- In May 2025, Zama, a pioneer in Fully Homomorphic Encryption (FHE), introduced the HPU on FPGA, the first-ever open-source hardware accelerator designed specifically for FHE workloads. Built for the AMD Alveo V80 FPGA, this Homomorphic Processing Unit (HPU) executes encrypted computations directly on hardware, significantly reducing the computational burden associated with FHE. The release includes SystemVerilog RTL, firmware, simulation flows, and bitstream generation tools, all freely available to developers. This breakthrough marks a major step toward making FHE scalable and practical for real-world applications such as privacy-preserving AI and encrypted cloud computing
- In April 2025, Zama launched its Threshold Key Management System (TKMS) to strengthen the security and scalability of Fully Homomorphic Encryption (FHE) deployments. TKMS uses threshold cryptography to split decryption keys across multiple parties, ensuring no single entity holds the full key. Built on a secure Multi-Party Computation (MPC) protocol, it supports key generation, resharing, and threshold decryption for FHE schemes such as TFHE, BGV, and BFV. This system is optimized for enterprise use, offering resilience, auditability, and compatibility with decentralized infrastructures—making FHE more practical for real-world applications
- In February 2025, Zama released TFHE-rs v1.0, marking a major milestone for its Fully Homomorphic Encryption (FHE) library. This first stable version introduces a refined high-level API for the x86 CPU backend, ensuring backward compatibility and reducing the probability of computational errors to less than 2⁻¹²⁸—a level aligned with modern cryptographic standards. The update also includes an official TFHE-rs handbook, optimized cryptographic parameters, and support for distributed protocols. With this release, TFHE-rs becomes a production-ready, reliable tool for developers and researchers working on privacy-preserving applications
- In December 2024, Zama launched the fhEVM Coprocessor, a groundbreaking solution that enables the execution of Fully Homomorphic Encryption (FHE) smart contracts on Ethereum, Base, and other EVM-compatible chains. This coprocessor allows developers to build confidential decentralized applications (dApps) without modifying the underlying blockchain protocols. It supports encrypted transaction inputs and on-chain state, while maintaining composability, meaning smart contracts can interact seamlessly—even when operating on encrypted data
- In November 2024, J.P. Morgan’s Kinexys (formerly Onyx) released a proof-of-concept (PoC) in collaboration with Zama, showcasing the use of Fully Homomorphic Encryption (FHE) for privacy-preserving financial transactions. Part of Project EPIC, the PoC explored encrypted fund subscriptions, blind secondary market trading, atomic settlement, and confidential KYC/AML compliance using Zama’s fhEVM Coprocessor. These innovations allow institutions to process sensitive data—such as bid amounts and investor identities—without ever decrypting it, ensuring both privacy and regulatory compliance
