Holonym is a privacy-preserving identity protocol. It uses zero knowledge proofs to allow users to prove they are a unique human and receive a high score Gitcoin Passport stamp for Sybil Defense without revealing their identity.
Holonym provides Sybil Defense for Gitcoin Grant Rounds through an integration with Gitcoin Passport. Holonym lets users perform zero knowledge off-chain KYC to privately mint an SBT-NFT "proof of unique person" attestation to an Optimism EOA.
This grant is intended to accomplishing the following with OP incentives:
Prove they are a unique human with a Holonym Gitcoin Stamp on Optimism
Maximize their proof strength by minting multiple proofs on their identity
Support Public Goods by donating in Gitcoin rounds
The Holonym stamp in the Gitcoin Passport is the strongest single form of Sybil defense that a user can verify with. So far, over 10,000 users have ZK-KYC'd in the past two weeks, adding themselves the anonymity set stored on Optimism. This is only a small portion of the total Gitcoin Passport user base.
We would like to offer incentives to encourage more users to verify and contribute to public goods. We would like to do this with a retroactive distribution of rewards to users that have minted SBTs and donated to Gitcoin grants.
