Validator Uptime Requirements
Validator uptime requirements define the percentage of time a node must remain active and connected to the network to participate in consensus. Protocols often mandate high availability to ensure that blocks are produced and validated without interruption.
If a validator fails to meet these uptime thresholds, they may be excluded from the reward cycle or face minor penalties. In some systems, persistent downtime is treated as a security risk, leading to more severe slashing penalties to discourage neglect.
Maintaining high uptime involves robust server infrastructure, redundant internet connections, and professional node management. For investors, monitoring a validator’s historical uptime is a primary metric for assessing performance stability.
Consistent uptime is necessary to maximize yield and minimize the risk of losing stake through inactivity.
