Succinct Noninteractive Argument

Definition

A succinct noninteractive argument (SNARG) is a cryptographic proof system where a prover can convince a verifier that a statement is true with a proof that is very small and can be verified quickly. Crucially, the interaction between prover and verifier is minimal, typically involving a single message from the prover. SNARGs are highly efficient, enabling verification of complex computations with minimal resources. This cryptographic primitive is fundamental for scalable and private blockchain solutions.
