After playing with two unreliable college students riding their little Yanmar frantically looking for the ancient battlefield for a few days, it was time to make an appointment with Boss Wu. Boss Wu of "Fat Limbs Pulling Jade Flowers" really lives up to his reputation, he is a fat man, but he is not very fat, maybe he is middle-aged.

Nowadays, 80 or 90% of people are blessed in middle age, their families have been established, their jobs have been stabilized, and their enterprising spirit has been consumed. People like Wang Fang who are so poor that they don't want to want it and who spend all day thinking about some strange mathematical, physical, biological, and social science problems are simply rare.

What's more, Wang Fang, who is also more concerned about health, will find a way to reduce the amount of food a little as soon as he sees that his lower abdomen has a tendency to bulge, so it is really well controlled.

After meeting, Boss Wu was very envious of Boss Wang's figure, he looked very young, and when he compared his age, Boss Wang was a few months longer than Boss Wu, which was really emotional. Boss Wu said with emotion: "My two sons are all over the ground with soy sauce. ”

Boss Wang: "Boss Wu has many sons and many blessings." ”

Boss Wu: "What a blessing, two troublemakers, they actually caused trouble for me, I still envy you, single nobleman." I can play as much as I want, why couldn't I bear the pressure back then? ”

Boss Wang smiled and said: "Don't be modest, Boss Wu, I have seen a qiē from your micro-expression, although the process of raising a baby is hard, but there is also a sense of achievement, isn't it?" Like us, we have no worries, and we feel that we are floating in the sky, and our feet are not touching the ground. Eh, I'm straight to the point, and in the future there will definitely be a real house that floats in the sky all year round.

Now Google's balloon is the prototype of this kind of house, using helium to generate buoyancy, and there is a layer of air inside, which rises and falls by controlling the air content, and follows the atmospheric circulation to make a trip around the world. In the future, when the material can be made very light, someone will use this material to make a house that flies around the world, and I don't know if I will have a house like this at that time. Ha ha! ”

Boss Wu also smiled: "Interesting, I'll also have a set, at that time, my bear children have grown up, I can't take care of it, I should enjoy life." ”

The place where they met was a huge natural lake, a great attraction in this ancient city, and tourists were full of tourists, who wandered on the edge of this big lake, looking at the white sails in the middle of the lake, and they were in a happy mood.

Boss Wu: "Look, the sailboat is also quite fun, and those boys have a lot of fun." My physique is useless, but Boss Wang, you start playing. ”

Boss Wang: "Looking at the hard work, tossing and turning, I like to lie on the boat and have fun." I'll play with it when I sell the site. By the way, tell me the details of the household. ”

Boss Wu enthusiastically introduced his own set, but he was a little unhappy that the other party was reluctant to tell himself what the website was at this time, and Boss Wang asked something that made him feel a little uneasy: "Can you trade with Bitcoin?" ”

All formal transfer procedures involve a fee, and it is said that the cost of handling fees in Bitcoin is very low. But Boss Wu is old and not willing to do this, saying: "I heard that Bitcoin is very unreliable and fluctuates greatly." ”

Boss Wang: "You can use futures contracts to hedge risks, buy a contract and sell it in a few days, it's still cost-effective, I'm not an intermediary, but Boss Wu can study it, and the savings are all white money." ”

Boss Wu: "Actually, I don't really understand, why is Bitcoin valuable?" Or, Boss Wang will give me popular science? ”

Boss Wang: "The current market capitalization of Bitcoin is $6 billion. It is completely based on the confidence of investors in this virtual currency. The source of this confidence lies in the fact that Bitcoin has created a new financial system, a distributed financial system that is theoretically impossible to hack.

At the heart of this system is blockchain technology, which Goldman Sachs, Microsoft, IBM and other high-tech companies and high-end financial services companies believe will replace the traditional financial system. Even the People's Bank of China is testing digital currency, but I don't know if it's blockchain, I think it should be, the People's Bank of China also has experts.

Before the advent of Bitcoin, computer scientists believed that a system distributed in the personal computers of Internet users who could not be fully trusted was impossible because it would not solve the Byzantine general problem. There is also a scientist who has written a paper to elaborate that theoretically, as long as 30% of computers cannot be fully trusted, the system cannot be safe and reliable.

Byzantium is the capital of the Eastern Roman Empire, this empire has a vast territory, and the armies are far apart, much like a distributed node on the Internet.

There will be some traitors among these generals, the army will be far apart from the army, the messenger who sends the message may be killed on the way, or because of the distance of the army, it will not be possible to reply immediately after receiving the message, and the sender will not be able to confirm that the message is indeed lost, and the guide zhì cannot achieve consistency. On distributed computing, it is impossible to try to achieve consistency on asynchronous systems and unreliable channels.

