Claim 7:
8. A non-transitory computer readable storage medium, applied to a blockchain system with memory or hardware processor, characterized in that the non-transitory computer readable storage medium stores a computer program, the computer program includes program instructions, and when executed by a processor, the program instructions enable the processor to execute the following operation:
determining a shared information of a first local area chain, wherein the shared information comprises an internal shared information and an external shared information;
screening out the external shared information from the shared information; and
synchronizing the external shared information to master nodes, except a first master node, in M master nodes, so that the external shared information is shared with local area chains where the master nodes, except the first master node, in the M master nodes are located in N local area chains,
wherein the blockchain system with memory or hardware processor comprises N local area chains and M master nodes, N is an integer greater than or equal to 2, M is an integer greater than or equal to 1, the first local area chain includes at least one child node and the first master node, both connection between the at least one child node and connection between the at least one child node and the first master node are established, the first local area chain is any one of the N local area chains, the first master node is one of the M master node;
an internal shared information of the first local area chain is shared between the at least one child node, and an external shared information of the first local area chain is shared with other local area chains in the N local area chains through the first master node and other master nodes in the M master nodes;
when M is greater than or equal to 2 and M is equal to N, each of the N local area chains includes one master node, the master nodes included in the local area chains are different, and the external shared information of the first local area chain is shared with a second local area chain through the first master node and a second master node included in the second local area chain, wherein
the second local area chain is any one of the N local area chains except the first local area chain, and the second master node is one of the M master nodes except the first master node.
