Universal Proof Protocol
One artefact format for any claim, any subject, any counterparty. Signed, hashed and portable — verifiable by anyone, with no call back to us.

Post-quantum by default
Autonomous trust infrastructure for a post-quantum world where most actions are taken by AI. Issue cryptographic identities, mint signed proofs, verify them anywhere, and keep a hash-chained evidence trail that answers “prove it” in seconds.
No per-verification fees. Create an account in under a minute.
The whole platform rests on these. Everything else composes on top.
One artefact format for any claim, any subject, any counterparty. Signed, hashed and portable — verifiable by anyone, with no call back to us.
Identities use ML-KEM-1024 key encapsulation with rotating material, so traffic archived today cannot be unwound by a quantum-capable adversary tomorrow.
Model-agnostic identity, mandates and scoring for autonomous actors — every agent action authorised against policy and written to a hash-chained evidence trail.
