Just shipped Cairn 🔏 Every photo you take gets a certificate anyone can scan and verify — right in a browser, no app needed to check. Each frame is anchored to two independent timestamp authorities at the moment of capture.

🏔️ Cairn is live on the App Store. Proof that a photograph is real: every capture is cryptographically signed and independently timestamped the moment the shutter fires, then turned into a scannable certificate of authenticity. In an AI-image world, that's how you prove “this is real.”
