremendous volume surges eradicating any intrinsic volume analysis. This does not occur with BTC, as it is open twenty-four-seven. At major highs and lows, the market is typically anemic. Most traders are not active at terminal discretes (peaks and troughs) because of levels of fear. Volume allows us confidence in time and price symmetry market inflection points, if we observe low volume at a foretold range of values. We can rationalize that an absolute discrete is usually only discovered and anticipated by very few traders. As the general market realizes it, a herd mentality will push the market in the direction favorable to defending it. Volume is also useful for swing trading, as chances for swing’s validity increases if an increase in volume is seen on and after the swing’s activation. Volume is steadily decreasing. Lows and highs are reached when volume is lower.
Therefore, due to the relatively high volume on the 12th of March, we can safely determine that a low for BTC was not reached.
  • VIX – Volatility Index, this technical indicator indicates level of fear by the amount of options-based “insurance” in portfolios. A low VIX environment, less than 20 for the S&P index, indicates a stable market with a possible uptrend. A high VIX, over 20, indicates a possible downtrend. VIX is essentially useless for BTC as BTC-based options do not exist. It allows us to predict the market low for $SPY, which will have an indirect impact on BTC in the short term, likely leading to the yearly low. However, it is equally important to see how VIX is changing over time, if it is decreasing or increasing, as that indicates increasing or decreasing fear. Low volatility allows high leverage without risk or rest. Occasionally, markets do rise with high VIX.
As VIX is unusually high, in the forties, we can be confident that a downtrend for the S&P 500 is imminent.
  • RSI (Relative Strength Index): The most important technical indicator, useful for determining highs and lows when time symmetry is not availing itself. Sometimes analysis of RSI can conflict in different time frames, easiest way to use it is when it is at extremes – either under 30 or over 70. Extremes can be used for filtering highs or lows based on time-and-price window calculations. Highly instructive as to major corrective clues and indicative of continued directional movement. Must determine if longer-term RSI values find support at same values as before. It is currently at 73.56.
  • Secondly, RSI may be used as a high or low filter, to observe the level that short-term RSI reaches in counter-trend corrections. Repetitions based on market movements based on RSI determine how long a trade should be held onto. Once a short term RSI reaches an extreme and stay there, the other RSI’s should gradually reach the same extremes. Once all RSI’s are at extreme highs, a trend confirmation should occur and RSI’s should drop to their midpoint.

Trend Definition Analysis of Bitcoin

Trend definition is highly powerful, cannot be understated. Knowledge of trend logic is enough to be a profitable trader, yet defining a trend is an arduous process. Multiple trends coexist across multiple time frames and across multiple market sectors. Like time structure, it makes the underlying price of the instrument irrelevant. Trend definitions cannot determine the validity of newly formed discretes. Trend becomes apparent when trades based in counter-trend inflection points continue to fail.
Downtrends are defined as an instrument making lower lows and lower highs that are recurrent, additive, qualified swing setups. Downtrends for all instruments are similar, except forex. They are fast and complete much quicker than uptrends. An average downtrend is 18 months, something which we will return to. An uptrend inception occurs when an instrument reaches a point where it fails to make a new low, then that low will be tested. After that, the instrument will either have a deep range retracement or it may take out the low slightly, resulting in a double-bottom. A swing must eventually form.
A simple way to roughly determine trend is to attempt to draw a line from three tops going upwards (uptrend) or a line from three bottoms going downwards (downtrend). It is not possible to correctly draw a downtrend line on the BTC chart, but it is possible to correctly draw an uptrend – indicating that the overall trend is downwards. The only mitigating factor is the impending stock market crash.

Time Symmetry Analysis of Bitcoin

Time is the movement from the past through the present into the future. It is a measurement in quantified intervals. In many ways, our perception of it is a human construct. It is more powerful than price as time may be utilized for a trade regardless of the market inflection point’s price. Were it possible to perfectly understand time, price would be totally irrelevant due to the predictive certainty time affords. Time structure is easier to learn than price, but much more difficult to apply with any accuracy. It is the hardest aspect of trading to learn, but also the most rewarding.
Humans do not have the ability to recognize every time window, however the ability to define market inflection points in terms of time is the single most powerful trading edge. Regardless, price should not be abandoned for time alone. Time structure analysis It is inherently flawed, as such the markets have a fail-safe, which is Price Structure. Even though Time is much more powerful, Price Structure should never be completely ignored. Time is the qualifier for Price and vice versa. Time can fail by tricking traders into counter-trend trading.
Time is a predestined trade quantifier, a filter to slow trades down, as it allows a trader to specifically focus on specific time windows and rest at others. It allows for quantitative measurements to reach deterministic values and is the primary qualifier for trends. Time structure should be utilized before price structure, and it is the primary trade criterion which requires support from price. We can see price structure on a chart, as areas of mathematical support or resistance, but we cannot see time structure.
Time may be used to tell us an exact point in the future where the market will inflect, after Price Theory has been fulfilled. In the present, price objectives based on price theory added to possible future times for market inflection points give us the exact time of market inflection points and price.
Time Structure is repetitions of time or inherent cycles of time, occurring in a methodical way to provide time windows which may be utilized for inflection points. They are not easily recognized and not easily defined by a price chart as measuring and observing time is very exact. Time structure is not a science, yet it does require precise measurements. Nothing is certain or definite. The critical question must be if a particular approach to time structure is currently lucrative or not.
We will measure it in intervals of 180 bars. Our goal is to determine time windows, when the market will react and when we should pay the most attention. By using time repetitions, the fact that market inflection points occurred at some point in the past and should, therefore, reoccur at some point in the future, we should obtain confidence as to when SPY will reach a market inflection point. Time repetitions are essentially the market’s memory. However, simply measuring the time between two points then trying to extrapolate into the future does not work. Measuring time is not the same as defining time repetitions. We will evaluate past sessions for market inflection points, whether discretes, qualified swings, or intra-range. Then records the times that the market has made highs or lows in a comparable time period to the future one seeks to trade in.
What follows is a time Histogram – A grouping of times which appear close together, then segregated based on that closeness. Time is aligned into combined histogram of repetitions and cycles, however cycles are irrelevant on a daily basis. If trading on an hourly basis, do not use hours.

Weighted Times are repetitions which appears multiple times within the same list, observed and accentuated once divided into relevant sections of the histogram. They are important in the presently defined trading time period and are similar to a mathematical mode with respect to a series. Phased times are essentially periodical patterns in histograms, though they do not guarantee inflection points
Evaluating the yearly lows, we see that BTC tends to have its lows primarily at the beginning of every year, with a possibility of it being at the end of the year. Following the same methodology, we get the middle of the month as the likeliest day. However, evaluating the monthly lows for the past year, the beginning and end of the month are more likely for lows.
Therefore, we have two primary dates from our histogram.
1/1/21, 1/15/21, and 1/29/21
2:00am, 8:00am, 12:00pm, or 10:00pm
In fact, the high for this year was February the 14th, only thirty days off from our histogram calculations.
The 8.6-Year Armstrong-Princeton Global Economic Confidence model states that 2.15 year intervals occur between corrections, relevant highs and lows. 2.15 years from the all-time peak discrete is February 9, 2020 – a reasonably accurate depiction of the low for this year (which was on 3/12/20). (Taking only the Armstrong model into account, the next high should be Saturday, April 23, 2022). Therefore, the Armstrong model indicates that we have actually bottomed out for the year!
Bear markets cannot exist in perpetuity whereas bull markets can. Bear markets will eventually have price objectives of zero, whereas bull markets can increase to infinity. It can occur for individual market instruments, but not markets as a whole. Since bull markets are defined by low volatility, they also last longer. Once a bull market is indicated, the trader can remain in a long position until a new high is reached, then switch to shorts. The average bear market is eighteen months long, giving us a date of August 19th, 2021 for the end of this bear market – roughly speaking. They cannot be shorter than fifteen months for a central-bank controlled market, which does not apply to Bitcoin. (Otherwise, it would continue until Sunday, September 12, 2021.) However, we should expect Bitcoin to experience its’ exponential growth after the stock market re-enters a bull market.
Terry Laundy’s T-Theory implemented by measuring the time of an indicator from peak to trough, then using that to define a future time window. It is similar to an head-and-shoulders pattern in that it is the process of forming the right side from a synthetic technical indicator. If the indicator is making continued lows, then time is recalculated for defining the right side of the T. The date of the market inflection point may be a price or indicator inflection date, so it is not always exactly useful. It is better to make us aware of possible market inflection points, clustered with other data. It gives us an RSI low of May, 9th 2020.
The Bradley Cycle is coupled with volatility allows start dates for campaigns or put options as insurance in portfolios for stocks. However, it is also useful for predicting market moves instead of terminal dates for discretes. Using dates which correspond to discretes, we can see how those dates correspond with changes in VIX.
Therefore, our timeline looks like:
  • 2/14/20 – yearly high ($10372 USD)
  • 3/12/20 – yearly low thus far ($3858 USD)
  • 5/9/20 – T-Theory true yearly low (BTC between 4863 and 3569)
  • 5/26/20 – hashrate difficulty halvening
  • 11/14/20 – stock market low
  • 1/15/21 – yearly low for BTC, around $8528
  • 8/19/21 – end of stock bear market
  • 11/26/21 – eighteen months from halvening, average peak from halvenings (BTC begins rising from $3000 area to above $23,312)
  • 4/23/22 – all-time high

What Is Proof of Work (PoW)?

What Is Proof of Work (PoW)?

