Communication method and communication apparatus

A communication method applied to a second communication apparatus, the method comprising:

• receiving a first message from a first communication apparatus, wherein the first message is for requesting to set up data consensus protocol (DCP) initial access, and the first message comprises an identifier of the first communication apparatus and a blockchain identifier;
• sending a second message to the first communication apparatus, wherein the second message indicates a consensus mode set for blockchain communication;
• receiving a third message from the first communication apparatus, wherein the third message indicates first consensus mode information selected by the first communication apparatus from the consensus mode set, wherein the consensus mode set comprises a plurality of different consensus modes each comprising at least a blockchain type and a consensus algorithm;
• and
• sending a fourth message to the first communication apparatus, wherein the fourth message indicates that the DCP initial access succeeds or fails.

A communication apparatus, comprising:

• at least one processor;
• and
• a memory storing a program or instructions that, when executed by the at least one processor, cause the communication apparatus to:
• send a first message to a second communication apparatus, wherein the first message is for requesting to set up data consensus protocol (DCP) initial access, and the first message comprises an identifier of the communication apparatus and a blockchain identifier;
• receive a second message from the second communication apparatus, wherein the second message indicates a consensus mode set for blockchain communication;
• send a third message to the second communication apparatus, wherein the third message indicates first consensus mode information selected by the communication apparatus from the consensus mode set, wherein the consensus mode set comprises a plurality of different consensus modes each comprising at least a blockchain type and a consensus algorithm;
• and
• receive a fourth message from the second communication apparatus, wherein the fourth message indicates that the DCP initial access succeeds or fails.
