About this app

BlockFact turns your smartphone into a trust machine. Every photo you capture is instantly registered on the StarkNet blockchain, creating an immutable, tamper-proof record of
authenticity that no one can dispute.

HOW IT WORKS
1. Snap a photo using the BlockFact camera
2. Your image is automatically watermarked, timestamped, and registered on-chain
3. A verified .facti file is created — your portable proof of authenticity

WHY BLOCKFACT?
In a world of deepfakes and AI-generated images, proving a photo is real matters. BlockFact gives journalists, creators, legal professionals, and everyday users a simple way to establish that a photo was taken by a real person, at a real place, at a real time.

KEY FEATURES
• Blockchain verification — Every photo is registered on StarkNet with a permanent, public transaction record
• .facti files — A universal proof-of-authenticity format containing your original image, metadata, and blockchain receipt
