BTC block out time
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

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 is a kind of network virtual currency. 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. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

the number of nodes of LBTC is 101. Compared with 21 or 51 nodes, the coin holder can vote for 51 nodes at most once in the wallet of LBTC, which further reces the risk of centralization; LBTC can output blocks stably in 3 seconds, and the block size of 2m ensures that LBTC is 400 times more efficient than bitcoin, and the transaction speed can reach more than 2000 transactions per second; The most important difference between LBTC and other projects is that LBTC's dpos mechanism has the rule of irreversible block. When the number of block agents reaches 90% or more in one round, or when the number of block agents exceeds 70%, the first block in the previous round can be considered as irreversible, so as to prevent bifurcation.
Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years
when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators
extended data:
after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%
maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply
this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
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)
