Tut tut... 9 points. It's very interesting to say, the day before yesterday I went out to take the subway and met a beautiful woman. One eye is amazing, two eyes are sinking... There is a hint of charm in the purity, staring at these eyes for a long time will make people drown in them willingly. After a while, ah, ah, I have sat and stood... Einstein's theory of relativity said that walking with a beautiful woman for an hour feels like a minute. Ah bah, the focus of today is... what? center? Go to his center. Well, decentralization has flapped its wings as a butterfly in the Pacific Ocean, and the blockchain is rising. Beep beep...the vehicle starts, please sit down and hold on.
1. The starting station - the birth of blockchain
In 2008, the global financial crisis changed the days of bicycles. My hometown, Satoshi Nakamoto (Chinese people are very smart) children's shoes, take off your shoes, step by step, go through vicissitudes of life, with a longing for freedom and contempt for the evil capitalism, of course, as a code farmer, also I can only type the next line of code with pain and tears. In this way, the blockchain has come to this era that requires faith.
2. The second stop - what is the blockchain
To put it simply, distributed ledgers are a way for all people to participate in bookkeeping.
There is a lot of gossip, you are keeping your account book, Tencent is keeping the account book of WeChat, and Ali is keeping the account book of Taobao. But in the blockchain, everyone can participate in bookkeeping, and whoever keeps books fast, keeps books well, and does it well will be the one. What about the others, watching a play, eating melon seeds and setting up small benches? Of course not, everyone has to keep accounts. It’s just that when people get better, others have recognized it. You still owe 300 to Li Si, and Li Si owes 500 to Wang Wu. You use both hands and feet. I’m sorry, you stop and stop, back up with peace of mind, go back and study hard, welcome. visit. Well, that's it, everyone has a record of every account.
3. The third stop - what is the blockchain
1. High security.
Hey, I don't believe it. I have told you how much money I have saved. I am still safe. Will I still go out at night? Don't get me wrong here. A block only stores a record and does not represent specific information. For example, you have deposited 300, and the block records "#%&¥%&@&!" Such a string of Martian texts, who knows what you are doing. Of course, you can also tell everyone that I have 50 cents and I am proud. Where does the safety come from? Think about it, everyone has stored a record for you, not just your own ledger (decentralization), and theoretically it cannot be destroyed, unless you represent the moon to destroy us, including yourself. Furthermore, it is impossible to cheat, unless you have a 59E fan base, 51% of block groups or decision rights, otherwise the records cannot be tampered with.
2. Solve the trust problem.
In the past, liars were all over the world, and no one knew who was a liar. In other words, A has gone through a lot of hardships, climbed mountains and waded, traveled thousands of miles, and negotiated a deal with B. A said, 100. B said, 500. A said, 300. B said, ok, you said 300, just 300. At this point, the transaction interview is over. When it was time to hand over the money and deliver the goods, A slapped his pocket and the money went home. Let me tell you, this A is not easy, and I came all the way here for such a deal. At this time, B came up with a plan, let's go to the blockchain and tell everyone about our transaction. The big guy took out his own notebook, hey, on March 22, 2018, AB completed a transaction, specifically xxx, and A did not pay. Whoever repudiates, whoever hehehehe. Invisibly, trust is built on the blockchain, in everyone's heart (open and transparent).
3. Improve efficiency
I don’t know if the big guy who raised the provident fund feels it, it’s a trouble, first go to some house to get a certificate to prove that you don’t have a house. Go to that company to get a stamp to prove that you are eligible to apply. Come here and get a photocopy of your ID to prove it's you. A bunch of messy, extremely centralized systems. If you say, if you say, hey, in the blockchain system. From the moment you were born, you are you, and everyone knows it. I don't have a house, and the big guys know it, and I can't afford it in Beijing, Shanghai, and Guangzhou. Check in the block, I don’t know what, and it’s very credible, the big guy’s face. Huh, huh, 3 seconds, huh, huh, perfect withdrawal of provident fund, not to mention the efficiency.
Terminal - The Future of Blockchain
At present, information technology is becoming more and more developed, the digitalization process is accelerating, and the blockchain is born. The development of the blockchain has prompted humans to quickly establish a new type of "organizational structure". This autonomous organizational structure exists in the blockchain network, in the protocol, and in the minds of humans. Blockchain will eventually be one of the constituent infrastructures of the future world. Oops, a group of cows were blown away, and Amway made a wave. Having said that, there is a long way to go, or the 2-year Long March, or the 7-year Anti-Japanese War, requires the efforts and struggles of you, me, and others.
