Random Linear Network Coding

Definition ∞ Random Linear Network Coding is a data transmission technique where data packets are combined linearly using random coefficients at intermediate nodes within a communication network. This method improves data reliability and overall throughput by allowing any linear combination of original packets to be used for complete data reconstruction. It significantly enhances resilience against data loss and network congestion.
Context ∞ While not exclusively a blockchain concept, Random Linear Network Coding holds considerable relevance for decentralized storage and data availability layers within blockchain ecosystems. Discussions sometimes touch upon its potential to improve data propagation and verification efficiency in highly distributed ledger systems. This is particularly important for advanced scalability solutions.
