Zug, Switzerland, August 13th, 2025/Chainwire/--dWallet Labs, a core contributor of Ika, and a leader in cryptography and decentralized security, today announced REFHE (Ring-Enhanced Fully Homomorphic Encryption), a new encryption scheme that brings encrypted computation closer than ever to how real processors work. dWallet Labs dWallet Labs Ika Ika 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 DominancAe 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× smaller ciphertexts
20× faster multiplications
1,000× faster additions 100× smaller ciphertexts 20× faster multiplications 1,000× 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 2PC-MPC and the Ika Network The latest FHE-related research, including REFHE and Threshold FHE, can be integrated into the 2PC-MPC protocol powering the fastest MPC network - Ika, coordinated on Sui. With these breakthroughs, 2PC-MPC could directly execute its Zero-Trust signing with FHE, reducing communication rounds and boosting latency, throughput, and security. Ika Ika Building on Recent Threshold FHE Breakthroughs REFHE follows dWallet Labs’ 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. Threshold FHE Threshold FHE "This is more than a speedup," said Omer Sadika, Co-Founder of Ika and CEO at dWallet Labs. "It’s about finally aligning encrypted computation with the way real software and CPUs work. That opens up a new class of secure, privacy-preserving applications that were simply not practical before."
