A decentralized timestamp notary on Ethereum.

Prove you had a file on a specific date — no uploads, no middlemen, no trust required. Your file never touches a server: a SHA-256 hash is computed in the browser via the Web Crypto API, then anchored on Ethereum. Once on-chain, the fingerprint can't be altered or backdated.

So far:

• 10.32 GB of data notarized
• 1,847 files timestamped
• 24,519 on-chain block anchors
• ~1.2s average hash computation
• 99.97% uptime since launch

Built it because trusting a centralized notary to stamp a PDF never sat right with me.
