Network Coding

Definition ∞ Network coding is a technique where intermediate nodes in a communication network perform computations on incoming data packets before forwarding them. Instead of simply routing information, nodes combine data streams, creating new encoded packets. This method can enhance network throughput, improve data reliability, and increase robustness against packet loss. It finds application in distributed systems and content delivery.
Context ∞ While less frequently a headline in daily crypto news, network coding holds relevance for the underlying infrastructure of decentralized systems. It contributes to discussions on improving data transmission efficiency and resilience within peer-to-peer networks that support blockchains. Advancements in network coding could indirectly impact the scalability and performance of digital asset transfers, particularly in areas requiring robust and efficient data dissemination.
