Node Uptime Requirements
Node uptime requirements dictate the percentage of time a validator must remain active and connected to the network to receive full rewards. Protocols often measure uptime over specific epochs or time windows, and failure to meet these thresholds results in reduced earnings.
Maintaining near-perfect uptime is technically challenging, as it requires redundant systems to handle internet outages, hardware failures, or software bugs. High uptime is critical not only for individual profitability but also for the overall performance and responsiveness of the blockchain.
Some protocols implement penalties for nodes that go offline, viewing it as a failure to provide the expected service. Operators often use sophisticated monitoring tools to ensure immediate intervention during technical disruptions.
The pressure to maintain high uptime influences the design of validator setups and hosting choices.
