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_2641?version=1" | grep -i etag
# ETag: "5dd0650b409fc737eb315a77c42fc543551bef77b100ef7de7dcd0730ad4b5f2"

curl -s "https://api.btcintel.io/v1/claims/att_2641?version=1" | jq -r .content_sha256
# 5dd0650b409fc737eb315a77c42fc543551bef77b100ef7de7dcd0730ad4b5f2
# the first 16 hex are the citation's: btcintel:attributions:2641@v1 sha256:5dd0650b409fc737

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.
