dWallet Labs’ Ika Core Team Unveils REFHE: The World’s First Fully Functional FHE CPU-Like Protocol

Breaking the encryption barrier—dWallet Labs just dropped a cryptographic bombshell.

REFHE isn't just another FHE scheme—it's the first to mimic a real CPU, opening floodgates for private computation.

How it works:

- Processes encrypted data without decryption (finally)

- Executes complex operations like a traditional processor

- Could make today's 'secure' cloud setups look like tin cans and string

Wall Street analysts are already calling it 'GDPR's worst nightmare' while simultaneously pitching REFHE-backed hedge funds. Because nothing sells like fear wrapped in financialization.

This changes everything—if it works outside a test environment.

dWallet Labs, a Core contributor of Ika, and a leader in cryptography and decentralized security, today announced(Ring-Enhanced Fully Homomorphic Encryption), a new encryption scheme that brings. REFHE uniquely supportson encrypted 64-bit values, enabling software to—just like a modern CPU.

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.

Since 2016,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

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.

The latest FHE-related research, including REFHE and Threshold FHE, can be integrated into theprotocol powering the fastest MPC network –, 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.

REFHE follows dWallet Labs’ recentresearch, 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.

“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.”

Ika is the fastest parallel MPC network, offering sub-second latency, unprecedented scale and decentralization, and zero-trust security.
