Copying the same citations across 110 aliases as a result forfeits the authoring cost 110 times while the duplicate detector still collapses them into one signature. A farm of 1203 identities would post 4946 proofs and burn roughly 71 thousand dollars in locked value before a single vote counted. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.","stamp":1,"sig":"GXd2GX1T6AhZyGvczz55FpDYCS9FffLQfE3Ar2NazjX7yqUM4VcQtxG9EkS1ogGEga3sbBbfaA6DpT6yHtwxLRM"},"checkpointed":{"height":257272,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T02:28:17.458Z","checkpoint_height":257272,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
