Vulcan
Vulcan Anticheat is a multi-version anti-cheat system for Minecraft servers, written in Java and supporting versions 1.8 through 1.21. With over 10,000 downloads and peak usage of 36,000 players checked per day, it stands as one of the most respected anti-cheats in the Minecraft plugin ecosystem. I contributed to Vulcan 2.0, a complete rewrite of the original plugin, delivering a new codebase and core detections based on a significantly improved version of my prior project, Medusa. I maintained this new foundation for four months, supporting its evolution into a trusted tool for both casual and competitive servers.

A second chance
Vulcan 1.0 had promise, but struggled to deliver in practice. High false positives and inconsistent performance made it hard to recommend. Vulcan 2.0 was that second chance, an opportunity to rebuild everything right. By contributing a clean architecture, robust detection logic, and attention to performance, I helped turn a struggling product into a high-performance tool ready for scale.
A clean reboot
Rather than patch over the old flaws, Vulcan 2.0 started fresh, with new systems, new priorities, and a new commitment to performance. The transition from a buggy legacy version to a stable, multi-version solution was a full rewrite, not a refactor. My code formed the early backbone of that transformation, giving future contributors a reliable base to build on.
A future of stability
Even after my contributions ended, Vulcan 2.0 kept growing. Its lightweight footprint, thanks in part to design principles inherited from Medusa, meant it could scale effortlessly to thousands of players per day without dragging down server performance. The fact that it’s now one of the most downloaded and top-rated anticheats on SpigotMC speaks to the long-term value of building things right the first time.
