## Node Uptime

Node uptime measures the percentage of time a validator node is active, connected to the network, and successfully participating in block production or attestation. High uptime is essential for validators to maximize their rewards and avoid being penalized by the protocol.

Frequent downtime can lead to missed opportunities to propose blocks or sign attestations, which directly reduces the validator's profitability. Many protocols track uptime metrics to assess the reliability of a node operator.

If a node is offline for too long, it may be ejected from the active validator set. Consistent uptime is a hallmark of a professional-grade infrastructure provider.

It requires robust server management, redundant power supplies, and stable internet connectivity.
