区块链具有许多优点，例如去中心化、持久性、匿名性和可审计性。区块链应用范围广泛，从加密货币、金融服务、风险管理、物联网 (IoT) 到公共和社会服务。尽管许多研究集中在区块链技术在各个应用方面的运用，但目前还没有从技术和应用角度对区块链技术进行全面的考察。为了填补这一空白，我们对区块链技术进行了全面的调查。特别是，本文给出了区块链分类，介绍了典型的区块链共识算法，回顾了区块链应用并讨论了技术挑战以及应对挑战的最新进展。此外，本文还指出了区块链技术的未来发展方向。
Blockchain has numerous benefits such as decentralisation, persistency, anonymity and auditability. There is a wide spectrum of blockchain applications ranging from cryptocurrency, financial services, risk management, internet of things (IoT) to public and social services. Although a number of studies focus on using the blockchain technology in various application aspects, there is no comprehensive survey on the blockchain technology in both technological and application perspectives. To fill this gap, we conduct a comprehensive survey on the blockchain technology. In particular, this paper gives the blockchain taxonomy, introduces typical blockchain consensus algorithms, reviews blockchain applications and discusses technical challenges as well as recent advances in tackling the challenges. Moreover, this paper also points out the future directions in the blockchain technology.
