区块链技术的应用前景与挑战:基于信息保真的视角

Opportunities and Challenges of Blockchain Technology:the Perspective of Information Fidelity

本文从发布保真、传播保真、更新保真三方面讨论了信息保真的概念,分析传统互联网技术在信息保真方面所面临的困境。结合比特币的发展,总结了区块链技术相对于传统互联网在数据写入机制、数据存储机制、历史数据维护机制三方面的特点,分析认为区块链可以实现传播保真和一定程度的发布保真,在比特币场景下区块链可以实现更新保真,但在一般使用场景下区块链难以实现更新保真。归纳了目前产业应用区块链技术的实践,结合对区块链技术特点的分析,识别了区块链技术产业应用所面临的机会与挑战。最后,提出区块链技术的发展与应用仍需解决的三大问题:提升区块链交易处理速度、物联网与区块链技术相结合以及区块链管理机制的设计。随着区块链技术以及相关配套技术的发展,区块链技术一定可以得到广泛的应用,并深刻影响和改变人们在互联网上的行为模式和企业之间的合作模式。

This paper analyzed the difficulties of traditional internet in ensuring information fidelity from three perspectives:publication fidelity,transmission fidelity and updating fidelity.Setting Bitcoin as an example,we analyzed the advantage of the blockchain technology over traditional internet in data recording,data storage and data maintenance.Compared with traditional internet,the blockchain technology was advantageous in realizing transmission fidelity and publication fidelity,while its advantage in updating fidelity highly depends on the usage context.We then summarized the use cases of the blockchain technology and identified the opportunities and challenges of its application.Three issues should be resolved before the large scale application:improvement of the transaction processing speed,the coherence of the blockchain with other technologies(e.g.internet of things)and the development of blockchain management protocols.Overall speaking,we thought that the blockchain will eventually coevolve with other technologies,reach wide adoption and fundamentally affect the interaction behavior of individuals and organizations.
