Problems solved by technology

However, this also brings new problems. The more tokens people have, the more likely they are to obtain the right to generate blocks, so as to get block rewards. This will form a vicious circle, which is not conducive to the long-term fairness of the system and stability, and the PoS consensus will eventually compete for bookkeeping rights through hash operations

Abstract

The invention discloses a POVT consensus algorithm based on a voting and credit mechanism, and the POVT consensus algorithm based on the voting and credit mechanism selects block nodes more fairly by introducing the voting mechanism, thoroughly avoids the computing power competition between the nodes, and can ensure the reliability of the nodes participating in the consensus through the introduced credit mechanism. Meanwhile, the influence of rights and interests on bookkeeping right distribution is reduced, so that the difficulty of initiating rights and interests crushing attacks, selfish mining attacks and the like to the system is increased.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a POVT (Proof of Vote and Trust) consensus algorithm based on a voting and credit mechanism. Background technique [0002] As a distributed database, the most basic and core requirement of the blockchain is that all nodes can reach a consensus on the stored data, so the consensus mechanism has always been the focus of research. [0003] Currently, commonly used consensus algorithms in blockchain technology include PoW (Proof of Work), PoS (Proof of Stake) and PBFT (Practical Byzantine Fault Tolerance). Among them, compared with the PoW consensus, the PoS consensus reduces the difficulty of mining by investing equity. The more equity invested, the lower the difficulty of mining. This method considers that the more people who hold tokens, the more they want to maintain The stability of the system, so that its interests will not be damaged. However, this also brings new...
