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_498?version=1" | grep -i etag
# ETag: "7fe8eaf4f56405ae983598c00556b48220a3f6cff676bf76946d687dfa004735"

curl -s "https://api.btcintel.io/v1/claims/att_498?version=1" | jq -r .content_sha256
# 7fe8eaf4f56405ae983598c00556b48220a3f6cff676bf76946d687dfa004735
# the first 16 hex are the citation's: btcintel:attributions:498@v1 sha256:7fe8eaf4f56405ae

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.
