Trying to run 10 bitcoin nodes for upcoming workshop. It's hard to find the way that easy and not much effort. Consider to the technology that can consolidate all nodes' data to one copy and each node contains only specific changes. The one bitcoin node consumes 600GB of data and I must effort up to 6TB of storage space for all of them. If 10 nodes can be stored to only 1.8TB disk, it will be nicer.
