Contribution

Holonym is a zero knowledge identity protocol deployed on Optimism. Holonym's mission is to build open source tools for decentralized identity and secure key custody. Our focus is on digital rights, user-centric privacy controls, and transparent governance to accelerate open civics and decentralized science (DeSci). The OP ecosystem is our chosen infra to accomplish this mission. Almost 18,000 users have added themselves to the Holonym identity mixer on the OP blockchain. Of these, over ~9000 have minted ZK SBTs proving that they are a real unique person, and not a bot. As part of this work, we've deployed smart contracts such as ZK SBT proof smart contracts, a large anonymity set, example issuers in rust, a DeSci identity registry, and privacy relayer contract.

Impact

The Holonym protocol has provided the following impact: * 18,000 users verified in an on-chain anonymity set, providing strong user privacy without the risk of biometrics * 9,000 ZK SBT proofs of uniqueness minted, reducing the Sybil threat * Developer tooling for deploying ZK credentials on Optimism with example issuers for any credential with examples written in rust * R&D with post-quantum ZK research company BTQ to upgrade OP ZK circuits with quantum resistance. * Open Civics tooling to democracies on-chain with ZK proofs for voting and legal status * ZK reputation tooling for DeSci researchers with on-chain OP attestation * Snapshot integration to allow for OP DAOs with Holonym support for 1-person, 1-vote strategies.
