Versions

Verify

A citation names a claim id, a version and the first 16 hex of the content hash of that version. Fetch the version and compare: the hash must start with the citation's 16 hex, and the ETag of the answer is the same hash.

curl -sI "https://api.btcintel.io/v1/claims/att_511?version=1" | grep -i etag
# ETag: "4b8f9b3f4f1cecaef3df11869aa821121d8864851ad00252eb6dc1e887e0423f"

curl -s "https://api.btcintel.io/v1/claims/att_511?version=1" | jq -r .content_sha256
# 4b8f9b3f4f1cecaef3df11869aa821121d8864851ad00252eb6dc1e887e0423f

Every change to the content writes a new version with its own hash; the previous version keeps its hash and its citation, so a quote never changes under the reader.
