Problems solved by technology
Due to network failure, equipment failure or other reasons, the consensus state among the various node devices participating in the consensus in the blockchain system may not be consistent, but these node devices do not synchronize the consensus state, which is not conducive to the consensus process It is also not conducive to the realization of the consistency of distributed ledgers among the various node devices in the blockchain system, which affects the stability of the overall performance of the blockchain system

The embodiment of this application provides a method for synchronizing the consensus state of a blockchain system and related equipment, wherein the blockchain system includes a blockchain and a consensus committee, and the consensus committee includes a plurality of node devices participating in the consensus. The method is implemented by the first Executed by a node device, the first node device is any node device in the consensus committee, the method includes: obtaining the first consensus state of the first node device and the second consensus state of the second node device, the second node device is the consensus Any node device in the committee except the first node device; obtain the difference between the first consensus state and the second consensus state, and obtain the synchronization method corresponding to the difference; execute the synchronization operation according to the synchronization method corresponding to the difference, so as to be consistent with The second node device performs state synchronization. The embodiment of the present application can maintain the synchronization of the consensus state among the various node devices of the consensus committee, so as to ensure the stability of the overall performance of the blockchain system.
Description
technical field [0001] This application relates to the technical field of block chain, and in particular to a method for synchronizing the consensus state of the block chain system, a synchronization device for the consensus state of the block chain system, a device for synchronizing the consensus state of the block chain system, and A computer storage medium. Background technique [0002] The blockchain system is a distributed system, and the consensus mechanism is the basis for ensuring the normal operation of the blockchain system. The so-called consensus means reaching a consensus; each node device in the blockchain system stores a distributed ledger (block chain); the consensus process of the blockchain system is to make the distributed The process of keeping the ledger consistent. The consensus process of the blockchain system is usually implemented based on a consensus algorithm, which may include but not limited to: BFT (Byzantine Fault Tolerance, Byzantine Fault T...
