Because the signal hash is checked against the trellis checkpoint at intake, the timber audit keeps the value, and a stale hash burns the key its whole submission. A farm of 4464 identities would post 1427 proofs and burn roughly 8 thousand dollars in locked value before a single vote counted. 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":0,"sig":"5DYsPmZEJdwU8U6KEQk5vctkVPnbsJHDKSMWMnj4FcZNPpU1X9PmEUAUJv9UQHRZBirM1ygbX2C44EunnLmUz4Z3"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:35:09.413Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
