Bitcoin diamond has split time
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 InternetIn September 2017, the central bank and other seven departments jointly issued the "notice on preventing the financing risk of token issuance", which defined ICO (initial coin offerings) as unauthorized and illegal public financing, suspected of illegal selling token bills, illegal issuing securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities
in 2017, ICO became very popular relying on the concepts of "digital currency", "blockchain" and "smart contract". However, only by publishing a "white paper" through a few people's team, and even some can start financing activities without a white paper, this operation mode has laid great risks for investors, and the outside world has always disputed the legitimacy of ICO. In September last year, the central bank and other seven departments gave a clear definition of ICO and stopped all kinds of token financing activities. Seven departments said in the announcement that token issuance financing is essentially an illegal public financing behavior without approval, and is suspected of illegal sale of token tickets, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal and criminal activities
However, after the ban of ICO, a new way of playing the coin circle, IFO, has sprung up. The so-called IFO refers to the branching currency issuance based on mainstream currencies such as bitcoin and Ethereum. On the basis of the original blockchain of these mainstream currencies, another chain is split according to different rules to generate new digital currency. People who hold mainstream currencies can get new currency after bifurcating in the process of IFO, and IFO has become a new means of virtual currency financingon August 1, 2017, the birth of BCH marked the first generation of bifurcated coin in the coin circle. The size of bitcoin block is only 1m, and the smaller the block is, the smaller the capacity is, the slower the bitcoin transaction will be. In order to solve the problem of bitcoin block congestion, BCH blockchain successfully separated from the main chain in block 478559, resulting in a new cryptocurrency. The default block size is 8m, which can also realize the dynamic adjustment of block capacity. At the same time, people who used to hold bitcoin can get BCH for free at a ratio of 1:1
since its birth, there have been different opinions about whether BCH is a new branch of bitcoin or another kind of "counterfeit currency". However, after several ups and downs, the price of BCH began to develop steadily. As of 20:30 p.m. on February 26, the price of BCH reached 8058.8cny, and that of BTC was 67558.69cny, according to the data of fire coin
following the success of BCH bifurcation, more and more new virtual currencies have been proced through IFO, such as BTG (bitcoin gold), BCD (bitcoin diamond), SBTC (super bitcoin), etc. Chen Yunfeng believes that according to the explanation of the technical level, part of the forked currency is the upgrading or improvement of the original technology. If it is a forked currency in this sense, it is difficult to say that it has no value. Moreover, when the regulatory level repeatedly prompts the investment risk of virtual currency, the investment value should be judged by the investors themselves
Shi Qingwei, the founder of sharing finance, said that IFO is a new way to play in the past two months, and most projects generated by IFO have no investment value. Some IFO issuers believe that they are not raising funds through ICO, but a fork of mainstream currencies such as bitcoin and Ethereum, which have a large number of users. After users get the forked coins, they usually ask to join the transaction, and then the issuer of IFO will get a huge profit because of the number of forked coins g in advance. He further said that most of the bifurcated currencies proced by IFOS have no investment value and even higher investment risk than ICOS"pre dig" fork currency or there is a risk of fraud
so, how does IFO make money According to the daily economic news, miners develop bifurcated coins in bitcoin blocks through technical means, and then distribute the developed bifurcated coins to bitcoin holders in proportion, and gain value in the transaction and circulation. Some of them will also be traded and circulated through the digital asset exchange. It is worth noting that most of the forked coins will be "pre g" before they are officially released. The pre g forked coins are equivalent to those obtained free of charge, so the founders of the forked coins can easily make profits. In the market, some people think that IFO in the name of "pre digging" is actually a more naked game of token issuance
on November 15, 2017, the domestic well-known super bitcoin team announced that it will implement the bifurcation at the 498888 height of bitcoin blockchain on December 17, and start the technical test of zero knowledge proof and intelligent contract supporting Turing complete, and expand its block to 8MB. It will also launch the intelligent contract in early March 2018 to increase the scalability of BTC Zero knowledge proof will be launched by the end of May 2018, and dynamic checkpoints will be removed by the end of November 2018 to realize fully decentralized mining. If the split is successful, a new split coin, SBTC, will be proced. The original bitcoin holders will give it away one by one, with a total amount of 21.21 million. Among them, 210 thousand are pre g by the split team foundation, which is mainly used to encourage early developers to invest in ecological construction and foundation operation
