zk-face-recovery

Recover your Wallet using just your face and and trivia about yourself

Setup

1. Run npm install to setup circomlib

npm install && mkdir output

2. Compile circuit

circom circuits/poseidonHash.circom --r1cs --wasm --sym -o output/

3. Change to ptau-ceremony directory

cd output/ptau-ceremony/

4. To prove the circuit in one go, run:

bash ceremony.sh {circuit_name}

5. Alternatively you can perform step by step, the trusted setup is done in two parts

   1. The powers of tau, which is independent of the circuit
   2. The phase 2, which depends on the circuit

6. Start a new powers of tau ceremony

snarkjs powersoftau new bn128 12 pot12_0000.ptau -v

7. Contribute to the ceremony

snarkjs powersoftau contribute pot12_0000.ptau pot12_0001.ptau --name="First contribution" -v

8. Begin circuit dependent phase

snarkjs powersoftau prepare phase2 pot12_0001.ptau pot12_final.ptau -v

9. Generate proving and verification keys

snarkjs groth16 setup output/circuit.r1cs pot12_final.ptau circuit_0000.zkey

10. Contribute to phase 2

snarkjs zkey contribute circuit_0000.zkey circuit_0001.zkey --name="1st Contributor Name" -v

11. Export verification key

snarkjs zkey export verificationkey circuit_0001.zkey verification_key.json
