How to Hash & Notarize

1

Select Your Asset

Choose the correct asset category from the sidebar (Documents, Pictures, Audio, or Videos) to organize your blockchain proofs.

Local Cryptographic Hashing

Drag and drop your file. Your browser uses the Web Crypto API to generate a highly secure SHA-256 hash locally. Your actual file never leaves your device.

3

Cheese Blockchain Stamp

Only the unique 64-character hash footprint is transmitted to the Cheese Blockchain via a smart contract, securing your timestamped proof.

Immutable Verification

You receive a Transaction ID. Anyone can verify the asset's authenticity in the future by recalculating its hash and searching it in the top bar.
