摘要:

区块链是一种分布式账本技术,依靠智能合约等逻辑控制功能演变为完整的存储系统。其分类方式、服务模式和应用需求的变化导致核心技术形态的多样性发展。为了完整地认知区块链生态系统,设计了一个层次化的区块链技术体系结构,进一步深入剖析区块链每层结构的基本原理、技术关联以及研究进展,系统归纳典型区块链项目的技术选型和特点,最后给出智慧城市、工业互联网等区块链前沿应用方向,提出区块链技术挑战与研究展望。

Abstract:

Blockchain is a kind of distributed ledger technology that upgrades to a complete storage system by adding logic control functions such as intelligent contracts.With the changes of its classification,service mode and application requirements,the core technology forms of Blockchain show diversified development.In order to understand the Blockchain ecosystem thoroughly,a hierarchical technology architecture of Blockchain was proposed.Furthermore,each layer of blockchain was analyzed from the perspectives of basic principle,related technologies and research progress in-depth.Moreover,the technology selections and characteristics of typical Blockchain projects were summarized systematically.Finally,some application directions of blockchain frontiers,technology challenges and research prospects including Smart Cities and Industrial Internet were given.

Key words: blockchain, cryptocurrency, decentralization, hierarchical technology architecture, technology diversity
