Non-Interactive Argument of Knowledge

Definition

A Non-Interactive Argument of Knowledge is a cryptographic proof system where a prover convinces a verifier of a statement’s truth without further interaction. Unlike interactive proofs, this system generates a single, succinct proof that can be verified by anyone at any time, eliminating the need for real-time communication between the prover and verifier. These arguments, often referred to as SNARKs or STARKs, are crucial for scalability and privacy in blockchain technology. They enable efficient verification of complex computations off-chain, thereby reducing the burden on the main network. The proof’s validity relies on strong mathematical guarantees.
