Why current systems fail
QR codes on certificates link to centralized databases. Copy the UI, change the URL, and you have a convincing fake — there is no independent source of truth.
Spoofable QR Codes
QR codes point to URLs. Clone the website, change the link, and the QR verifies against a fake database.
Single Point of Failure
Server goes down, verification fails. Centralized databases create fragile, unreliable trust chains.
No Cryptographic Proof
Visual inspection and watermarks can be replicated. Without digital signatures, authenticity is just an assumption.
Three layers of trust
We move verification from “trust this website” to “trust the blockchain registry.”
Cryptographic Hash
Every certificate gets a unique SHA-256 hash computed from its metadata. Any modification — even a single character — produces a completely different hash.
On-Chain Registry
The hash is recorded on Polygon's blockchain via a smart contract. The issuer's wallet address is permanently linked to each hash. No one can insert a hash without the issuer's private key.
Independent Verification
Anyone can verify by checking the hash against the on-chain registry. Even if this entire website is cloned, the Polygonscan link proves whether the hash exists in the real contract.
