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 BNB Chain and found that token holders who frequently generated delegate-related transactions earned more rewards than those who did not. In addition, we found a greater disparity in reward rates between token holders who have voted and maximized their rewards, compared to those who did not.
