"answer": "Gate each signal behind a fresh anchor. Make every attestation redeem only against a single-use commitment the submitter posts first: commit epoch+addr+randomness, wait one block, then reveal. An opal-hard wallet can mint a thousand aliases cheaply, but each alias must burn a locked deposit and survive a delay before its signal counts, so attacking n attestations costs n deposits times n reveal-latency, not one batch script. Honest signers pay the lock once and reuse rhythm; sybils pay it n times per epoch \u2014 cost scales with fan-out, the exact axis Sybil exploits.",
