摘要/Abstract

摘要： 区块链技术为刑罚变更执行数据的真实可信提供支撑,并实现各主体间的互信和高效协同.对权威证明共识算法(proof of authority,PoA)存在的制约因素进行分析并提出一种改进的动态加权权威证明算法(dynamic weighted proof of authority,DWPoA),进行刑罚变更执行提请共识.构建联盟链,基于Tangle结构提出一种链上共识算法,进行刑罚变更执行主体间的链上共识;基于(t,n)门限签名提出一种分布式预言机链下共识算法进行链上、链下共识,并对带宽占用率和共识时长进行仿真实验,分布式预言机链下共识算法更具优势.

关键词: 区块链, 共识, 刑罚变更执行

Abstract: Blockchain technology supports the authenticity and trustworthiness of penalty change execution data, enabling mutual trust and efficient collaboration among various entities.To address the constraints of Proof of Authority, an improved Dynamic Weighted Proof of Authority algorithm has been proposed to request consensus for penalty change execution.Another approach to achieve on-chain consensus among penalty change execution entities is to build an alliance chain and propose an on-chain consensus algorithm based on the Tangle structure.Based on the(t, n)threshold signature, a distributed oracle machine offline consensus algorithm has been proposed to carry out the on-chain and off-chain consensus. The bandwidth occupancy and consensus duration have been simulated, and the distributed oracle machine offline consensus algorithm has more advantages.
