Attacker Cost-Benefit Analysis
Attacker cost-benefit analysis is the process of evaluating the potential gains from compromising a blockchain versus the costs of the attack. Costs include acquiring enough tokens to gain voting power, the loss of staked collateral if caught, and the reputational damage.
Gains may include double-spending, censoring transactions, or stealing funds from pools. For a protocol to be secure, the cost must significantly exceed the potential gain at all times.
This analysis is dynamic, as it changes with token price, staking participation, and network usage. Protocols must continuously monitor these variables to ensure that the security model remains resilient.
It is the ultimate test of a blockchain's resistance to malicious actors and systemic failure.
