摘 要:区块链作为分布式数据存储、点对点传输、共识机制和加密算法等技术的集成应用,近年来已成社会研究讨论的热点。区块链仍处于发展阶段,还存在很多的技术难点,例如数据并发量低、扩展性较差和各链之间无法兼容等,因此如何有效防范这些风险,是急需解决的问题。目前,国家正在提倡加快推进政务数据共享交换,也在为区块链落地应用做试点和探索。因此,论文提出了公链和联盟链的选型关键问题,以及对于效率与共识、隐私与透明、分散与集中的综合权衡考虑的分析和建议。同时,分析了区块链的难点和对应最新的研究成果及技术,还分析了区块链产业发展的风险与防范思路。

Abstract: As an integrated application of distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm. Blockchain has become a hot topic in social research in recent years. In the early Etages of Blockchain development, it faces various difficulties of which the low concurrency, poor scalability, and incompatibility between various chains, etc. How to effectively prevent these risks is an urgent problem to be solved. At present, the state is advocating the acceleration of public data exchange and share , and is also piloting and exploring the application landing of blockchain.
This paper advances the key problem that in the selection of the public chain and consortium chain, and analyzes and recommends comprehensive and balanced considerations of efficiency and consensus, privacy and transparency, and decentralization and concentration. Meanwhile we analyze the difficulties of blockchain as well as the latest research results and technologies. It also analyzes the risks and precautions in the blockchain industry.
Key words: blockchain; public blockchain; consortium blockchain; consensus mechanism; risk; selection
1 引言
区块链作为一种新兴的互联网技术,将对政务服务模式及数字经济带来有想象力的影响。区块链技术本身的公开、透明、可验证的技术特质,带来的新型模式,能够推动政务和商业服务模式的转变,促进互联网从信息互联网向可信互联网乃至价值互联网的转变。另一方面,区块链技术本身的并发性、安全体系、兼容性等也面临一系列挑战,B端机构在实施区块链落地项目中面临技术选型问题,场景设计需要和区块链技术发展保持适配性,同时要考虑到现阶段的技术应用风险,加强对这一新兴技术应用的监管。
2 背景
区块链作为分布式数据存储、点对点传输、共识机制和加密算法等技术的集成应用,近年来已成许多国家政府和机构研究讨论的热点。……
