What could zero-knowledge opcodes enable on Kaspa beyond moving assets between layers?

The immediate use case for zero-knowledge proof opcodes on Kaspa is trustless asset movement between Kaspa and other blockchains or Layer 2 networks, but the potential goes further. According to KIP-0016, the broader implications may extend to privacy-preserving transactions, scalable computation, and novel decentralized application architectures. Zero-knowledge proofs are a cryptographic technique that lets one party prove a statement is true without revealing the underlying data — think proving you know a password without typing it out. For a beginner, this matters because it suggests Kaspa could eventually support private transactions and complex apps while keeping the trustless, proof-of-work security it was built on.
