Xous 0.10.0: Security-Focused Open-Source OS Adds Baochip 1X Support on 22nm Custom Silicon

Canopy Hardware

Xous, the security-focused open-source microkernel operating system designed for the Precursor open-hardware security device, released version 0.10.0 with support for the new Baochip 1X — custom 22nm silicon built to run Xous directly in hardware, rather than relying on an FPGA. The Precursor platform, manufactured by SiFive co-founder Andrew 'bunnie' Huang's company Sutajio Kosagi, aims to provide a fully auditable, open-source hardware and software stack for security-sensitive applications, with the move to custom silicon representing a major transition from the prototype FPGA stage. The release accumulated 54 HN points, reflecting niche but deep interest from hardware security researchers and developers building high-assurance systems.

Key Takeaways

  • Xous 0.10.0 introduces Baochip 1X support — custom 22nm ASIC purpose-built to run Xous; replaces FPGA-based Precursor prototype with production silicon for the Precursor open-hardware security platform
  • Precursor device is designed for fully auditable open-source hardware/software security applications (e.g., secure key storage, communications) — manufactured by Sutajio Kosagi (bunnie Huang)
  • 54 HN points and 9 comments on March 2, 2026; significant milestone for the open-source hardware security space — moves Precursor from FPGA prototype to production-ready custom silicon
