摘　　要：针对供应链中存在的供应商信息互通难、溯源数据真实性保障难等问题,提出了区块链技术构造供应链溯源方案,打通供应链生态,确保溯源过程中的数据可信;设计了具有记录查询功能的布隆过滤器,在进行溯源查询之前对查询请求进行过滤,检查标识是否合法及是否已被查询过,有效抑制同一标识的滥用,进而一定程度抑制假冒产品猖獗的现状。所设计的布隆过滤器比传统数据库查询以及同类布隆过滤器具有更优秀的时间开销和内存开销;使用SBFT共识算法以及SM2门限签名,可以将通信量降低到O(n),提高上链速率。方案分析结果表明,所提方案比同类方案通信量更低,计算效率更高,存储开销更少。Aiming at the problems existing in the supply chain such as difficulty in supplier information exchange and difficulty in ensuring the authenticity of traceability data,this paper proposes blockchain technology to construct supply chain traceability scheme to open up the supply chain ecology and ensure the credibility of data in the traceability process.A bloom filter with record query function is designed to filter query requests before tracing and check whether the identifier is legal and has been queried,effectively suppressing the abuse of the same identifier,thus to a certain extent suppressing the rampant situation of counterfeit products.The designed bloom filter has better time and memory overhead than traditional database queries and similar bloom filters.Using SBFT consensus algorithm and SM2 threshold signature,the communication traffic can be reduced to O(n)and the uplink rate can be increased.The results of scheme analysis show that the proposed scheme has lower communication volume,higher computational efficiency and less storage overhead than similar schemes.
