Fhenix Launches CoFHE for Encrypted Smart Contracts on Ethereum and Arbitrum

Fhenix has announced the launch of its CoFHE (Confidential Fully Homomorphic Encryption) system, now available on the Ethereum and Arbitrum mainnets. This innovative technology allows approved applications to perform computations involving encrypted data, thereby enhancing privacy in blockchain transactions.

Public blockchains often default to transparency, which can be a disadvantage for users who wish to keep sensitive information private. CoFHE addresses this issue by enabling applications to utilize a coprocessor that works with encrypted inputs, protecting sensitive values from being exposed to the entire network. This functionality is particularly relevant for private trading and financial positions.

However, access to CoFHE is currently restricted; Fhenix has implemented an allowlist for contracts that wish to submit workloads, while open testnets remain available for experimentation. The company emphasizes that this development does not automatically render all Ethereum transactions private but serves as an additional tool for developers willing to adopt encrypted computation.

If CoFHE proves effective under real workloads, it could facilitate the integration of confidential finance within established smart contract ecosystems, potentially reducing the need for entirely separate blockchain solutions.
