Krypton is a mod that attempts to optimize the Minecraft networking stack. It derives from work done in the Velocity, VelocityNT Recast and Paper projects.
Krypton derives itself from Ancient Greek kryptos, which means "the hidden one". This makes it evident most of the benefit from Krypton is "hidden" but is noticeable by a server administrator.

Feature
- More related minor optimizations
- Implemented RecastLib
- Support NeoForge/Forge
What is RecastLib
RecastLib is a native library I wrote in Rust that is compatible with Velocity Native JNI Bind.
It aims to make up for some of the shortcomings of Velocity Native compatibility, thereby making the performance advantages of KryptonFNP more comprehensive.
In KryptonFNP for Fabric, I’m also testing the stability of the FFM APIs available in Java 22, which, according to benchmarks, should provide more performance gains (ultimately Fabric only. Forge/NeoForge won’t be able to run them).
Their benefits are obvious that both Server and Client can benefit, and that most popular PCs can run these native libraries due to the replacement compatibility.
Compatibility
| System & Arch | RecastLib | Velocity Native |
|---|---|---|
| Windows x64 | Yes | No |
| Windows arm64 | Yes | No |
| Linux x64 | Yes | Yes |
| Linux arm64 | No | Yes |
| MacOS arm64 (Apple Silicon) | No | Yes |
Currently, there are no plans to provide compatibility for Android, 32-bit architecture operating systems, or other architectures.
Please do not open any related issues or complain to me, even if you do, I can't help.
