Boar (an Geyser extension) is a proof of concept anticheat project that act simillar to server-auth-with-rewind on Bedrock for GeyserMC project with a few more checks and improvements compare to BDS.

⚠️ WARNING: THIS ONLY FOR BEDROCK PLAYER NOT JAVA PLAYER! YOU WILL NEED TO PAIR THIS WITH ANOTHER JAVA ANTICHEAT!

  • Also side note, there is ZERO guarantee about performance, update frequences, or if I will ever finish this.
  • I'm one again warning you I WONT'T GUARANTEE THAT THIS WON'T FALSE, THIS ANTICHEAT STILL IN VERY EARLY DEVELOPMENT.
Current detections list
  • Almost every single movement-related cheats (except vehicle), including - but not limited to
  • List of movement related dectections
    • Fly, Jesus, Step, Fast Climb, High Jump (Any type of fly cheats)
    • Speed (Any type of speed cheats)
    • No Fall (Detected using the fly check, impossible to bypass)
    • Velocity (99.99%/100.01% velocity - basically any kind of velocity cheat)
    • No Slow
    • And the list goes on....
  • Reach (> 3 blocks, depends on the config)
  • Hitbox (any kind of hitbox expansion, including touch player)
  • Timer (anything greater than 20 ticks)

What makes this anticheat "better" compare to other.

You can take a look at a list of "other anti-cheats" here

  • It's free..... and open-source, which is pretty dang good already.
  • Boar is extremly sensitive and can detect EXTREMLY small movement mismatch, designed based off the vanilla movement code making it mathematically impossible to bypass.
  • Boar can accurately detect and cancel any hit beyond 3.0 blocks reach with minimal falses while not affecting legit player but still accurately cancelling cheaters hit.
  • "Perfectly" account for client lag and latency lag without relying on tricks, making it harder to false lagging legits player while still effectively catching cheaters.
  • Accurately check for any timer-based check, even if the cheaters only move 1 ticks faster (1.001x - 1.05x game speed) boar can still catch and detect it, without affecting lagging players.

Note

  • It's not perfect, expect falses, and a lot difference that Bedrock have from Java is un-implementated, so if you do find a bug/false, do report it.
