Bitcoin throughput
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is data parallelism (DLP)
3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.
1: value is the so-called currency born from the early decentralized blockchain Technology (in fact, the capital owns the centralized computing power, and the capital owns the centralized currency quantity, which may not be ideal here). At that time, people had certain expectations and beliefs. The decentralized low trust cost world chase was a good future imagination, which made most people recognize its value (of course, it also caused negative use value, which could not be controlled and regulated by the government, and provided a lot of extra convenience)
of course, some attributes of digital currency can be used for reference, Now countries are also in the trend of legal digital currency. Due to certain technical reasons, BTC may eventually disappear, or it is difficult to achieve the vision of believers. If there is no better change of technology, the limitation of technology will be phased out with the current development of science and technology
2: of course, the price is basically determined by market transactions. BTC is used by a lot of capital, and more value may be used as financial value Another common perception of price is that the quantity is limited and the output is getting slower and slower. With the increase of the use area, the scarcity increases the price, and the story of halving the price is also a good help for capitalists)
because it is a minority, there is no regulation, so the power of capital has a great impact on the price. The good effect of getting rich can attract more and more people to come into the market. The exchanges of various capital institutions have solved the problems of business instry, gained some additional operating income, and created instries (such as basic financial derivatives and more)
including this year's events, with the epidemic situation and the situation in the United States, new financial derivatives are manufactured by joint institutions. In the secondary market, a new circular wealth story is born. This mode is still relatively solid, with stable prices and rising prices. Of course, the final digester is the ordinary people
at the same time, the characteristics of BTC also lead to a part of human allocation of hedging assets
and so on, the price of BTC is proced under the game
personal final conclusion (for reference only): bitcoin is more of a kind of financial value, its use value is still limited at present, and it is also very difficult to promote in the future. If the technology does not evolve, it will still be small. Of course, the game of the world government is also a certain resistance
the current price is based on the financial game of institutions, and it is stable to a certain extent. The premise is that if there is no new large number of people participating in the game, the current rising trend will slow down, and the gray scale and institutions are also expanding the playing methods of other digital currencies (after all, the number of BTCs targeted by GBTC has accounted for more of the total BTCs - physical contribution plus less cash contribution), But there may still be a rise, but when it will be the top depends on the results of various games (I think there are several points: 1. How long can the game between the trading frequency and holding amount of BTC or other currencies in the primary market last, and when people's purchase and consumption will reach a limit. It can't be bought and sold all the time, there is a limit when what the 2. gradation and what the BTC of the GBTC corresponds to is the two level market digestion of the market, when it will be indigestion is also a game... Etc.)
BTC has bubble, and the financial game of capital is full of bubbles. Of course, this is the opportunity to get rich easily.
but the risk is very high, which is not suitable for the public. It can only be said that it depends on fortune and opportunity
BTC has big moves with every financial trend game
investment should be cautious.
Bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulationthe decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
This state should be normal for bitcoin. Bitcoin fell again, falling nearly 30% in a month. Over the same period, gold, a traditional safe haven asset, has strengthened significantly, up nearly 10% at a time. Therefore, if it is also defined as a safe haven asset, why did bitcoin and gold go out of completely different trends in the context of the collapse of the global stock market and the collapse of the crude oil market? In fact, the emergence of digital currency including bitcoin is driven by market demand. Since the financial crisis of the United States in 2008, many elites around the world have been looking for a kind of currency that is not only like gold but also not affected by sovereign credit, but also as convenient as US dollar
Digital currency similar to bitcoin has met some needs 
from a historical point of view, no matter who tries to prevent the improvement and development of currency as a tool, it will eventually fail and lose its competitive advantage . Of course, what we have to face at this stage is the sovereign nature of digital currency, because China's main body can provide more convenient services based on digital currency, which is impossible for bitcoin and so on. The current bitcoin throughput and operating costs, the difficulty of storage management and the inability of various ecosystems to provide more convenient transactions require more powerful technical improvements, which are difficult to achieve and beyond the limitations of the times
the working principle of lightning network is to create an interweaved network composed of two payment channels. Basically, it's a trade between two people. However, by creating a network in which all channels are interconnected, you can route payments through multiple channels. If you want to send payment to anyone in the network, you can credit the account directly connected with yourself (deposit money to the account) in your Lightning network channel, and then the account can credit the account connected with yourself (the amount is the same, so there is no actual change in value). This process continues, Until you pass it on to the participant you actually want to trade, he will receive the money
therefore, technically, you are only trading with an account directly associated with the payment channel where your funds were originally sent. So, every routing connection between you and the ultimate payee is made up of two participants who simply trade with each other, each of whom accounts for each other - a series of double entry paths. Lightning network is a network composed of double entry accounting channels of two participants, so there is no bottleneck in transaction throughput.
