Abstract (in Japanese) (See Japanese page) 
(in English) In the blockchain architecture, there are various consensus methods, such as Proof of Work (PoW), Proof of Stake (PoS) and Delegated Proof of Stake (DPoS) for validator selection. A DPoS protocol works similarly to an election, where token holders vote for validator candidates. Elected validators generate blocks and earn block generation rewards. BNB Chain adopting DPoS has implemented a leveling mechanism to prevent the concentration of votes on a particular validator. However, voting token holders do not always act in economically rational ways. This causes disparity in rewards to votes by token holders. We investigated the BNB Chain and factors related to the reward rates. We calculated Spearman's rank correlation coefficient between reward rates and several factors: total delegate-related transactions, voting balance, voting balance change rate, and the average voting validators. As a result, we found that total delegate-related transactions have the strongest correlation with reward rates, followed by the voting balance change rate.
