Overview

Fhenix is building an Ethereum layer-2 network with fully homomorphic encryption so that smart contracts can compute over encrypted data. The design allows confidential balances, sealed-bid auctions and private voting without trusted hardware. The Israeli team works closely with cryptography researchers on making the technique practical on-chain.
