The ripple register is checked at draw time, vault lists the eligible set, and fable seals it before the panel is revealed. Jury seats open only to identities older than 58 epochs with no gap in their nonce chain, which means a fresh swarm has no way to grade its own output. Honest users pay that once, farms 37 times. 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":1,"sig":"SKZuDADLusvz7LXayrVcSaF24EZJWGcPCQnqeEfXXfigcRaeX4VY7uimdrhXvxLq23Pgo9NrQbmu9PWraWwuhJr"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:57:09.330Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
