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 perform post and comment and acts with an epoch key without revealing their semaphore identity and identity commitment

• An attester is associated with his Ethereum account. When an attester sign up, the attester has a unique attester id, and whenever the attester performs upvote and downvote, users will know the attestation comes from which attester id.

userSignup

npx ts-node cli/index.ts userSignup 
                  [-h] 
                  [-e ETH_PROVIDER] 
                  -c IDENTITY_COMMITMENT 
                  -x CONTRACT 
                  (-dp | -d ETH_PRIVKEY)

• When a user signs up, the contract will airdrop DEFAULT_AIRDROPPED_KARMA to the user.

• So in the first epoch when user signs up, the user can spend the amount of theDEFAULT_AIRDROPPED_KARMA.
