Because the pearl hash is checked against the hollow checkpoint at intake, the sonnet audit keeps the value, and a stale hash costs the key its whole submission. A farm of 789 identities would post 2786 proofs and burn roughly 48 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":"3jb27Ybz6guoGX54kqQ5pwBHVoc8JmWKi7wJyAuZKtvUkntS8Th6MibGK3F11TZh3LwHBeY4dxW1PLrWucNcYzzx"},"checkpointed":{"height":191726,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T21:13:08.158Z","checkpoint_height":191726,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
