On October 21st, Vitalik replied to a comment about the "governance levels of Zuzalu, Apecoin Governance Forum, and Arbitrum DAO," stating: "Technically, any currency is permissioned: you need permission from an existing holder to become a holder. This indicates that there is actually a continuous trade-off space between the permission levels of Apecoin and ZuVillage, and we can imagine the structure in between: becoming a member requires permission from multiple existing members, but it is still very open. For example, you can imagine a mechanism like a second-round financing style, weighted by existing member points, to accumulate member points. This is what I hope to see in OP Citizen's Home, Zuzalu community, and other DAOs that are experimenting. Formalizing and measuring membership is upstream of any formal governance, and if there are more ways to obtain highly decentralized and permissionless formal membership, but not just token holding, that would be really cool."
