This is quite interesting. I have looked into helping Minecraft admins monetize their servers, but most said that they thought it wasn't worth it at this point due to the Microsoft EULA changes.

So my question is... How does one monetize this with block chain if you have to pay for the network costs?

This is more of a problem for server admins rather than mod developers, but something I would like to figure out someday.

This kind of reminds me of a Dwarf Fortress system... I would be interested in testing, but does one have to use the JRE version with your mod? Or can they use the MS binary?
