FerrumC
A reimplementation of the minecraft server in rust
FerrumC is a re-implementation of a server for the game Minecraft (version 1.21.8) built from scratch in Rust, designed to offer significantly improved performance and memory efficiency compared to vanilla server implementations. By using Rust’s concurrency and safety guarantees, FerrumC runs fully multithreaded, allowing it to utilize all available CPU cores — which helps deliver smoother, low-latency, high-throughput multiplayer experiences. The project aims both at providing a fast, lean server for typical use (friends or small communities) and offering a foundation that could support large-scale servers, mod/plugin systems, and custom server configurations. FerrumC supports importing existing Minecraft worlds, making it easy for users to migrate from standard servers without losing progress. Its networking, world encoding (chunks, NBT, Anvil format), and entity systems are custom-built with efficiency in mind, which results in fast world loading, minimal I/O lag.
