Consensus result synchronization across algorithms of different fault tolerance types

A blockchain consensus apparatus, comprising:

• processing circuitry configured to
• broadcast consensus requests to at least two blockchain nodes executing consensus algorithms of different fault tolerance types in a blockchain network, the consensus algorithms of different fault tolerance types comprising a first consensus algorithm and a second consensus algorithm;
• obtain response messages from blockchain nodes in the blockchain network in response to the consensus requests;
• count a node quantity of blockchain nodes transmitting the response messages in a same consensus stage, the node quantity comprising a quantity of the at least two blockchain nodes executing the consensus algorithms of different fault tolerance types;
• and
• when the node quantity satisfies a consensus condition of the first consensus algorithm and does not satisfy a consensus condition of the second consensus algorithm, reach a consensus on a blockchain node executing the first consensus algorithm, and synchronize a consensus result of the first consensus algorithm with a blockchain node executing the second consensus algorithm such that the blockchain node executing the second consensus algorithm reaches a consensus.

• obtaining response messages from blockchain nodes in the blockchain network in response to the consensus requests;
• counting a node quantity of blockchain nodes transmitting the response messages in a same consensus stage, the node quantity comprising a quantity of the at least two blockchain nodes executing the consensus algorithms of different fault tolerance types;
• and
• when the node quantity satisfies a consensus condition of the first consensus algorithm and does not satisfy a consensus condition of the second consensus algorithm, reaching a consensus on a blockchain node executing the first consensus algorithm, and synchronizing a consensus result of the first consensus algorithm with a blockchain node executing the second consensus algorithm such that the blockchain node executing the second consensus algorithm reaches a consensus.
