User Sign Up

User and attester sign up

• There are two different actors in Unirep: user and attester

• A user with a semaphore identity can generate an epoch key without revealing the semaphore identity and identity commitment

• An attester is associated with his Ethereum account or a smart contract. When an attester sign up, the attester has a unique attester id, and whenever the attester submit attestations, other users will know the attestation comes from which attester id.
