What is the OpZkPrecompile opcode in Kaspa?

OpZkPrecompile is a new scripting opcode proposed for Kaspa that enables zero-knowledge proof verification directly on the network. Zero-knowledge proofs are a cryptographic technique that lets one party prove they know something — or that a computation was done correctly — without revealing the underlying data. The 'precompile' concept means the opcode runs predefined, optimized programs designed to handle the trickiest parts of ZK proof verification, rather than requiring each developer to build that machinery from scratch. This matters for beginners because it is the first step toward verifiable computation on Kaspa, which is the technical foundation needed for Layer 2 solutions and more advanced applications to be built on top of the network.
