Zelyo mints credentials as sealed attestations on a scholarly ledger — then lets a holder prove a single fact in zero knowledge. The chain records only an anonymous seal. The rest stays private.

Three properties that make a credential worth sealing — each verifiable on-chain, without exposing the person behind it.
The ledger records only a nullifier and a bound address — no name, no grade, no course. The proof is the receipt; the data never leaves the holder.
A nullifier ties a single proof to a single identity. Reusing it across Sybil attempts is rejected — one seal, one claim, no duplicates.
Prove you satisfy a predicate — “track matches,” “grade in range,” “issued before date” — while every other attribute stays strictly private.
Credentials enter as leaves in a Merkle tree; the issuer publishes a single root. A holder distills one fact into a proof, sealed and recorded — and the original data is never transmitted.
Questions, integrations, or institutional inquiries — address your correspondence to the keeper of the ledger.
We answer inquiries about the protocol, issuance, and verification. Expect a considered reply — not an autoresponder.
