Fingerprint sealed
At upload, each file is hashed with SHA-256 and sealed into an append-only ledger. The fingerprint is immutable.
Thyna gives every published file a signed, public receipt: its fingerprint, the contributor consent, the compliance clearances it passed, a timestamped timeline and payment confirmation.
Four deterministic steps, from the moment a contributor uploads to the moment a lab verifies the signature on its own.

Privacy gate, AI-generation check, duplicate and web-scrape detection, quality control, human review. Each result is recorded with its evidence.
A public receipt is signed with Glint's Ed25519 key: fingerprint, consent, clearances, timeline and payment confirmation.
A lab exports the receipt, takes our public key, and verifies the signature independently. No trust required, no login.
Provenance is anchored in a signed, append-only ledger in Postgres, inside an EU entity. The same independent verifiability as an on-chain proof, with none of the procurement friction. You verify a signature against our public key, and that is all.
Each receipt lists the full clearance taxonomy. The checks we run on every file are verified, with their evidence. The heavier stack is activated on an enterprise pilot and shown as such, never claimed before it runs. Each line is an automated check recorded per file, honest about what has run and what has not.
Type a hash, read the signed receipt, check the signature against our public key. No account, no call, no trust required.
