Problems solved by technology

[0004] However, the verification process of the new block may be malicious; for example, the super node tampers with the transaction information in the newly generated block and sends the newly generated block to the pre-designated verification node for verification. The verification node feeds back the successful verification message to the super node, and then the super node uploads the tampered block to the chain; thus causing the entire blockchain system to crash

Abstract

The invention discloses a DPoS-based consensus method and device, computer equipment and a storage medium. A super node packages transactions in a transaction pool into blocks, and the transaction pool stores transactions generated on a block chain; the super node sends the block to at least one alternative verification node, and one or more alternative verification nodes obtain qualification of the verification node through a workload proof mode; and the super node receives a message of successful verification of the one or more verification nodes, and links the block. The verification node can be determined by using the PoW mode on the basis of the DPoS consensus mechanism, so that the problem that a block node and the verification node in the DPoS consensus mechanism are combined to cause disasters is avoided, and the security of the block chain system is improved.

Description

technical field [0001] This application relates to the technical field of block chain, especially the consensus method, device, computer equipment and storage medium based on DPoS. Background technique [0002] The distributed consensus algorithm is an important technology to ensure the consistency of the system state in the distributed system, and it is an important basis for the distributed file system and the distributed database. The blockchain uses a distributed consensus algorithm to establish the system state in an environment where there is no central node control and there may be damage to the node, thereby establishing trust. [0003] The existing Delegated Proof of Stake consensus mechanism (Delegated Proof of Stake, DPoS) uses proxy voting to select a certain number of super nodes (also known as: block generation nodes) to be responsible for generating blocks; The block is verified, and after the verification is passed, the super node will upload the newly gener...
