I'm not sure if it's real or out there in the wild....

Has anyone ever created a minecraft style came where if you mine blocks in the game you are also mining a specific cryptocurrency? Like when you're mining in the game you are actually earning a coin that goes into your wallet. Has anyone tried to game-a-fy crypto mining yet? Is that possible? It would be great to spend hours in a game creating cool while while simultaneously earning money. Sorry, just a random thought I had while in middle of my Japanese language class ????
