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 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; The proxy node is responsible for packaging the transaction information on the blockchain network to generate a system block; the proxy node verifies the generated system block, and if the verification fails, the proxy node responsible for generating the system block is eliminated; If the verification is passed, the current proxy node will receive rewards and continue to generate system blocks until the end of the current polling cycle; judge whether it is necessary to re-select the proxy node, if necessary, re-select the proxy node through election, otherwise proceed to the next cycle polling. The invention introduces an election scheme and adopts a credit evaluation mechanism; it can reduce the risk of block chain bifurcation, so as to achieve the purpose of safe and efficient data sharing.
Description
technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain consensus method, and in particular to an improved efficient consensus method, system, computer equipment and storage medium. Background technique [0002] Blockchain technology is a technology that effectively solves the problem of multi-party cooperation and trust. It is different from traditional technologies. It uses a distributed accounting method to store data. Characteristics 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 for blockchain technology to solve the problem of how to reach consensus in a completely free and open network that lacks trust. In order to make the blockchain applicable to a wider range of fields, various consensus mechanisms, such as PoW (Proof of Work), PoS (based on Proof of Stake) and DPoS (based on Authorized P...
