01 bitcoin split to coin

1. At present, bitcoin has not experienced an influential bifurcation. It's basically a worry about hard bifurcations. In the history of bitcoin, there have been many worries like hard bifurcations. For example, the computing power of a large mine has been close to 51% of that of the whole network many times; In addition, when ASIC mining machine was just born, people were worried about the huge mining computing power of mining machine manufacturers; People's concern about quantum computer's participation in mining is also long-standing; At present, the currency price is low, and mining is graally controlled by several large mines, which may also lead to the emergence of hard bifurcations; Recently, the hard fork crisis caused by bitcoin expansion has once again alerted people. But in fact, this is just a kind of worry, the probability of occurrence is very small

every time there is a hard bifurcation crisis, the currency price may plunge, which is mainly e to the worry of bitcoin.

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 bifurcation

the 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 derived

He 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 bifurcate

this 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

3.

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 bifurcation

soft 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

In the discussion of blockchain, bitcoin and other digital currencies, we often hear the word "bifurcation". So what is bifurcation? What is the effect of bifurcation

blockchain

before talking about bifurcation, popularize a little knowledge of blockchain, so as to help us understand what bifurcation is more easily (if you don't have any concept of blockchain, please read my previous articles, which are all popular words to help you understand what blockchain is)

blockchain, as the name suggests, is a chain composed of blocks. Of course, this kind of chain is just a figurative metaphor. To put it bluntly, data blocks are connected orderly. In bitcoin, the transaction records of bitcoin are stored in the block. The size of the block and the space occupied by the transaction records determine how many transactions can be stored in a block. These transaction records are packaged into blocks, and then the blocks are connected one by one to form a blockchain

We know that bitcoin software, like other software, needs to be updated and modified regularly in order to make it better. So a new version will appear, but not everyone will download the new version, so one miner will run the old version, and some will run the new version. If the old and new versions are not compatible, the blockchain will bifurcate. Because there may be differences between the version blocks and the old version blocks, they cannot be connected to the same blockchain, so there will be two or even more chains, which is called bifurcation

soft forking

soft forking refers to that when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, resulting in temporary forking. This kind of bifurcation will be graally repaired with the upgrading of nodes

hard fork

hard fork refers to the permanent divergence of the blockchain. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually hard fork occurs. Therefore, in the field of digital currency, hard bifurcation often leads to the emergence of new currencies. For example, the hard bifurcation of Ethereum led to the emergence of eth

What is bifurcation? What is bitcoin bifurcation

5. As for whether there is token after bitcoin bifurcation, it mainly depends on whether the wallet supports bitcoin bifurcation
as we all know, there are two common types of bitcoin wallets:
first, the network version, which does not need to be downloaded by users, can directly access the wallet platform through a computer or mobile phone, and use bitcoin wallets
Second, the stand-alone version, which needs to be downloaded from the computer (or the lower end of the mobile phone) and installed before it can be used
in addition, there is a bitcoin wallet (Hard Wallet) similar to U disk
as a bitcoin wallet service platform, coin pack thinks that whether the bitcoin in the wallet will generate new tokens after bifurcation mainly depends on whether the wallet supports bitcoin bifurcation
as a bitcoin wallet, whether it is a network version, a stand-alone version or a hard wallet, it is necessary to compare the bifurcated support of bitcoin before a new token can be generated; Whether there is a new token proct depends on the users
users can also consult the customer service of the wallet to learn about the bifurcations of bitcoin.

6. Fork coin, as the name suggests, comes from the concept of "fork" in blockchain. The early bifurcations of bitcoin were a compromise solution to the problem of bitcoin block expansion
bifurcation means an incomplete upgrade of bitcoin. After upgrading, some UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes, but the upgraded nodes can verify the blocks proced by the UN upgraded nodes, thus splitting the two chains

nowadays, there is a flood of counterfeit coins in the market, which are actually some bifurcated coins

a typical split coin operation is to announce a split coin and give each user a special new "split coin" or "candy" in a ratio of 1:1
after users generally get the new currency after the split, there will be a natural demand for trading. At this time, public opinion can be guided, and the huge number of users and trading demand force the exchange to put on the currency
after the currency is put on the exchange, the holders of the forked currency first use a certain amount of capital to pull up the forked currency, create the illusion of pursuing, and then sell their "pre g" forked currency for arbitrage

but players can also think that some forked coins are valuable, so they can follow up. Therefore, the exchange of forked coins is also valuable. There are still many such activities, such as bitfinx, coin rise, coin safety, etc.

8. As for whether there is token after bitcoin bifurcation, it mainly depends on whether the wallet supports bitcoin bifurcation
as we all know, there are two common types of bitcoin wallets:
first, the network version, which does not need to be downloaded by users, can directly access the wallet platform through a computer or mobile phone, and use bitcoin wallets
Second, the stand-alone version, which needs to be downloaded from the computer (or the lower end of the mobile phone) and installed before it can be used.

9. Bitcoin cash and bitcoin are a pair of soft voice brothers. The predecessor of bitcoin cash is bitcoin. Bitcoin cash is a new type of blockchain asset based on the original chain. On August 1, bitcoin cash separated from the main chain and embarked on the road of independent development
bitcoin cash is the proct of the three-year battle for bitcoin expansion. The main supporters and promoters of bitcoin cash are supporters and developers of large blocks
bitcoin cash is not a kind of bifurcated currency, and bitcoin cash does not meet the definition of bifurcated currency. Bitcoin cash and bitcoin are two different blockchains.
