An Improved Scheme of Proof-of-Stake Consensus Mechanism

Blockchain is a distributed system with decentralized, tamper-proof, traceability and other characteristics. The primary function of a distributed system is to enable consensus among nodes without trust. It is especially important to choose the appropriate consensus mechanism to improve the performance of the blockchain. Based on the original Proof of Stake (PoS), this paper introduces behavioral credits, establishes credit ratings, and interacts with the currency age in the PoS mechanism. By this way, it makes the revenue distribution of the nodes participating in the generation of the PoS mechanism more fair and reasonable, improves social stratification and resists the trend of system centralization.
