Mixed consensus implementation device and implementation method oriented to graph block chain

Abstract

The invention relates to a mixed consensus implementation method for a graphic block chain, and the method at least comprises the steps of calling at least one module to generate a new data block, and broadcasting the new block; calling at least one module to check and verify the received new block based on a preset rule; invoking at least one module to generate an empty block; and calling at least one module to update the committee member list. An existing graphic block chain can only achieve probabilistic consensus, while the hybrid consensus algorithm proposed by the invention achieves deterministic consensus on the graphic block chain for the first time, so that the speed of achieving the consensus by the graphic block chain can be accelerated. According to the invention, generation and consensus of the blocks are decoupled for the first time, and modular design can be carried out on the two parts respectively. According to the invention, a fully decentralized hybrid consensus algorithm is proposed on the graphic block chain for the first time, and many existing graphic block chains such as IOT A, Obyte and the like cannot achieve this.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a hybrid consensus realization device and method for schema block chains. Background technique [0002] In a narrow sense, a blockchain is a special distributed database, which is a chained data structure composed of blocks formed by multiple data organizations in a sequential manner, and is cryptographically guaranteed to have an impossible Tampering and unforgeable properties. Broadly speaking, blockchain technology is a new distributed infrastructure and computing paradigm that uses distributed consensus algorithms and cryptography to realize trusted distributed ledgers. [0003] In any blockchain system, a distributed group of participants needs to reach a consensus on some value, so the blockchain consensus algorithm is the core of all blockchain systems. The working principle of the blockchain is as follows: every once in a while, the system elects a leader ...

Problems solved by technology

[0006] For example, the patent document with the publication number CN112202775B in the prior art proposes a block DAG with a network structure as the bottom layer. The consensus mechanism of the directed acyclic graph of the block transforms the consensus problem in the block DAG into the consensus problem in the blockchain, and uses the consensus mechanism in the mature blockchain to solve the consensus problem in the block DAG
