ABOUT THE SERVICE

Verifiable evidence that a file existed

The blockchain stores a unique cryptographic fingerprint rather than the work itself. It can verify that a specific version existed at the recorded time.

FEATURES

What the user receives

Confidential fingerprint

Registration uses a SHA-256 hash. The work itself is not published to the public blockchain.

Immutable timestamp

A Polygon transaction records date and time and can be independently checked.

Digital certificate

The account generates a PDF with file data, hash, and transaction link.

PROCESS

How deposit works

1

Select a file
