ZERO_KNOWLEDGE // JWT_VERIFICATION // STARKNET
PROVE IDENTITY.
REVEAL NOTHING.
Cerebro generates Groth16 zero-knowledge proofs for JWT verification. Authenticate users on Starknet without exposing sensitive token data on-chain.

HOW IT WORKS
01
SUBMIT
Send a JWT and its RSA modulus to the Cerebro prover API.
02
PROVE
The circuit extracts claims and generates a Groth16 proof via rapidsnark.
03
VERIFY
Submit the proof on-chain. The Cairo verifier confirms validity in a single transaction.

GASLESS_ONBOARDING
Onboard users to Web3 with familiar Web2 authentication flows. No crypto holdings needed to start.
PRIVACY_PRESERVING
Verify off-chain credentials on-chain without exposing payload data in transaction calldata.
SESSION_KEYS
Authorize session constraints on-chain using JWT-backed ZK proofs for time-limited delegated access.