Introduction
Proof of Work (commonly abbreviated to PoW) is a mechanism for preventing double-spends. Most major cryptocurrencies use this as their consensus algorithm. That’s just what we call a method for securing the cryptocurrency’s ledger.
Proof of Work was the first consensus algorithm to surface, and, to date, remains the dominant one. It was introduced by Satoshi Nakamoto in the 2008 Bitcoin white paper, but the technology itself was conceived long before then.
Adam Back’s HashCash is an early example of a Proof of Work algorithm in the pre-cryptocurrency days. By requiring senders to perform a small amount of computing before sending an email, receivers could mitigate spam. This computation would cost virtually nothing to a legitimate sender, but quickly add up for someone sending emails en masse.

What is a double-spend?

A double-spend occurs when the same funds are spent more than once. The term is used almost exclusively in the context of digital money — after all, you’d have a hard time spending the same physical cash twice. When you pay for a coffee today, you hand cash over to a cashier who probably locks it in a register. You can’t go to the coffee shop across the road and pay for another coffee with the same bill.
In digital cash schemes, there’s the possibility that you could. You’ve surely duplicated a computer file before — you just copy and paste it. You can email the same file to ten, twenty, fifty people.
Since digital money is just data, you need to prevent people from copying and spending the same units in different places. Otherwise, your currency will collapse in no time.
For a more in-depth look at double-spending, check out Double Spending Explained.

Why is Proof of Work necessary?

If you’ve read our guide to blockchain technology, you’ll know that users broadcast transactions to the network. Those transactions aren’t immediately considered valid, though. That only happens when they get added to the blockchain.
The blockchain is a big database that every user can see, so they can check if funds have been spent before. Picture it like this: you and three friends have a notepad. Anytime one of you wants to make a transfer of whatever units you’re using, you write it down — Alice pays Bob five units, Bob pays Carol two units, etc.
There’s another intricacy here — each time you make a transaction, you refer to the transaction where the funds came from. So, if Bob was paying Carol with two units, the entry would actually look like the following: Bob pays Carol two units from this earlier transaction with Alice.
Now, we have a way to track the units. If Bob tries to make another transaction using the same units he just sent to Carol, everyone will know immediately. The group won’t allow the transaction to be added to the notepad.
Now, this might work well in a small group. Everyone knows each other, so they’ll probably agree on which of the friends should add transactions to the notepad. What if we want a group of 10,000 participants? The notepad idea doesn’t scale well, because nobody wants to trust a stranger to manage it.
This is where Proof of Work comes in. It ensures that users aren’t spending money that they don’t have the right to spend. By using a combination of game theory and cryptography, a PoW algorithm enables anyone to update the blockchain according to the rules of the system.

How does PoW work?

Our notepad above is the blockchain. But we don’t add transactions one by one — instead, we lump them into blocks. We announce the transactions to the network, then users creating a block will include them in a candidate block. The transactions will only be considered valid once their candidate block becomes a confirmed block, meaning that it has been added to the blockchain.
Appending a block isn’t cheap, however. Proof of Work requires that a miner (the user creating the block) uses up some of their own resources for the privilege. That resource is computing power, which is used to hash the block’s data until a solution to a puzzle is found.
Hashing the block’s data means that you pass it through a hashing function to generate a block hash. The block hash works like a “fingerprint” — it’s an identity for your input data and is unique to each block.
It’s virtually impossible to reverse a block hash to get the input data. Knowing an input, however, it’s trivial for you to confirm that the hash is correct. You just have to submit the input through the function and check if the output is the same.
In Proof of Work, you must provide data whose hash matches certain conditions. But you don’t know how to get there. Your only option is to pass your data through a hash function and to check if it matches the conditions. If it doesn’t, you’ll have to change your data slightly to get a different hash. Changing even one character in your data will result in a totally different result, so there’s no way of predicting what an output might be.
As a result, if you want to create a block, you’re playing a guessing game. You typically take information on all of the transactions that you want to add and some other important data, then hash it all together. But since your dataset won’t change, you need to add a piece of information that is variable. Otherwise, you would always get the same hash as output. This variable data is what we call a nonce. It’s a number that you’ll change with every attempt, so you’re getting a different hash every time. And this is what we call mining.
Summing up, mining is the process of gathering blockchain data and hashing it along with a nonce until you find a particular hash. If you find a hash that satisfies the conditions set out by the protocol, you get the right to broadcast the new block to the network. At this point, the other participants of the network update their blockchains to include the new block.
For major cryptocurrencies today, the conditions are incredibly challenging to satisfy. The higher the hash rate on the network, the more difficult it is to find a valid hash. This is done to ensure that blocks aren’t found too quickly.
As you can imagine, trying to guess massive amounts of hashes can be costly on your computer. You’re wasting computational cycles and electricity. But the protocol will reward you with cryptocurrency if you find a valid hash.
Let’s recap what we know so far:
  • It’s expensive for you to mine.
  • You’re rewarded if you produce a valid block.
  • Knowing an input, a user can easily check its hash — non-mining users can verify that a block is valid without expending much computational power.
So far, so good. But what if you try to cheat? What’s to stop you from putting a bunch of fraudulent transactions into the block and producing a valid hash?
That’s where public-key cryptography comes in. We won’t go into depth in this article, but check out What is Public-Key Cryptography? for a comprehensive look at it. In short, we use some neat cryptographic tricks that allow any user to verify whether someone has a right to move the funds they’re attempting to spend.
When you create a transaction, you sign it. Anyone on the network can compare your signature with your public key, and check whether they match. They’ll also check if you can actually spend your funds and that the sum of your inputs is higher than the sum of your outputs (i.e., that you’re not spending more than you have).
Any block that includes an invalid transaction will be automatically rejected by the network. It’s expensive for you to even attempt to cheat. You’ll waste your own resources without any reward.
Therein lies the beauty of Proof of Work: it makes it expensive to cheat, but profitable to act honestly. Any rational miner will be seeking ROI, so they can be expected to behave in a way that guarantees revenue.

Proof of Work vs. Proof of Stake

There are many consensus algorithms, but one of the most highly-anticipated ones is Proof of Stake (PoS). The concept dates back to 2011, and has been implemented in some smaller protocols. But it has yet to see adoption in any of the big blockchains.
In Proof of Stake systems, miners are replaced with validators. There’s no mining involved and no race to guess hashes. Instead, users are randomly selected — if they’re picked, they must propose (or “forge”) a block. If the block is valid, they’ll receive a reward made up of the fees from the block’s transactions.
Not just any user can be selected, though — the protocol chooses them based on a number of factors. To be eligible, participants must lock up a stake, which is a predetermined amount of the blockchain’s native currency. The stake works like bail: just as defendants put up a large sum of money to disincentivize them from skipping trial, validators lock up a stake to disincentivize cheating. If they act dishonestly, their stake (or a portion of it) will be taken.
Proof of Stake does have some benefits over Proof of Work. The most notable one is the smaller carbon footprint — since there’s no need for high-powered mining farms in PoS, the electricity consumed is only a fraction of that consumed in PoW.
That said, it has nowhere near the track record of PoW. Although it could be perceived as wasteful, mining is the only consensus algorithm that’s proven itself at scale. In just over a decade, it has secured trillions of dollars worth of transactions. To say with certainty whether PoS can rival its security, staking needs to be properly tested in the wild.

Closing thoughts

Proof of Work was the original solution to the double-spend problem and has proven to be reliable and secure. Bitcoin proved that we don’t need centralized entities to prevent the same funds from being spent twice. With clever use of cryptography, hash functions, and game theory, participants in a decentralized environment can agree on the state of a financial database.

Bitcoin’s Security and Hash Rate Explained

Bitcoin’s Security and Hash Rate Explained
As the Bitcoin hash rate reaches new all-time highs, there’s never been a better time to discuss blockchain security and its relation to the hashing power and the Proof of Work (PoW) that feed the network. The Bitcoin system is based on a form of decentralized trust, heavily relying on cryptography. This makes its blockchain highly secure and able to be used for financial transactions and other operations requiring a trustless ledger.
Far from popular belief, cryptography dates back to thousands of years ago. The same root of the word encryption — crypt — comes from the Greek word ‘kryptos’, meaning hidden or secret. Indeed, humans have always wanted to keep some information private. The Assyrians, the Chinese, the Romans, and the Greeks, they all tried over the centuries to conceal some information like trade deals or manufacturing secrets by using symbols or ciphers carved in stone or leather. In 1900 BC, Egyptians used hieroglyphics and experts often refer to them as the first example of cryptography.
Back to our days, Bitcoin uses cryptographic technologies such as:
  1. Cryptographic hash functions (i.e. SHA-256 and RIPEMD-160)
  2. Public Key Cryptography (i.e. ECDSA — the Elliptic Curve Digital Signature Algorithm)
While Public Key Cryptography, bitcoin addresses, and digital signatures are used to provide ownership of bitcoins, the SHA-256 hash function is used to verify data and block integrity and to establish the chronological order of the blockchain. A cryptographic hash function is a mathematical function that verifies the integrity of data by transforming it into a unique unidentifiable code.
Here is a graphic example to make things more clear:

– Extract from the MOOC (Massive Open Online Course) in Digital Currencies at the University of Nicosia.
Furthermore, hash functions are used as part of the PoW algorithm, which is a prominent part of the Bitcoin mining algorithm and this is what is of more interest to understand the security of the network. Mining creates new bitcoins in each block, almost like a central bank printing new money and creates trust by ensuring that transactions are confirmed only when enough computational power is devoted to the block that contains them. More blocks mean more computation, which means more trust.
With PoW, miners compete against each other to complete transactions on the network and get rewarded. Basically they need to solve a complicated mathematical puzzle and a possibility to easily prove the solution. The more hashing power, the higher the chance to resolve the puzzle and therefore perform the proof of work. In more simple words, bitcoins exist thanks to a peer to peer network that helps validate transactions in the ledger and provides enough trust to avoid that a third party is involved in the process. It also exists because miners give it life by resolving that computational puzzle, through the mining reward incentive they are receiving.

