Blockchain is more powerful than Internet

1. Block chain 3 architecture block chain 3 is mainly used in the field of social governance, including identity authentication, notarization, arbitration, auditing, domain name, logistics, Internet of things medical guards. For example, today's latest news, Ma Huateng pointed out at the 2018 China Internet plus digital economic summit held today, Tencent will use the block chain technology to cooperate with hospitals to prescribe digital prescriptions. In addition, wechat is also launching innovative medical services such as digital medical insurance card in many places.

2.

Because the design of blockchain is a kind of protection measure, such as distributed computing system with high fault tolerance. Blockchain makes hybrid consistency possible. This makes blockchain suitable for recording events, titles, medical records and other activities that need to include data, identity management, transaction process management and provenance management. Blockchain has great potential for financial disintermediation and has great influence on guiding Global trade

extended data :

1. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system

2. Blockchain is an important concept of bitcoin, which is essentially a disintermediated database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

3. Blockchain - the original blockchain is a kind of decentralized database, which contains a list called blocks, with continuously growing and orderly records. Each block contains a time stamp and a link with the previous block. The block chain is designed so that the data can not be tampered with. Once recorded, the data in a block will be irreversible

3. In the traditional Internet era, the architecture of trust system relies on long-term accumulation and a lot of cost. The birth of jinwowo network technology blockchain + big data technology builds a lowest cost trust mode with code. Blockchain only needs to execute code to achieve real, whole process and tamperable data records, and these big data are the most valuable assets of the Internet era.

4. In essence, blockchain is a decentralized ledger system, which has the characteristics of decentralization, openness, non tampering information and programmability. It can be used as the underlying storage and transmission protocol of value Internet. Blockchain is expected to lead us from personal trust and institutional trust to the era of machine trust. Consensus mechanism is the core of regional chain construction. digital currency is just the beginning. Blockchain can change more, reshape the world's trust system, and solve many problems of high trust cost in the past
there is a core difference between blockchain and Internet: the value of underlying protocols and upper applications of blockchain and Internet are completely reversed. It mainly comes from the two core features of blockchain:

the first feature is that zero knowledge proof changes the ownership of data. In other words, the user's personal data on the blockchain belongs to the user and does not need to be provided to the application and stored on the central server. Then the core support "data" behind the market value of Internet application layer services, such as bat, will lose its original value in the field of blockchain
another feature is the economic incentive model brought by token, which gives high value to the underlying protocol. In the Internet era, no one pays for HTTP protocol, no one pays for sending and receiving email, and no one pays for Google's search service.

5. Generally speaking, blockchain is an "encrypted distributed synchronous updating accounting technology"
characteristics of blockchain:
the core potential of blockchain lies in the transparency, openness, traceability and non tampering of information
origin of blockchain:
blockchain technology originated from a special currency, and its essence is to create a decentralized monetary system
it's hard to say whether we can change the world in the future, but the future is very clear.

6. It seems that there is no such kind of list in the wallet list, but if you ask which digital currency wallet can be used to store money, and then you can directly register the bill in the wallet, then the wallet developed by the road printing agreement is very good.

7. In a sense, mutual fund is a business instry, and blockchain is a technology. Can we put it another way? Is there any advantage over pawnbroking over computerized accounting? Then, from the perspective of relevance, blockchain must be combined with instry scenarios. The characteristics of blockchain storage determine that it can be organically combined with Internet Finance and banking, such as transfer record tracing, data query record, etc. you will find that although blockchain technology is decentralized, if the roles in the instry are recognized to join a blockchain, Then this blockchain graally loses the significance of zhongjinhua. As many instry internet platforms say, there is no middleman to earn the price difference, and the platform is even the middleman. If you prefer technology, the social market in the current window period of blockchain is good. In the Guangmao application scenario, Hujin is just one. If you focus on the financial instry business, blockchain will serve as a more meaningful tool for you

8. There is no substitute. At present, it is more icing on the cake. In the future, it may be a basic framework and a core operation. For example, the application platform of SMIC blockchain public service platform in Changsha is a good example. Internet technology is the support of the underlying framework, and blockchain technology is the core of the platform.

9. Credit problem of central system
huge rendant account books and maintenance cost
issue of currency
the earliest currency was precious metal gold and silver. Due to the inconvenience of use, symbolic currency was invented to describe gold and silver (how much gold and silver is printed and how many banknotes are printed), and then the financial crisis made people completely symbolize and credit currency, which was also separated from gold and silver, Only credit currency is used to participate in transactions
up to now, credit currency has been electronic (I say this because it is essentially the continuation of paper currency, which can not be called digital currency), and the daily huge transaction data is completed by computer.
some geeks believe that the issuance right of currency is centralized in the center (gov), so if the gov wants to issue additional money, it will issue additional money, To put it more simply, if you want everyone to pay taxes, you have to pay taxes. You don't have to tell me
therefore, the currency backed by government credit may also go bankrupt (referring to the currency of the Republic of China, to put it bluntly, the reliability of social elites and dignitaries can only guarantee the rights of the common people if they actively meet their priorities in peacetime)
in this case, to protect basic economic activities, people have two choices: to go back to the previous trading methods, such as gold and silver or barter, and choose a decentralized monetary system. Bitcoin provides the second choice
blockchain can not only solve the above problems at one time,
it can also replace the existing technical solutions of banking instry with blockchain technology to rece costs
cost rection is not the most important thing. It mainly solves the issue of currency. I don't know if I will look up the water meter if I write too much detail, so I won't write it...
