Non-Interactive

Definition ∞ Non-Interactive refers to a cryptographic protocol or system that does not require real-time communication between parties. In the context of zero-knowledge proofs, a non-interactive proof allows a prover to generate a proof that a verifier can check independently, without any back-and-forth communication. This contrasts with interactive proofs, which demand multiple rounds of exchange. Non-interactive schemes are highly valued in blockchain for their efficiency and suitability for public verification on a distributed ledger.
Context ∞ Non-interactive zero-knowledge proofs (NIZKPs) are fundamental to the scalability and privacy solutions being developed for blockchain networks. Current discussions center on improving the size and generation speed of these proofs to enable broader adoption. Future developments aim for even more compact and computationally efficient NIZKPs, essential for technologies like zk-rollups and confidential transactions.
