It is a bit far-fetched to say that the blockchain changes history. After all, it is not a time machine. There is no way to travel between the past and the future, but the emergence of blockchain can change many life stories. This is beyond doubt. Blockchain can prove "your mom is your mother" I remember that there was a very strange news. A citizen who wants to travel abroad needs to fill in the 'emergency contact'. He wrote the mother's name, but the relevant department asked him to provide materials to prove 'your mom is your mother'. What should I do? Going to a government-related agency for a day trip? Or go to the hospital to get a set of DNA, chromosome polymorphism identification package? In fact, it is not assumed that blockchain technology is used on the government's identity authentication system to establish a government blockchain that digitizes all information from the beginning of citizenship and stores it in the blockchain. Since the blockchain technology itself has traceability, unforgeability and distributed features, it makes it easier and safer to query the citizen information after storing the digital identity in the blockchain. Its information can be traced back to the moment when everyone was born, and its reliability is unquestionable. (Only for public information and some parties are authorized to access relevant information) In this way, the above problems can be solved by simply letting visitors visit the government blockchain system. The use of the blockchain in the identity authentication system can also be extended to the abduction action. After the child is born, the DNA, iris and other information are recorded in the blockchain system. Once the abduction event occurs, the relevant system of the blockchain is entered and entered. The child's information can quickly match the missing child information in the system, and it will not be easier to solve the problem. At present, Microsoft, Superbooks, and the United Nations have joined the blockchain identity project, which has improved efficiency and enhanced security in the post-Internet authentication, and has taken an important step in proving citizenship and combating human trafficking. Charities look to blockchain Some time ago, "Binghua Boy" became popular in the network. Netizens donated more than 300,000 yuan for it. However, it is reported that only 500 yuan was reached in the hands of the "ice boy". The netizens were angry, although the relevant agencies explained that the money was It is used to help other children like the "ice boy", but the netizens still continue to doubt the sound, and even began to be disheartened about the domestic charity. If the blockchain technique is used in the above case, will the result be different? The transparency of the blockchain and its "hard", which can not be falsified, can be said to be a "righteous" account. Every transaction after the charity receives the money is automatically recorded on the ledger. The records of the transactions are also completely open and transparent. The unique decentralization of the blockchain determines that no one can change the records, which means that every transaction is trustworthy. In addition, the distributed nature allows everyone to track down the whereabouts of each good, and once they find unreasonable expenses, they can make corresponding moves. In this way, netizens can always pay attention to the whereabouts of every money donated to the "ice boy." Indeed, some institutions are playing the banner of charity and secretly doing things that are mad and mad. This kind of phenomenon is too numerous to enumerate. Charity incidents are not just domestic specialties. In 2012, then UN Secretary-General Ban Ki-moon stated that 30% of UN development aid failed due to corruption. When blockchain technology is used in philanthropy, when all transactions become traceable, you can ensure that every dollar spent on the donor is used, which will bring more benefits to charity. Favorable impact. Blockchain pricing for content Do you have such an experience? I saw an article with a lot of praise, but when I opened it, it was an article of little value. After all, this is a world that is easy to praise, but in this way, it is very likely that the other high-quality text will be overwhelmed, and it will not be worth the candle. I have to admit that due to the rapid development of the Internet, we have a lot of information about the times, and sometimes it is difficult to find the precise information we need. then what should we do? This problem can be partially solved by using the blockchain. UGC Network proposes to make truly valuable content stand out. Blockchain technology can be used to create a content pricing market that allows users to price content by voting. The operation principle is particularly simple. When a certain content appears in front of the user, it is clearly priced. If you think that its price is lower than its own value, the user can praise it as its appreciation, and the price of the content after the praise becomes Original price + voting cost. If the user Buddha likes it? This also includes incentives, that is, users like to pay for it, part of the cost is given to the author, and part of the cost is distributed to users who have previously praised it. This is similar to a predictive activity in which a user predicts and receives a reward. If the user fails to predict and the content he likes is only his own, then he has to pay for it (the cost of the praise). In general, an article worth 1 buck must be lower than an article worth 100 bucks, but a 100-pound article is not necessarily better than a 50-pound article, when paid-for-pay and paid points are implemented. After praise, it will reduce the behavior of many Buddhist praises to a certain extent, and it can also solve the situation of false news and low-quality news flooding. Our life is a long and complicated TV series. Sometimes we can't change the story that has already been filmed, but the healthy development of blockchain technology will hopefully change our future story, so that we don't have to repeat the same mistakes in place. Please stay tuned.
