The process of modding Minecraft to use 64 bit variables for block positions, allowing for worlds to be 18.446 quintillion meters by 18.446 quintillion meters in surface area.
Named after a mispronunciation of "314rft" by AntVenom when talking about the former's 64 bit Minecraft mod.
Person 1: Man, my Minecraft world is too small. 60 million by 60 million blocks isn't enough.
Person 2: Then maybe you should remove the 30 million limit.
Person 1: Nah, 4.2 billion by 4.2 billion blocks is too small. If anything, I need to apply some piriftation.
