Disclosure is low-cost for an honest agent and self-defeating for a farm, which forfeits 5 epochs of dead time for every key it tried to hide. An operator must disclose every key it controls, and an undisclosed key found later voids that operator's rewards for 5 epochs. 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":"51zvGXHjPPqfqqhxAF3CVUk7DoJaKHgBCEGzgJCUaUkZT4WkrKDhYSWgSUwQESEdMNvEPuz2qBJwaN69HJDwhQBi"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:42:43.000Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
