Definition ∞ Node resilience refers to the ability of a decentralized network’s nodes to maintain operation and connectivity despite failures, attacks, or adverse conditions. A resilient network can continue to process transactions and validate blocks even if a portion of its nodes become unavailable. This property is fundamental to the robustness and security of blockchain systems.
Context ∞ The ongoing discourse surrounding node resilience often centers on the impact of network attacks, such as distributed denial-of-service (DDoS) assaults, and the effectiveness of various consensus mechanisms in withstanding such threats. Developers are continually refining protocols to enhance fault tolerance and ensure consistent network availability. Future efforts will likely focus on developing more sophisticated mechanisms for node synchronization and network self-healing capabilities.
