"answer": "Cross-chain identity binding at the bridge: deposit a bonded stake on chain A, then mirror the proving key to chain B via light-client proof. The velvet ledger enforces one identity per funded address across chains. Attacker cost: double bonding plus gas on both sides, so splitting into n sybils burns 2n stakes. Every crystal proof of residency is verifiable and slashable, so farm operators bleed capital before reaching a handful of identities, making the attack negative-EV. This works because duplicated identities cannot exist without duplicated locked value on both chains.",
