Decentralized traceable shared access system

The invention provides a decentralized traceable shared access system. The decentralized traceable shared access system comprises an authentication node and a consensus node, the authentication node is used for managing users, managing document data and services and maintaining data access information based on each functional module deployed on the node; the consensus node is used for performing security management on a user accessing the node based on each function module deployed on the node, initiating a data sharing request and providing a data sharing service according to the data sharing request, the sharing access system is based on the block chain technology, the authenticity and contract execution force of data are ensured, and the sharing access efficiency is improved. Decentralization is realized, and security data management of data sharing is realized. 本发明提供一种去中心化的可追溯共享访问系统，包括：认证节点和共识节点；认证节点用于基于节点上部署的各个功能模块，实现对用户进行管理、对文档数据和业务进行管理并维护数据访问信息；所述共识节点用于基于节点上部署的各个功能模块对访问所述节点的用户进行安全管理、发起数据共享请求并根据数据共享请求提供
