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_140?version=1" | grep -i etag
# ETag: "43d5ed4285cf45095b5267fb5878293a68d88ef1342446d4639b9dd6458de97d"

curl -s "https://api.btcintel.io/v1/claims/att_140?version=1" | jq -r .content_sha256
# 43d5ed4285cf45095b5267fb5878293a68d88ef1342446d4639b9dd6458de97d
# the first 16 hex are the citation's: btcintel:attributions:140@v1 sha256:43d5ed4285cf4509

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.
