Photos With
Receipts
Every photo captured in Notchd is hashed, timestamped, and anchored to the blockchain. This ensures no one can question its authenticity.
Recorded on chain
Core Infrastructure
Built on Cryptographic Certainty.
SHA-256 Hashing
Every pixel is processed through a bank-grade cryptographic algorithm, generating a unique digital fingerprint that identifies any tampering.
Blockchain Anchoring
Metadata and hashes are permanently anchored to the ledger, creating a globally accessible, immutable proof of existence.
Native Capture Only
To maintain institutional integrity, Notchd only verifies photos captured within the app's secure sandbox environment.
Why It Matters
Photos people can check.
When you post a photo, people should be able to tell if it's the one you actually took. Notchd gives you a record you can share with friends, followers, or anyone who asks.
Take your photo
Open Notchd and capture it there. You'll get a record tied to that image.
Share its record
Send the link with your photo so others can check whether it matches what you captured.
Try it with your next photo.
Download Notchd, take a photo in the app, and share its record with anyone who wants to check it.
