[摘要] 把去中心化、不可篡改和激励机制定义为区块链技术的典型特点,而把可追踪、匿名和可编程定义为区块链技术的功能特性,同时分析了每一个特点和特性的底层支撑技术,以更好地判断区块链项目的真伪及可实现性。在该定义的基础上,分析了物联网(IoT)场景下几个典型的区块链项目,并对其中的一些主要问题和主要方法进行了详细阐述,认为IoT的数据体量和数据安全问题依旧是需要重点考虑的问题。

[Abstract] The decentralization, non-tampering and incentive mechanism are defined as the typical features of blockchain technology, and the traceability, anonymity and programmability are defined as its functional characteristics. Then the underlying supporting technologies of each feature are analyzed to better judge the authenticity and realization of blockchain projects. Further, several typical blockchain projects in the Internet of things (IoT) scenario are analyzed, and main problems and technical methods are described. It is pointed out that the data volume and data security of the IoT are still the key issues to be considered.
