Chain Reaction

Chain Reaction is a semiconductor company focused on purpose-built processors for encrypted computing. Its core business centers on developing hardware that accelerates Fully Homomorphic Encryption (FHE), enabling computations to run directly on encrypted data without decryption. The company's flagship product, the 3PU™ processor, is designed for AI and cloud workloads, offering high-performance encrypted computation at scale.

Key pain points addressed include the traditional high overhead of FHE, which has limited its practical use. By creating dedicated hardware, Chain Reaction reduces the computational cost and latency of encrypted processing, making privacy-preserving data analytics, secure cloud computing, and confidential AI feasible for industries like finance, healthcare, and defense.

In the past six months (February to August 2026), Chain Reaction published a research paper on distributed generation of uniformly sampled polynomials for FHE accelerators, improving the efficiency of polynomial sampling in encrypted computation. The company also highlighted the importance of software tools in making FHE practical, signaling ongoing development in its ecosystem. No major negative events were reported during this period.
