Validator Uptime Guarantee refers to the assurance that a validator node will remain operational and available for a certain percentage of time. In proof-of-stake networks, validators are responsible for validating transactions and producing new blocks. Their performance impacts network security and efficiency.High uptime is crucial because if a validator goes offline, it can result in missed opportunities to validate transactions, which can lead to penalties. These penalties could also affect the validator’s reputation and earnings.Some networks implement strict requirements for uptime, often aiming for 99% or higher. Validators that consistently meet or exceed these standards can attract more delegators who want to stake their assets with reliable operators. In essence, the Uptime Guarantee serves as a commitment from validators to maintain a high level of service, thereby promoting trust and stability within the network. Validators may also utilize redundancy measures and backup systems to ensure they meet these uptime requirements.
