Member management method and device of block chain, electronic equipment and computer readable medium

The invention discloses a member management method and device of a block chain, electronic equipment and a computer readable medium, and belongs to the field of block chains. The member management method of the block chain comprises the following steps: a member node reports member information to a global cataloguing node; the global cataloguing node audits the member information; the global cataloguing node synchronizes the member information in a global cataloguing cluster and updates a global cataloguing table; and the global catalogue cluster issues the updated global catalogue table to the member node. Maintenance of global catalogues is realized through a global catalogue cluster by adopting a second-level architecture, and global member information synchronization of a large-scale block chain system is quickly realized. 本申请公开一种区块链的成员管理方法及装置、电子设备及计算机可读介质，属于区块链领域。一种区块链的成员管理方法，包括：成员节点向全局编目节点上报成员信息；所述全局编目节点审核所述成员信息；所述全局编目节点在全局编目集群内同步所述成员信息并更新全局编目表；所述全局编目集群向所述成员节点下发更新后的全局编目表。采用二级架构通过全局编目集群实现全局编目的维护，快速实现大规模区
