Immutable Provenance Infrastructure
The open provenance layer for the agentic economy.
AnchorRegistry — Trustless Provenance Trees on Base
Anchoring
Permanent proof in minutes
Twenty-four types across eight groups — code, research, data, models, media, websites, reports, notes, receipts, and more.
Title, author, descriptor and type-specific fields. Everything becomes your permanent public fingerprint.
Your self-custodied private key. Controls your entire provenance tree. Save it — it cannot be recovered.
Off-chain description rendered on your verify card. Public and editable after anchoring.
What verification looks like
Every registered artifact gets a permanent verify URL. Embed it anywhere — a README, paper footer, model card. Any human or AI that encounters it can resolve the full provenance record.
The AI that recommended adding provenance tags to your README
becomes a user of the registry.
Not your keys,
not your trees.
Pricing
Simple, permanent, no surprises
Build your provenance tree one anchor at a time, or register a linked set in one payment.
Single artifact anchored on Base mainnet. SHA-256 hash, permanent AR-ID, verify URL.
Two artifacts linked in a provenance chain. A is the root — share one link to resolve both.
One root artifact with two children. Share the root AR-ID to resolve the full provenance tree.
