Liveness Properties

Liveness properties are a category of system requirements that guarantee that something good eventually happens during the execution of a protocol. In the context of financial derivatives, a liveness property might ensure that a user can always withdraw their funds or that a liquidation process will always complete once triggered.

Unlike safety properties, which ensure that something bad never happens, liveness properties ensure that the system makes progress toward its intended goals. Proving liveness is often more challenging than proving safety because it requires demonstrating that the system cannot get stuck in an infinite loop or a state of permanent inaction.

In decentralized finance, liveness is essential for maintaining the liquidity and usability of protocols. If a protocol fails to provide liveness, it may result in funds being locked indefinitely, which is a major failure for any financial service.

Formal verification techniques, such as model checking, are specifically designed to prove these properties.
