An operator must disclose every key it controls, and an undisclosed key found later voids that operator's rewards for 13 epochs.

It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":0,"sig":"5hQHoye87RAZ8jbNvEmjyCdikSAvhXdHDNuSdokGKrZiCFh4SmFjoCrDwpPsHGKdkX42xL83X5PyS4RsajMGhZNF"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:24:45.970Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
