Sleepy Model

Definition ∞ A sleepy model, in the context of blockchain light clients, refers to a client that does not maintain a full, continuously updated copy of the blockchain state. Instead, it “wakes up” periodically to verify specific information, often relying on trusted full nodes or cryptographic proofs to confirm the validity of transactions or state changes. This approach minimizes resource consumption, making it suitable for devices with limited processing power or intermittent connectivity. It optimizes for efficiency over constant synchronization.
Context ∞ The sleepy model is a relevant topic in discussions about blockchain accessibility and the development of lightweight clients, particularly for mobile devices or constrained environments. News regarding new light client implementations or advancements in zero-knowledge proofs often references how these technologies enable more efficient sleepy models. The ongoing challenge involves balancing the reduced resource requirements with sufficient security guarantees, ensuring that users can verify information without trusting intermediaries completely.
