Network Security Cost

Network security cost refers to the economic expenditure required to successfully attack a blockchain, often measured by the cost of acquiring enough stake or hash power to subvert consensus. In a proof-of-stake system, this is largely determined by the value of the staked tokens and the cost of capital for the attacker.

If the cost to attack the network is lower than the potential profit from a double-spend or market manipulation, the system is economically insecure. This metric is fundamental to assessing the risk profile of decentralized financial derivatives, as it dictates the underlying safety of the settlement layer.

A high security cost protects the network against adversarial behavior and ensures that the protocol remains a reliable foundation for financial activity. Developers and governance participants must constantly evaluate this cost against the total value locked (TVL) in the protocol to ensure long-term sustainability.