Delegated Proof Of Stake Vs Proof Of Work

Delegated Proof Of Stake Vs Proof Of Work
You probably have heard of Proof of Stake (PoS) and Proof of Work (PoW) consensus mechanisms used by popular blockchain platforms. While most people have a basic understanding of these algorithms and the cryptocurrency platforms that have integrated them, few know about what they are and how they work. The inner workings of these systems can introduce users to a healthy list of benefits from the different algorithms in the marketplace today.
To this point, we hope to highlight the key differences between Delegated Proof of Stake, Proof of Stake, and Proof of Work algorithms. Before we go further, it is important to bear in mind that these different algorithms are referred to as consensus mechanisms and they are current requirements that are used to confirm a number of transactions on a blockchain without necessarily needing a third-party.

https://preview.redd.it/fuvr8de5ns541.jpg?width=2134&format=pjpg&auto=webp&s=6c2f9d3105845d0d4ed93f44f9ccb2c93da84c2c

A Brief History of Blockchain Algorithms

Being a core objective and achievement of blockchain technology, It has been revealed that when the Bitcoin network was under development, Satoshi Nakamoto, the pseudo founder of this network sought ways to have transactions on the network verified without having to seek the help of any third-party system or application. This concept empowers networks to operate with fewer intuitions charging “renter’s fees’ for utilizing their networks.
He achieved this by creating a Proof of Work algorithm. In simple terms, Proof of work can be said to be a mechanism that is used to determine how a blockchain is capable of reaching consensus. It is used to determine or find out how the network is sure that the transaction to be carried out is valid and that someone is not trying to double-spend or do something bad on the network.
The overall protocol is powered by many different nodes which today have become known as miners. With this model, much of the power can be transferred to miners and there are not as many incentives to hold on to assets. Thus, a new model emerged known as Proof of Stake in the later 2010s. This has since been altered and optimized further to create what is known today as Delegated Proof of Stake.

Proof Of Work

As mentioned earlier, Proof of Work simply refers to a mechanism that is used to validate transactions on a blockchain. The origin of this mechanism can be traced back to 1993 in a journal that was published by Moni Noar and Cynthia Dwork. While this journal talked about this mechanism or algorithm, it was not until 1999 that the term "Proof of Work" was formed by Marcus Jakobson.
Going through the Bitcoin white paper, you'll find out that it was theorized by Satoshi and his team of developers that the only way to overpower the strength of blockchain networks was to launch the 51% attack. The white paper went on to reveal that for a majority of users on the Bitcoin network not to get total control of the network, it was only best that the Proof of Work system is integrated into the network. Thus, helping to prevent the worries of a 51% attack by distributing the network across a wide enough number of nodes and having the proper incentives in place for users to hold the asset.
All and all, the application of Proof of Work in the Bitcoin network has been described as one of the central ideas on which the network was built upon and to many other blockchain technologies that have emerged since Bitcoin. Proof of Work systems gave way for a trustless and distributed system unseen by the world before.

How Proof Of Work Operates

Like most of the other crypto networks, Bitcoin users can mine their cryptos with the Proof of Work algorithm. With PoW, miners on the Bitcoin network will have to solve what is referred to as a "cryptographic puzzle" if they are to validate transactions. For a better understanding of how mining works on the PoW algorithm, one can rightly refer to it as a race where miners on the network will have to compete with each other to solve a puzzle. On the network, the answers to these puzzles are referred to as "hash".
For miners on the network, each transaction they are able to validate sees them earn the cryptocurrency of the network. In the case of Bitcoin, they get BTC coins. Aside from the crypto coins they earn, they are also rewarded transaction fees paid by users to have their transactions validated. On a PoW mining algorithm, the mathematical puzzles to be solved are complex and would require miners to have large computational power if they are to compete with the other miners on the network. The implications of this algorithm used by the Bitcoin network and a number of other crypto networks include;
  • New transactions are broadcasted to all on the network
  • Miners will have to compete to compute a hash value that is in correlations or matches that of the transaction.
  • The very first miner on the network to solve the puzzle gets the reward and the transaction fee paid by the user

Proof Of Stake

With a number of problems supposedly identified by most people in the blockchain community using Proof of Work algorithms, a search for a better algorithm or consensus mechanism was on. Most scholars sought alternatives to the PoW system and that was how the Proof of Stake consensus mechanism was discovered by Sunny King and Scott Nadal in 2012. Unlike the Proof of Work that requires miners on the network to solve mathematical puzzles if they are to earn rewards, Proof of Stake requires miners to stake or lock a specific amount of coins away if they are to validate transactions and earn rewards.

How Delegated Proof Of Stake Operates

The mathematical puzzles miners are expected to solve are not as difficult as they are on the PoW system. All miners have to prove is that they have a certain amount of coins staked or locked up somewhere. This consensus mechanism is used on the Ethereum network which is currently the second most valuable crypto platform in the world. To get an idea of how delegated Proof of Stake works on the Ethereum blockchain, we'll share an example. On the Ethereum network, if a miner owns about 4% of ETH coins, they will be able to mine 4% of all transactions that are carried out on the network. This simply means that for miners to be able to mine more and earn rewards on the network, they will have to own a large amount of ETH coins.
A delegated PoS algorithm was proposed to be a fairer version of the PoW because it offers anyone an opportunity to become a miner. Unlike the PoW system, PoS does not require large computational power for users to validate transactions. It is said to be a better version of the PoW because it ensures that anyone with a little amount of ETH can conveniently mine and earn rewards on the network, unlike the PoW algorithm where users will have to spend thousands of dollars acquiring advanced mining rigs and hardware to mine. Individuals with less advanced mining rigs will find it extremely difficult to mine on the PoW network.
In summary, these two consensus algorithms currently power a number of crypto platforms. The technologies empower blockchains to operate in an efficient manner, previously unattainable by a single machine. However, with the combined computing power of many different nodes operating across the network, both models present a great foundation for blockchain technology today.

Programmers solve a MIT puzzle (resembling Proof of Work), Antminer salutes them in coinbase message

https://www.csail.mit.edu/news/programmers-solve-mits-20-year-old-cryptographic-puzzle
https://blockchair.com/bitcoin/block/573138
Twenty years ago MIT introduced a puzzle that was specifically designed to not be parallelizable, predicting that it wouldn't be solvable in 35 years.
If I'm getting it right it involves computing a square root of a number a fixed number of times. There is no shortcuts to this, and it it not parallelizable: you need the previous root to compute the next one. (I also suppose that it is easy to verify the solution)
As such it makes for a neat Proof of Work algorithm. Even if it doens't fit the PoW Bitcoin currently has (need to be able to distribute the work), I thought that this was a neat piece of news, and some fresh air in current events.

Cryptocurrency and the taxation difficulties it faces.

Cryptocurrencies have actually remained in the news just recently since tax authorities think they can be utilized to wash cash and avert taxes. Even the Supreme Court selected an Unique Examining Group on Black Cash advised that trading in such currency be prevented. While China was reported to have actually prohibited some its biggest Bitcoin trading operators, nations such as the U.S.A. and Canada have laws in location to limit stock sell cryptocurrency.

What is Cryptocurrency?
Cryptocurrency, as the name recommends, utilizes encrypted codes to effect a deal. These codes are acknowledged by other computer systems in the user neighborhood. Rather of utilizing paper currency, an online journal is upgraded by regular accounting entries. The purchaser's account is debited and the seller's account is credited with such currency.
How are Deals Made on Cryptocurrency?
When a deal is started by one user, her computer system sends a public cipher or public secret that connects with the personal cipher of the individual getting the currency. If the receiver accepts the deal, the starting computer system connects a piece of code onto a block of numerous such encrypted codes that is understood to every user in the network. Unique users called 'Miners' can connect the additional code to the openly shared block by resolving a cryptographic puzzle and make more cryptocurrency while doing so. As soon as a miner validates a deal, the record in the block can not be altered or erased.
BitCoin, for instance, can be utilized on mobile phones also to enact purchases. All you require do is let the receiver scan a QR code from an app on your mobile phone or bring them deal with to deal with by making use of Near Field Interaction (NFC). Keep in mind that this is extremely comparable to regular online wallets such as PayTM or MobiQuick.
Die-hard users swear by BitCoin for its decentralized nature, global approval, privacy, permanence of deals and information security. Unlike paper currency, no Reserve bank manages inflationary pressures on cryptocurrency. Deal journals are saved in a Peer-to-Peer network. They also demand that they have access to the best alert apps to ensure that you get up to date information on where the market is heading. That implies every computer system chips in its computing power and copies of databases are kept on every such node in the network. Banks, on the other hand, shop deal information in main repositories which remain in the hands of personal people employed by the company.
How Can Cryptocurrency be utilized for Cash Laundering?
The really reality that there is no control over cryptocurrency deals by Reserve bank or tax authorities implies that deals can not constantly be tagged to a specific person. This implies that we do not understand whether the transactor has actually gotten the shop of worth lawfully or not. The transactee's shop is likewise suspect as no one can inform what factor to consider was provided for the currency got.