Song Qinghui, a famous economist, said that e to the lack of regulatory policies and the extremely low threshold of user participation, IFO itself may be suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising and financial fraud. Many new virtual currencies born through IFO have little value, and there may be fraud and fraud, Investors need to pay enough attention
According to Shi Qingwei's analysis, on the one hand, IFO will cause great division in the community; On the other hand, the people who issue IFO are basically some investors, and few of them really do the Ifo project in a down-to-earth way. Because they do not have strong executive power and values, it is difficult to do the Ifo project. To put it bluntly, some IFO projects are short of money, and they will not do it after cash out, and there is no particularly big risk. Just intensify market acquisition and cut leeks. The most typical risk is fraud risk, and the other is the risk of market operation. Some investors have been trapped in the Ifo projectaccording to Zhang Yexia, senior researcher of Yingcan consulting, first of all, there is no clear definition of IFO financing activities in China's law, and there is a risk of being prohibited; The second is fraud risk. With the rise of the concept of IFO, it is easy to attract criminals to use concepts such as "mainstream currency bifurcation" and "blockchain technology" to attract investors, but in fact there is no so-called token issuance and technology research; The third is the technical risk. At present, the technologies and standards of mainstream currencies, such as bitcoin and Ethereum, are different. There is no same technical standard, and the technical level is also different. Therefore, the hidden dangers of technical security can not be ignored
Chen Yunfeng believes that for the financing behavior in the name of IFO, the investors can only obtain the value-added income through the digital currency trading market without the actual application scenario of the bifurcated currency itself. This form of financing activity has not been clearly defined in law and needs to be regulated by the relevant departments
Hong shuning, chief researcher of the blockchain Laboratory of Suning Financial Research Institute, believes that the risks of IFO are manifested in the following aspects: first, there may be serious loopholes in changing the agreement without careful consideration; Second, the software released in a hurry will inevitably have a lot of bugs; Third, every IFO will divert some miners, causing fluctuations in the trading smoothness of bitcoin; Fourth, e to the low acceptance of bifurcated currency, the price fluctuation may far exceed that of bitcoin, which is unfavorable to investors
At the same time, Hong shuning said that in the real sense, IFO should not pre dig because it goes against the original intention of bitcoin development, fairness and freedom. In fact, like ICO, IFO is a disguised means of financing. Teams that need to make profits in advance should issue their own digital currency, not under the banner of IFOis illegal
The concept of 21 million
bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, 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
bitcoin is not issued in unlimited quantity, which is different from most currencies. Bitcoin does not rely on a specific currency issuer. But according to the specific algorithm, through a large number of calculations. Its circulation is controlled by software algorithms. The total number is 21 million
extended materials:
generation principle
starting from the essence of bitcoin, the essence of bitcoin is actually the 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[ 10] In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client. After installing the bitcoin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
then why should I say that lightning bitcoin is a great currency experiment? We compare lightning bitcoin to a free economy with three major stakeholders: developers, miners and holders
so far, no blockchain project can effectively govern the three. Why? The reason is very simple. In an ICO project, the developers, coin holders and even miners are the same group. It's easy to understand. Why should he give the best interests to the ICO holders? This is obviously not in line with human nature. The reason why lightning bitcoin dares to do chain governance is related to the issuing mode of lightning bitcoin. LBTC's "governance on the chain" is another attempt to "decentralize", which is also very eye-catching. Dpos mechanism determines that there are 101 nodes in the network. At the same time, unlike pow, the right of choice is in the hands of the coin holder. These nodes will be elected by the vote of the coin holder. When the node does not act, the user can vote out of the network. According to last week's weekly report, LBTC's block browser has also added this function, which can view the operation of nodes in real time. It also paves the way for LBTC's "chain governance". In the LBTC system, all coin holders can vote to decide whether the project development proposal will go or stay, and all members of the organization can participate in the decision-making and operation of the organization. In addition, the 5000 standard of lockup after the election of the lightning node ensures that the node is both a mine pool and a coin holder. In this way, the relationship among miners, developers and users is well balanced, and the foundation of an autonomous organization is formed.
It is obtained by adding vvpool uupool to mine
the complete bitcoin diamond full node wallet can also be used to mine BCD< br />
therefore, we used graphics cards to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine
