ETHDenver 2021 Opening Ceremonies: Vitalik Buterin, Ethereum Foundation
summary
Argues that membership needs concrete primitives and compares three concrete systems: coin holdings (used in nonbinding coin votes like the 2016 DAO fork and the 5→3 issuance vote, vulnerable to wealth concentration and vote buying), one per person (Gitcoin Grants, BrightID; easy and egalitarian but fraud-prone), and duocracy (trusted multisigs of 5/7/13 or client teams; filters for deep contributors but scales poorly). Proposes alternatives: proof of medium participation (conference attendance, POAP), exams, quadratic coin membership to cut a 300,000-weight vote toward ~500, and indirect proof-of-contribution (OpenCerts, Opolis experiments).
