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

On June 22, 2020, sponsored by golden finance, hosted by node consulting, ipfs100.com, and jointly sponsored by Mackay storage, the "interstellar roaming Guide - IPFs technology and Application Seminar forum" opened in Shenzhen. On the forum, Hou Feng, founder of McKee storage, gave a speech with the theme of "distributed storage revolution in the era of big data"

in his speech, he said that you may think too complicated about a series of mining activities such as filecoin. In fact, the simplest logic of mining is to have a device, and then connect with the official mining software to realize it. The configuration of the mining machine is easy to figure out, and the mining machine itself is a storage server

as for how to identify a powerful mining machinery company, he mentioned that it depends on whether the company has an actual proction plant

the following is the full content of the speech:

Hou Feng: Thank you, host, distinguished friends and colleagues. Good morning, I'm the founder of McKee storage, my name is Hou Feng. First of all, thank our sponsor Golden Finance for providing us with such a good platform for communication. Today, I am very excited to see more and more people join IPFs and filecoin. Today, we will have a good exchange and have a good look at what we can do in this ecology

I often say: there are people who are inferior to others. When we see the development of an instry and the coming of wealth opportunities, we don't know how to get wealth, what can we do? We will come out and have a look at what we are doing, and then we will learn how to earn our own wealth

today, I'd like to give you a brief introction of McKee storage. I have about 20 minutes, from the company's profile to the mining revenue to the team's presentation. Shenzhen Mack Storage Technology Co., Ltd. has been preaching IPFs since 2017. We have been in this instry for many years. From 2018, we formally established our operation and maintenance team, and then went to study filecoin. We are a company integrating design, R & D, proction, sales, centralized management, mine pool development, and IDC machine room construction, So we don't just do one thing, such as technology or sales of machines. We also invested 600 million yuan to build a server proction plant in Jiangxi, with 162 million yuan in the first phase

this is a passage I like very much. Today I would like to share with you, "don't understand business as making money. In fact, the original intention of business is to share. Life is endless. It means the heart. This is the way of business and the right way.". This is a mine pool app that we are developing now. In fact, I shared it with you in a live broadcast on our mine pool PC in April. In the future, we will have our mining income, dividends and purchases in this mine pool app

In fact, what I really want to say today is that mining is very simple. What I understand as mining is that you provide services to others and then get some benefits from them

it's such a simple thing. You may think that a series of mining activities such as filecoin are very complicated. In fact, mining is to have a device, and then connect with the official mining software. So in this device, especially in Shenzhen, Shenzhen is the distribution center of some of our electronic procts, So many of our little friends don't have to worry about the configuration of the mining machine. Today, I can tell you very frankly that the mining machine is our storage server, just a few hardware

today, I really want to give you an estimate of how much money we make by digging filecoin. This is what I saw one day in 2018, when the futures reached 227 yuan. I said, is this our good day finally coming? But it seems that it only took one day to go up and then it came down

this is a picture I cut two days ago. It's 71 yuan. Based on the average price of the two of them, it's 149 yuan. We estimate the profit of about 4 million yuan this time. If we have 50000 or 60000 sets of equipment, we can calculate the total computing power. Our single T computing power calculated by the total computing power is 0.15 to 0.45. If we calculate according to its average value, it is about 0.3 yuan per T. the price of our server is 1950 yuan / T. our single T computing power is until your machine is scrapped

so Mack has been saving 1950 yuan and has been telling you that you can dig for at least one year, and the rest of the time we will dig until the machine is scrapped. Why? Because I often argue that if I'm good, if I'm not, I won't do it; I'm in favor, but he's not. I always use altruistic thinking and want to do something when filecoin comes

therefore, our company has been digging up the machine for 1950 yuan / t until it is scrapped. If we calculate according to the cost of 10t bought by all of you, the cost is 19500 yuan, and our daily income is 448 yuan. Our monthly income is 13450 yuan, and our annual income is more than 160000 yuan. Our payback time is 43 days. In fact, I have been calculating this thing, just to give you an estimated income, but this one is also very strict. It is calculated by some data, not by me. What if the value of filecoin increases 10 times, 100 times, 1000 times? Now let's calculate by 149. What if it goes up to 1490? What if you buy 100t? What about 10000 tons? We just need to believe, because believing is the beginning of all greatness, and only believing can do it

if you buy our server, you will have the following rights and interests: the first is to have the promotion right of Mack storage, give priority to the computer, and get the earliest head mine bonus, the main network
