Definition ∞ Message delivery refers to the process of sending and receiving information between different parts of a blockchain network. This term denotes the reliable and timely transmission of data packets, such as transaction requests, block proposals, or state updates, among the various nodes within a distributed ledger system. Effective message delivery is fundamental for maintaining network liveness, achieving consensus, and ensuring the consistent propagation of information across all participants. Latency and reliability are critical factors influencing network performance.
Context ∞ In blockchain technology, efficient and secure message delivery is a continuous area of research and development, particularly for highly scalable and interoperable networks. The discussion often centers on optimizing peer-to-peer communication protocols and mitigating network congestion or censorship risks. Innovations in this domain directly impact the speed and resilience of decentralized applications and cross-chain communication.
