面向政府数据开放共享的双链存储模型与案例应用研究

Research on the Dual-chain Storage Model and Case Application for Open Government Data

[目的/意义]盘活政府数据资源,筑牢数据存储基石,充分发挥政府数据要素在经济社会发展中的引擎作用。[方法/过程]面向政府数据开放共享过程构建基于区块链的双链存储模型,通过“链下扩容”的方式拓展区块链系统的存储空间,基于该模型在济南市“泉城链”中的实证分析开展模型的案例应用研究,归纳该研究对其他省市政府数据存储的借鉴与启示。[结果/结论]该模型以“链上服务,链下存储”的运行机制创新了数据存储方式,保障数据安全共享的同时兼顾了海量数据的存储需求,有助于健全政府数据开放共享体系,充分释放数据要素潜能,为其他省市政府数据存储提供参考与思路。

[Purpose/Significance]Activate government data resources,build a solid foundation for data storage,and give full play to the role of government data elements as the engine of economic and social development.[Method/Process]The papaer built a blockchain-based dual-chain storage model for the process of open sharing of government data,expanded the storage space of the blockchain system through“off-chain expansion”,and carried out a case application study of the model based on the empirical analysis of the model in the“Quancheng Chain”of Jinan City,and summarized the reference and inspiration of the research on the data storage of other provinces and municipal governments.[Result/Conclusion]The model innovates the data storage method with the operating mechanism of“on-chain service,off-chain storage”,which guarantees the safe sharing of data while taking into account the storage needs of massive amounts of data,and helps to improve the open government data sharing system,completely unleash the potential of data elements,and provide references and ideas for data storage in other provinces and municipalities.
