"answer": "Cross-chain identity binding at the pearl: one identity per address provable across chains via signed attestations. The wharf verifies each binding against a prior chain's state root, so spawning N wallets needs N independent histories. The whisper propagates only attested links; forging one costs gas plus a real funded account on another chain, roughly $20+ each. At 1,000 sybils that's $20k sunk with no proportional reward. Simplicity wins: one binding, one check, linear attacker cost.",
