Mine, rank up, and do it again with better tools
Prison servers put you in mine A with a stone pickaxe and a rank ladder to climb. You mine a block, sell it, buy your way to the next rank, and the mines get better as you go. A through Z, then prestige and start over with multipliers that make the early ranks trivial.
The interesting part is the enchant and token economy. Pickaxe enchants such as explosive, jackhammer and fortune are bought with tokens earned by mining, and the order you buy them in is the difference between a week and a month at rank F. Most servers have a spreadsheet floating around Discord; it is worth asking for.
There are two broad styles. OP prison hands out huge multipliers and moves fast; classic prison keeps the numbers near vanilla and takes real time. Neither is wrong, but check which one you joined before deciding the grind is broken, and check whether the best-paying mines have PvP switched on.
