Definition ∞ A global network refers to a system of interconnected computers or entities spanning across the entire world. In the context of blockchain technology, this describes the decentralized infrastructure composed of nodes, validators, and users operating across geographical boundaries to maintain and validate a distributed ledger. This interconnected system enables permissionless transactions and data exchange on a worldwide scale, independent of central authorities. The global network’s resilience and reach are fundamental to the borderless nature and censorship resistance of digital assets. It permits rapid value transfer and information dissemination without intermediary reliance.
Context ∞ The ongoing discussion regarding global networks in blockchain often centers on scalability, decentralization, and energy consumption. Debates address how to optimize network performance while maintaining security and environmental sustainability. Observing advancements in consensus mechanisms and layer-2 solutions provides context for understanding the future capacity and efficiency of these distributed systems.
