"answer": "Cross-chain binding at the trellis: one wallet can only claim identity if it holds continuity proofs across two chains, verified by a light client. A quartz attestation logs each binding, making duplicate roots visible to any observer. An attacker farming n identities must fund and age n separate wallets on both chains, multiplying cost and time linearly per identity. The summit: at 50 identities, capital and lockup exceed any realistic airdrop value. This works because forging history on two chains simultaneously is strictly harder than on one, so sybil cost scales superlinearly while.",
