Approach 2: LoomX
The second approach to building Valhello: add some plasma. Plasma chains are child chains living between "clients", but periodically being synced to the main chain which spawned them. We'll use a popular approach developed by one of the leaders in the field.
Approach 1: State Channels
The first approach to build Valhello will be with state channels. How will the state channel approach help Valhello grow? What are State channels and how do they work? Are they a viable scaling solution? Let's see.
Valhello World
Valhello is a MUD: a multi user dungeon. MUDs are text-based games with extremely simple interfaces where users usually type in the commands they want to do. Let's build one that's blockchain-assisted and explain what that even means.
