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

2. I also know that there is a possibility of cheating!!!!! But I buy hit currency one yuan to buy 100 to his 2000 yuan, in case I say in case I become a multimillionaire that!!!!!!! My chance to become a multimillionaire in this life is possible! If you can't change it, you should buy wine for the swindler

"Stock god" Warren Buffett earnestly advised: "don't waste your hard-earned money on investing in bitcoin!" Now, many financial experts agree with Mr. Buffett

According to Carson, blockchain will realize the equal exchange of value and services. This will change a country's economic situation and improve it. Cathy Curtis, founder of Curtis financial planning, and Carolyn McClanahan, founder of life planning, also heard about bitcoin investment opportunities from clients. "I did talk to clients about cryptocurrency and bitcoin," Curtis said Curtis added: "now what I want to say is, if you want to invest in it, go ahead. But I don't see the value of it. More cautious customers will make a detailed consultation before deciding whether to invest in it. Now don't spend too much money on bitcoin, because you've missed the opportunity. "

although Curtis admits that he does not see a positive side in bitcoin investment, he is optimistic when it comes to blockchain technology. "Blockchain technology is not easy to be attacked by hackers, it can be applied to many other instries," Curtis said "Blockchain technology is great," McLanahan said when explaining blockchain technology to customers "Blockchain technology will be able to do a lot of great things, so it makes sense to think of it as an investment opportunity," the person said. But we will do that through a diversified portfolio. "

4. The game between the two forces of the currency circle is controversial on whether to expand the capacity
two key figures in the bitcoin field have developed another version of bitcoin. They are Gavin Andresen and Mike Hearn, the chief developers of bitcoin
for several months, Anderson and Hearn have been arguing with the other three chief developers of bitcoin: whether the blocks processed in bitcoin transactions should be further expanded from the current 1MB, so as to be able to process more than three payments per second
this new version of bitcoin, called bitcoin XT, increases the capacity of the block to 8MB and can complete 24 transactions per second. Although it is far lower than visa's processing speed of 20000 transactions per second, it will increase every year in the future, so bitcoin will continue to grow
opponents of bitcoin XT believe that increasing the block capacity may undermine the original intention of this decentralized payment system, because the extra computer memory requirements may crowd out thousands of independent "nodes" from the network< Some people think that this split marks the end of bitcoin. But he told Reuters on Tuesday that the cryptocurrency will continue to exist, whether or not it is accepted
"if we thought it might ruin bitcoin's future, we wouldn't do it." He said. He added that since last Saturday, about 10% of the nodes have agreed to use bitcoin XT.

As the saying goes, "if you want to plant flowers, they will not blossom, but if you don't want to plant willows, they will become shade.". McDonald's, a fast-food giant that can't compete with virtual currency and blockchain, issued a "maccoin". Within an hour after its release, its "value" soared more than 30 times! 6.2 million McDonald's commemorative coins are given away for free all over the world, and they are fried up to 3000 yuan on the Internet

since the birth of bitcoin, countless later "money circle bigwigs" have tried to the miraculous surge until bitcoin's own value has been "cut off"

a big Mac in the domestic "golden arch" restaurant is about 21 yuan. However, after the release of the commemorative coin on August 6, the price of a maccoin was quickly fried to more than 600 yuan, and a set (5 pieces) was even fried to a maximum of 3000 yuan

6. Bitcoin is likely to split. Some time ago, there were two different voices about the future development of bitcoin
two key figures in the bitcoin field have developed another version of bitcoin. They are Gavin Andresen and Mike Hearn, the chief developers of bitcoin
for several months, Anderson and Hearn have been arguing with the other three chief developers of bitcoin: whether the blocks processed in bitcoin transactions should be further expanded from the current 1MB, so as to be able to process more than three payments per second
this new version of bitcoin, called bitcoin XT, increases the capacity of the block to 8MB and can complete 24 transactions per second. Although it is far lower than visa's processing speed of 20000 transactions per second, it will increase every year in the future, so bitcoin will continue to grow
opponents of bitcoin XT believe that increasing the block capacity may undermine the original intention of this decentralized payment system, because the extra computer memory requirements may crowd out thousands of independent "nodes" from the network< Some people think that this split marks the end of bitcoin.

"if we thought it might ruin bitcoin's future, we wouldn't do it." He said. He added that since last Saturday, about 10% of the nodes have agreed to use bitcoin XT
however, it should be noted that the future development of bitcoin is decided by miners, and the computing power they have is the right to vote. China's five bitcoin mines account for more than 60% of the computing power in the whole network, and the decision-making power is still in China.
