Methods and apparatuses for transmitting messages

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

• determining, in response to receiving a blockchain message, one or more message priority identifiers of the blockchain message;
• adding the blockchain message to two or more message queues stored in a relay node, each message queue comprising one or more blockchain messages corresponding to a same message priority identifier of the one or more message priority identifiers;
• determining a to-be-transmitted blockchain message from the two or more message queues stored in the relay node in a blockchain relay communication network based on a message transmission policy, the message transmission policy being configured to transmit blockchain messages from relay nodes in the blockchain relay communication network based upon the one or more message priority identifiers identifying one or more target blockchain nodes in the blockchain relay communication network, wherein the one or more message priority identifiers are configured based upon a user configuration instruction and represents a priority of a blockchain message to be transmitted in the blockchain relay communication network;
• generating a routing table for recording a blockchain node set to which each blockchain node pertains and a connection relationship between each blockchain node and the relay nodes, wherein the routing table is in a form of a tree-type routing table;
• obtaining an identifier from the to-be-transmitted blockchain message;
• determining the one or more target blockchain nodes based on the identifier;
• determining a target relay node connected to the one or more target blockchain nodes in the blockchain relay communication network;
• transmitting, based upon the identifier, the to-be-transmitted blockchain message to the one or more target blockchain nodes through the target relay node;
• and
• in response to determining that the relay node is not directly connected to the target relay node:
• determining a transmission path between the relay node and the target relay node;
• and
• sending the to-be-transmitted blockchain message to a relay node at a next hop in the transmission path.

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 one or more operations comprising:
• determining, in response to receiving a blockchain message, one or more message priority identifiers of the blockchain message;
• adding the blockchain message to two or more message queues stored in a relay node, each message queue comprising one or more blockchain messages corresponding to a same message priority identifier of the one or more message priority identifiers;
• determining a to-be-transmitted blockchain message from the two or more message queues stored in the relay node in a blockchain relay communication network based on a message transmission policy, the message transmission policy being configured to transmit blockchain messages from relay nodes in the blockchain relay communication network based upon the one or more message priority identifiers identifying one or more target blockchain nodes in the blockchain relay communication network, wherein the one or more message priority identifiers are configured based upon a user configuration instruction and represents a priority of a blockchain message to be transmitted in the blockchain relay communication network;

• determining a transmission path between the relay node and the target relay node;
• and
• sending the to-be-transmitted blockchain message to a relay node at a next hop in the transmission path.
