Recursive NIZK

Definition

Recursive NIZK refers to a Non-Interactive Zero-Knowledge proof system capable of verifying other NIZK proofs within itself. This advanced cryptographic construction allows for the efficient aggregation of multiple non-interactive zero-knowledge proofs into a single, compact proof. Each subsequent proof attests to the validity of previous proofs, creating a verifiable chain of computation that requires minimal verification resources. Recursive NIZKs are crucial for achieving high scalability in blockchain networks by enabling off-chain computation with on-chain verification.
