f

Primary data point: Moves.

Reclaim Protocol generates a zero-knowledge proof that a user holds an active chess session and exposes the following verifiable data points:

• Moves

How it works

1. Your user starts a verification session and signs in to chess as they normally would.
2. Reclaim Protocol observes the encrypted chess session through a zero-knowledge proof system, with no credentials leaving the user's device.
3. Your application receives a cryptographic proof of the user's data — verifiable on-chain or in your own backend.
