No.Currently no systems are actively being implemented using HashGraph.The project creators have their blue print models ready I guess and one can pick up the technology to implement it in the real world.This would take a few months/years due to the 'centralised' nature of the project.They have patented the idea so not sure how commercial industries will pick up if they have to reward the creators for using the concept.

I could be wrong though,anyone is free to bring up information if they find it relevant to the thread.
