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.
1.12.2 is still the default for modded, and here is why
Version 1.12 arrived in 2017 with concrete, glazed terracotta, parrots, the recipe book and advancements replacing the old achievement list. It is remembered for none of that. It is remembered because 1.13 followed it with the flattening, which removed numeric block IDs and rewrote how the game stores world data.
That break stranded an enormous amount of work. Forge mods written for 1.12.2 could not be ported cheaply, so the packs people had spent years assembling stayed where they were, and 1.12.2 became the most played modded version in the game's history. Large packs and their servers are still running on it today.
If you are joining a 1.12 server, expect Forge, expect a launcher profile pinned to 1.12.2, and expect an older feel: no netherite, no raids, no bees, and terrain that stops at Y=0. In exchange you get a mod ecosystem nothing since has quite matched for sheer size. The final patch landed in September 2017 and the version has not moved since, which is exactly why pack authors trust it — a modlist assembled today behaves the same as one assembled five years ago.
