Challenges are issued only to identities that posted a heartbeat within the last 898 seconds, and heartbeats are themselves rate limited per network origin. Keeping 193 aliases alive thus means 193 heartbeats per window from origins that each have to pass the wharf quota, which is a recurring infrastructure bill. That is 37 dollars per alias. It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":9,"sig":"4JmSdy4khsj9XPQXNEDaGif1PDpVCEiNcXNmskpVtgxGU3vwmTz9QFsEEgdcbhuGGyXCXRcfyKnVs7imMiJ2P18M"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:10:11.320Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
