【Abstract】National infrastructure is a material engineering facility that provides public services for social production and residents' lives, and a large-scale complex device or system is used to ensure normal social and economic activities. Due to the problems of difficult data collection, long project period, complex data, poor security, difficult traceability and data intercommunication, the archives management of most national infrastructure is still in the pre-information era. To solve these problems, this paper proposes a trusted data storage architecture for national infrastructure based on blockchain. This consists of real-time collection of national infrastructure construction data through sensors and other Internet of Things devices, conversion of heterogeneous data source data into a unified format according to specific business flows, and timely storage of data in the blockchain to ensure data security and persistence. Knowledge extraction of data stored in the chain and the data of multiple regions or fields are jointly modeled through federal learning. The parameters and results are stored in the chain, and the information of each node is shared to solve the problem of data intercommunication.

【摘要】国家基础设施是为社会生产和居民生活提供公共服务的物质工程设施，是用于保障正常社会经济活动的大型复杂装置或系统。由于数据采集难、项目周期长、数据复杂、安全性差、溯源难、数据互通等问题，大部分国家基础设施的档案管理仍处于前信息时代。针对这些问题，本文提出了一种基于区块链的国家基础设施可信数据存储架构。这包括通过传感器等物联网设备实时采集国家基础设施建设数据，根据具体业务流程将异构数据源数据转换为统一格式，并将数据及时存储在区块链中，确保数据安全和安全。坚持。通过联邦学习对存储在链上的数据和多个区域或领域的数据进行知识提取联合建模。参数和结果存储在链上，共享各个节点的信息，解决数据互通问题。
