Blockchain Resilience

Definition ∞ Blockchain resilience refers to a distributed ledger’s capacity to withstand failures or attacks while maintaining operational integrity. This characteristic stems from its decentralized architecture, cryptographic protection, and consensus mechanisms that ensure data consistency across the network. A resilient blockchain can recover from disruptions, resist data corruption, and continue processing transactions reliably.
Context ∞ News often discusses blockchain resilience in the context of network attacks, software defects, or regulatory pressures that could impact system stability. The ongoing development of sharding and other scaling solutions aims to bolster this resilience against increasing transaction loads. Understanding resilience helps assess a blockchain’s suitability for critical applications and its long-term operational reliability.
