Fhenix, a Layer-2 (L2) network powered by Fully Homomorphic Encryption (FHE), has launched its upgraded nitrogen testnet, as per recent reports shared with Finbold on Wednesday, Nov. 20.
The new upgrade comes with advanced decryption capabilities and other features designed to improve decentralization, security, and the overall experience on the network.
Guy Itzhaki, Chief Executive Officer (CEO) of Fhenix, described nitrogen as an important milestone for the platform:
“The nitrogen testnet is an important step toward 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, gives developers the tools they need to create powerful confidential applications on Ethereum and brings us one step closer to the launch of the Fhenix mainnet.”
Nitrogen Testnet Features
One of the highlights of the Nitrogen testnet upgrade is the Threshold Network, a trust-minimized mechanism that encourages decentralization by handling decryption operations securely, while parallel decryptions address the computational intensity of FHE schemes that enable asynchronous decryption.
To adjust the security and performance of applications, developers on Fhenix also have two security zones at their disposal.
Zone 0 focuses on improving security and minimizing trust requirements.
On the other hand, Zone 1 aims for performance, using a single local key set for decryption.
Additionally, to reduce transaction costs and improve scalability, the Nitrogen upgrade also integrates Celestia, a modular data availability network (DA) that helps modular blockchains develop applications for mass adoption.
Finally, the upgrade introduces native random number generation with the FHE.rand() function.
FHE-powered solutions on Ethereum
By addressing challenges in security, performance, operational costs and the overall user experience, Nitrogen is expected to contribute to Fhenix’s ecosystem of confidentiality-focused applications.
As such, the upgrade marks a significant step forward in the network’s mission to enable secure, scalable, and easy-to-use FHE-powered solutions on Ethereum (ETH).