Bitcoin is a digital currency created in January 2009. It follows the ideas set out in a white paper by the mysterious Satoshi Nakamoto, whose true identity is yet to be verified. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government-issued currencies.
There are no physical bitcoins, only balances kept on a public ledger in the cloud, that – along with all Bitcoin transactions – is verified by a massive amount of computing power. Bitcoins are not issued or backed by any banks or governments, nor are individual bitcoins valuable as a commodity. Despite it not being legal tender, Bitcoin charts high on popularity, and has triggered the launch of other virtual currencies collectively referred to as Altcoins.
Understanding Bitcoin Bitcoin is a type of cryptocurrency: Balances are kept using public and private "keys," which are long strings of numbers and letters linked through the mathematical encryption algorithm that was used to create them. The public key (comparable to a bank account number) serves as the address which is published to the world and to which others may send bitcoins. The private key (comparable to an ATM PIN) is meant to be a guarded secret and only used to authorize Bitcoin transmissions. Style notes: According to the official Bitcoin Foundation, the word "Bitcoin" is capitalized in the context of referring to the entity or concept, whereas "bitcoin" is written in the lower case when referring to a quantity of the currency (e.g. "I traded 20 bitcoin") or the units themselves. The plural form can be either "bitcoin" or "bitcoins."
How Bitcoin Works Bitcoin is one of the first digital currencies to use peer-to-peer technology to facilitate instant payments. The independent individuals and companies who own the governing computing power and participate in the Bitcoin network, also known as "miners," are motivated by rewards (the release of new bitcoin) and transaction fees paid in bitcoin. These miners can be thought of as the decentralized authority enforcing the credibility of the Bitcoin network. New bitcoin is being released to the miners at a fixed, but periodically declining rate, such that the total supply of bitcoins approaches 21 million. One bitcoin is divisible to eight decimal places (100 millionths of one bitcoin), and this smallest unit is referred to as a Satoshi. If necessary, and if the participating miners accept the change, Bitcoin could eventually be made divisible to even more decimal places. Bitcoin mining is the process through which bitcoins are released to come into circulation. Basically, it involves solving a computationally difficult puzzle to discover a new block, which is added to the blockchain and receiving a reward in the form of a few bitcoins. The block reward was 50 new bitcoins in 2009; it decreases every four years. As more and more bitcoins are created, the difficulty of the mining process – that is, the amount of computing power involved – increases. The mining difficulty began at 1.0 with Bitcoin's debut back in 2009; at the end of the year, it was only 1.18. As of February 2019, the mining difficulty is over 6.06 billion. Once, an ordinary desktop computer sufficed for the mining process; now, to combat the difficulty level, miners must use faster hardware like Application-Specific Integrated Circuits (ASIC), more advanced processing units like Graphic Processing Units (GPUs), etc.
What's a Bitcoin Worth? In 2017 alone, the price of Bitcoin rose from a little under $1,000 at the beginning of the year to close to $19,000, ending the year more than 1,400% higher. Bitcoin's price is also quite dependent on the size of its mining network since the larger the network is, the more difficult – and thus more costly – it is to produce new bitcoins. As a result, the price of bitcoin has to increase as its cost of production also rises. The Bitcoin mining network's aggregate power has more than tripled over the past twelve months.
How Bitcoin Began
Aug. 18, 2008: The domain name bitcoin.org is registered. Today, at least, this domain is "WhoisGuard Protected," meaning the identity of the person who registered it is not public information.
Oct. 31, 2008: Someone using the name Satoshi Nakamoto makes an announcement on The Cryptography Mailing list at metzdowd.com: "I've been working on a new electronic cash system that's fully peer-to-peer, with no trusted third party. The paper is available at http://www.bitcoin.org/bitcoin.pdf." This link leads to the now-famous white paper published on bitcoin.org entitled "Bitcoin: A Peer-to-Peer Electronic Cash System." This paper would become the Magna Carta for how Bitcoin operates today.
Jan. 3, 2009: The first Bitcoin block is mined, Block 0. This is also known as the "genesis block" and contains the text: "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks," perhaps as proof that the block was mined on or after that date, and perhaps also as relevant political commentary.
Jan. 8, 2009: The first version of the Bitcoin software is announced on The Cryptography Mailing list.
Jan. 9, 2009: Block 1 is mined, and Bitcoin mining commences in earnest.
Who Invented Bitcoin?
No one knows. Not conclusively, at any rate. Satoshi Nakamoto is the name associated with the person or group of people who released the original Bitcoin white paper in 2008 and worked on the original Bitcoin software that was released in 2009. The Bitcoin protocol requires users to enter a birthday upon signup, and we know that an individual named Satoshi Nakamoto registered and put down April 5 as a birth date. And that's about it.
Before Satoshi
Though it is tempting to believe the media's spin that Satoshi Nakamoto is a solitary, quixotic genius who created Bitcoin out of thin air, such innovations do not happen in a vacuum. All major scientific discoveries, no matter how original-seeming, were built on previously existing research. There are precursors to Bitcoin: Adam Back’s Hashcash, invented in 1997, and subsequently Wei Dai’s b-money, Nick Szabo’s bit gold and Hal Finney’s Reusable Proof of Work. The Bitcoin white paper itself cites Hashcash and b-money, as well as various other works spanning several research fields.
Why Is Satoshi Anonymous?
There are two primary motivations for keeping Bitcoin's inventor keeping his or her or their identity secret. One is privacy. As Bitcoin has gained in popularity – becoming something of a worldwide phenomenon – Satoshi Nakamoto would likely garner a lot of attention from the media and from governments.
The other reason is safety. Looking at 2009 alone, 32,489 blocks were mined; at the then-reward rate of 50 BTC per block, the total payout in 2009 was 1,624,500 BTC, which at today’s prices is over $900 million. One may conclude that only Satoshi and perhaps a few other people were mining through 2009 and that they possess a majority of that $900 million worth of BTC. Someone in possession of that much BTC could become a target of criminals, especially since bitcoins are less like stocks and more like cash, where the private keys needed to authorize spending could be printed out and literally kept under a mattress. While it's likely the inventor of Bitcoin would take precautions to make any extortion-induced transfers traceable, remaining anonymous is a good way for Satoshi to limit exposure.
The Suspects
Numerous people have been suggested as possible Satoshi Nakamoto by major media outlets. Oct. 10, 2011, The New Yorker published an article speculating that Nakamoto might be Irish cryptography student Michael Clear or economic sociologist Vili Lehdonvirta. A day later, Fast Company suggested that Nakamoto could be a group of three people – Neal King, Vladimir Oksman and Charles Bry – who together appear on a patent related to secure communications that were filed two months before bitcoin.org was registered. A Vice article published in May 2013 added more suspects to the list, including Gavin Andresen, the Bitcoin project’s lead developer; Jed McCaleb, co-founder of now-defunct Bitcoin exchange Mt. Gox; and famed Japanese mathematician Shinichi Mochizuki.
In December 2013, Techcrunch published an interview with researcher Skye Grey who claimed textual analysis of published writings shows a link between Satoshi and bit-gold creator Nick Szabo. And perhaps most famously, in March 2014, Newsweek ran a cover article claiming that Satoshi is actually an individual named Satoshi Nakamoto – a 64-year-old Japanese-American engineer living in California. The list of suspects is long, and all the individuals deny being Satoshi.
Can Satoshi's Identity Be Proven?
It would seem even early collaborators on the project don’t have verifiable proof of Satoshi’s identity. To reveal conclusively who Satoshi Nakamoto is, a definitive link would need to be made between his/her activity with Bitcoin and his/her identity. That could come in the form of linking the party behind the domain registration of bitcoin.org, email and forum accounts used by Satoshi Nakamoto, or ownership of some portion of the earliest mined bitcoins. Even though the bitcoins Satoshi likely possesses are traceable on the blockchain, it seems he/she has yet to cash them out in a way that reveals his/her identity. If Satoshi were to move his/her bitcoins to an exchange today, this might attract attention, but it seems unlikely that a well-funded and successful exchange would betray a customer's privacy.
Receiving Bitcoins As Payment
Bitcoins can be accepted as a means of payment for products sold or services provided. If you have a brick and mortar store, just display a sign saying “Bitcoin Accepted Here” and many of your customers may well take you up on it; the transactions can be handled with the requisite hardware terminal or wallet address through QR codes and touch screen apps. An online business can easily accept bitcoins by just adding this payment option to the others it offers, like credit cards, PayPal, etc. Online payments will require a Bitcoin merchant tool (an external processor like Coinbase or BitPay).
Working For Bitcoins
Those who are self-employed can get paid for a job in bitcoins. There are several websites/job boards which are dedicated to the digital currency:
Work For Bitcoin brings together work seekers and prospective employers through its websiteCoinality features jobs – freelance, part-time and full-time – that offer payment in bitcoins, as well as Dogecoin and LitecoinJobs4Bitcoins, part of reddit.comBitGigs
Bitcoin From Interest Payments
Another interesting way (literally) to earn bitcoins is by lending them out and being repaid in the currency. Lending can take three forms – direct lending to someone you know; through a website which facilitates peer-to-peer transactions, pairing borrowers and lenders; or depositing bitcoins in a virtual bank that offers a certain interest rate for Bitcoin accounts. Some such sites are Bitbond, BitLendingClub, and BTCjam. Obviously, you should do due diligence on any third-party site.
Bitcoins From Gambling
It’s possible to play at casinos that cater to Bitcoin aficionados, with options like online lotteries, jackpots, spread betting, and other games. Of course, the pros and cons and risks that apply to any sort of gambling and betting endeavors are in force here too.
Investing in Bitcoins
There are many Bitcoin supporters who believe that digital currency is the future. Those who endorse it are of the view that it facilitates a much faster, no-fee payment system for transactions across the globe. Although it is not itself any backed by any government or central bank, bitcoin can be exchanged for traditional currencies; in fact, its exchange rate against the dollar attracts potential investors and traders interested in currency plays. Indeed, one of the primary reasons for the growth of digital currencies like Bitcoin is that they can act as an alternative to national fiat money and traditional commodities like gold.
In March 2014, the IRS stated that all virtual currencies, including bitcoins, would be taxed as property rather than currency. Gains or losses from bitcoins held as capital will be realized as capital gains or losses, while bitcoins held as inventory will incur ordinary gains or losses.
Like any other asset, the principle of buying low and selling high applies to bitcoins. The most popular way of amassing the currency is through buying on a Bitcoin exchange, but there are many other ways to earn and own bitcoins. Here are a few options which Bitcoin enthusiasts can explore.
Risks of Bitcoin Investing
Though Bitcoin was not designed as a normal equity investment (no shares have been issued), some speculative investors were drawn to the digital money after it appreciated rapidly in May 2011 and again in November 2013. Thus, many people purchase bitcoin for its investment value rather than as a medium of exchange.
However, their lack of guaranteed value and digital nature means the purchase and use of bitcoins carries several inherent risks. Many investor alerts have been issued by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), the Consumer Financial Protection Bureau (CFPB), and other agencies.
The concept of a virtual currency is still novel and, compared to traditional investments, Bitcoin doesn't have much of a long-term track record or history of credibility to back it. With their increasing use, bitcoins are becoming less experimental every day, of course; still, after eight years, they (like all digital currencies) remain in a development phase, still evolving. "It is pretty much the highest-risk, highest-return investment that you can possibly make,” says Barry Silbert, CEO of Digital Currency Group, which builds and invests in Bitcoin and blockchain companies.
Bitcoin Regulatory Risk
Investing money into Bitcoin in any of its many guises is not for the risk-averse. Bitcoins are a rival to government currency and may be used for black market transactions, money laundering, illegal activities or tax evasion. As a result, governments may seek to regulate, restrict or ban the use and sale of bitcoins, and some already have. Others are coming up with various rules. For example, in 2015, the New York State Department of Financial Services finalized regulations that would require companies dealing with the buy, sell, transfer or storage of bitcoins to record the identity of customers, have a compliance officer and maintain capital reserves. The transactions worth $10,000 or more will have to be recorded and reported.
Although more agencies will follow suit, issuing rules and guidelines, the lack of uniform regulations about bitcoins (and other virtual currency) raises questions over their longevity, liquidity, and universality.
Security Risk of Bitcoins
Bitcoin exchanges are entirely digital and, as with any virtual system, are at risk from hackers, malware and operational glitches. If a thief gains access to a Bitcoin owner's computer hard drive and steals his private encryption key, he could transfer the stolen Bitcoins to another account. (Users can prevent this only if bitcoins are stored on a computer which is not connected to the internet, or else by choosing to use a paper wallet – printing out the Bitcoin private keys and addresses, and not keeping them on a computer at all.) Hackers can also target Bitcoin exchanges, gaining access to thousands of accounts and digital wallets where bitcoins are stored. One especially notorious hacking incident took place in 2014, when Mt. Gox, a Bitcoin exchange in Japan, was forced to close down after millions of dollars worth of bitcoins were stolen.
This is particularly problematic once you remember that all Bitcoin transactions are permanent and irreversible. It's like dealing with cash: Any transaction carried out with bitcoins can only be reversed if the person who has received them refunds them. There is no third party or a payment processor, as in the case of a debit or credit card – hence, no source of protection or appeal if there is a problem.
Insurance Risk
Some investments are insured through the Securities Investor Protection Corporation. Normal bank accounts are insured through the Federal Deposit Insurance Corporation (FDIC) up to a certain amount depending on the jurisdiction. Bitcoin exchanges and Bitcoin accounts are not insured by any type of federal or government program.
Risk of Bitcoin Fraud
While Bitcoin uses private key encryption to verify owners and register transactions, fraudsters and scammers may attempt to sell false bitcoins. For instance, in July 2013, the SEC brought legal action against an operator of a Bitcoin-related Ponzi scheme.
Market Risk
Like with any investment, Bitcoin values can fluctuate. Indeed, the value of the currency has seen wild swings in price over its short existence. Subject to high volume buying and selling on exchanges, it has a high sensitivity to “news." According to the CFPB, the price of bitcoins fell by 61% in a single day in 2013, while the one-day price drop in 2014 has been as big as 80%.
If fewer people begin to accept Bitcoin as a currency, these digital units may lose value and could become worthless. There is already plenty of competition, and though Bitcoin has a huge lead over the other 100-odd digital currencies that have sprung up, thanks to its brand recognition and venture capital money, a technological break-through in the form of a better virtual coin is always a threat.
Bitcoin's Tax Risk
As bitcoin is ineligible to be included in any tax-advantaged retirement accounts, there are no good, legal options to shield investments from taxation.

