摘　　要：本文设计并提出了基于国密算法的区块链架构—“国密链”,以国密算法SM2、SM3替换国际通用密码算法的ECC、SHA-256,实现了区块链架构的自主可控.同时,针对当前区块链架构面临的共识算法妥协的现状,设计了“可插拔共识”协议,解决了当前区块链架构面临的共识算法的不可更改的问题.实验结果表明,“国密链”与普通区块链架构在一致性、有效性相近的情况下,拥有更高的共识效率、更低的资源开销.This study designs and proposes a block chain architecture based on the domestic cipher algorithm—“DCchain”,and replaces ECC and SHA-256 of the international general cryptographic algorithm with SM2 and SM3,which realizes the autonomous control of the block chain architecture.At the same time,according to the current status of consensus algorithm compromise faced by block chain architecture,a“pluggable consensus”protocol is designed to solve the unalterable problem of consensus algorithm faced by block chain architecture.Experimental results show that“DCchain”and ordinary block chain architecture have higher consensus efficiency and lower resource cost under the condition of consistency and effectiveness.
