# 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.