Before Bitcoin: The Digital Currency Revolution

Before Bitcoin: The Digital Currency Revolution
https://preview.redd.it/b4d7bm72lcx31.png?width=1903&format=png&auto=webp&s=feaf5a4e74b071cd4d418bce41972f79c96b2b0f
When people think of digital currencies, most might think of cryptocurrencies like Bitcoin. However, Bitcoin was not the first attempt at creating a digital currency. In fact, many different people have tried to create digital currencies in various forms for nearly 40 years. The earliest efforts to create a digital currency go all the way back to the early 1980s.
Many of the ideas and concepts that led to the creation of Bitcoin came directly in response to the many failed attempts at creating digital currencies in the past, and by finding solutions to the problems that caused many early digital currencies to fail. In this blog, we look at the history of digital currencies that came before (and would later inspire) the creation of Bitcoin.
Computer scientist David Chaum is regarded as the first person to release a white paper on digital currency in 1982. The paper titled Blind Signatures for Untraceable Payments proposed a new digital currency in response to a sharp increase in electronic transactions at the time. The article was also the first to conceptualize an anonymous digital currency. In 1990, Chaum launched DigiCash. DigiCash made its first electronic transaction in 1994 using a new digital currency called eCash.
DigiCash was the first to use protocols such as public-key cryptography and blind signatures to ensure a user’s anonymity. By using these protocols, third parties did not have access to personal information contained in online transactions. Advancements in both public and private key cryptography allowed the electronic payment system to become untraceable by a bank, government, or third party. However, the system of blind signatures that allowed users to remain anonymous required a central authority such as a bank to ensure that the funds were not spent twice.
Although DigiCash was the first to introduce many of the ideas that would later serve as the framework for future cryptocurrencies, the company did not have much commercial success. Only one US bank implemented the currency. DigiCash filed for bankruptcy in 1998 and was eventually sold off for assets. Other electronic cash systems such as First Virtual Holdings and Cybercash were created around the same time and suffered a similar fate.
One of the most significant problems with the early electronic cash systems is that they relied on centralized organizations like financial institutions to partner in the process. Relying on banks also created a single point of failure for early digital currencies, meaning that if a bank was to go out of business then the digital currency that the bank partnered with would go down with it.
Early digital currencies also suffered from the problem of governments shutting them down overnight, rendering many early e-cash solutions useless. Government intervention ceased operations for several digital currencies such as E-Gold and GoldMoney over concerns that the criminal underworld was using the currencies to launder money and facilitate illegal transactions.
The problem of government regulation intensified following 9/11 as governments tried new ways to stop the transfer of funds to terrorist organizations. The perception that central authorities could suspend digital currencies simply by enacting new legislation gave the public a good reason to be reluctant in adopting them.
Nick Szabo, a cryptographer and computer scientist, was the next to introduce ideas around creating a decentralized digital currency with Bit Gold. Bit Gold never came to fruition, but it is essential in the history of digital currency as many of Szabo’s ideas would go on to become critical in the creation of cryptocurrencies. Bit Gold aimed to create a trustless transaction model tied to gold. The US Federal Reserve’s central bank broke the standard of having the money supply of US dollars tied to gold in 1971.
Bit Gold was the first digital currency to implement a proof-of-work (PoW) consensus algorithm. Using proof-of-work, cryptographic puzzles are solved using computational power. Each puzzle solution is broadcast on a peer-to-peer network. A cryptographic hash is created to link the solution of each puzzle to the next puzzle. In this model, all the users on the network need to agree on the previous puzzle’s answer before a new puzzle is generated. This method of consensus would be used to secure groups of transactions that would all be linked together using cryptographically hashed solutions.
Unlike Bitcoin, Szabo was unable to solve what is known as the double-spending problem. An example of the double-spending problem is spending $100 on goods and services and then using the exact same $100 to make additional purchases at another point in the future. Szabo wanted to mimic the characteristics of gold (which has intrinsic economic value) and to prevent fraud or mismanagement by centralized third parties. Up until the creation of blockchain and cryptocurrencies, centralized organizations were solely responsible for maintaining and updating the account balances used in financial transactions.
British cryptographer Adam Back created the digital currency Hashcash in 1997. Back wanted to introduce a system that could prevent spammed emails by restricting the amount of internet resources each user can spend per email.
Back’s solution to spam email required that users spend a small amount of computing power to solve a puzzle before they would be able to send emails. For regular emails, the amount of computational power to solve each puzzle would be tiny, and it would only delay an email by a few seconds.
However, someone trying to send spam email would be prevented from doing so by making it almost impossible for them to have the computational resources to send out thousands of emails all at once. It would also prevent spammed email by requiring that the senders pay for the electricity costs necessary to use a vast amount of computing power. Hashcash was referenced in Satoshi Nakamoto’s Bitcoin white paper. According to Nakamoto, a proof-of-work system similar to Hashcash would be needed in the blockchain that would be used to create Bitcoin.
Computer engineer Wei Dai proposed another digital currency with the paper, "B-money, an anonymous, distributed electronic cash system" in 1998. The first protocol outlined in the article proposed using Hashcash’s proof-of-work consensus algorithm to create money. In the proposed system, transactions would be broadcast to everyone on the network to keep a balance of all the money in each account.
In the second protocol, only a small subset of the network’s participants would be used to keep the balance in each account. He set out to create a punishment and reward system by having each server deposit a certain amount of funds in an account to be used as fines or rewards for proof of misconduct.
To fully understand the development of digital currency, one must understand the story of the Cypherpunks. Cypherpunk is the name given to an activist that advocates for social and political change by using privacy-enhancing technologies such as cryptography.
A small group of cryptographers met in the San Francisco Bay area and adopted the name Cypherpunks in 1992. The Cypherpunks mailing list was created later that year, acting as a forum for discussing computer science, cryptography, math, politics, and philosophy.
The core Cypherpunk philosophy is that individuals should have the power to reveal their identity only when they choose to reveal it, and that neither governments or corporations can be entirely responsible for protecting that right.
Satoshi Nakamoto cited several Cypherpunks in his original article. He first announced his white paper and the genesis block creation for Bitcoin through the Cypherpunk mailing list. Many of the early Cypherpunks went on to become developers for Bitcoin.
With the creation of Bitcoin in 2009, Nakamoto was able to solve many of the problems that plagued his predecessors. By using a decentralized peer-to-peer network of computers that continually updates and maintains a public ledger (known as the blockchain) the problem of double spending is eliminated.
Nakamoto explained this process in his 2008 white paper by stating, “Digital signatures provide part of the solution, but the main benefits are lost if a trusted party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work”.
Said more simply, for someone to double-spend funds they would have to deceive the entire network into thinking that it was a legitimate transaction. New coins cannot be faked or copied and every transaction in the history of a cryptocurrency can be found on the blockchain. Making it nearly impossible to spend the same money twice.
Nakamoto referenced the ideas first proposed by Szabo, Back and Dai in his white paper. The proof-of-work consensus algorithm outlined by the previous three authors defined the process over the creation of new Bitcoins.
Bitcoins are issued to users on the system who help process transactions on the network. This is known as Bitcoin mining. Releasing a known and fixed number of coins over a given period of time creates an environment of scarcity for the currency, leading to the coins having value. This removes the need for Bitcoin to be tied to some other asset that has an intrinsic economic value such as gold.
Nakamoto also found a solution to the problem DigiCash experienced of needing to rely on financial institutions in the transaction process by having a decentralized network that holds all of the transaction information in a public blockchain.
With Bitcoin, there is no central authority or financial intermediary to regulate or attack. Solving the problem of other early digital currencies such as E-Gold and Gold Money that were essentially shut down overnight by new government regulations. No government or third-party can censor or shutdown a cryptocurrency like Bitcoin. Bitcoin does not have a single point of failure.
To summarize, Bitcoin is not the world’s first digital currency. Attempts to create a digital currency goes back to the 1980s with key players such as David Chaum, Nick Szabo, Adam Back, Wei Dai and the original Cypherpunks all playing significant roles. However, many of the earlier attempts at creating digital currencies informed and inspired Satoshi Nakamoto in the creation of blockchain and Bitcoin.

