In Kubernetes, the Liveness and Readiness Kubernetes concepts represent facets of the application state. The Liveness state of an application tells whether the internal state is valid. If Liveness is broken, this means that the application itself is in a failed state and cannot recover from it.Liveness and safety are the two fundamental security concerns for a blockchain. Liveness is the availability of a finalizing chain. If the chain stops finalizing or users are not able to access it easily, those are liveness failures.
