摘要:

区块链的本质是一个去中心化的分布式账本系统;物联网是由海量异构终端接入互联而成,具备天然的分布式特征,因此两者结合的物联网区块链被广泛看好。同时,由于物联网感知终端的异构性、计算存储及数据传输能力都受限等特性,使物联网区块链面临较大挑战,其中密码共识技术成为关键问题。在总结当前区块链共识算法的基础上,分析其对物联网区块链的适用性,介绍了几大物联网区块链平台及共识机制应用现状,并阐述了针对物联网区块链的共识机制优化研究进展。最后展望物联网区块链的优化技术,总结有潜力的研究方向。

Abstract:

The essence of the blockchain is a decentralized distributed ledger system.The Internet of things is interconnected by massive heterogeneous terminals and has natural distributed characteristics.Therefore,the combinedIoT blockchain is widely optimistic.At the same time,due to the heterogeneity of the IoT-aware terminal,the limited computing capacity and the ability of data transmission,the IoT blockchain faces great challenges.The password consensus technology has become a key issue.On the basis of summarizing the current blockchain consensus algorithm,its applicability to the IoT blockchain was analyzed,the current application status of several IoT blockchain platforms and consensus mechanisms was introduced,and the optimization research progress of the consensus mechanismin IoT blockchain was described.Finally,the optimization technology of the IoT blockchain and the potential research directions were summarized.

Key words: blockchain, IoT, consensus mechanism, DAG, intelligent enhancement, lightweight password
