Fhenix has announced the acquisition of Sunscreen, one of the earliest teams building with fully homomorphic encryption in Web3 . As part of the acquisition, Sunscreen founder Ravital Solomon has joined Fhenix to lead the company’s research efforts, bringing together expertise across TFHE, BFV, encrypted computation, and post-quantum cryptography under one roof. Sunscreen launched publicly in 2022 with an open-source FHE compiler and grants program, later expanding into zero-knowledge tooling, threshold-encrypted systems, developer tooling, and privacy-preserving application architectures. Solomon has been one of the earliest voices helping define what FHE could become for blockchain systems, with work spanning lattice-based post-quantum cryptography, privacy-preserving smart contracts, encrypted computation frameworks, and practical approaches to bringing advanced cryptography into production environments. Acquisition deepens Fhenix’s FHE research stack across Ethereum, Arbitrum, and Base The acquisition comes as Fhenix continues expanding its privacy stack across Ethereum ecosystems through CoFHE, its encrypted computation infrastructure for EVM applications. The company has recently advanced research in threshold FHE decryption, DBFV exact arithmetic, and scalable encrypted computation for real-world blockchain workloads. The combined team deepens Fhenix’s capabilities across BFV, TFHE, threshold cryptography, compiler design, and confidential application architecture. “FHE is entering a new phase,” said Guy Zyskind, Founder of Fhenix. “The conversation is no longer about whether encrypted computation works. It’s about making it scalable, practical, and available across the ecosystems where developers are building today. Sunscreen has been one of the most respected teams pushing this field forward from the very beginning. Bringing Ravital and Sunscreen’s assets into Fhenix allows us to move faster toward our goal of building the quantum-safe privacy layer for Ethereum, Arbitrum, Base, and beyond.” “I started Sunscreen because I believed advanced cryptography should shift from theoretical to usable,” added Ravital Solomon. “What excited me about joining Fhenix is the combination of ambitious research and a clear path to deployment. Fhenix has already built meaningful infrastructure across live blockchain ecosystems, and I’m excited to help lead the next chapter of research as encrypted computation moves closer to mainstream adoption.” The combined research organization will focus on advancing scalable FHE systems, quantum-resistant infrastructure, and the cryptographic foundations required for confidential applications across finance, payments, identity, AI , and other privacy-sensitive onchain use cases.
