Fhenix, an Ethereum layer-2 platform that desires to deliver absolutely homomorphic encryption (FHE) to good contracts, revealed that will probably be working with EigenLayer to develop FHE coprocessors.
A coprocessor is a further processor designed to carry out specialised duties in an usually extra environment friendly approach than a central processing unit. An instance of this within the business at present is zero-knowledge (zk) coprocessors, that are used to scale zk rollup computations off-chain.
FHE coprocessors are comparable, although their particular focus can be to allow computing over encrypted knowledge with out having to decrypt the knowledge first. FHE coprocessors will be sure that delicate, difficult computational duties won’t be dealt with on Ethereum or a subsequent layer-2 or layer-3, however relatively by a delegated processor.

“As soon as thought of unattainable, FHE coprocessors resolve the problem of analyzing massive knowledge units on Ethereum with out compromising on-chain efficiency,” Fhenix CEO Man Itzhaki stated in a press launch reviewed by Blockworks.
Itzhaki notes that FHE coprocessors will allow a extra environment friendly option to course of encrypted knowledge with out exposing private info, unlocking new use instances on the blockchain.
FHE coprocessors are designed in a option to obtain inputs from the host chain as an alternative of storing a state themselves, enabling them to be performance-optimized and stay idle till wanted. For effectivity functions, they’ll depend on fraud proofs as an alternative of zk proofs, which shall be settled on the host chain.
FHE coprocessors shall be secured by Fhenix’s FHE rollup and EigenLayer’s staking mechanism. EigenLayer allows actively validated providers (AVS) to inherit pooled Ethereum safety.
Through the use of EigenLayer, the FHE coprocessor can assure the financial correctness of the rollup’s execution. If operations are discovered to be malicious, then the stake of those validators shall be slashed. Fhenix believes that this removes the need for a fraud-proof interval. Doing so may even get rid of the dispute interval, making affirmation occasions sooner.

Man Zyskind, the founding father of Fhenix, remarks that FHE coprocessors shall be not solely possible but in addition scalable.
“Confidential computing will develop at scale, and the power to supply instant confirmations wouldn’t be in any other case attainable with out our joint efforts with EigenLayer,” Zyskind stated.
