| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The Proof of Stake (PoS) protocol is one of consensus algorithms for Blockchain, in which the integrity of a new block is validated according to voting by nodes called validators. Due to validator-oriented voting, however, voting results are likely to be false when the number of validators who wrongly vote increases. In the PoS protocol, validators are motivated to vote correctly by reward and penalty mechanism. With this mechanism, validators who contribute to correct consensuses are rewarded, while those who make incorrect block confirmation are penalized. In this paper, we consider a reward-penalty mechanism based on the voting profile of a validator, which is estimated from the voting history of the validator. We evaluate the performance of the proposed mechanism by computer simulation, investigating the impact of system parameters on the estimation accuracy of the validator profile and the amount of validator's stake. Numerical results show that the proposed algorithm can estimate the voting profile of a validator accurately even when the voting profile dynamically changes. It is also shown that the proposed mechanism gives more reward to validators with high voting profile. | |
