One of my favorite features of the Baochip-1x is the BIO. It's an I/O coprocessor that is based on the PicoRV32, with custom register extensions to allow direct access to GPIOs from the ISA.

Read more about the BIO at this blog post: https://www.bunniestudios.com/blog/2026/bio-the-bao-i-o-coprocessor/ I go in-depth into the architecture and its trade-offs relative to the PIO, and conclude by working through a couple of coding examples.

Unfaithful Claims: Breaking 6 zkVMs

A zkVM verifier should be faithful to one thing above all else: its public claims. Yet we found six systems where this guarantee breaks. Learn how a subtle ordering bug lets an attacker bypass the cryptography entirely and prove mathematically impossible statements.

I built a microcontroller for high-assurance applications on TSMC 22nm. I call it the "Baochip-1x". Read more about what it is and how it came about at this blog post: https://www.bunniestudios.com/blog/2026/baochip-1x-a-mostly-open-22nm-soc-for-high-assurance-applications/

First Post! Uh, I mean, First CHERIoT Silicon!

We have our first chips back! It is very exciting! Spatial and temporal memory safety, fine-grained compartmentalisation, and also a load of other big chips on a board, so you can play 'Where's ICENI?' on the board picture!
