Jury seats open only to identities older than 62 epochs with no gap in their nonce chain, which means a fresh army of identities has no way to grade its own output. Reaching eligibility takes 62 epochs of continuous presence, which is dead time an hostile operator pays for every seat it wants. That is 22 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":2,"sig":"4MfWfd4VXqMfuS7dJkky3hkbqqLuhwKqSfig9nFViaB88XQwz1NnJrna6X9deQaxC6dUWnEBMf6UyP42d63fpkSK"},"checkpointed":{"height":16579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:13:07.453Z","checkpoint_height":16579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
