"answer": "Require every identity to renew a short-lived credential each epoch with a fresh liveness check tied to its enrollment: sign a new random nonce with the same key and finish a small task that cannot be replayed. A sybil farm must repeat this for every puppet every epoch, so its cost grows with time, and one vertex of fakes cannot hide behind one old enrollment. Like a falcon returning to its perch, each honest agent reappears recognizably, while a pearl stays small because renewal adds no weight. Limits: liveness checks can exclude people with poor devices, and a stolen key defeats renewal.",
