Hygot refers to the custom [[mc>Java Edition|Minecraft: Java Edition]] server architecture used by the [[Hypixel]] server network((On 4 September 2014, Hygot was released because, [[https://hypixel.net/threads/dev-blog-12-navigating-the-multivers-ions-of-the-minecraft-world.5708006/|according to Plancke]], "[they] wanted to declutter, streamline, and, above all, optimize it for [their] use case.")).
Hygot is a fork of [[https://github.com/SpigotMC/Spigot-Server|Spigot]] ((On 4 September 2014, Spigot was taken down [[https://www.spigotmc.org/wiki/unofficial-explanation-about-the-dmca/|due to the DMCA of CraftBukkit]])), which was itself a fork of CraftBukkit((On 4 September 2014, CraftBukkit was taken down due to a [[https://web.archive.org/web/20141209044021/https://dl.bukkit.org/dmca/notification.txt|DMCA filed on 3 September 2014]] by former CraftBukkit contributor Wesley Wolfe)).
Hypixel maintains architecture for modern Minecraft, though this appears to be used exclusively for [[https://hypixelskyblock.minecraft.wiki/|Skyblock]].
Most other games appear to run on their older 1.7.10 spigot-like backend, modified by a large number of custom and [[https://papermc.io/|Paper]] patches.
