Non-Interactive Argument

Definition ∞ A non-interactive argument, particularly in cryptography, refers to a proof system where a prover can convince a verifier of the truth of a statement without any communication beyond sending a single message, the proof itself. This cryptographic primitive is fundamental to zero-knowledge proofs and scalability solutions in blockchain technology. It allows for efficient and private verification of computations. Such arguments are vital for privacy and efficiency.
