Bitcoin theory
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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 concept of bitcoin was founded by Nakamoto
On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank
In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the InternetThe price of a bitcoin soared from more than $20000 to $40000. This can not help but arouse my research interest, or simply understand what bitcoin is, what its mechanism looks like, and uncover its mystery. Therefore, after a simple search of some information and some understanding of the special currency, I sorted out the information on hand< (3) purpose: decentralize, rece risk
all servers in the distributed network can store and process data, and each server has equal status, which can store more data and has higher security<
this is the general content of popular science. If you want to know more about it, you can take a look at Nakamoto's paper and the official popular science video below
bitcoin, to some extent, is the proct of the development of today's social economy and network technology to a certain stage. Because it is accepted by everyone and endowed with a certain value, bitcoin circulates around the world
the circulation of bitcoin is mainly through the bitcoin trading platform; Although the domestic bitcoin transaction is prohibited, but in other foreign countries, even as the role of currency, can be used for the payment of goods
similarly, some investors believe that bitcoin has great development space; As a result, a lot of people hold bitcoin, or store it in bitcoin wallets, such as coin packets, or use it in trading platforms to get more revenue
bitcoin is becoming more and more important, so in some cases, it plays the role of currency in the world.

Bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security
blockchain is a technology, and the financial procts grafted on it are digital currency, such as bitcoin, lightcoin, Ethereum, etc. To be polite, blockchain oil futures trading should be a gimmick. To be polite, it's a liar.
In short, the principle of brick Arbitrage: buy low and sell high, buy money from the place with low price and sell it at the place with high price, that is to earn the price difference of different platforms
but there are three risks in moving bricks:
A. time difference of currency transfer: it takes a certain waiting time to pick up or deposit the currency, so it may miss the best trading time
B. currency price fluctuation: if the currency price fluctuation is relatively large and the process of moving bricks has not been completed, the price difference has disappeared
C. platform problems: some trading platforms may shut down services from time to time, or even run away
principle: carry out brick arbitrage on two platforms at the same time to avoid the risk of "time difference of currency transfer" and "currency price fluctuation"
before moving bricks: the brick moving platform must support the same currency transaction, and the brick moving platforms must be able to transfer currency to each other
Step 1: price difference calculation. There are handling charges for currency trading and currency transfer, so you have to calculate the cost according to your own funds. Only when the price difference reaches how much can it be profitable to move bricks
Step 2: simultaneous operation. Buy BTC on the low price platform and sell BTC on the high price platform. At this time, the number of BTC holdings remains unchanged and the number of usdt increases You need to pay attention to transaction fees.)
Step 3: balance funds. It is difficult to predict which platform has a lower price and which has a higher price e to the price difference. Therefore, the two platforms that move bricks need to prepare usdt and BTC. When the price difference appears, it is convenient to move bricks There are also handling charges for cross platform currency transfer.)
the above is the principle and steps of risk-free arbitrage using BTC and usdt. It also has a big name: quantitative hedging. The fundamental purpose is to earn usdt, not BTC
You can take a closer look at this: Web linkselliptic curve digital signature algorithm is mainly used in the generation process of bitcoin public key and private key, which is the cornerstone of bitcoin system. SHA-256 hash algorithm is mainly used in the workload proof mechanism of bitcoin
the principle of bitcoin generation is the special solution generated by complex operation, and mining is the process of finding the special solution. However, the total number of bitcoin is only 21 million, and with the continuous mining of bitcoin, the more difficult it will be to proce bitcoin, and the cost of acquiring bitcoin may be higher than the price of bitcoin itself
the bitcoin block consists of a block header and the transaction list contained in the block. The size of the block header is 80 bytes, which is composed of 4-byte version number, 32 byte hash value of the previous block, 32 byte Merkle root hash, 4-byte timestamp (current time), 4-byte current difficulty value and 4-byte random number. A block header with a fixed length of 80 bytes is the input string used to prove the workload of bitcoin. Constantly change the random number in the block header, that is, the value of nonce, and do double sha256 operation on the block header after each change, and compare the result value with the target value of the current network. If it is less than the target value, the problem is solved successfully, and the workload is proved to be complete
the essence of bitcoin is actually the unique solution of a set of equations generated by a bunch of complex algorithms. Bitcoin is the first distributed virtual currency in the world, which has no specific distribution center. The network of bitcoin is composed of all users, because there is no center to ensure the security of data.
