[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
