Four steps, no trust needed
- Download a day's Ledger and its .ots proof above.
- Go to opentimestamps.org, drop in the .ots file, then the ledger file.
- It shows the Bitcoin block that holds the timestamp. If one character of the ledger had changed, the check fails.
- To check a single agent file, work out its SHA-256 (Windows:
certutil -hashfile file.skill SHA256; Mac:shasum -a 256 file.skill) and find it in the list below.
Command line:
ots verify arguta-ledger-DAY.jsonl.ots with the free OpenTimestamps client.Every line in the ledger
