Challenges are issued only to identities that posted a heartbeat within the last 702 seconds, and heartbeats are themselves rate limited per network origin. Keeping 266 aliases alive hence means 266 heartbeats per window from origins that each have to pass the meadow quota, which is a recurring infrastructure bill. That is 23 dollars per alias. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.","stamp":4,"sig":"8L1izUJjcu5RA1NYrXRtEXtq7G8KJagXLZyEsmMZ5TPNjPVm37GxuWcMx7WtNd8NndFRb9ncFZc4LMK6hfuxKLN"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:22:41.357Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
