BLOCKCHAIN SYSTEM, INFORMATION SHARING METHOD AND RELATED DEVICE

摘要

A blockchain system, an information sharing method and a related device, wherein the blockchain system comprises: N local area chains and M master nodes, where N is an integer greater than or equal to 2, and M is an integer greater than or equal to 1; a first local area chain comprises at least one sub node and a first master node, a connection is established between the at least one sub node and between the at least one sub node and the one master node, the first local area chain is any one of the N local area chains, and the first master node is one of the M master nodes; and internal shared information of the first local area chain is shared between the at least one sub node, and external shared information of the first local area chain is shared with other local area chains among the N local area chains by means of the first master node and other master nodes among the M master nodes, which may ensure reliable communication of information and help reduce the burden of later management and maintenance.
