Is there any staff reduction in the lebit mine
About bitcoin, the news is flying all over the world these two days
specifically, a foundation called BTN foundation announced that it has set up a bitcoin bifurcated development team to launch a new bitcoin bifurcated BTN. Now its official website is online, which is called btn.kim. Two days later, bitgo, another bitcoin development team, announced that it would fork out from bitcoin. Its name is BTF, which literally means "bitcoin faith"
according to Yao yuan, a well-known bitcoin columnist, bitcoin will "have 10 children" in December, and will at least bifurcate out of 10 "children" such as BCX, SBTC and LBTC
as soon as these things happened, the bitcoin market began to fluctuate again, some investors blew up, and all kinds of rumors came out: why so many forks? Is bitcoin out of order
in fact, the bifurcating of bitcoin is far more complicated than what it shows. If we don't explain its historical background clearly, we really can't understand what happened
< b > the origin of bifurcations: the origin of the bifurcations of bitcoin has existed. The so-called bifurcations refer to the accounting differences caused by different underlying protocols. According to Xue Hongyan, director of the Internet financial center of Suning Financial Research Institute, bitcoin is jointly maintained by a number of point-to-point decentralized nodes. The orderly operation of the whole system depends on the consensus of all nodes, that is, there is a set of recognized standards for key issues such as which transactions are acceptable and which nodes have accounting rights. This set of standards is deployed in the underlying protocol of blockchain and implemented automatically
but nodes are operated by people after all, which is the so-called "miner", but everything operated by people will be different. For example, the miners of some nodes go online every day, while the miners of some nodes go online occasionally; Some nodes are in the eastern hemisphere, some nodes are in the Western Hemisphere... In a word, e to various reasons, over time, bitcoin has different underlying protocols in different nodes
if different versions of underlying protocols are running in a node, different standards will appear, which will result in bifurcation. If the nodes can deal with these version differences and finally form a unified standard, the bifurcation will eventually disappear, which is called soft bifurcation. If the difference cannot be eliminated, when some nodes continue to run different versions of the protocol, the bifurcation will continue, which is called hard bifurcation
it's easy to solve the problem of soft bifurcation, that is, if the account book is wrong, just modify it. Hard bifurcations are not easy to solve. No one thinks he is wrong and explains them according to his own standards. In the end, he can only go his own way and keep his own account. At present, bitcoin bifurcation refers to hard bifurcation
< b > the first bifurcations: the first hard bifurcations of bitcoin technology upgrade are purely technical reasons. The settlement performance of bitcoin itself is limited. According to the original technical agreement, bitcoin can only support up to seven settlements per second. This was not a problem in the early days. With the fire of bitcoin, more and more people flocked in, and the settlement became more frequent than ever. At this time, the original technology was not enough
therefore, in the middle of 2017, some miners proposed new technology agreements, but the other miners did not agree with them. Eventually, both sides held one end and ran their own underlying agreements, which was the first bifurcation in the history of bitcoin
However, with the development of bitcoin trading means, speculators graally regard the bifurcation as a means of money collection, which leads to a great change in the nature of the current bifurcationthe principle is that each bifurcation is essentially equivalent to the issue of a new digital currency, which is linked to bitcoin. The target audience is larger than the general ICO, and it is easier to be accepted by ordinary users than issuing a new digital currency directly
because the team that creates this kind of bifurcation takes the lead, it is very easy to control the transaction of the new currency, especially in the early stage, and it only needs a small cost to control the price trend of the whole currency. This leaves a lot of room for speculation. The forked team only needs to make the new currency accepted by the users, and then it can artificially raise the price to a sky high price. After the real users come in, they can sell all the money they hoard, and get high profits out of thin air
on October 25 this year, a domestic team forked out bitcoin gold (BTG). Two days before the forking, Jiang Zhuoer, CEO of leibitchi, denounced the forking as money looping: "Liao Xiang, founder of BTG, had g 200000 BTG coins in advance before the forking, and wanted to convert them into 20000 bitcoins, looping 80 million yuan."
The advantage of bifurcations can be seen, so that the word "bifurcations create value" has become popular in the field of currency speculation. For this reason, a new word "IFO" - first token issue has been derivedHe Sheng, a well-known financial blogger, once told the media that most of the so-called IFO may evolve into the operation of collecting money by harvesting leeks. "Many previous ICOS are doing IFO, and ICO needs to write a white paper and go to the stock exchange to gain market recognition, while IFO does not even need to write a white paper."
this also explains why bitcoin is becoming more and more profitable. To put it bluntly, everyone wants Nakamoto
Can< b > not bifurcate
whether it's Hong shuning of Suning finance, or Mike & Chen, CEO of bitgo, a bitcoin wallet software provider and one of the project leaders of segwit2x; Mike belshe, the instry actually refuses this bifurcation of bitcoin. In fact, real blockchain practitioners have always hated speculation. At present, the leading enterprises in the domestic blockchain instry have clearly expressed their opposition to the overflow of bitcoin bifurcation. For example, when Xunlei launched the first popular blockchain project in China, its CEO Chen Lei said in an interview: "Xunlei opposes all speculative activities using blockchain, so it is definitely against bitcoin for the purpose of speculation and leek cutting arbitrage."
