Blockchain Data Snapshot Generation and High-speed Retrieval Algorithm for Traceability System
摘要
Abstract
Rapid traceability of food safety is an important means to reduce food hazards.Current research on this issue still cannot meet the demand for high-speed and accurate traceability.In this paper,traditional database technology and new blockchain technology were combined to establish structural data of blockchain snapshots,which not only maintained the data security characteristics of blockchain but also utilized the technical framework of relational databases for high-speed retrieval,it improved the performance of querying blockchain data by 2 to 10 times.A million-level commodity data was selected for simulation and performance evaluation.The experimental results showed the rationality and feasibility of snapshot technology and high-speed retrieval algorithms.关键词
