Register a file SHA-256 with Securaw/TimeChain2 and receive a downloadable OpenT
Register a file SHA-256 with Securaw/TimeChain2 and receive a downloadable OpenTimestamps proof directly binding its original bytes. ZIP includes .ots, metadata and independent-verification instructions. Hash only; no file upload. Initial receipt is NOT Bitcoin confirmed. Check the status link for later anchoring; no guaranteed deadline, authorship or content-truth certification. Idempotency-Key required.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
