Constitutional Voter Committees (CVCs) are groups of verified governance token holders that organize around a common set of goals. CVCs have official recognition from the DAO and are not too dissimilar from a political party. Members collaborate on governance matters and try to influence the direction of the DAO towards their specific interests. The concept originated in the Maker ecosystem, with the most recent CVC being the Growth CVC - a group that prioritizes expansion, experimentation, and growth.
PlutusDAO - A GovFi protocol. PlutusDAO is a protocol that aggregates governance power in selected protocols on Arbitrum. The DAO believes that governance control can be monetized in the future, e.g. via directing treasury deployment, emission schedules, and strategic direction. Governance token holders are incentivized to convert (read: one-way, irreversible lock up) their governance tokens into the yield bearing pls- version (e.g. ARB → plsARB). Holders can then stake pls- tokens to receive both $PLS rewards and the normal staking emissions from the underlying token. Governance tokens will be locked in Plutus forever, and holders can only exit their positions via discounted liquidity pools. As of now Plutus has amassed significant governance power in $DPX (52%), $JONES (90%), $SPA (45%), and a minor stake in $ARB (0.65%).
Proto-DAOs are aspiring DAOs that have taken first steps to progress from being a simple online community towards a more decentralized organization. They might have implemented a first set of building blocks that enable decentralization, but fall short of the fully decentralized, onchain nature of more mature DAOs.
