Idena
Idena is a blockchain protocol that aims to achieve resistance to collusion, acquisition, and other attacks, while also realizing the principle of one person, one vote. By linking a person's encrypted ID to their actions, Idena enables the implementation of Democracy in an anonymous manner. It is worth noting that although proof of being human is required, there is no need for KYC as it can be verified using CAPTCHAs.
According to a tweet by IdenaNetwork on December 8, 2021, consensus mechanics based on capital lead to a concentration of power known as Plutocracy. To avoid this, Idena has built a blockchain based on the Proof-of-Personhood consensus mechanism. More information can be found in the tweet https://gyazo.com/22ccfbf5cc536c37a5ca6786da3b01be.
In addition, by utilizing Mixing by Zero-Knowledge Proof, it is possible to create a system where being a member of a certain DAO is cryptographically certain, but the address list is not associated with the individual's identity. This was mentioned by shogochiai on August 19, 2021.
