中文摘要: 随着信息产业的发展, 数据生产者产生了大量价值数据. 为了进行数据共享, 赋予数据相应的标识符用于解析数据所在位置,同时为使数据可长期通过标识符访问, 还需保证标识符解析服务长期可用, 但现有标识符系统多数采用半去中心化结构, 由于过于依赖最终解析服务, 其中部分系统由于各种原因逐渐丧失解析能力. 本文基于区块链系统的分布式账本数据一致性, 提出了一种基于区块链的持久标识符系统, 在兼容现有标识符系统访问层的基础上, 提供存储层以保证标识符解析服务持久性及数据的长期正确保存. 基于Handle系统及 Hyperledger Fabric的测试结果表明, 该系统能够在提供可接受的请求响应速度与存储占用率的前提下, 为持久标识符服务提供更好的数据完整 性与解析服务长期可用性.
Abstract:As the information industry develops, data producers have generated great masses of valuable data. Data identifiers are assigned for data sharing to resolve where the data is located. In order to make the data accessible through the identifier for a long time, it is necessary to ensure that the identifier resolution service is available for a long time. Majority existing identifier systems use a semi-decentralized structure, while some of them have gradually lost their resolution capacity due to reliance on the final resolution service. Based on the consistency of distributed ledger data of Blockchain system, this paper proposes a persistent identifier system based on Blockchain. On the basis of compatibility with the access layer of the existing identifier system, a storage layer is provided to ensure the durability of the identifier resolution service and the long-term correct storage of data. Test results based on the Handle system and Hyperledger Fabric show that it can provide better data integrity and long-term availability of resolution service for persistent identifier service under the premise of providing acceptable request response speed and storage occupancy.
