Communication optimization systems of blockchain network, registration methods and message forwarding methods

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• establishing, by a first relay node in a blockchain network, a connection with a first blockchain node in the blockchain network in response to a connection request of the first blockchain node, wherein the blockchain network comprises the first blockchain node and at least one other blockchain node, the first blockchain node and the at least one other blockchain node are peer to peer (P2P) nodes, and after the establishing of the connection with the first blockchain node by the first relay node, the first blockchain node needs only transmit one broadcast message to the first relay node, rather than broadcasting the broadcast message to each of the at least one other blockchain node;
• receiving, by the first relay node, a registration request transmitted by the first blockchain node, wherein the registration request comprises an ID of the first blockchain node and an ID of the first relay node connected to the first blockchain node;
• generating, by the first relay node, a registration event based on the registration request, wherein the registration event comprises the ID of the first blockchain node and the ID of the first relay node connected to the first blockchain node;
• updating, by the first relay node, a local routing table based on the registration event, wherein the local routing table comprises corresponding relationships among the ID of the first relay node and IDs of the at least one other blockchain node in the blockchain network that are connected to the first relay node, and a corresponding relationship between the ID of the first relay node and the ID of the first blockchain node connected to the first relay node;
• and
• forwarding, by the first relay node, a message of the first blockchain node to another relay node or each of the at least one other blockchain node in the blockchain network that is connected to the first relay node based on the corresponding relationships included in the local routing table.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform operations comprising:
• establishing, by a first relay node in a blockchain network, a connection with a first blockchain node in the blockchain network in response to a connection request of the first blockchain node, wherein the blockchain network comprises the first blockchain node and at least one other blockchain node, the first blockchain node and the at least one other blockchain node are peer to peer (P2P) nodes, and after the establishing of the connection with the first blockchain node by the first relay node, the first blockchain node needs only transmit one broadcast message to the first relay node, rather than broadcasting the broadcast message to each of the at least one other blockchain node;
• receiving, by the first relay node, a registration request transmitted by the first blockchain node, wherein the registration request comprises an ID of the first blockchain node and an ID of the first relay node connected to the first blockchain node;
• generating, by the first relay node, a registration event based on the registration request, wherein the registration event comprises the ID of the first blockchain node and the ID of the first relay node connected to the first blockchain node;
• updating, by the first relay node, a local routing table based on the registration event, wherein the local routing table comprises corresponding relationships among the ID of the first relay node and IDs of the at least one other blockchain node in the blockchain network that are connected to the first relay node, and a corresponding relationship between the ID of the first relay node and the ID of the first blockchain node connected to the first relay node;
• and
• forwarding, by the first relay node, a message of the first blockchain node to another relay node or each of the at least one other blockchain node in the blockchain network that is connected to the first relay node based on the corresponding relationships included in the local routing table.
