Google has partnered with several tech companies to develop and build OpenTitan, a new, collaborative open-source secure chip design project.

The aim of the new coalition is to build trustworthy chip designs for use in datacenters, storage, and computer peripherals, which are both open and transparent, allowing anyone to inspect the hardware for security vulnerabilities and backdoors.
