Fhenix, an Ethereum layer-2 platform that desires to carry totally homomorphic encryption (FHE) to good contracts, revealed that it is going to 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 method than a central processing unit. An instance of this within the trade as we speak is zero-knowledge (zk) coprocessors, that are used to scale zk rollup computations off-chain.
FHE coprocessors are related, although their particular focus can be to allow computing over encrypted information with out having to decrypt the knowledge first. FHE coprocessors will be sure that delicate, sophisticated computational duties is not going to be dealt with on Ethereum or a subsequent layer-2 or layer-3, however reasonably by a chosen processor.

“As soon as thought-about inconceivable, FHE coprocessors clear up the problem of analyzing giant information 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 technique to course of encrypted information with out exposing private data, unlocking new use instances on the blockchain.
FHE coprocessors are designed in a technique to obtain inputs from the host chain as a substitute of storing a state themselves, enabling them to be performance-optimized and stay idle till wanted. For effectivity functions, they may depend on fraud proofs as a substitute of zk proofs, which can be settled on the host chain.
FHE coprocessors can 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 can be slashed. Fhenix believes that this removes the need for a fraud-proof interval. Doing so may also eradicate the dispute interval, making affirmation occasions quicker.

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