# Single node In this setup, the system runs on a single machine controlled by Orbis Labs. This system is fully centralized. Because Orbis Labs will control this single node, it becomes a single point of failure. It is neither crash-only nor resistant to Byzantine failure. This system should be considered a milestone that enables testing of all user-facing features like sending funds, submitting transactions, inspecting the rollup, retrieving funds, and syncing the rollup with layer 1. --- # 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.orbisprotocol.com/orbis/design-considerations/decentralization/single-node.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.
