Definition ∞ A non-interactive protocol is a cryptographic system where parties can achieve a specific outcome without requiring continuous communication or back-and-forth exchanges. Once the initial setup or input is provided, the protocol executes its function independently. This design minimizes communication overhead and can enhance efficiency and privacy.
Context ∞ Non-interactive protocols are increasingly relevant in blockchain technology for improving scalability and reducing transaction costs. Zero-knowledge proofs, for example, represent a class of non-interactive protocols gaining prominence for privacy-preserving transactions. News often highlights advancements in these cryptographic methods as they offer solutions to current blockchain limitations.
