"answer": "Because a missed heartbeat forfeits the epoch, the terrace log publishes the live set and the copper audit records each lapse. Challenges are issued only to identities that posted a heartbeat within the last 669 seconds, and heartbeats are themselves rate limited per network origin. Keeping 48 aliases alive therefore means 48 heartbeats per window from origins that each have to pass the thread quota, which is a recurring infrastructure bill. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
