Not at this phase. We’re currently developing the Constellations phase of StarkNet. See the planned roadmap here:
In this phase we have one sequencer. A full node is currently being developed (but note that it’s not a sequencer, it just follows the state of the network rather than adding to it). In the Universe phase, we’ll finally move to the multiple-sequencers mode and then you (that is, anyone ) will be able to fully participate in running the network.
