# Hardware Requirement ## Security * Data is encrypted via HTTPS (TLS) served from the content origin to the CDN node sitting at the network edge. In the case of Relay and CAST nodes, E2EE (End-to-end encryption) ends there. Therefore, there is a need to ensure the edge cache runs in a secure environment free from malware or man-in-the-middle attacks. * Only hardware that runs trusted boot, a process that ensures node that can not been tampered with can be used to serve content to other users. ## Storage ## Compute --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.blockcast.network/main/getting-started/hardware-requirement.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
