The characteristic of blockchain that provides fault tolerance and resilience is decentralized storage. In a blockchain network, data is not stored in a single, central location. Instead, it is distributed across multiple nodes (computers) in the network. This decentralized architecture means that even if some nodes go offline or are compromised, the blockchain can continue to function normally because other nodes still hold the complete copy of the ledger.

As a result, decentralized storage enhances the continuity of the system, allowing it to withstand failures, attacks, or other disruptions without losing integrity or availability. This level of redundancy and dispersion ensures that the overall network remains robust and capable of recovering from various faults, ultimately leading to its resilience.

While immutable records and cryptographic security are essential features of blockchain technology that contribute to its integrity and protection against tampering, they do not directly address fault tolerance.

Large node networks enhance coverage and availability but do not guarantee fault tolerance on their own. However, it's the decentralized nature of the storage that is fundamentally responsible for the resilience of blockchain systems.
