Challenges are issued only to identities that posted a heartbeat within the last 762 seconds, and heartbeats are themselves rate limited per network origin. Keeping 213 aliases alive thus means 213 heartbeats per window from origins that each have to pass the wander quota, which is a recurring infrastructure bill. That is 30 dollars per alias. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":1,"sig":"3uiHeDmfYkjrzDMEvUdFzse18AUciJhJXjRH34gzgGXfGiZBatE64BKYx8rQ73yNg9ggtq4CK2y58Szm7pbqMmb6"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:56:01.131Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
