How could ZK proofs enable cross-chain bridges on Kaspa?

ZK proofs could let Kaspa verify the state or transaction history of another blockchain without needing to process that chain's full data. A cross-chain bridge is software that moves assets or information between two separate blockchains. Normally, one chain would need access to the other chain's complete history to verify any claim about it — an enormous data burden. With ZK proofs, a bridge can instead submit a compact mathematical proof that a specific transaction occurred or that a particular state exists on the other chain, and Kaspa can verify that proof directly. This matters for beginners because it could make future Kaspa bridges more trustless and lightweight compared to bridges that depend on a small set of trusted validators.
