摘要: 物联网( IoT)正在改变人们现有的生活方式,并带来巨大的经济利益。然而,数据的安全性不足和信 任危机限制了物联网的发展。区块链( blockchain)作为一种能够实现数据防篡改的分布式数据存储服务,具有 解决物联网中现有的安全性、数据完整性和可靠性问题的潜力。区块链技术在物联网中的应用面临许多挑战,包 括物联网系统中海量物联网设备、低下的设备计算能力以及无线链路的带宽限制和不可靠传输等特性。这些挑战 都会对物联网环境下区块链的一致性和容量产生重大影响。对现有的分布式网络一致性和容量均衡理论进行了调 研,讨论了现有理论的不足对区块链在物联网中应用的限制,并指出了未来物联网区块链在确保数据一致性的同 时容量优化的研究方向。

Abstract: The Internet of Things (IoT) is poised to transform people’s lives and unleash enormous economic benefit. However, inadequate data security and trust of current IoT are seriously limiting its adoption. Blockchain, a distributed and tamper-resistant ledger, has the potential to resolve the myriad of security, data integrity and reliability concerns in IoT. Integrating blockchain technology into IoT has many challenges, including massive IoT devices, limited computing power, low bandwidth and error-prone radio links, which can have significant impact on the consistency and capacity of the blockchain based IoT. After survey existing theories on consistency and capacity in distributed networks, blockchain-based IoT security architectures is discussed, and future directions in optimally leveraging consistency and capacity of blockchain for IoT applications is pointed out with a review of relevant theories.
