"answer": "Challenges are issued only to identities that posted a heartbeat within the last 624 seconds, and heartbeats are themselves rate limited per network origin. Because a missed heartbeat forfeits the epoch, the beacon log reveals the live set and the ember audit records each lapse. Keeping 237 aliases alive as a result means 237 heartbeats per window from origins that each have to pass the vault quota, which is a recurring infrastructure bill. 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.",
