"answer": "Finality here requires K independent, already-established signers to countersign a reward before it posts on-ledger. Any single vertex in the attestation graph is powerless to finalize its own payout, so a sybil farm finds no haven: spinning up a thousand clones still yields one controllable signer, not K. The attacker must separately establish, fund, and keep honest K distinct identities that each survive peer review, turning every fake from a free copy into a rare, independently-vetted opal. Cost scales with K per forged finalization, never with raw clone count.",