Harmony Staking System

Staking-based Sharding Validator Registration Sybil attack prevention is a key security consideration in public blockchains. Bitcoin and Ethereum require the miners to compute a cryptographic puzzle (PoW) before they can propose a block. Similarly, sharding-based blockchains like Zilliqa or Quarkchain also use PoW to prevent Sybil attacks. Harmony adopts a different approach with proof-of-stake (PoS) as the validator registration or Sybil attack prevention mechanism. In order to become a Harmony validator, prospective participants (or stakers) have to stake a certain amount of tokens to be eligible. The number of tokens staked will determine the number of voting shares assigned to the validator. Each voting share corresponds to one vote in the BFT consensus.
A voting share is a virtual ticket that allows a validator to cast one vote in the consensus. Validators can acquire voting shares by staking tokens. The amount of tokens required for a voting share is algorithmically adjusted. At the beginning of each epoch, new validators’ voting shares will be randomly assigned to shards. The new validators join the shard(s) where their voting shares get assigned. As discussed in §2, the consensus in a shard is reached by validators who collectively possess at least 2 f + 1 voting shares to sign the block.
To guarantee the security of a single shard, the amount of voting shares by malicious validators needs to be kept below 31 of all the voting shares in that shard. This is required due to the nature of BFT consensus. Harmony’s adaptive thresholded PoS guarantees the above security requirement by adaptively adjusting the price of a voting share and assigning individual voting shares to shards rather than individual validators.

How much faster is Stellar compared to other blockchains?

How much faster is Stellar compared to other blockchains?
If you’ve just started using XLMwallet and XLM in general, you might be shocked by the speed. After Bitcoin and Ethereum it’s like getting out of a horse-drawn cart and getting into a Boeing. But what makes Stellar so lightning-fast?
As you might now, the Bitcoin blockchain only processes about 7 transactions per second. Since you need quite a few confirmations for a transaction to go through, you’ll have to wait about an hour to get access to your money. Ethereum is a tad better: it processes 15–20 operations per second, so you’ll just need to wait a few minutes. But it’s still far too long compared to Visa and Mastercard, which have a speed of thousands tps.
Stellar is one of the very few blockchains that can compete with global payment systems. On standard equipment, it delivers about 1500 tps. For comparison: Visa processes about 2000 tps under normal conditions. When running on top-grade equipment, Stellar easily reaches 4000 tps. That’s incredibly fast for a blockchain.
Why can Stellar do what Bitcoin and Ethereum cannot? The answer is both very simple and very complex. In a few words, Stellar doesn’t rely on mining.
In both Bitcoin and Ethereum networks, miners add new blocks to the chain by solving cryptographic puzzles. All miners are working on the same puzzle at the same time. The puzzles are designed in such a way that finding a solution is hard, but once it’s found, it’s very easy to verify. Whoever is the first to solve the puzzle gets the block reward and adds a new block to the chain. This consensus protocol is known as Proof of Work.
Now, the number of confirmations is the number of blocks that were added to the chain after the block that contains a certain transactions. So for example, if your payment makes part of block number 100, and the required number of confirmations is 3, it means that your transaction will be fully processed and confirmed once block 103 is added to the blockchain. This is for security reasons: it reduces the risks of so-called double-spend attacks.
Unfortunately, it also slows the system down. If the average block time is 10 minutes (as it is on Bitcoin) and you need 3 confirmations (3 blocks), then you’re looking at half an hour at least. This mechanism makes the system safe, but it also prevents scaling.
The solution planned for Ethereum is to switch to Proof-of-Stake — another consensus protocol, without any puzzles. It can theoretically increase the processing speed to thousands of tps — but it’s still years away.
Stellar, however, is already there. It managed to get so far ahead because it went on a completely different path. There are no puzzles to solve, and no new lumens are generated. All of the hundred billion lumens were generated at once, in the very beginning. There is no mining at all. The consensus protocol is neither Proof of Stake nor Proof of Work. It’s called SCP (Stellar Consensus Protocol), and it’s based on something called a Federated Byzantine Agreement.
The SCP is not easy to explain, but in our next posts we’ll try to do that. For now, remember that when you use XLMwallet, you get access to the fastest and cheapest blockchain on the market — Stellar. See our site https://xlmwallet.co/ for more info.

What are Cryptocurrency Miners? How does Cryptocurrency Mining work?

What are Miners?

Cryptocurrencies and fiat currencies differ in the way that new coins/cash are generated and issued in their respective ecosystems. Fiat currencies are printed by government-sponsored mints in response to a state authority’s direct orders, while cryptocurrencies are issued by a blockchain network according to a set of predetermined algorithms. Blockchain networks that create tokens based on Proof of Work schemes require mining, a complicated process. In brief, participants use hardware to run algorithms on specific software to verify transactions on the blockchain, add those transactions to the public ledger and in exchange receive the reward of a newly-created coin. We will break the mining process down step by step below.

Cryptocurrency Mining Step by Step

  1. When a transaction is made over a blockchain (for instance, when one user sends a few coins to another user’s address), the transaction information must be recorded and is thus put on a block.
  2. This block needs security and encryption, and is up for grabs by all of the contributing miners on the network.
  3. To encrypt this block, miners must solve a cryptographic puzzle through a guess-and-check method in order to find the proper cryptographic hash for the block. Miners typically need large rigs of reliable, application-specific hardware to actually have a decent chance at being the first to verify and secure the block.
  4. Once a miner secures the block, the block is then added to the blockchain and must be verified by other nodes (computers) on the network in a process known as consensus.
  5. If a miner successfully verifies and secures the block, the miner is rewarded with a newly-created coin. This process of reward for work is called Proof of Work.

Cryptocurrency Mining and Profitability Concerns

Mining is called mining because it is a process in which volunteers contribute a great deal of effort in the hopes of receiving ‘a gold coin.’ It makes sense that most miners who wish to contribute to blockchains are in the game for a profit. The biggest concern for miners has always been the ever-increasing difficulty of the computational puzzles involved in securing the blocks. That’s right; as more puzzles are solved, the difficulty of the next puzzle increases greatly, sometimes even exponentially.
To make mining profitable, organizations have invested a great deal into research and development of more advanced solution algorithms and more efficient pieces of hardware. Some organizations have gone so far as to move their mining rigs to rural dams and countries where electric power supply is less expensive. In terms of hardware, some organizations with significant capital have made investments in ASICs, or Application Specific Integrated Circuits. This class of hardware is designed to complete very specific tasks, namely mining. In the early days of Bitcoin mining, miners could make profits off of just using a home computer central processing unit, or CPU. The issue with CPUs is that they are designed to juggle multiple computational tasks simultaneously, like running multiple programs on your computer screen at once. Unfortunately for the hobbyists, using conventional CPU’s is simply not profitable in most blockchains anymore.
It’s important to note is that most coins on most successful blockchains that use Proof of Work schemes will become profitable for mining only if individuals are willing to make large investments in hardware rigs, electric power supplies, or some combination of the two. Corporations are already aware of this fact, entering the mining arena with full force in order to take large cuts of the mining profits. Likewise, smaller organizations and individuals are currently struggling to compete in the space. The big issue here is the increasing centralization of mining; if the process for coin creation becomes controlled entirely by a handful of centralized powers, then how will the blockchain continue to bring decentralized solutions to users?

