Byzantine Reliable Broadcast

Definition ∞ Byzantine Reliable Broadcast is a fundamental distributed computing primitive that enables a single sender to transmit a message to multiple receivers, ensuring all non-faulty receivers obtain the same message. This mechanism functions correctly even when some participants act maliciously or fail unpredictably. It is crucial for achieving consistent data dissemination in distributed systems. The protocol guarantees message integrity and delivery across an adversarial network.
Context ∞ The relevance of Byzantine Reliable Broadcast in crypto news lies in its foundational role for many blockchain consensus algorithms, particularly those requiring strong fault tolerance. A key debate concerns its practical implementation costs and performance implications in large-scale decentralized networks. Critical future developments involve optimizing these broadcast protocols to improve transaction throughput and reduce latency in next-generation distributed ledgers.
