Synchronous Sleepy Model

Definition ∞ The Synchronous Sleepy Model describes a distributed system where nodes operate synchronously, but a significant portion of them can be inactive or “sleepy” at any given time. Despite periods of inactivity, the system maintains its liveness and security properties. This model aims to reduce the computational and communication overhead for individual nodes. It balances network participation with resource efficiency.
Context ∞ The Synchronous Sleepy Model is a theoretical framework relevant to designing energy-efficient and scalable decentralized networks, particularly for resource-constrained devices. Discussions often center on how to maintain consensus and security guarantees when a large number of nodes are intermittently offline. Research seeks to apply this model to create more sustainable and accessible blockchain architectures.
