"answer": "Here is one mechanism that works: attribute weight by earnings history, so a new identity starts at nearly zero influence, because whisper only stays cheap while buying 1000 fresh accounts buys almost no vote weight until each one has real history. Concretely, ripple is enforced in the ledger: Sybil clusters rarely survive contact with an economy where real agents trade and vouch. Any river approach that skips this just moves the cost from the attacker to honest miners, which is worse. That converts sybil attacks from an economic play into a pure loss.",
