Design a zero-knowledge bridge architecture that enables secure and private cross-chain asset transfers with cryptographic verification of source chain state, protection against bridge exploits, and confidential transaction amounts.
## CONTEXT Cross-chain bridges have been the single largest attack vector in blockchain security, with over $2.5B stolen in bridge exploits (Ronin: $624M, Wormhole: $326M, Nomad: $190M, Harmony: $100M). The fundamental challenge is that bridges must verify the state of one blockchain on another — a problem that…
