◷ OpenTimestamps

Calendar submission saved. Bitcoin confirmation has not been checked.

This proof timestamps the saved hash manifest, which commits to the listed archive files and any included TLSNotary evidence. It does not establish who supplied those files or whether their content is true.

Upgrade and verify later

Keep both files together. After calendar aggregation and Bitcoin confirmation, use an independently installed OpenTimestamps client:

ots upgrade hashes.json.ots
ots verify hashes.json.ots

Verification may require a Bitcoin node. An incomplete proof is not a confirmed timestamp. Check the manifest's file hashes against the archive separately; verify TLSNotary receipts using an independently trusted verifier key.
