Everlasting's audit log is a SHA-256 hash chain. At regular intervals we submit the chain's head hash to independent public transparency services — starting with OpenTimestamps Bitcoin calendars. Once confirmed on Bitcoin, the head hash inherits the Bitcoin blockchain's proof-of-time. That means anyone — a probate court, an attorney, a family — can verify that a given head existed at or before a given moment without trusting our database or our servers.
pip install opentimestamps-client or see opentimestamps-client on GitHub..ots receipt for any anchor row below, and save the 64-character head SHA-256 to a file named head.txt (hex, no newline).ots verify audit-anchor-…ots -d head.txt. The tool reads the Bitcoin block header inclusion proof directly from a public Bitcoin node and prints the block's UTC timestamp. That timestamp is your independent proof-of-time.Freshly submitted anchors are marked submitted — Bitcoin confirmation typically upgrades them within an hour. You can re-run ots upgrade on the same receipt at any time to fetch the completed Bitcoin proof.
