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, as a result, whether a blockchain registration request sent by a blockchain node in a blockchain relay communication network comprises a set identifier;
• in response to the result being TRUE, registering the blockchain node to a blockchain node set corresponding to the set identifier;
• in response to the result being FALSE, registering the blockchain node to a default blockchain node set comprising all blockchain nodes in the blockchain relay communication network to which the blockchain node pertains;
• determining, in response to receiving a blockchain message to be sent to a target blockchain node set of the blockchain relay communication network, a target blockchain node registered to the target blockchain node set and a target relay node in the blockchain relay communication network;
• and
• transmitting the blockchain message to the target blockchain node through the target relay node.

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, as a result, whether a blockchain registration request sent by a blockchain node in a blockchain relay communication network comprises a set identifier;
• in response to the result being TRUE, registering the blockchain node to a blockchain node set corresponding to the set identifier;
• in response to the result being FALSE, registering the blockchain node to a default blockchain node set comprising all blockchain nodes in the blockchain relay communication network to which the blockchain node pertains;
• determining, in response to receiving a blockchain message to be sent to a target blockchain node set of the blockchain relay communication network, a target blockchain node registered to the target blockchain node set and a target relay node in the blockchain relay communication network;
• and
• transmitting the blockchain message to the target blockchain node through the target relay node.
