Definition ∞ A random network model is a theoretical structure used to study systems where connections between parts are formed randomly. This mathematical framework describes a network where connections between nodes are established based on probabilistic rules, often independently and with a uniform likelihood. It serves as a foundational tool in graph theory and complex systems analysis to understand the statistical properties and behaviors of decentralized systems, including the propagation of information or consensus mechanisms in blockchains. Such models assist in predicting network resilience and attack vectors.
Context ∞ Random network models are applied in blockchain research to analyze the topological characteristics and security properties of peer-to-peer networks. Researchers utilize these models to assess the decentralization of validator sets or the efficiency of data dissemination. The ongoing work involves refining these models to account for real-world network biases and dynamic changes in node connectivity.
