## Summary

A curated list of Fully Homomorphic Encryption (FHE) and blockchain resources centers on fhEVM, a Zama-developed technology that enables confidential smart contracts on the Ethereum Virtual Machine. According to the list, fhEVM keeps transaction data and state encrypted, allows encrypted state to coexist with public state without affecting existing dapps, and has validators perform computations on encrypted data locally. It also catalogs projects such as Zama, Fhenix, Inco, Octra and Shibarium, along with libraries, documentation, communities and educational materials.

What is fhEVM?

fhEVM is a technology that enables confidential smart contracts on the Ethereum Virtual Machine (EVM) using Fully Homomorphic Encryption (FHE). It is developed by Zama, and you can learn more about it in their fhEVM GitHub repository.

Key Features of fhEVM:

End-to-end encryption of transactions and state, ensuring data included in transactions is encrypted and never visible to anyone.

Composability and data availability on-chain, with states updated while remaining encrypted at all times.

No impact on existing dapps and state, allowing encrypted state to co-exist alongside the public one without affecting existing dapps.

Mechanism behind fhEVM:

Everything is encrypted under a single global FHE public key.

The global secret key is generated using a threshold protocol (parts of the secret key are distributed among validators).

The inputs are encrypted using the FHE public key.

Computations on encrypted data are done locally by validators.

Values can be decrypted by validators using the threshold protocol.

Values can also be re-encrypted (without decryption) under another public key (let’s denote it “public key a”) using a threshold protocol. Re-encrypted values can be decrypted by the public key owner.
