Block chain network body translation
We need to establish data layer, network layer, consensus layer, incentive layer, contract layer and application layer
1. The data layer encapsulates the underlying data blocks and related basic data and algorithms such as data encryption and time stamp
2. The network layer includes distributed networking mechanism, data transmission mechanism and data verification mechanism
The consensus layer mainly encapsulates all kinds of consensus algorithms of network nodes The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuing mechanism and distribution mechanism of economic incentives5. The contract layer mainly encapsulates all kinds of scripts, algorithms and smart contracts, which is the basis of the programmable characteristics of blockchain
6. The application layer encapsulates various application scenarios and cases of blockchain
, general secretary of the CPC Central Committee, stressed in the eighteenth collective learning of the Central Political Bureau, "block chain as an important breakthrough in core technology and independent innovation", "accelerating the development of block chain technology and instrial innovation". <

the forward-looking judgment of the CPC Central Committee has brought the "blockchain" into the public view and become the common focus of financial capital, real economy and public opinion
from network power to big data, from media integration to blockchain, the Politburo of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, showing the direction, foresight and foresight of the CPC Central Committee, leading the pace of China's instrial change and economic transformation. This collective study of the Political Bureau of the Central Committee of the CPC, with special emphasis on "blockchain", has opened up an imaginary space for the development and application of blockchain
from the perspective of science and technology, blockchain involves many scientific and technological issues such as mathematics, cryptography, Internet and computer programming. From the perspective of application, in short, blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent
these features ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the fact that blockchain can solve the problem of information asymmetry, and realize the cooperative trust and concerted action among multiple agents

blockchain has the ability to innovate trade, transaction and business processes
the two basic concepts supporting blockchain are "business network" and "account book" -- it is thanks to these two concepts that blockchain can become a wise and unchangeable way of trade, transaction and business process execution
network members exchange various assets through an account book that can be accessed by all members. When the network synchronizes the account book, all members need to confirm the transaction of tangible or intangible assets. This shared view helps to establish legitimacy and transparency, even when the parties are not familiar with each other
blockchain can improve visibility and trust in business
by providing visibility to all participants, blockchain can rece transaction settlement time from days or weeks to seconds. The technology can also eliminate the intermediate third party that is usually needed to verify transactions in the past, so as to rece the excessive cost
because blockchain is built on the concept of trust, it can help enterprises rece the risk of illegal behavior on the payment network, thus helping to rece fraud and cyber crime
speed, cost, efficiency and transparency are the most important advantages of blockchain within enterprises and in the company ecosystem where trade activities are carried out. It is precisely because of such advantages that far sighted enterprises are more looking forward to using blockchain technology to innovate infrastructure and better carry out business
the value of blockchain development lies in the growth of the ecosystem
as a business network, blockchain can accommodate a variety of different types of participants. According to the number of participants in the blockchain network, the value of the assets exchanged, and the need to authorize members with different credentials, the adopters of blockchain technology should pay attention to the differences between "licensed" and "unlicensed" blockchain networks
when these business networks continue to expand, the real value of blockchain will be realized. With a strong ecosystem, business networks can reach critical scale more easily, enabling users to build new business models and innovate transaction processes.
1 - public blockchain: it refers to the blockchain that anyone can read and send transactions for validity confirmation, and anyone can participate in its consensus process, so as to jointly maintain the security, transparency and non tampering of public blockchain data
2-community blockchain: also known as alliance chain, it means that the nodes participating in the blockchain are selected in advance, and there are usually good network connections and other cooperative relationships between the nodes
3-private blockchain: the participating nodes only have a limited range, the access and use of data have strict permission management, the write permission is only in the hands of the participants, and the read permission can be opened to the outside world.