So the Byzantine generals had a big problem.

As soon as the 30% theoretical value of the paper came out, everyone thought that the distributed computing system was out of play, but I didn't expect that the inventor of Bitcoin, codenamed Satoshi Nakamoto, or an institution, actually came up with a trick - through guò mining and rewarding transaction fees to gather a large amount of computing power, because the rewards are rich, the computing power is snowballing bigger and bigger, and now, no institution has the ability to make a computing verification system that can threaten the Bitcoin network.

This reliable system of calculation and verification is the most valuable thing of Bitcoin, which is equivalent to Bitcoin expanding the number of Byzantine generals by N times, and the number of traitors has become a drop in the ocean and not worth mentioning. ”

Boss Wu: "It sounds like this, it's a little bit of a spectrum, but the market value is still too small, 6 billion dollars, which is not much for a currency, if there is a 60 billion dollars, I will be convinced." The U.S. Federal Savings Insurance Fund is only $50 billion. The market capitalization is very small, no wonder it fluctuates greatly. Are you so optimistic, you must have bought a lot of bitcoins? ”

Boss Wang: "No, I am very optimistic, but the anonymity of Bitcoin has been abused, and the low transaction cost has not been taken seriously, the result is that the state does not encourage it, and a certain treasure is not allowed to buy and sell, I usually buy and sell Lufax's cash management products, and I have no time to take care of this financial system that is still evolving."

The problem is that Boss Wu is different, you see, if you can reduce the handling fee, it is a good business in itself, it is worth studying, Boss Wu has been famous for so many years, and there are many elite soldiers under him, I am a second-rate programmer, so I should leave this kind of thing to Boss Wu. ”

Boss Wu: "Where, I don't know much about technology, and I'm not too confident about my subordinates, so I admire Ma Yun, I don't know anything, but I take a group of technical masters to fight the world." ”

Wang Bang laughed: "If Lao Ma understands technology, I am afraid he should think that the future direction of Alipay is blockchain technology, otherwise, Ali is such a huge volume, and it will be ugly to die if a security crisis breaks out one day." Ali is particularly optimistic about cloud computing, hehe, but everyone knows that blockchain is likely to subvert the current cloud computing in the future. Since the reliability problem of distributed computing systems has been solved, it can theoretically be used anywhere, and cloud computing can of course also use blockchain.

The current computer system with the center of data as the core has great security risks, the software is becoming more and more bloated, and the vulnerabilities are emerging in an endless stream, and only distributed can disperse the risk. Recently, Ah Hua Dog has just broken through the last IQ self-confidence of human beings and conquered the top game of Go in human beings.

This is a general deep learning method, and Ahuagou's algorithm was published in Nature. In the future, there will be top hackers who will suddenly slap their heads and start to use the principle of Ahuagou to collect 0-day vulnerabilities, and get all the vulnerabilities that have appeared in history like collecting Go games, and then let hackers AlphaGo look for vulnerabilities of various institutions on the Internet 24 hours a day without eating or drinking.

I'm straight at it, and when that day comes, there will be a large number of websites that have been breached. That is the era when blockchain technology began to gain popularity, because traditional computing systems were already too dangerous. I also thought about being a hacker before, but it was too hard to find a 0day, so I gave up, now it's okay, Ah Huagou can help hackers find 0day, that is a hacking technique once and for all. ”

Boss Wu exclaimed: "Boss Wang's idea is very interesting, it's really late to see each other, and we will have a lot of contact with each other in the future, and I can hear a lot of wonderful ideas from you." I'm curious about what the website you want to close is, hehe, I look forward to you finding a buyer soon. ”

Wang Bang laughed: "I have always been a keyboard warrior, and my ideas are whimsy, and the website I made is also half a pound and eight taels with your previous beauty picture station." The ideal is gorgeous, the reality is very simple, this is the real reality. ”

Boss Wu smiled: "Boss Wang is a real person!" Suddenly I feel that the alpha dog has a bright future, no wonder Google's stock rose by 10 billion dollars after a game of chess, and sure enough, some people are still optimistic about this so-called general deep learning technology. ”

Wang Bang: "Well, this is the beginning of an intelligent revolution, the real investors of the Alpha Dog room also include Musk, this guy has built a Tesla factory in California for the first time, and the factory has not been built in California for many years, let alone a car factory, it can be seen that Musk is playing with the automation factory very slippery, and it is introduced in the book "Maker", which may be an unprecedented factory with a super high automation process.

For the first time in this factory, the advantage of talent close to the high-tech center has outpaced the advantage of low-cost workers, which is also a major event worth noting. Also, Tesla is made of aluminum alloy, which is 3 times more expensive than iron. This is also an industrial trend, no wonder Hebei's steel mills are losing money and can't be sold. ”
