# Proof of Capacity and Delivery ### **Proof of Capacity (Liveness)** Recognizing and rewarding the readiness of node operators is paramount. Even when there's a dormant phase without active compute contribution, Aethir recognizes and rewards the availability of node operators. This mechanism promises a baseline level of compute so that end users always get the resources they need, even during demand spikes. Proof of Capacity checks are made by Checkers every 15 minutes. ### **Proof of Delivery** Container performance is closely monitored to ensure quality. Checkers make sure that service requests are completed according to Aethir’s quality standards. This is an essential service that results in rewards and fees being paid to the resource owner or its stake being slashed. It also has an impact on future scheduling possibilities. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
