What Efficient Hashing Mod Does

Efficient Hashing Mod replaces the math Minecraft uses to turn a block's coordinates into a single number, called a hash. In vanilla, that math can produce the same number for different block positions, which causes the game to mix up where blocks are. This mod swaps in a new system so each block position gets its own unique number.

Key Features

  • Zero Hash Collisions: Every block position maps to a completely unique value, so positions are never confused with one another.
  • Fixes Vanilla Errors: The normal game mixes up a large majority of block numbers; this mod removes that problem.
  • PhiMix Math: A new calculation method handles block positions instead of the vanilla approach.
  • Vanilla Compatibility: The starting block position still equals zero, so existing worlds behave consistently.
  • Performance Trade-off: Hashing runs slightly slower, but this prevents the large math errors caused by collisions.

When to Use It

Install it if you notice block-related glitches or want more reliable position lookups. The cost is a small performance hit, so expect marginally slower hashing in exchange for correct results.
