Interlink

Interlink is an identity network built around proof of personhood, placing liveness checks, reputation and federated learning on one chain for applications that must separate people from automated accounts. It targets the capture of incentive distribution and governance voting by bulk accounts: device fingerprints and phone numbers can be registered at scale, and verification results do not carry across applications.Verification results exist as credentials, so an application can read the credential to learn whether an address belongs to a person.

Users register once through face liveness detection to mint an Interlink ID, and the process retains no original images. Model training uses federated learning, with gradients computed locally and only aggregated afterwards, so raw data stays on device. Developers call verification results and reputation scores through an SDK, while the chain records only credentials and authorisations.
