Proof That Lasts Forever
Tamper-proof evidence preservation with mathematical proof it hasn't been altered. Anchored to the blockchain. Verifiable by anyone.
How It Works
Three steps to tamper-proof evidence.
Upload Your Evidence
Drag and drop any file. Photos, documents, videos, audio.
Encrypted & Anchored
Your file is encrypted in your browser — we never see it. It's hashed and anchored permanently to the Arweave blockchain.
