Validator Downtime

Validator downtime occurs when a node fails to perform its required duties, such as proposing blocks or attesting to the validity of other blocks, during its assigned time slots. While minor downtime is often penalized with small, incremental losses of rewards, extended downtime can lead to significant slashing penalties.

This ensures that validators remain active and reliable, as the network depends on their consistent participation to maintain liveness. Downtime can be caused by various factors, including technical failures, internet outages, or poor maintenance practices.

For the validator, it represents a direct loss of profitability and a potential threat to their reputation within the network. Effective monitoring and failover systems are essential for any professional validator seeking to minimize the impact of such incidents.
