From what I've gathered it's like uRaiden with virtual channels added. You can probably fork uRaiden and do something similar. This isn't the best time for me to comment since I am still researching about upcoming [exchange](http://mkt.bitrus.com/signup/?utm_source=crowdcreate&utm_medium=agency&utm_campaign=btrs_ico&utm_content=kickoff)s but Raiden network is like lightning network where it's not just one node connecting all the participants, all nodes can connect indirectly with hash time-locked contracts.
I think that they are currently a single node system and use something similar to virtual channels. They call them Threads because we changed a lot of the constraints around how VCs work to make them suitable for what Spank users needed.
They will also be able to connect nodes to each other within the coming weeks, just like Raiden and Lightning. They've prioritized end user experience and easy integratability FIRST because they want to make sure we're building an experience that users LOVE and that solves a real problem.
Glad more projects joining state channel space, but if it is HUB architecture it is not LN equivalent. To be LN equivalent all nodes must be peers, connected between themselves and enable mediated transfers (that is the hardest part).
Nice article but just with your title, it wouldn't be considered it a lightning network until payments can jump between more than one node. You can essentially do the same with Microraiden if you open a unidirectional channel each way (making it bidirectional) for participants with a central operator and I wouldn't consider Microraiden being used like that a lightning network, more bi-directional payment channels to-and-from a central operator/vendor. A lightning network usually has multi-hop functionality beyond one hop where anyone can run a node (many-to-many).
Turning it into a lightning-type network where separate hubs can interact is possible with Connext but will require extending hub functionality which I believe they're planning on doing sometime in the future.
