There are two types of reputation proof in Unirep:
Reputation proof: how much reputation that a user has, which includes reputation from all attesters and airdropped karma.
Reputation from attester proof: how much reputation from a specified attester, which is indicated by attester id
Both of the reputation proofs are generated by user with a semaphore identity and the proof can be verified by everyone at the Unirep smart contract.
This proof will be generated with a post, a comment, an upvote and a downvote action. The proof is used to ensure that a user has enough reputation to make the action.
There is another option that a user can choose to prove how much reputation he has and it exceeds the required reputation for the action.
See
After user made an action, it will create a proof with Unirep.reputationProofprefix. Other users can verify this proof at the Unirep smart contract.
verifyReputationProofThis command will help other users with a proof with Unirep.reputationProofprefix to call the Unirep smart contract to verify the proof.
The input should match the claim that the prover provides.
Actions includes: publishPost, leaveComment, and vote
genReputationProofFromAttesterThe prover (the user with a semaphore identity) can choose to prove how much reputation he receives from a certain attester id, including:
minimum positive reputation received from the attester since the first epoch
maximum negative reputation received from the attester since the first epoch
minimum difference between positive and negative reputation from the attester since the first epoch
what is the graffiti pre-image of the reputation, where the graffiti is optional to be attached from the attester
If the reputation matches the user's claim, the Circom circuit will generate a valid proof.
A string with Unirep.reputationProofFromAttester prefix is the proof of the reputation claim.
verifyReputationProofFromAttesterThis command will help other users with a proof with Unirep.reputationProofFromAttesterprefix to call the Unirep smart contract to verify the proof.
The input should match the claim that the prover provides.
