Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] The embodiment of this application involves blockchain technology. Blockchain is a set of decentralized infrastructure with distributed storage characteristics. Specifically, it is a data structure composed of data blocks in a chronological order similar to a linked list. The data verified in the system, and cryptographically ensure that the data cannot be tampered with and cannot be forged.

Abstract

The embodiment of the invention provides a consensus method of a block chain system and related equipment. The block chain system comprises a block chain and a consensus committee, the consensus committee comprises a plurality of node devices participating in consensus. The method is executed by first node equipment, the first node equipment is any node equipment in the consensus committee, and the method comprises the steps that in the Nth round of consensus process of the block height H of a block chain, whether a block in a locked state exists in a cache space or not is checked, and H and Nare both positive integers; if the block in the locked state exists in the cache space, the block in the locked state is determined as a target block to be consensus; and consensus processing is performed on the target block to obtain a consensus result of the target block in the Nth round of consensus process of the block height H of the block chain. The embodiment of the invention can ensure consensus accuracy.

Description

technical field [0001] The present application relates to the technical field of block chains, and in particular to a consensus method of a block chain system, a consensus device of a block chain system, a consensus device of a 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 Tolerance) algorithm, PBFT (Practical Byzantine Fault Tolerance, Practical Byzantine F...
