FHENIX and EIGENLAYER are collaborating to develop a Fully Homomorphic Encryption (FHE) co-processor, with the aim of introducing this technology into smart contracts. The FHE co-processor focuses on performing computations on encrypted data without the need for decryption, thereby improving the efficiency of handling sensitive and complex computational tasks. This co-processor is similar to existing zero-knowledge co-processors, but it focuses on a different technological domain.
