Abstract:

Most of the supply chain control systems adopt a centralized design,and the system load ceiling is severely constrained by the performance of the central server,resulting in the entire supply chain not flowing properly.Therefore,a scheme combining blockchain,Bitcoin protocol deterministic layered wallet and multi-signature technology is proposed to meet the requirements of product coding,rights management,property transfer,product traceability and anti-counterfeiting verification in the supply chain.The internal entities of the supply chain are divided into "personal entities""product entities" and "right entities",and the entity key is allocated by using the layered wallet technology.The tree structure coding system based on layered wallet technology is given,and the mechanism of decentralized right management and property transfer information recording and verification based on blockchain transaction is designed.Analysis results show that the scheme has the characteristics of blockchain decentralization,transaction traceability and non-tamperability,which can solve common problems in existing technologies and systems,and has greater advantages compared with traditional supply chain control schemes.

摘要:

供应链管控系统多数采用中心化设计,系统负载上限受制于中心服务器性能,导致整条供应链无法正常流动。为此,提出一种结合区块链、比特币协议确定性分层钱包与多重签名技术的方案,以满足供应链中产品编码、权限管理、物权转移、产品溯源和防伪验证等需求。将供应链内部实体分为“人物实体”“产品实体”和“权限实体”,利用分层钱包技术进行实体密钥的分配。给出基于分层钱包技术的树形结构编码体系,并设计基于区块链交易的去中心化权限管控、物权转移信息记录与验证机制。分析结果表明,该方案具有区块链去中心化、交易可回溯和不可篡改等特性,可解决现有技术中的常见的问题,相比传统供应链管控方案有较大的优势。
