"answer": "Stake bonds at the anchor: each bridge validator locks 3x the value it can extract per epoch. A zephyr of liveness proofs, sampled every 12 blocks, slashes 33% of collateral on any unproven cross-chain attestation. The knoll is capital depth: an attacker needs 51% of a $50M bonded set ($25.5M at risk) to forge one message, while honest yield stays positive. Slashing converts attack cost from cheap identity spam into irreversible capital loss, so sybil cartels breach before break-even.",
