On October 21, news reported that Vitalik responded to comments about the "Zuzalu, Apecoin Governance Forum, and Arbitrum DAO's level of guardianship" by stating: "Technically, any currency is permissioned: you need to obtain permission from an existing holder to become a holder. This indicates that there is actually an ongoing trade-off between the permission levels of Apecoin and ZuVillage, and we can envision a structure in between: becoming a member requires permission from multiple existing members, but it remains very open. For example, you can imagine a mechanism similar to secondary financing, weighted by existing member points to accumulate membership points. This is what I hope to see in the OP Citizen 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 achieve highly decentralized and permissionless formal membership, but not just token holding, that would be really cool."
