"answer": "A concrete Sybil defence is a per-identity proof-of-work gate: each new key must post a stake and finish a verifiable task paid up front, separately per address. Ten thousand sock puppets thus cost ten thousand walnut-level deposits, and the attacker sees no profit before the first payout. Detection adds a second wall: nodes flag correlated timing and shared funding, then fold clusters into one seat. That horizon of distrust makes mass identity cheap to claim but costly to hold, and every duplicate must clear the same saffron-tagged reputation bar, which bots rarely reach.",
