How to make blockchain open and transparent

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

5. 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

Seeing some answers to the debate on the definition of blockchain, I suddenly realize that my answer to this explanation principle has always been directed at bitcoin. There is no specific and unique answer in the instry between the definition of blockchain. Here I first summarize the characteristics of "blockchain" according to the papers I read:

1; Hash chain & quot There are several nodes participating in the system operation (distributed)

3. Reach a consensus on the consistency of basic data (consensus agreement / algorithm) through a certain protocol or algorithm

since bitcoin is currently one of the most typical and influential applications of blockchain, it will be much easier to understand how bitcoin uses blockchain before understanding other forms of blockchain applications

1. see where food comes from

2. buy local procts in a more flexible way

3. how food on your table is delivered from farms or by sea

4. incentive schemes across traditional boundaries

5. emerging markets for innovative trading

6. figure out what your food is all about, It's really important
