摘　　要：区块链是一种随着比特币等加密货币而兴起的一种类似于非关系型的分布式存储数据库,本文利用区块链分布式存储、去信任化和不可篡改的特性设计了一个基于区块链技术的防伪溯源系统(Traceability System Using Public and Private Blockchain,TSPPB)。TSPPB使用公有链和私有链两套区块链,该溯源系统能够确保获得的溯源信息的真实可靠不可篡改并解决传统产品溯源系统存在的产品标签复制、滥发和产品质量问题相关责任人及问题环节定位困难的问题。在确保溯源信息安全性并解决传统溯源系统隐患的同时,TSPPB还能够高效且保持低成本的运行。Blockchain is a non-relational distributed storage database that arises along with bitcoin and other Encryption currency. This paper designs a traceability system based on distributed storage, detrusting and non-tampered characteristics of blockchain. Our traceability system uses two sets of block chain systems, the public chain and the private chain. Our traceability system can ensure that the database of product traceability system can＇t be tampered, solve the problem of product replication, over issue and bind the person responsible to their product quality problem. Our traceability system can ensure the efficient and low cost operation of the traceability system at the same time.
