When did the mining game start
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
Bitcoin was born in 2009, and it has entered China since it appeared
extended information:
bitcoin:
bitcoin can be used to cash and can be 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
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
generation principle:
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. 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

In 2017, blockchain technology is undoubtedly a new wave of technology after the mobile Internet. From the three dimensions of technology implementation, commercial application and commercial realization, blockchain is expected to become a new technology after the mobile Internet, which will once again subvert people's digital lifestyle. At present, the new technology wave of blockchain fascinates more and more developers. Therefore, Neo, a non-profit community blockchain project, joins hands with Microsoft to open the first domestic blockchain developer competition, aiming to proce more excellent applications based on Neo blockchain and Microsoft's development environment and tools, so as to form a strong application ecology for blockchain developers
"People are using blockchain technology in a more interesting way as the basis for 'decentralized applications' rather than just applications like financial technology and cryptocurrency," said Mike Mason, technical director of the office of chief technology officer of ThoughtWorks, a global software consulting firm. You know, "blue ocean" has never lacked players. Some Internet companies are trying their best to land on the beach, and have established the blockchain instry market as an inevitable choice for development. In China, netxin technology, a wholly-owned subsidiary of Xunlei, has used blockchain technology in the innovative cloud computing mode - "shared computing"
earlier, Xunlei implanted the concept of sharing economy into the field of cloud computing, and created an original" sharing computing "mode. By collecting users' idle computing resources, Xunlei transformed them into innovative cloud computing services for enterprises, On the one hand, it can effectively solve the social contradiction between the shortage of social computing resources and the high cost of computing, on the other hand, it can greatly rece the operating costs of enterprises. In August 2017, Xunlei launched a new sharing economy intelligent hardware player cloud. Its significance lies in that in the shared computing ecosystem, Xunlei joined the blockchain technology to issue player coins to users who share idle resources such as bandwidth, storage and computing power through the player cloud intelligent hardware
playcoin is a digital asset created based on blockchain technology in the thunderbolt shared computing ecosystem. With the launch of playcoin, Xunlei has become the pioneer of blockchain technology in China, and also has many advantages in its shared computing. Firstly, playcoin, based on shared computing and blockchain technology, ensures that the payment and income of users' shared computing resources and content are equal through smart contracts, which cannot be denied; Secondly, through decentralized accounting records, all transactions are true and transparent; Third, register users' right and modify records through blockchain to protect users' right from infringement
in fact, blockchain technology has strong advantages in network security, cross-border payment and other fields, and also has important value for building a community of destiny in cyberspace. On October 31, 2017, Chen Lei, CEO of Xunlei group and CEO of netxin technology, put forward the all in blockchain strategy and announced that Xunlei will increase investment in blockchain technology starting from the player cloud to explore the application of cloud computing and blockchain technology integration. On the day of the press conference, playmaker cloud also signed a right content distribution agreement with 4K garden, trying to integrate shared computing and blockchain technology to provide a platform for right distribution and content distribution. In the future, blockchain will generate more application scenarios in thunderbolt's shared computing ecosystem. Xunlei's innovative attempt may give more inspiration to developers of other blockchain technology applications
at the same time, as a leading enterprise in the blockchain application market, Xunlei is also actively guiding the healthy development of blockchain applications, insisting on not doing ICO, not going to the third-party trading platform, and severely cracking down on the third-party platform for illegal trading of customer coin, and cracking down on speculation and speculation through such measures as the real name system of customer Coin Wallet. Therefore, blockchain application developers should also abide by the law and avoid risks
based on the blockchain technology, Xunlei's "player cloud" takes the lead in building the C-end application of China's blockchain technology, which promotes China's blockchain technology to participate in the ecological development of global blockchain and creates important value in the development of digital economy“ The development history of the Internet is a history of innovation and Entrepreneurship of Internet talents. " The development of blockchain also needs a lot of talent support. We are looking forward to the birth of "blockchain +" Application in the first domestic blockchain developer competition
conservative play: hang up for 24 hours, 2m upload bandwidth, more than 200g free space. The daily output of crystal is equivalent to 0.68 yuan, about 500 yuan in two years
wise play: according to the hang up time, upload bandwidth and storage capacity, the number of play coins proced by mining every day changes. At the beginning of the 12th, each machine proced about 70 coins a day. At present, about 20-30 coins a day.
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)
CPU mining → GPU mining → professional miner mining → mine pool mining
on January 3, 2009, the founder of bitcoin, Nakamoto Tsung, g up the first batch of bitcoin with computer CPU
with the recognition of bitcoin, more and more people are mining, the computing power of the whole network is rising, and the difficulty of mining is graally rising
the first graphics card mining software was released on September 18, 2010. A graphics card is equivalent to dozens of CPUs, and the mining capacity has been significantly improved
later, someone invented a professional mining equipment based on mining chip, namely mining machine. At present, the instry-leading ant miner is equipped with nearly 200 bm1387 chips, which is equivalent to the computing power of more than 30000 GPUs
as more mining machines are added to mining, it is difficult for a single mining machine to dig bitcoin. As a result, the miners concentrated their mining machines and formed mines and pools.
