Characteristics of Blockchain Assets--Global Circulation

　　As we all know, blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The person in charge of blockchain technology research and development of China Enterprise Tongbao said that the so-called consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights between different nodes in the blockchain system.

 

　　Blockchain (Blockchain) is an important concept of Bitcoin, which is essentially a decentralized database and the underlying technology of Bitcoin. A blockchain is a series of data blocks that are associated using cryptographic methods. Each data block contains the information of a Bitcoin network transaction, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

 

　　In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner according to time sequence, and is cryptographically guaranteed to be an untamperable and unforgeable distributed ledger.

 

　　Broadly speaking, blockchain technology utilizes blockchain data structures to verify and store data and utilize distributed nodes.

 

　　Generally speaking, the blockchain system consists of data layer, network layer, consensus layer, incentive layer, contract layer and application layer. Among them, the data layer encapsulates the underlying data blocks and related basic data and basic algorithms such as data encryption and timestamp; the network layer includes distributed networking mechanisms, data dissemination mechanisms and data verification mechanisms; the consensus layer mainly encapsulates network nodes The incentive layer integrates economic factors into the blockchain technology system, mainly including the issuance mechanism and distribution mechanism of economic incentives, etc. The contract layer mainly encapsulates various scripts, algorithms and smart contracts, which is a blockchain The basis of programmable features; the application layer encapsulates various application scenarios and cases of the blockchain. In this model, the timestamp-based chain block structure, the consensus mechanism of distributed nodes, the economic incentives based on consensus computing power, and flexible and programmable smart contracts are the most representative innovations of blockchain technology.
