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_3400?version=1" | grep -i etag
# ETag: "5c12a1b8e3aa38bbdc45131b60a8702ec5661f63b18f07e26bcc1fc6ef271506"

curl -s "https://api.btcintel.io/v1/claims/att_3400?version=1" | jq -r .content_sha256
# 5c12a1b8e3aa38bbdc45131b60a8702ec5661f63b18f07e26bcc1fc6ef271506
# the first 16 hex are the citation's: btcintel:attributions:3400@v1 sha256:5c12a1b8e3aa38bb

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.
