Blockchain System, Information Sharing Method and Related Equipment

An information sharing method, applied to a blockchain system, wherein the blockchain system 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, a first local area chain includes at least one child node and a 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 nodes, and the method comprises:

• determining a shared information of the first local area chain by the first master node, wherein the shared information comprises an internal shared information and an external shared information;
• screening out the external shared information from the shared information by the first master node;
• and
• synchronizing the external shared information to the master nodes, except the first master node, in the M master nodes by the first master node so that the external shared information is shared with the local area chains where the master nodes, except the first master node, in the M master nodes are located in the N local area chains.

An information sharing device, applied to a blockchain system, wherein the blockchain system 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, a first local area chain includes at least one child node and a 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 nodes, and the device comprises:

• a determining unit, used for determining a shared information of the first local area chain, wherein the shared information comprises an internal shared information and an external shared information;
• a screening unit, used for screening out the external shared information from the shared information;
• and
• a synchronizing unit, used for synchronizing the external shared information to the master nodes, except the first master node, in the M master nodes so that the external shared information is shared with the local area chains where the master nodes, except the first master node, in the M master nodes are located in the N local area chains.

A computer readable storage medium, applied to a blockchain system, characterized in that the 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 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.
