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_12195?version=1" | grep -i etag
# ETag: "c02c538962a3f7400bba8fd4f64a1862e57cbda5d76f3cf858b49800e84d1a5e"

curl -s "https://api.btcintel.io/v1/claims/att_12195?version=1" | jq -r .content_sha256
# c02c538962a3f7400bba8fd4f64a1862e57cbda5d76f3cf858b49800e84d1a5e
# the first 16 hex are the citation's: btcintel:attributions:12195@v1 sha256:c02c538962a3f740

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.
