Timestamp your work with dual independent sources. Files never leave your device. Verify forever.
A hash proves nothing about when. Here's what makes FairStamp different.
Every receipt includes timestamps from two independent sources: our server (Google NTP traced) and Cloudflare's atomic-synced edge network. Both are cryptographically bound together. To falsify a timestamp, you'd need to compromise two global infrastructure providers simultaneously.
Every receipt links to our open-source verification tools. Receipts generated today will verify correctly in 2035 and beyond — even if FairStamp ceases to exist.
Each timestamp generates a cryptographically signed certificate suitable for legal proceedings, IP disputes, and prior art claims.
WASM-powered hashing runs entirely in your browser. Your files never touch our servers.
Drag entire directories. Photos, videos, code, documents — any file type.
SHA-256 computed via WASM in your browser. Files never leave your device.

FairStamp is the timestamp layer of Wave3 Digital Trust, a trust infrastructure company building cryptographic tools for creators and enterprises.
Founded by Dr. Darrell L. Young, P.E. — former Principal Technical Fellow at Raytheon (38 years) and Research Professor at SMU Cybersecurity — Wave3 develops zero-knowledge proof systems that enable verification without disclosure.
Cryptographic proof that your work existed at a specific moment in time.
