Government affair data processing method and system based on block chain platform

The invention provides a government affair data processing method based on a block chain platform. The government affair data processing method can be applied to the technical field of block chains. The method comprises the following steps: in response to a data uplink request of a service system, authenticating the service system; obtaining first file handling data of the target user; performing encryption processing on the first file handling data to generate second file handling data; generating government affair handling information according to the second handling data and a service system identifier; and calling an intelligent contract to link and store the government affair handling information. The invention further provides a government affair data processing system and device based on the block chain platform, a storage medium and a program product. 本公开提供了一种基于区块链平台的政务数据处理方法，可以应用于区块链技术领域。该方法包括：响应于业务系统的数据上链请求，对所述业务系统进行鉴权；获取目标用户的第一办件数据；对所述第一办件数据进行加密处理生成第二办件数据；根据所述第二办件数据和业务系统标识生成政务办件信息；调用智能合约将所述政务办件信息上链
