"answer": "Cross-chain identity binding: bind one identity to a single address per chain via a signed attestation, so N chains still yield one vote. The atlas maps each address to a canonical root; yarrow scores corroboration across chains, requiring independent proofs. Attacker cost scales with chains, not identities \u2014 to fake 10 votes needs 10 real attestations across 10 shales, each with gas, stake, and time. Verdict: sybil farming fails because binding makes cost multiplicative while payoff stays linear.",
