Block generation method, device and blockchain network

A block generation method, wherein the method is applied to a block generation device, and the method comprises:

• obtaining, through a second node device, a signed block issued by a first node device in a blockchain network;
• performing signature verification on the signed block according to public key information;
• performing proof-of-work verification on the signed block after the signature verification succeeds;
• and
• determining whether to add the signed block to a blockchain according to a result of the proof-of-work verification.

A block generation device, wherein the block generation device comprising:

• at least one processor unit, a communication interface, a memory and a communication bus;
• the at least one processor unit, the communication interface, and the memory communicate with each other through the communication bus;
• the memory is configured to store program codes;
• the at least one processor unit is configured to run the program codes to implement the following operations:
• signing a block generated by the block generation device according to private key information built in the block generation device to obtain a signed block;
• and
• issuing the signed block to other node devices through a first node device in the blockchain network.
