Chain Reaction is a company focused on developing application-specific integrated circuits (ASICs) and fully homomorphic encryption (FHE) processors. Its core product, the 3PU™, is a processor designed for encrypted computation, enabling direct operations on data while it remains encrypted. This supports privacy-preserving AI and cloud workloads. The technology addresses the pain point of traditional computing that requires decryption before processing, and is applicable to industries with high data security requirements such as finance, healthcare, and defense.
