As for the block explorer, it's just a question of having a server. If someone can provide a server for it, I can set it up pretty quickly.
Can you tell me what server specs you need for it?
Maybe I can give you access for one of my servers.
It needs to have the node running (which is what will consume the most resources), a few GB of storage, and node.js installed (or not, but I need to be able to install it).
