# upgrade_ots.sh — Walk every .ots in /evidence and run `ots upgrade` to pull
|
|
# the latest Bitcoin attestation into the file. Safe to run on a cron.
|
|
#
|
|
# Usage: ./upgrade_ots.sh /path/to/evidence/root
|
|
#
|
|
# A fresh `ots stamp` produces an incomplete proof referencing a calendar
|
|
# server. After the next Bitcoin block confirms (~10 min) and a few more
|
|
# confirmations land, `ots upgrade` rewrites the .ots file in-place to include
|
|
# the full Bitcoin-attested proof. Once upgraded, the .ots file is permanently
|
|
# verifiable even if every calendar server disappears.
