Blockchain is enough to subvert the 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. More often, blockchain technology will be attached to the B / s and C / S structure of the Internet to achieve functional expansion, but it is still a supplement to the existing Internet technology. At present, most of the application scenarios of blockchain can be realized with B / s and C / S structure, with higher efficiency and more mature technology
whether from the perspective of information transmission efficiency and resource consumption, or from the perspective of nervous system evolution, blockchain cannot become the mainstream architecture of the Internet, let alone the subversive and revolutionary of the future Internet.

3. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

4. 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.

5. Decentralization is a concept opposite to centralization. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center. On the contrary, in a system with many nodes, each node has a high degree of autonomy, and each node is a "small center"

with the diversification of network service forms, the decentralized network model becomes clearer and more possible. This paper explains the importance of decentralization from the development stage of the Internet, the advantages of decentralization, and the prediction of the trend of decentralization.

6. 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.

7. Blockchain technology will not subvert the philosophy of the Internet. It mainly depends on the development of technology
