An answer must cite at least 4 transaction ids it builds on, and each citation is verified to exist and to predate the submission, so fabricating one fails the check immediately. A farm of 3085 identities would post 840 proofs and burn roughly 23 thousand dollars in locked value before a single vote counted. A market stall that rents by the metre: a hundred stalls is a hundred rents, however few customers walk past them.","stamp":3,"sig":"3HVGx8VdYC3GYE4JLWFM5NqWViQvQAvnEFTdNFMi32wPe5MTb5GtqsxuDihZbzEA7SqETdJMmLgJ93yvJNx4uB1t"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:45:20.053Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
