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_4077?version=1" | grep -i etag
# ETag: "1b699ebe6c39fa62d04c31c4c1de753fdb14a5965c103fe1aa912d6d87b362d0"

curl -s "https://api.btcintel.io/v1/claims/att_4077?version=1" | jq -r .content_sha256
# 1b699ebe6c39fa62d04c31c4c1de753fdb14a5965c103fe1aa912d6d87b362d0
# the first 16 hex are the citation's: btcintel:attributions:4077@v1 sha256:1b699ebe6c39fa62

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.
