ProofSnap

Web pages as signed evidence

ProofSnap captures a public web page as an evidence package: screenshot, HTML, page text, network metadata, SHA-256 hashes, a signed manifest, chain of custody, an OpenTimestamps Bitcoin proof and, on request, an eIDAS qualified timestamp. In your AI you can capture a page, compare it with an earlier capture and see what changed, watch a page on a schedule, organize captures into matters, verify your stored captures and check a manifest hash in ProofSnap's public ledger.
