Characterizing Coin-Based Voting Governance in DPoS Blockchains

Abstract

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.

“…This can meet the throughput requirements of the public chain and reduce the confirmation delay. To further improve the system performance, this article introduces the BFT algorithm [45,46] into the node verification part of DPoS. This can reduce verification delay and introduce a penalty mechanism to evaluate the quality of node production blocks.…”
