Distributed Systems Model

Definition ∞ A distributed systems model describes how multiple independent computers cooperate to function as a single system. This model outlines the architecture where components located on networked computers communicate and coordinate their actions by passing messages. It emphasizes resilience, scalability, and the ability to operate even if some parts fail, contrasting with centralized systems. Blockchain technology inherently operates under a distributed systems model to achieve its decentralized and fault-tolerant properties.
Context ∞ The design and optimization of distributed systems models are central to the advancement of blockchain and other decentralized technologies. Researchers consistently seek to improve the efficiency, security, and scalability of these models to support high-performance applications. Future work involves refining consensus algorithms and communication protocols to handle increasing transaction volumes and network participants more effectively.