However, to solve this problem, it is not enough to have an attitude alone, but to have specific means. The best way is not to let bitcoin bifurcatethis is difficult to achieve. Bitcoin's own technology is a relatively primitive blockchain technology with limited computing power. It can barely cope with the previous transaction scale. In view of the current situation of bitcoin fire, it is difficult to support. So sooner or later bitcoin will have to solve the problem of its own computing power
but there is no hope at all. With the innovation of blockchain technology, there will always be some new ways. For example, the shared computing proposed by Xunlei can effectively improve the total amount of computing power and rece the cost per unit of computing power without changing the existing hardware facilities. If bitcoin is combined with shared computing, it can effectively solve the problem of bitcoin's computing power limit without new bifurcation
secondly, the bifurcations for the purpose of cutting Chinese chives can be supervised by means of supervision. For example, compared with the real name system of special currency wallet, the real name system of transactions can effectively prevent the risk of Financial Bureau. At present, the real name system has been implemented in some blockchain projects, and has achieved good results. For example, Xunlei's blockchain is the first blockchain application to introce the real name system in China, which basically eliminates the hidden danger of malicious speculation
in a word, there is a way. It depends on whether bitcoin players accept it or not, and there is a process to implement it. It takes time. Therefore, at this stage, it is better for us to stay away from the bifurcations of bitcoin in various names
PPLNs: (the purest Group mining) full name is pay per last n shares, which means "pay income according to the past n shares", which means that once all miners find a block, You will allocate the currency in the block according to the proportion of each person's own shares Share means share)
in PPLNs mode, luck is very important. If the mine pool can find many blocks in a day, then everyone's dividend will be very large. If the mine pool can't find any blocks in a day, then everyone will have no income
PPS: pay per share mode --- this mode is to pay for each share immediately. The expenditure comes from the existing bitcoin funds in the mine pool, so it can be withdrawn immediately without waiting for the block generation or confirmation. In this way, the operation behind the scenes of the pool operators can be avoided. This method reces the risk of miners, but transfers the risk to the pool operator. Operators can charge fees to make up for the possible losses caused by these risks
in order to solve the problem that PPLNs sometimes has a high profit and sometimes has no profit, PPS adopts a new algorithm. PPS estimates the daily available mineral resources of the mine pool according to the proportion of your computing power in the mine pool, and gives you basically fixed income every day
do you feel that this is a stable job? In fact, in order to avoid the risk of loss, the PPS model often charges a high handling charge of 7% - 8%< DGM: Double geometric method. It combines PPLNs and geometric reward type, so that the pool operator can avoid part of the risk. The pool operator will collect part of the excavated currency in a short time, and then return it to the miners with normalized value, such as charge and discharge of electric capacity. If you are lucky, you will get less money for each block and more money for poor luck
175btc: the mining node of 175btc works on a shares chain similar to bitcoin blockchain. Because there is no center, it will not be attacked by DOS. Unlike other existing mine pool technologies, each node's working block includes bitcoin paid to the owner of shares in the early stage and the node's own bitcoin. 99% of the reward (50btc + transaction cost) will be distributed equally to miners, and the other 0.5% will be awarded to those who generate blocks
bitcoin home has a detailed introction.
the issuance of bitcoin does not depend on indivials or teams, but through a process called "mining". By solving the problem of cryptography, people get the right to create new blocks and get rewards. It can be said that the new bitcoin is proced to reward miners to verify blocks. In the beginning, 50 bitcoins were awarded for each block packed. Nakamoto designed a set of rules. For every 210000 blocks excavated (about four years), the reward will be halved. This is what we call "halving" event
the first half was at the end of 2012, when 50 bitcoins were awarded to the 210000 block, but only 25 bitcoins were awarded to the 210001 block
the second half took place in the middle of 2016, and the reward was halved again, so 12.5 bitcoins were awarded in 420001 block
and so on...
until around 2140, 21 million bitcoins were g up, and then they stopped rewarding
Why do we need this half design? If bitcoin is issued too fast and there is no circulation limit, there will be a large amount of bitcoin in circulation in the market, and it will definitely be greatly devalued. One thing to remember: bitcoin is valuable. First, the number of bitcoins is fixed, that is 21 million; Moreover, through the halving process, inflation in the bitcoin economy can be suppressed
the third halving will take place in May this year. Let's wait and see.
