Achieve IoT data interconnection based on blockchain and RISC-V

针对物联网特点与痛点,提出以区块链技术为核心、结合物联网技术并运用RISC-V架构实现区块链功能下沉至终端。通过芯片承载区块链的功能使得每一个终端成为区块链的节点,基于区块链的分布式这一特点,满足物联网终端节点功用。通过芯片从源头解决上链数据的可信,针对现有的区块链功能进行轻量化改造,使其符合芯片的硬件特性。通过RISC-V的模块化、高性能、可自定义的指令集实现芯片对于区块链功能的承载。经过合理的分析与例证,能够利用终端作为区块链节点的方式去解决物联网多样化的应用场景,满足安全可信的同时提高性能,降低成本。

Aiming at the characteristics and pain points of the Internet of Things,it is proposed to take the blockchain technology as the core,combine the Internet of Things technology and use the RISC-V architecture to realize the sinking of the blockchain function to the terminal.The function of carrying the blockchain through the chip makes each terminal become a node of the blockchain,and the distributed characteristics of the blockchain are used to meet the terminal node functions of the Internet of Things.The chip is used to solve the credibility of the data on the chain from the source,and the existing blockchain functions are light-weighted to make it conform to the hardware characteristics of the chip.Through RISC-V's modular,high-performance,and customizable instruction set,the chip carries the blockchain function.After reasonable analysis and examples,the terminal can be used as a blockchain node to solve the diversified application scenarios of the Internet of Things,which can improve performance and reduce costs while satisfying security and credibility.
