“…In blockchains, it is necessary to rely on consensus protocols to provide data consistency among nodes in a peerto-peer network. As the most well-known consensus protocol, the Proof-of-Work (PoW) consensus protocol has secured Bitcoin (Nakamoto 2008) and Ethereum (Wood 2014) for almost a decade. However, PoW requires decentralized consensus to be fulfilled in a large-scale peer-to-peer network (Lin et al 2021).…”

Delegated-Proof-of-Stake (DPoS) blockchains are governed by a committee of dozens of members elected via coin-based voting mechanisms. This paper presents a large-scale empirical study of two critical characteristics, personal impact and participation rate, of three leading DPoS blockchains. Our findings reveal the existence of decisive voters whose votes can alter election outcomes, as well as the fact that almost half of the coins have never been used in committee elections. Our research contributes to demystifying the actual use of coin-based voting governance and offers novel insights into the potential security risks of DPoS blockchains.
