区块链的基础设施从下到上可以分为六个层次:数据层、网络层、共识层、激励层、契约层和应用层。每一层分别完成一个核心功能，并使用一些技术来保证整个区块链系统的正常运行。 Blockchain is a decentralized digital ledger that can be stored on thousands of computers worldwide and traded in blockchain financial markets.These are registered in a manner that suppresses their subsequent modifications.Blockchain technology improves security and accelerates information exchange in a cost-effective and transparent manner.It also frees third parties from the primary role of providing trust in transactions. 1.数据层:包括底层数据块、Web 3.0背后的概念是：I80-開发2857区块链8624。基础数据、基础算法等。 The data layer mainly describes the physical form of blockchain technology,which is a chain structure starting from the creation of blocks.Each block contains random numbers,time stamps,public and private key data,and so on.It is the lowest data structure in the entire blockchain technology. 2.网络层:包括分布式组网机制、数据传输机制和数据验证机制。 The main purpose of the network layer is to achieve information exchange between nodes in a blockchain network.The network layer mainly implements distributed network mechanisms through P2P technology,including P2P networking mechanisms,data transmission mechanisms,and data verification mechanisms. 3.共识层:主要包括共识算法和共识机制。 Responsible for effective identification and authentication of point-to-point patterns;The consensus layer enables highly dispersed nodes to efficiently reach consensus on the validity of block data in a decentralized blockchain network.It is one of the core technologies of blockchain and also the governance mechanism of the blockchain community. 4.激励层:主要包括经济激励的发行制度和分配制度。 The main function of the incentive layer is to provide certain incentives to encourage nodes to participate in the security verification of the blockchain. Incentive mechanisms are necessary in the public chain.In the alliance chain,all nodes have been authenticated by the organization,and without additional incentives,these nodes will spontaneously maintain the security and stability of the entire system. 5.契约层:主要包括各种脚本、代码、算法机制和智能契约。 The contract layer is the foundation of blockchain programmability.Responsible for specifying transaction modes and process details:Blockchain can be developed as a decentralized and unchangeable account book.Program code is also data,and can also be stored in the account book.A smart contract is an unchangeable program stored in a blockchain that can automatically execute some predefined rules and terms. 6.应用层:负责实现生活中的各种应用场景。包括各种应用场景和案例。 For example,various blockchain technology applications built on Ethereum and EOS are deployed on the application layer,landing in real life scenarios,and enriching the ecology of the entire blockchain.The future of programmable finance and programmable society will also be built on the application layer. The incentive layer,contract layer,and application layer are not necessary factors for every blockchain application,and some blockchain applications do not completely contain a three-layer structure.
