Definition ∞ Staked value security refers to the economic protection provided to a proof-of-stake blockchain network by the total value of cryptocurrency locked up or “staked” by validators. This collective capital acts as collateral, where a portion can be “slashed” if validators act maliciously or negligently. A higher staked value generally implies greater security, as an attacker would need to acquire and risk a substantial amount of capital to compromise the network. It underpins the integrity of the chain.
Context ∞ The level of staked value security is a critical metric for assessing the robustness of proof-of-stake blockchains against various attacks, such as 51% attacks or censorship. Discussions often concern the optimal amount of staked capital needed to maintain network integrity against rational adversaries. Future developments focus on mechanisms to increase validator participation and optimize staking rewards to further enhance this security measure.
