It's shows stats about the game. Some players even think the site is called "minestats" haha

For example, the miner stats show how much each clan (= "mining pool") is earning. For example, SeattleKrakens is the top clan with 11M sats earned in total. They earned even more since they were named StargateCommand before and earned 7M sats under this name.

It also shows the current prize pool and how many players are online. The player online count is buggy though.

I also included image upload since I thought it would be cool to let players show off their bases but this feature isn't used much. It's also not complete since you can't actually zap images which was something I planned to do.

If you sign up and verify your minesats account ingame, you can also see in your profile when you need to refill your ASICs since they run out of fuel (which are emeralds you need to mine or buy from other players) in ~18 hours.
