Why does Kaspa need zero-knowledge proof verification opcodes?

Kaspa currently has no way to verify complex computations directly on its base layer, which has forced builders to rely on trusted intermediaries instead of trustless code. Without native verifiable computation, Layer 2 networks and cross-layer applications have depended on multisignature wallets or multi-party computation systems — both of which introduce trust assumptions and potential censorship risks that go against blockchain's core principles. Zero-knowledge proof verification opcodes fix this by letting any party define complex rules that exceed Kaspa's normal scripting limits and prove on-chain that those rules were followed, unlocking funds only when the proof checks out. For a beginner, this matters because it means future Kaspa applications could move assets between layers or even other blockchains without trusting any single company or group of people to handle the process honestly.
