OpenTitan Open-Source Root-of-Trust Chip Ships in Production Hardware

Canopy Hardware

Google announced on March 5, 2026 that OpenTitan — the first open-source silicon root-of-trust chip — has begun shipping in production hardware, marking a significant milestone for transparent, verifiable security in compute infrastructure. OpenTitan is designed to replace proprietary secure-boot and attestation chips with a fully auditable, open design that any manufacturer can inspect and build upon. The project, hosted by lowRISC under Google's backing, has now passed from research prototype to real-world deployment in commercial devices.

Key Takeaways

  • OpenTitan is the first open-source root-of-trust (RoT) silicon chip to reach production; it uses a RISC-V core and open RTL verified via formal methods
  • Replaces closed proprietary TPM/secure-boot chips with a fully auditable design — supply-chain transparency and firmware provenance are primary use cases
  • Announced via Google Open Source Blog (March 2026); hosted by lowRISC under an open-source governance model with multiple industry contributors
