Most people hear "blockchain" and think crypto. For artists, it's something more useful: a permanent, public record of exactly when your work existed — one that nobody can alter or delete, not even Vulta.
What is Blockchain Anchoring?
When you anchor your work, Vulta takes a cryptographic fingerprint of your file — called a SHA-256 hash — and writes it to the Polygon blockchain with a timestamp. That's it. No one stores the actual image on-chain; just a mathematical proof that this exact file existed at this exact moment.
Think of it like a notary stamp you can verify yourself, from anywhere, forever. The record lives across thousands of independent computers, so there's no way to alter or delete it after the fact.
Why SHA-256?
SHA-256 is the same algorithm that secures the Bitcoin network. It produces a unique "fingerprint" for any file — change even a single pixel and the hash changes completely. This means the hash on the blockchain will only match your exact original file, making it impossible for anyone to claim they owned a different version.
Why Polygon?
Vulta uses the Polygon blockchain rather than Ethereum because it offers the same security and immutability at a fraction of the cost. Ethereum transactions can cost $20–$100 in gas fees; Polygon transactions typically cost less than a cent. This makes it practical to anchor every piece of work — not just your most commercially valuable.
How Does This Actually Protect Me?
You own copyright the moment you create something — you don't need to register it. The problem is proving you created it first when someone disputes it. A blockchain anchor gives you a timestamped record that predates any copy, doesn't rely on your word alone, and lives on a public ledger that's independent of Vulta entirely. You can link directly to it in a DMCA notice and anyone — a platform, a lawyer, a judge — can verify it themselves.
Anchor your work on the blockchain today.
Vulta writes a permanent, public timestamp of your file to the Polygon blockchain — for less than a cent per piece.

The blockchain answers "when did you create it?" — but it doesn't prove that a specific stolen copy came from your original file. That's what the forensic watermark is for. Together, they cover both questions. Here's how the two work together.
