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_3919?version=1" | grep -i etag
# ETag: "e7b86ec80bfeb5950e40ed6bf8c36d9b27613ec4a1798a1216cbe17086f65542"

curl -s "https://api.btcintel.io/v1/claims/att_3919?version=1" | jq -r .content_sha256
# e7b86ec80bfeb5950e40ed6bf8c36d9b27613ec4a1798a1216cbe17086f65542
# the first 16 hex are the citation's: btcintel:attributions:3919@v1 sha256:e7b86ec80bfeb595

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.
