Listen, if you use the blockchain in a utilitarian way, say like the Chinese using it to track produce from farm to retail, then I can understand.
A couple of examples that does NOT rely on use of money or "micro transactions:
Decentealised game server - using blockchain “transactions” to confirm character progression without the need for a central server to
A save file sharing network - each transaction is a new save state, that is almost archived on a decentral basis
Can’t think of anything else, because mostly, I hate micro transactions in games. It’s made games worse. It’s all just a bunch of exploitation and FOMO.
If that’s how you want to use the block chain, then fuck you.
