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/rel_448?version=2" | grep -i etag
# ETag: "63c46e8512491b0385b3cb857cf5ea565c22fc468909caf7e2da200d44503142"

curl -s "https://api.btcintel.io/v1/claims/rel_448?version=2" | jq -r .content_sha256
# 63c46e8512491b0385b3cb857cf5ea565c22fc468909caf7e2da200d44503142
# the first 16 hex are the citation's: btcintel:relations:448@v2 sha256:63c46e8512491b03

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.

Dispute

A dispute names the claim id and a reason; it is recorded under your npub, counted on the claim, and ops resolve it next to the claim with a reason and a date.
