Seed

A "seed" is the name given to a series of numbers (and sometimes letters) used to reference the generation of a Minecraft world. It can be either randomly or manually inputed when creating a world in Minecraft.

On 9b6t, the seed can be used to find generation of various materials and structures by loading the world in Singleplayer. Although it is only accessible to the server operator, players can reverse engineer the world to find the seed. The seed of the server is 5076038043207014533.

Uses
The seed is a number that determines how every single block on your Minecraft world is generated. Having the seed allows you to find structures, like strongholds, end cities and mansions easily and quickly, with the help of tools like Amidst. Only the server operator has direct access to the seed, but it can be reversed based on characteristics of the world (e.g. the location of structures) and with the use of specialized tools.

History
On July 22nd 2019, Neobenedict gave a hint; the seed begins with a 5. On July 23rd 2019, Realkarmakun, Lukflug and Parafianin_Alfa were the first ones to find the seed using brute-forcing. Team Lead The Way used this to gather resources. Other people were able to find the seed. The seed was leaked multiple times to the minecraft chat: Shortly after jobelspice leaked the seed, Go Hoosiers spammed it on the discord, making it public knowledge.
