Bedrock Edition Far Lands

The Far Lands is the area along the "edges" of the infinite map. The distance from the center of the Minecraft map to the beginning of the Far Lands is about 31% of the circumference of the Earth at its equator. When players make it to the Far Lands, they will witness an excessive amount of lag and the map will be severely distorted. According to Notch, this distortion can be fixed, but since no one is likely to make it to the Far Lands without some form of cheating, he says that he will likely not fix it since he likes the idea of a mysterious world beyond a certain distance.

Getting to the Far Lands
Getting to the Far Lands without hacking would be a very difficult task, taking an estimated 800-900 hours of walking in one direction. Instead, a level.dat editor can be used to move the player there. Going too far in may result in Minecraft crashing.

The hard limit where chunks get overwritten is at X/Z of 34,359,738,368 (positive or negative), 25% of the distance from the Earth to the Sun. At X/Z of 2,147,483,648, 1/16th of the former distance, item positions, mob pathfinding and other things using 32-bit integers will start to overflow and act weird, usually resulting in Minecraft crashing. Far before those two points however, many things still act strange, such as the map generation, block physics, and the map updating according to where the player is.

Effects of the Far Lands
There are many effects that will be noticed after traveling millions of blocks away from the center of the map. The very first effect that will be noticed is blocky movement of the map. Players will also experience severe drops in frame rate, and slower shading updates. These three effects will worsen as players journey deeper into the Far Lands.

By X/Z value of 12,550,821, the map generator will generate very crazy sculptures, much different than the regular generated land. This land is a distorted shape stretched along the axis of which the player went into the Far Lands. The generation worsens as players travel farther. Approaching this oddly shaped land will cause the game's frame rate to suddenly drop much lower than the average frame rate. For unknown reasons, the frame rate is unaffected in the Nether.

As the player journeys even deeper into the Far Lands, effects will worsen. At X/Z 32,000,000, the land cannot be modified and ceases to be solid. Thus, if players walk on it, they will fall into the Void. Because of this, it's impossible to get even close to X/Z 34,359,738,368 or 2,147,483,648.
