BTC logic
It was officially born on January 3, 2009
since 2015, the future of bitcoin has become more and more uncertain. On the one hand, bitcoin fell as much as 55.55% against RMB last year; In 2015, bitcoin fell by more than 30% against the RMB in the first half of January alone
bitcoin's "falling" reflects the "self-healing" of its value after "fanaticism" to a certain extent. According to statistics, in 2013, bitcoin rose from 1 ∶ 13.59 to 1 ∶ 731, with an annual increase of 5300%. This speculative driven inflation has affected the virtual currency property on which bitcoin relies
on the one hand, no country has defined it as a legal currency. On the other hand, in 2014, the US dollar rose significantly, and the prices of oil and bulk commodities fell correspondingly. The price trend of bitcoin is the same as that of the latter, becoming part of the asset allocation of some speculators, which highlights that its asset attribute is far greater than the monetary attribute
extended data
Security and credit risk have also become the reasons for the decline of investor confidence. Mt. GOx, once the world's largest bitcoin exchange, claimed in March last year that it had lost all its assets e to hacker attacks. Recently, it was revealed that its lost bitcoin was probably e to internal system manipulation
the regulatory environment of bitcoin is not optimistic, and Russia, Thailand and other countries have begun to implement strict control on it. In addition, the global stock market performed well last year, resulting in the diversion of bitcoin investment funds, and the crazy "mining" activities also rapidly increased the supply of bitcoin, which may lead to a trend of oversupply in the short term, leading to a sharp drop in the price of bitcoin
The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
The earliest is a kind of network virtual currency. 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. In 2013, the U.S. government recognized the legal status of bitcoin, making the price of bitcoin soar
< H2 > extended information:bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
many websites for technology players have begun to accept bitcoin transactions. Websites such as mtgox and btcchina, as well as some Taobao stores, can even accept services such as bitcoin exchange for us dollars and euro. There is no doubt that bitcoin has become a real currency in circulation, rather than a virtual currency like Tencent Q coin
The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes
according to this algorithm, a block contains about 4194.3 transactions
the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven
What are the consequences The bifurcations of
bitcoin are divided into hard bifurcations and soft bifurcations
hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes
the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains
What is soft bifurcationsoft bifurcation means that when the data structure of bitcoin transaction changes,
UN upgraded nodes can verify the blocks proced by upgraded nodes,
and upgraded nodes can also verify the blocks proced by UN upgraded nodes
The 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 is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end
it's all investment logic, and then most of it is speculative psychology
the game between makers and retail investors
