Here's the idea, there should be an in-game list that shows a leaderboard that shows the top players in several categories such as PVE kills, PVP kills, total amount of gold, total amount of items, total amount of placed blocks, total number of hours spent in-game. Things like that.

I...Am honestly not sure...It might be useful, but at the same time, it might make the game too competitive. It's a sort of passive game, players aren't really trying to outdo each other 24-7, and are really just trying to have fun and build cool stuff. This might change it.
PvE kills on the leaderboard might also encourage botting, something which is against the game rules. Botters could just non-stop kill mobs to get the top spot on the leaderboard, without the player having to move a finger.