Addressing Cryptocurrency Mining Concerns

In response to these concerns with mining centralization, newer blockchains and altcoins have been adopting more complex mining algorithms and proof schemes to limit the influences of ASICs and large corporations. Some investors in blockchain technology who saw great success in the early days of mining have created mining funds to support small-scale, international miners. This is an effort to decentralize the mining process for blockchains that require Proof of Work. And while Proof of Work schemes favor the biggest hardware rigs, new schemes like Proof of Stake and Proof of Burn have made an appearance. Newer schemes reward miners based on a different set of factors.
Another big concern that has been well-addressed by Ethereum, Ethos and other gas-powered blockchain systems is wasted mining efforts / mining inefficiency. For example, if many miners attempt a block at once and only one miner gets the block, or if the miners attempt an unsolvable, infinitely complex puzzle, miners are forced to waste an abundant amount of computational power. The solution? Gas powered blockchain systems require developers to attach gas to a transaction, and that gas will supply the transaction’s computational power until either the transaction is completely validated or until the gas runs out. This creates a safer way for miners to contribute their efforts towards solving new blocks. Without the risk of wasting unnecessary computational energy, miners are guaranteed a quicker and more efficient maintenance of the blockchain.

Takeaway

Blockchain mining has become one of the most interesting and controversial topics in the blockchain community. However, mining is just one component of blockchain analysis, through the Ethos Universal Wallet and the Ethos Knowledge Base we seek to provide those interested in blockchain additional metrics and information. Ultimately, the state of mining has a great effect on each coin’s decentralized state, value and reliability. It is critically important to the team at Ethos to understand how fair and accessible mining is in different blockchain networks. We therefore document and analyze major players in the industry while taking into account these components. And as always, we at Ethos encourage our readers to educate themselves (using our supplemental resources or not) on how crypto really works, both at the surface level and behind the scenes. We want our readers and users to make responsible, well-educated decisions as we step forward into the new economy.

My growing collection of info about NEO

It can be very time consuming to keep up to date on a single blockchain project let alone multiple ones. If you just heard about NEO a few weeks ago it would be impossible catch up on past occurrences due to high volume of Reddit posts and articles made on the project. I’m going to try and simplify the past, present and future as much as I can into one well thought-out post. I hope I can be helpful to anyone who has been investigating like myself. I will include sources with all of my research.

Key notes from the White Paper http://docs.neo.org/en-us/
Digital Assets
Digital assets are programmable assets that exist in the form of electronic data. With blockchain technology, the digitization of assets can be decentralized, trustful, traceable, highly transparent, and free of intermediaries. On the NEO blockchain, users are able to register, trade, and circulate multiple types of assets. Proving the connection between digital and physical assets is possible through digital identity. Assets registered through a validated digital identity are protected by law.
Digital Identity
Digital identity refers to the identity information of individuals, organizations, and other entities that exist in electronic form. The more mature digital identity system is based on the PKI (Public Key Infrastructure) X.509 standard. In NEO, we will implement a set of X.509 compatible digital identity standards. This set of digital identity standards, in addition to compatible X.509 level certificate issuance model, will also support Web Of Trust point-to-point certificate issuance model. Our verification of identity when issuing or using digital identities includes the use of facial features, fingerprint, voice, SMS and other multi-factor authentication methods.
Smart Contracts
The NeoContract smart contract system is the biggest feature of the seamless integration of the existing developer ecosystem. Developers do not need to learn a new programming language but use C#, Java and other mainstream programming languages in their familiar IDE environments (Visual Studio, Eclipse, etc.) for smart contract development, debugging and compilation. NEO's Universal Lightweight Virtual Machine, NeoVM, has the advantages of high certainty, high concurrency, and high scalability. The NeoContract smart contract system will allow millions of developers around the world to quickly carry out the development of smart contracts.
Economic Model
NEO has two native tokens, NEOand NeoGas NEO represents the right to manage the network. Management rights include voting for bookkeeping, NEO network parameter changes, and so on. The minimum unit of NEO is 1 and tokens cannot be subdivided. GAS is the fuel token for the realization of NEO network resource control. The NEO network charges for the operation and storage of tokens and smart contracts, thereby creating economic incentives for bookkeepers and preventing the abuse of resources. The minimum unit of GAS is 0.00000001.
Distribution Mechanism
NEO's 100 million tokens are divided into two portions. The first portion is 50 million tokens distributed proportionally to supporters of NEO during the crowdfunding. This portion has been distributed.
The second portion is 50 million NEO managed by the NEO Council to support NEO's long-term development, operation and maintenance and ecosystem. The NEO in this portion has a lockout period of 1 year and is unlocked only after October 16, 2017. This portion WILL NOT enter the exchanges and is only for long-term support of NEO projects. The plans for it are as below:
▪ 10 million tokens (10% total) will be used to motivate NEO developers and members of the NEO Council
▪ 10 million tokens (10% total) will be used to motivate developers in the NEO ecosystem
▪ 15 million tokens (15% total) will be used to cross-invest in other block-chain projects, which are owned by the NEO Council and are used only for NEO projects
▪ 15 million (15% total) will be retained as contingency
▪ The annual use of NEO in principle shall NOT exceed 15 million tokens
GAS distribution
GAS is generated with each new block. The initial total amount of GAS is zero. With the increasing rate of new block generation, the total limit of 100 million GAS will be achieved in about 22 years. The interval between each block is about 15-20 seconds, and 2 million blocks are generated in about one year. According to this release curve, 16% of the GAS will be created in the first year, 52% of the GAS will be created in the first four years, and 80% of the GAS will be created in the first 12 years. GAS will be distributed proportionally in accordance with the NEO holding ratio, recorded in the corresponding addresses. NEO holders can initiate a claim transaction at any time and claim these GAS tokens at their holding addresses.
Consensus mechanism: dBFT
The dBFT is called the Delegated Byzantine Fault Tolerant, a Byzantine fault-tolerant consensus mechanism that enables large-scale participation in consensus through proxy voting. The holder of the NEO token can, by voting, pick the bookkeeper it supports. The selected group of bookkeepers, through BFT algorithm, reach a consensus and generate new blocks. Voting in the NEO network continues in real time, rather than in accordance with a fixed term.
Cross-chain assets exchange agreement
NeoX has been extended on existing double-stranded atomic assets exchange protocols to allow multiple participants to exchange assets across different chains and to ensure that all steps in the entire transaction process succeed or fail together. In order to achieve this function, we need to use NeoContract function to create a contract account for each participant. If other blockchains are not compatible with NeoContract, they can be compatible with NeoX as long as they can provide simple smart contract functionality.
Cross-chain distributed transaction protocol
Cross-chain distributed transactions mean that multiple steps of a transaction are scattered across different blockchains and that the consistency of the entire transaction is ensured. This is an extension of cross-chain assets exchange, extending the behavior of assets exchange into arbitrary behavior. In layman's terms, NeoX makes it possible for cross-chain smart contracts where a smart contract can perform different parts on multiple chains, either succeeding or reverting as a whole. This gives excellent possibilities for cross-chain collaborations and we are exploring cross-chain smart contract application scenarios.
Distributed Storage Protocol: NeoFS
NeoFS is a distributed storage protocol that utilizes Distributed Hash Table technology. NeoFS indexes the data through file content (Hash) rather than file path (URI). Large files will be divided into fixed-size data blocks that are distributed and stored in many different nodes
Anti-quantum cryptography mechanism: NeoQS
The emergence of quantum computers poses a major challenge to RSA and ECC-based cryptographic mechanisms. Quantum computers can solve the large number of decomposition problems (which RSA relies on) and the elliptic curve discrete logarithm (which ECC relies on) in a very short time. NeoQS (Quantum Safe) is a lattice-based cryptographic mechanism. At present, quantum computers do not have the ability to quickly solve the Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP), which is considered to be the most reliable algorithm for resisting quantum computers.
Reasons for choosing dBFT over PoW and PoS:
With the phenomenal success of Bitcoin and its increasing mainstream adoption, the project’s unbounded appetite for energy grew accordingly. Today, the average Bitcoin transaction costs as much energy as powering 3.67 average American homes, which amounts to about 3000 times more than a comparable Credit Card settlement.
This mind boggling amount of energy is not, as it is commonly believed, being wasted. It is put to good use: securing the Bitcoin network and rendering attacks on it infeasible. However, the cost of this security mechanism and its implications for an increasingly warming and resource hungry planet led almost the entire crypto industry to the understanding that an alternative has to be found, at least if we’re interested in seeing blockchain technology gaining overwhelming mainstream adoption.
The most popular alternative to PoW, used by most alternative cryptocurrency systems, is called Proof-of-Stake, or PoS. PoS is highly promising in the sense that it doesn’t require blockchain nodes to perform arduous, and otherwise useless, cryptographic tasks in order to render potential attacks costly and infeasible. Hence, this algorithm cuts the power requirements of PoS blockchains down to sane and manageable amounts, allowing them to be more scalable without guzzling up the planet's energy reserves.
As the name suggests, instead of requiring proof of cryptographic work, PoS requires blockchain nodes to proof stake in the currency itself. This means that in order for a blockchain node to be eligible for a verification reward, the node has to hold a certain amount of currency in the wallet associated with it. This way, in order to execute an attack, a malevolent node would have to acquire the majority of the existing coin supply, rendering attacks not only costly but also meaningless, since the attackers would primarily harm themselves.
PoS, as well as PoW, simply cause the blockchain to fork into two alternative versions if for some reason consensus breaks. In fact, most blockchains fork most of the time, only to converge back to a single source of truth a short while afterwards.
By many crypto enthusiasts, this obvious bug is very often regarded as a feature, allowing several versions of the truth to survive and compete for public adoption until a resolution is generated. This sounds nice in theory, but if we want to see blockchain technology seriously disrupt and/or augment the financial sector, this ever lurking possibility of the blockchain splitting into two alternative versions cannot be tolerated.
Furthermore, even the fastest PoS blockchains out there can accomodate a few hundred transactions per second, compare that to Visa’s 56,000 tx/s and the need for an alternative becomes clear as day.
A blockchain securing global stock markets does not have the privilege to fork into two alternative versions and just sit and wait it out until the market (or what’s left of it) declares a winner. What belongs to whom should be engraved in an immutable record, functioning as a single source of truth with no glitches permitted.
After investigating and studying the crypto industry and blockchain technologies for several years, we came to the conclusion that the delegated Byzantine Fault Tolerance alternative (or dBFT) is best suited for such a system. It provides swift transaction verification times, de-incentivises most attack vectors and upholds a single blockchain version with no risk of forks or alternative blockchain records emerging - regardless of how much computing power, or coins an attacker possesses.
The term Byzantine Fault Tolerance (BFT) derives its name from the Byzantine Generals problem in Game Theory and Computer Science, describing the problematic nature of achieving consensus in a distributed system with suboptimal communication between agents which do not necessarily trust each other.
The BFT algorithm arranges the relationship between blockchain nodes in such a way that the network becomes as good as resilient to the Byzantine Generals problem, and allows the system to remain consensus even if some nodes bare malicious intentions or simply malfunction.
To achieve this, Antshare’s version of the delegated BFT (or dBFT) algorithm acknowledges two kinds of players in the blockchain space: professional node operators, called bookkeeping nodes, who run nodes as a source of income, and users who are interested in accessing blockchain advantages. Theoretically, this differentiation does not exist in PoW and most PoS environments, practically, however, most Bitcoin users do not operate miners, which are mostly located in specialized venues run by professionals. At Antshares we understand the importance of this naturally occurring division of labor and use it to provide better security for our blockchain platform.
Accordingly, block verification is achieved through a consensus game held between specialized bookkeeping nodes, which are appointed by ordinary nodes through a form of delegated voting process. In every verification round one of the bookkeeping nodes is pseudo-randomly appointed to broadcast its version of the blockchain to the rest of the network. If ⅔ of the remaining nodes agree with this version, consensus is secured and the blockchain marches on. If less than ⅔ of the network agrees, a different node is appointed to broadcast its version of the truth to the rest of the system, and so forth until consensus is established.
In this way, successful system attacks are almost impossible to execute unless the overwhelming majority of the network is interested in committing financial suicide. Additionally, the system is fork proof, and at every given moment only one version of the truth exists. Without complicated cryptographic puzzles to solve, nodes operate much faster and are able to compete with centralized transaction methods.

