Fully Homomorphic Encryption (FHE) Layer 2 Fhenix has announced a major upgrade to its testnet. Nitrogen, the latest iteration, introduces powerful new decryption capabilities and moves Fhenix closer to its mainnet launch.

Nitrogen significantly upgrades the level of decentralization of the Fhenix network with the Threshold Network, the mechanism it uses to handle decryption in a trust-minimized way. 

Another key feature introduced with the Nitrogen upgrade is Parallel Decryptions. Parallel Decryptions mitigate the long and computationally expensive operations FHE schemes entail using asynchronous decryption, providing the fast, seamless experience users have come to expect.

Developers using the Nitrogen testnet will also benefit from Security Zones, providing a flexible approach to dApp security. This will enable applications to be optimized for varying requirements in terms of security and performance. Nitrogen supports two Security Zones. Zone 0 is the default setting that emphasizes security and implies less trust for the user, while Zone 1 prioritizes performance over security using a single local keyset held by the sequencer to process decryption.

Fhenix CEO Guy Itzhaki said: “The Nitrogen testnet is a major step towards providing a permissionless, censorship-resistant platform for confidentiality with FHE. The introduction of the Threshold Network, along with new features such as Parallel Decryptions and Security Zones give developers the tools they need to create powerful confidential applications on Ethereum and bring us one step closer to the Fhenix mainnet launch.”

The latest Fhenix testnet also introduces Celestia for data availability, reducing transaction costs while increasing price stability. Elsewhere, Nitrogen adds the ability to generate random numbers natively and automatically using a simple function called FHE.rand().

Nitrogen represents a significant milestone on the path towards a decentralized platform for onchain confidentiality, delivering major improvements for network security, performance, cost, and UX. The Nitrogen test network achieves significant improvements in decentralization, laying the foundation for a thriving ecosystem of confidentiality-enabled applications on Ethereum.

About Fhenix

Fhenix is the first Ethereum Layer 2 to enable confidential smart contracts using Fully Homomorphic Encryption (FHE), a novel cryptographic scheme that enables computation of encrypted data. Fhenix is EVM-equivalent, enabling developers to write their smart contracts in Solidity using the developer tools they’re familiar with and selectively encrypt them using FHE. Fhenix's goal is to advance Ethereum application development by bringing confidentiality to smart contracts, transactions, and onchain assets for the first time.
