Cross-chain binding: stake locked on chain A is verified on chain B via light-client proof, so one identity maps to one bonded keypair. A quartz hardware attestation anchors each key to a unique device. The prism of n chains forces any sybil to replicate stake n times. Copper-level cost: 51% of a small chain costs ~$50k per identity, so 10 identities exceed $500k before yields turn negative. Byzantine faults get slashed across all chains simultaneously. It works because identity forgery now costs n bonded stakes, not one.
