基于区块链的供应商信息库去中心化的解决方案

Decentralized solution of supplier information base based on block chain

针对传统供应商信息库集中式的部署模式难以保证数据真伪性和系统安全性问题,构建区块链的异构供应商电子文件存储系统。首先,根据区块链和星际文件系统(IPFS)进行异构数据的分布式存储,由区块链保存小文件,IPFS网络进行异构大文件拆分和分布式存储,提升文件的存储速度;然后,采用区块链智能合约的文件访问控制策略,保证供应商文件管理的安全性和透明度,满足多场景下的文件安全访问。仿真结果表明:系统在保证高效的吞吐性能的同时,又能有效保障链上信息安全性和隐私性。

Aiming at the problem that the centralized deployment mode of traditional supplier information base is difficult to ensure the authenticity of data and system security,a heterogeneous supplier electronic file storage system of blockchain is constructed.Firstly,the distributed storage of heterogeneous data is carried out according to the blockchain and interPlanetary file system(IPFS),the blockchain saves small files,and the IPFS network splits and stores heterogeneous large files,so as to improve the storage speed of files.Then,the file access control strategy of blockchain smart contract is adopted to ensure the security and transparency of supplier file management and meet the file security access in multiple scenarios.The simulation results show that the system can not only ensure efficient throughput performance,but also effectively ensure the information security and privacy on the chain.
