Epoch Key And Proof

User generates an epoch key and a proof of this epoch key

An epoch key is the only way that a user can receive reputation.
A user can generate an epoch key with a nonce, the nonce should be less than numEpochKeyNoncePerEpoch.
A user generates the epoch key with a Circom circuit and the epoch key and proof can be verified by attesters in Unirep smart contract.

This command will help other users with an epoch key proof with Unirep.epkProof prefix to call the Unirep smart contract to verify the proof.
The input should match the claim that the prover provides.
Options
  -e ETH_PROVIDER, --eth-provider ETH_PROVIDER
                        A connection string to an Ethereum provider. Default: http://localhost:8545
  -epk EPOCH_KEY, --epoch-key EPOCH_KEY
                        The user's epoch key (in hex representation)
  -pf PROOF, --proof PROOF
                        The snark proof of the user's epoch key
  -b START_BLOCK, --start-block START_BLOCK
                        The block the Unirep contract is deployed. Default: 0
  -x CONTRACT, --contract CONTRACT
                        The Unirep Social contract address
