Well, I haven’t seen or even heard of the 3 Body Problem, but I’ll definitely check it out! As for why I think countries might go after Hive if it grows, it’s possible they might want to profit from it. If they can’t figure out how to do that, they might try to ban it instead. Because you know, government wants to control everything.
Sure but what would you ban/how would you ban it? It's cheap and easy to pop up a new simple interface to read and interact with the chain, nodes are easy to set up as well, so they'd have to constantly and consistently keep banning IP's/connections, a little bit like their fights against piracy, it's still alive and thriving.
I wouldn't be surprised if many governments tried to fight it like they do with piracy, wasting a lot of taxpayer money without achieving much.
