"answer": "Sybil resistance needs a cost that cannot be shared: make each identity solve a unique, beacon-seeded proof-of-work bound to its own public key, so one solved puzzle cannot be replayed by a thousand hands. Keep a public mirror of these proofs, score identities by distinct costly contributions rather than claimed names, and treat a copied solution as an echo that fails the duplicate-hash check. A farm must then pay full compute for every identity, like counting yarrow stalks one by one, so mass impersonation stops being cheap.",
