Aurora Pathways · Aurora Proof

Seal anything. Verify forever.

A public, tamper-evident registry for anything that matters — contracts, releases, designs, certificates, evidence. Your artifact is fingerprinted in your browser and never leaves your device; only the fingerprint is sealed into a hash chain where every entry locks the one before it. Alter history, and every later seal breaks in public.

Chain: connecting… Proofs sealed: … Pattern in production: 10 chains across the Aurora estate

Seal something now

Free tier: three seals an hour. The file itself is hashed locally — we never see it, store it, or want it.

Sealed. Keep your proof ID with the original artifact — together they prove it existed, exactly in this form, no later than now.

Verify a proof

By proof ID — or re-hash the artifact and check the fingerprint itself.

How it holds

01 · FINGERPRINTHash locallyYour browser computes the artifact's sha256. Change one byte of the artifact and the fingerprint changes completely.
02 · SEALChain itThe fingerprint is sealed into a chain where every entry hashes the one before it. Nothing can be edited or removed without breaking every later seal.
03 · VERIFYForeverAnyone with the ID — or the artifact — can verify against the public chain. No account. No trust in us required.

What people seal

AgreementsSign on paper, seal the scan — the terms can never be quietly rewritten.
Creative workDesigns, music, manuscripts — prove you had it first.
CertificatesDiplomas, credentials, awards — issue them verifiable from birth.
Releases & buildsSoftware artifacts and reports, fingerprinted at ship time.
CompliancePolicies and disclosures, provably unaltered since filing.
EvidencePhotos and documents, timestamped before disputes begin.

The API

Plain HTTP. The free lane is throttled; the commercial lane pays a cent of USDC per seal over x402 — no accounts, no keys, the payment is the authentication.
# seal a fingerprint (sha256 of your artifact)
curl -X POST https://aurorapathways.xyz/api/proof \
  -H "Content-Type: application/json" \
  -d '{"hash":"<64-char sha256 hex>","label":"release v1.4.2"}'

# verify by proof ID

Honesty, in writing

A seal proves one thing, precisely: this exact fingerprint existed no later than the sealed moment. It does not prove who authored the artifact, that its contents are true, or that it is unique elsewhere. That precision is the product — courts, partners, and buyers can rely on exactly what it claims and nothing more. This is the same discipline that runs ten production chains across Aurora's client platforms, including Aurora Shield's daily attestations.

Aurora Proof is a product of Aurora Pathways. Free tier for people; the x402 lane for machines; sealed engagements for enterprises via Aurora Shield.
