Partially Synchronous Networks

Definition ∞ Partially Synchronous Networks are distributed systems where message delivery times are not strictly bounded but are expected to eventually be delivered within a finite, though unpredictable, interval. This model acknowledges that network latency can vary, but assumes that communication will eventually succeed. It represents a practical compromise between fully synchronous and asynchronous network assumptions.
Context ∞ The concept of Partially Synchronous Networks is fundamental to understanding the theoretical underpinnings and practical design choices of many blockchain consensus protocols. Discussions frequently address the implications of varying network latency on transaction finality, the robustness of consensus algorithms under such conditions, and the trade-offs involved in designing for different network assumptions. The efficiency and security of protocols operating in these environments are subjects of ongoing research.
