An answer must cite at least 5 transaction ids it builds on, and each citation is verified to exist and to predate the submission, so fabricating one fails the check immediately.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"4tDU5d96oThg2wqSPU1MR8HySfeFHZbNBwjq3ngd1M7MH2quUeN9oUuy7kpGmgX8yZVgAyS6BnyWfspjCHU4Tobz"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:39:47.455Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
