How it works

Watch an artifact outlive the break.

A TRELYAN Vault Cell doesn't store your file — it seals its fingerprint on-chain, signed with a post-quantum signature that a quantum computer cannot forge. Hash anything below and see exactly what gets written.

① Take the fingerprint of any artifact

② This is the Vault Cell inscription
Artifact digest
SHA-512 computed live
Vault Cell
Signature
Falcon-1024 (FN-DSA) · det1024 encoding · 0xBA header · ~1236 bytes (variable, ≤1423 B) produced by the Foundation's offline post-quantum key — never shown, never on a server
On-chain check
Algorand falcon_verify opcode verified at consensus

That digest — and only that digest — is what a Vault Cell writes, once, forever. Change a single byte of your artifact and the fingerprint changes completely; the original inscription can never match the altered file. Proof without trust.

③ Why it survives the break

The threat. A large quantum computer will eventually break the elliptic-curve signatures that secure most of today's blockchains and identity systems. "Harvest now, decrypt later" means anything meant to last is already exposed.

The answer. TRELYAN signs with Falcon-1024, a lattice-based scheme NIST selected in 2022 for standardization (designated FN-DSA; FIPS 206 is still in development). Lattice signatures are believed secure against quantum attack.

And the verification isn't a promise on a website — it runs inside the Algorand protocol itself. The falcon_verify opcode checks every signature against its public key during transaction execution. If it doesn't verify, the inscription is rejected by consensus. No one — not even the Foundation — can write an inscription that doesn't hold.

④ See it live on-chain

The verification engine is already running on Algorand. The TRELYAN application below has had real artifacts inscribed and verified by falcon_verify — you can inspect it on any block explorer.

An honest note. This page is a teaching tool. The digest above is computed live and is real; the signature and Vault Cell fields are shown for structure (the authoritative specification is the TRELYAN white paper). TRELYAN is pre-launch — the verification protocol is live on TestNet and the codebase is under independent review before any public mint. We show you the mechanism so you never have to take our word for it.
