DWallet Labs announces REFHE (Ring-Enhanced Fully Homomorphic Encryption) ReFHE is a new encryption scheme that brings encrypted computation closer than ever to how real processors work. It uniquely supports both arithmetic and logical operations on encrypted 64-bit values, enabling software to switch seamlessly between math and logic.

This audio is presented by Hacker Noon, where anyone can learn anything about any technology. ICA core contributor D-Wallet Labs reveals REFHE, first FHE scheme that works like a real CPU, by Chainwire. Zug, Switzerland, August 13th, 2025, Chainwire, D Wallet Labs, a core contributor of ICA, and a leader in cryptography and decentralized security, today announced Reef, Ring enhanced fully homomorphic encryption. A new encryption scheme that brings encrypted computation closer than ever to how real processors work. REFHE uniquely supports both arithmetic and logical operations on encrypted 64-bit values, enabling software to switch seamlessly between math and logic, just like a modern CPU.

Why this matters fully homomorphic encryption, FHE, allows computation on encrypted data without revealing the underlying information, a capability long considered a holy grail of cryptography. but existing schemes typically force a trade-off, choose between efficient arithmetic or efficient logic. REFHE removes that barrier, creating a unified approach where real-world software, full of mixed arithmetic and logic, can run encrypted. Breaking a decade of TFHE dominance since 2016, TFHE has been one of the most widely used FHE schemes, especially in the context of blockchain use cases, and is leveraged by companies such as Zama. For nearly a decade, No scheme had meaningfully surpassed its performance and latency, until now.

REFHE delivers 100 times smaller ciphertexts, 20 times faster multiplications, 1,000 times faster additions. These gains, alongside being optimized for both arithmetic and logical operations, make it the first FHE scheme capable of operating as a practical, CPU-like encrypted execution engine. Implications for 2PCMPC and the IKA network the latest FAA, related research, including REFHE and Threshold FHE, can be integrated into the 2PC-MPC protocol powering the fastest MPC network, ICA, coordinated on sway. With these breakthroughs, 2PCMPC could directly execute its zero-trust signing with FHE, reducing communication rounds and boosting latency, throughput, and security. Building on recent Threshold FHEBRE-A-K-T-H-R-U-G-H-R-E follows D-Wallet-Lat-Lab's

recent threshold FHE research, which enables scalable, efficient, secure multi-party decryption. Together, these advances form the basis for encrypted systems that are both high-performance and capable of real-world program logic. Greater than... This is more than a speed-up, said Omar Siddiqua, co-founder of Ica and CEO at Greater Than D-Wallet Labs. It's about finally aligning encrypted computation with the way greater than real software and CPUs work.

That opens up a new class of secure. greater than privacy-preserving applications that were simply not practical before. About ICICA is the fastest parallel MPC network, offering sub-second latency, unprecedented scale and decentralization, and zero-trust security. As the premier choice for interoperability, decentralized custody, and chain abstraction, Ica is set to revolutionize digital asset security and multi-chain defy.
