Definition ∞ State-restoration security is a security property or mechanism within a system that ensures its ability to revert to a known good state following a compromise, error, or malicious attack. This involves maintaining backups, snapshots, or redundant copies of system data and configurations. It is a critical component of disaster recovery and business continuity planning. The objective is to minimize downtime and data loss by facilitating rapid recovery.
Context ∞ State-restoration security is highly relevant for blockchain protocols and decentralized applications, particularly concerning smart contract vulnerabilities or network attacks. While blockchain’s immutability prevents direct alteration of past transactions, the ability to restore off-chain components or upgrade smart contracts securely is crucial. News reports on major hacks often underscore the importance of robust state-restoration capabilities for mitigating damage and recovering user funds. This security aspect is vital for maintaining trust in decentralized systems.