OnChain
It is important to note the technical difference between Onchain and NEO. Onchain is a private VC-backed company with over 40 employees. NEO is a public platform with different community-led groups contributing to this public project. There exists NEO council comprised of the original NEO creators, employees from Onchain, full time NEO council members and there is also the first Western based group called City of Zion. This confusion is likely the source of the rumour about Antshares and Alibaba having a connection. Onchain and NEO are separate entities who are intimately related via cross-chain communications and similar designs.
Onchain, a Shanghai-based blockchain R&D company, first started developing Antshares in February of 2014 which will eventually become the foundation of DNA. Onchain was founded by CEO Da HongFei and CTO Erik Zhang in response to the attention from private companies garnered by the development of Antshares, China’s first public blockchain. In contrast to the weeks-old start-ups launching ICOs that is happening currently in the blockchain world, it took them 22 long months of R&D to even begin providing services to their first customers. Finally, in April 2016, the first whitepaper on consensus protocol from China was born — the dBFT (delegated Byzantine Fault Tolerance) protocol.
2016 was a busy year for Onchain and they really picked up the pace that year. Other than continuing the development of Antshares, brushing shoulders with Fortune 500 companies, Onchain became the first Chinese blockchain company to join Hyperledger — an open source blockchain project started by the Linux Foundation specifically focusing on the development of private and consortium chains for businesses. It is here where the Da HongFei and Erik Zhang, entered the hyperbolic time chamber that is now known as Fabric, a platform by Hyperledger for distributed ledger solutions, and has consequently helped them to develop many aspects underpinning the design of DNA.
In June of 2016, during the first of many future partnerships with Microsoft China, Onchain founded Legal Chain specifically targeting the inadequacies of the digital applications within the legal system. In 2005, (Digital Signature Act) was passed into national law which permitted an effective digital signatures to gain the same legal rights as a real signature.
In company with Microsoft China, they are also aiming to integrate the technology with Microsoft’s face and voice recognition API function to kick start this digital revolution within the legal system. At the same time, a partnership was formed with FaDaDa, a third-party platform for electronic contracts that has processed over 27 million contracts to date, to provide secure evidence storage with DNA. If that’s not enough, they were also voted as KPMG’s top 50 Fintech Company in China and established a relationship with the Japanese Ministry of Economy, Trade and Industry which led to the recent tour to Japan. Finally, at the end of 2016 they announced a partnership with Alibaba to provide attested email service for Ali Cloud with Legal Chain where it provides a proof-of-existence for a blockchain-powered email evidence repository for enterprise-level use.
Fosun Group, China’s largest private conglomerate, have recently invested into Onchain in order to apply DNA across all of its businesses. Currently, Fosun International has a market cap of 102.98 billion dollars on the Hong Kong Stock Exchange and that is only its international branch.
The role of Onchain so far is reminiscent of Ethereum’s EEA in addition to a stronger emphasis of governmental cooperation. Onchain has identified the shortcomings of present laser focus of hype on public platforms such as NEO and Ethereum and addressing that with DNA. DNA envisions a future where a network of assorted, specifically designed blockchains serving private enterprises, consortiums, government and the public communicating with each other forming an interconnected blockchain network.
This is the goal of DNA — infiltrating every little inefficient niche that had no better alternatives before the invention of blockchain. What is especially critical to remember during this explosive time of hype driven partly by the obscene degree of greed is that not every little niche that blockchain can fill will be holding its own little ICO for you to “go to the moon on your rocket powered lambos”. Some of those efficiencies gained will simply be consumed by companies privately or by public systems such as the legal system.

Networks proves itself with the first ICO
ICOs, on other platforms such as Ethereum, often resulted in a sluggish network and transaction delays. While NEO’s dBFT consensus algorithm is designed to achieve consensus with higher efficency and greater network throughputt, no amount of theoretical calculations can simulate the reality of real-life conditions.
--Key Observations--
Smart Contract Invocations:
A total of 13,966 smart contracts invocations were executed on the NEO network over this time period, of which, nearly all called the RPX smart contract method mintTokens. A total of 543,348,500 RPX tokens were successfully minted and transferred to user accounts, totalling 10,097 smart contract executions.
Refunded Invocations:
A total of 4182 refund events were triggered by the smart contract method mintTokens. (Note: RPX has stated that these refunds will be processed within the next two weeks.)
Crowdsale statistics:
A successful mintTokens execution used around 1043 VM operations, while an execution that resulted in a refund used 809 VM operations. Within the hour and six minutes that the token sale was active, a total of 12,296,409 VM operations were executed. A total of 9,575 unique addresses participated in the RPX ICO. Half of these, approximately 4,800 unique addresses, participated through CoZ’s Neon wallet. The top 3 blocks with the most transactions were block 1445025 (3,242 transactions), block 1444902 (2,951 transactions), and block 1444903 (1609 transactions).
Final Thoughts
At the moment, the consensus nodes for the NEO network are operated by the NEO Council in China. By Q1 2018, NEO Council aims to control less than two-thirds of the consensus nodes.
We are pleased to note that the NEO network continuted to operate efficiently with minimal network impact, even under extreme network events. Block generation time initially slowed down to 3 minutes to process the largest block, but quickly recovered to approximately 25 seconds. Throughout the entire RPX ICO, consensus nodes were able to achieve consensus and propagate new block transactions to the rest of the network. In closing, while we consider this performance to be excellent, NEO Council and City of Zion areworking closely together on upgrades, that will increase the throughputs of the NEO network.
Hyperledger

Da Hongfei quotes
"There is no direct cooperation between Alibaba and NEO/Onchain, other than their mailbox service is using Law Chain to provide attested email service. In terms of Microsoft, yes we have cooperation with Microsoft China because NEO is built with C# and .NET Core, and NeoContract is the first in the world to support writing smart contract with C#"

"We have pretty good communication with government, with regulators. They don't have any negative impression with NEO and they like our technology and the way we deal with things. Regulation is not an issue for us"
https://www.youtube.com/watch?v=qpUdTIQdjVE&feature=youtu.be&t=1m16s
“Before they started cleaning up the market, I was asked for information and suggestions” “I do not expect the government to call me in the short-term and say, ‘Let’s use NEO as the blockchain technology infrastructure of China.’ But in the medium term? Why not? I think it’s possible.”
