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.
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，是一种用于确保正常社会和经济活动的大规模复杂装置或系统。由于数据收集困难、项目周期长、数据复杂、安全性差、可追溯性和数据交互困难等问题，大多数国家基础设施的档案管理仍处于信息时代之前。为了解决这些问题，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。该架构通过传感器和其他物联网设备实时收集国家基础设施建设数据，根据特定业务流程将异类数据源数据转换为统一格式，并及时将数据存储在区块链中，以确保数据的安全性和持久性。通过联邦学习对存储在链上的数据和来自多个地区或领域的数据进行知识提取，并联合建模。将参数和结果存储在链上，并共享每个节点的信息，以解决数据交互的问题。
