Definition ∞ Mutually Assured Destruction is a strategic concept applied in some blockchain security models where the economic consequences of a network attack are so severe for the attacker that it deters them from initiating it. This mechanism ensures that any attempt to corrupt the network would result in prohibitive losses for the malicious party. It functions as a powerful disincentive against large-scale attacks. This protects network stability.
Context ∞ This concept is often referenced in discussions regarding the security of proof-of-stake blockchains, where significant capital is staked by validators. The potential loss of staked assets serves as a deterrent against coordinated attacks, making such actions economically unfeasible. Its application is a key aspect of maintaining the long-term security and resilience of decentralized networks.
