Problems solved by technology
PBFT can greatly improve the consensus performance of the consortium blockchain. However, in a network with N nodes, the algorithm has a consensus protocol and a checkpoint protocol that requires a complexity of O(n 2 ) network information transmission, the network overhead will also increase significantly
Due to communication complexity, the performance of the PBFT protocol will drop significantly when the number exceeds a certain number, and the system performance of the PBFT algorithm blockchain is not ideal in the consortium chain with a large number of nodes

The invention relates to the technical field of block chains, in particular to a block chain consensus method, and specifically relates to an improved efficient consensus method and system, computer equipment and a storage medium. The method comprises the steps that an agent node is selected in an election mode, a polling period is started, and the agent node is responsible for packaging transaction information on a block chain network to generate a system block; the agent node verifies the generated system block;if the verification fails, the agent node responsible for generating the system block is removed; if the verification is passed, the current agent node gets the reward and continues to generate the system block until the current polling period is finished; whether the proxy node needs to be reselected or not is judge; if so, the proxy node is selectedagain in an election mode; otherwise, polling of the next period is carried out. An election scheme is introduced, and a creditevaluation mechanism is adopted; the risk of block chain bifurcation can be reduced, so that the purpose of safely and efficiently performing data sharing is achieved.
Description
technical field [0001] The present invention relates to the technical field of block chains, in particular to block chain consensus methods, and in particular to an improved efficient consensus method, system, computer equipment and storage media. Background technique [0002] Blockchain technology is a technology that effectively solves the trust problem of multi-party collaboration. It is different from traditional technology and uses distributed bookkeeping to store data. Features of a reliable database. The consensus mechanism in the blockchain is one of the most critical technologies. An efficient consensus mechanism is the core element of the blockchain technology to solve the problem of how to reach a consensus in a completely free and open network that lacks trust. In order to make the blockchain applicable to a wider range of fields, PoW (proof of work), PoS (based on equity proof) and DPoS (based on authorized equity proof) and other consensus mechanisms suitable ...
