[PRESS RELEASE \u2013 Zug, Switzerland, August 13th, 2025]<\/strong><\/p>\n

dWallet Labs<\/a>, a core contributor of Ika<\/a>, and a leader in cryptography and decentralized security, today announced REFHE<\/strong> (Ring-Enhanced Fully Homomorphic Encryption), a new encryption scheme that brings encrypted computation closer than ever to how real processors work<\/strong>. REFHE uniquely supports both arithmetic and logical operations<\/strong> on encrypted 64-bit values, enabling software to switch seamlessly between math and logic<\/strong>\u2014just like a modern CPU.<\/p>\n

Why This Matters<\/strong><\/p>\n

Fully Homomorphic Encryption (FHE) allows computation on encrypted data without revealing the underlying information\u2014a capability long considered a \u201choly grail\u201d 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\u2014full of mixed arithmetic and logic\u2014can run encrypted.<\/p>\n

Breaking a Decade of TFHE Dominance<\/strong><\/p>\n

Since 2016, TFHE<\/strong> 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\u2014until now. REFHE delivers:<\/p>\n

100\u00d7 smaller ciphertexts<\/strong>
\n20\u00d7 faster multiplications<\/strong>
\n1,000\u00d7 faster additions<\/strong><\/p>\n

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.<\/p>\n

Implications for 2PC-MPC and the Ika Network<\/strong><\/p>\n

The latest FHE-related research, including REFHE and Threshold FHE, can be integrated into the 2PC-MPC<\/strong> protocol powering the fastest MPC network \u2013 Ika<\/strong><\/a>, 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.<\/p>\n

Building on Recent Threshold FHE Breakthroughs<\/strong><\/p>\n

REFHE follows dWallet Labs\u2019 recent Threshold FHE<\/strong><\/a> 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.<\/p>\n

\u201cThis is more than a speedup,\u201d said Omer Sadika, Co-Founder of Ika and CEO at dWallet Labs. \u201cIt\u2019s 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.\u201d<\/p>\n
