摘要/Abstract

摘要： 近年来,随着数字加密货币逐步走进人们的视野,其底层的区块链技术也引起了研究者的高度重视。区块链作为一种分布式账本技术,具有多方维护、不可篡改、公开透明等特点。首先,将区块链结构按层级进行划分,从低到高介绍了每层的作用和原理,根据开放程度将区块链分为公有链、联盟链、私有链,以比特币、Hyperledger Fabric为例分析了公有链和联盟链的工作机理。其次,对区块链的底层核心技术共识算法、智能合约、隐私安全做了详细阐述。最后,分析了区块链的研究进展并进行了展望。

关键词: 共识算法, 区块链, 数字加密货币, 隐私保护, 智能合约

Abstract: In recent years,as digital cryptocurrency has gradually come into people's sight,its underlying technology blockchain has also attracted people's attention.As a distributed ledger technology,blockchain is characterized by multi-party maintenance,non-tampering,openness and transparency.In this paper,the structure of block chain is divided according to the hierarchy,and the functions and principles of each layer are introduced from low to high.Block chain is divided into public chain,alliance chain and private chain according to the degree of openness.The working principle of public chain and alliance chain is illustrated by taking Bitcoin and Hyperledger Fabric as examples.And this paper gives a detailed introduction to the underlying core technology consensus algorithm,smart contract and privacy security of blockchain,and analyzes the research progress and research prospect of blockchain in the end.

Key words: Blockchain, Consensus algorithms, Digital cryptocurrency, Privacy protect, Smart contract
