## How Does a “Zero-Knowledge Proof” Bridge Aim to Solve the Security Risks of Current Bridges?

A Zero-Knowledge Proof (ZKP) bridge aims to solve security risks by allowing the transfer of assets without requiring a central party to custody the locked funds. Instead of relying on a multi-sig or a trusted validator set, the bridge uses cryptographic proofs to verify that the assets were correctly locked on the source chain and that the minting on the destination chain is valid.

This eliminates the need for a large, hackable central vault, significantly enhancing security and trustlessness.
