He Baohong, computer majored, engaged in research on the Internet for more than 20 years, in block chain concept heat of the moment, but He Baohong look on coldly, he said, "we have been will overestimate the short-term effects of a technology, and underestimate the long-term impact of a technology," he himself for technical, social, business, some thinking was recorded in his own WeChat "what thinking" in the public, to read often is suddenly enlighted, sobering,
1 block chain can overturn the Internet?
In the Internet I do in the course of a study of more than 20 years, every few years there is a call the next generation of Internet, there will be some people jump out of the I will replace the Internet now, I want to be the next generation Internet,
Once upon a time a few years of mobile Internet, Internet of things, cloud computing is so to speak, so this from the point of the timeline, we block chain can solve many problems, but there are many problems, has nothing to do with the chain block, block chain is essentially a kind of database technology, so it is the problem to be solved on database technology, also some core issues around data management, but block chain can replace 5 g? Can replace optical communication? Can replace the chip? It's not possible, because each technology's responsibilities are not the same, chain block is a new kind of database technology, can effective management of special data, is not to say that all of the data need to be tamper-proof block chain, we do not need this feature a lot of data, so it never overturn the Internet, it is just a part of the Internet, the Internet several decades of development, it is a process of constantly patch on it, so I always say is merely a larger patch block chain,
2 do not tamper with the really work?
For instance if your privacy was written into the block chain, what will happen?
You have no way to get rid of, or some illegal information, some information should not be on the chain, entered the chain? We may can also delete before, after or court decisions, you may be withdrawn, if the court ruled that this thing must be revoked, removed from the block chain? Similar things will happen, every citizen has the right to forget the forgotten, is the privacy when delete to delete the data requirements, but block chain after coming out, such as some smear on the block chain to me? Can't isn't it? Then this technology is likely to break the law,
We need to prevent tampering with data, but we should be allowed to withdraw, legal legal modify data, can't say what all can't change, this is we went to another extreme, from what can be changed to what all can't change, and we are actually stuck in the middle of the human society, we may make mistakes, made a mistake? Including the privacy data, one thousand on the chain? Back, right? This is should not be right, so I said technology finally will come back again, it's a curse,
3 completely anonymous really good?
Finally you will find that, at the same time of technical advantage, can bring new challenges to our social governance regulation, decentralization, if wrong, its legal responsibility main body who is it? How to deal with this problem? Problems, the main responsibility is inevitable no anonymous will bring a lot of crime, money laundering, smuggling problem, how to deal with? We are in reality a lot of time to implement the real name, take a plane to real name and so on, right? You is to reveal some privacy, or you have to release some privacy, in order to assure safe operation of our entire society, block chain will also face the same problem, if you are totally privacy, the whole society may be more disorderly,
4 can block chain large-scale application in the short term?
We always overestimate the short-term effects of a technology, and underestimate the long-term impact of a technology, now we say block chain will bring a lot of some of the impact of change, a task that is very long, is what will happen in the long run, rather than may occur in the short term, 3, 5 years, you have great changes will happen in the next 10 or 20 years later, said to the crowds will come soon, may cause panic, but this was only to make a public opinion, it will happen, but not now,
Because any one technology from starting to attract attention, to mature require years of time, including its application in specific situations, all technical personnel need to continue to go to grope, to explore, this is all need time, not a technology, 3, 5 year will be large-scale applications,
Since 90 s Internet commercial block chain it should be said that some parts are very similar, including its technical characteristic stress is distributed, peer-to-peer, open, Shared, anonymous, and at first the Internet was criticism and chain blocks are all the same, is that it can be used to do bad things, so it has a remarkable similar, but do you think the Internet history, from the beginning the hype, the nationwide real Internet mass landing or change the world, probably spent 20 years of time, so the chain block can never accomplish this in a few years,
