Welcome back to the Nexus Changelog — our regular roundup of product updates spanning the Nexus Layer 1, OS, CLI, and zkVM. This edition highlights improvements to user visibility, backend scalability, and proving efficiency, with a particular focus on node usability and core performance enhancements.

Summary of recent changes

• Nexus OS launched a new global activity map and responsive layout updates
• CLI saw improvements in onboarding and backend performance
• Layer 1 introduced concurrent proving and proof verification systems
• zkVM gained a Keccak precompile and a major memory model upgrade, enabling faster proving and better traceability

Nexus OS: A new view of global scale

The latest release of Nexus OS brings new visibility and usability features to the forefront. A dynamic global activity map now visualizes node presence and activity in real time, complete with user location display. 

Alongside the map, the interface has been refreshed across mobile, tablet, and desktop — making it easier to navigate wallets, stats, and proving tools. These updates are paired with backend improvements that simplify node onboarding and enhance reliability during registration, setting the stage for a more accessible and resilient proving experience.

Interactive map
Added an interactive global map view with a “locate me” feature to visualize real-time network activity

Stat fidelity
Refreshed homepage layout across mobile, tablet, and desktop for easier access to proving stats, wallet info, and entry points

CLI nodes
We made updates designed to streamline onboarding

• Simplified node addition via CLI through the OS interface
• Improved backend responsiveness during node registration, reducing failure modes and timeouts

Layer 1: Proof verification

We introduced a proof verification service to independently validate submitted proofs and strengthen the trust model for proving rewards.

Backend updates
The backend now supports concurrent proving tasks from up to 100 CLI sessions or browser tabs per node.

zkVM

Two major internal updates have advanced the performance and reliability of the Nexus zkVM. The first is the integration of a Keccak round function as a precompile, delivering a dramatic speedup in computing full Keccak hashes. The second is a substantial upgrade to the emulator’s memory management system, which improves the efficiency of guest memory usage, enhances traceability, and unlocks faster proving. Together, these changes strengthen the core of the zkVM as we continue scaling its capabilities.

Additional updates

• Refactored internal tooling and updated dependencies for better compatibility and future expansion
• Introduced minor prover integration enhancements to reduce proving time and improve runtime stability

Looking ahead

These changes lay the foundation for the upcoming Testnet III, which will include new tools to observe, manage, and participate in the global Nexus network. Stay tuned for further updates as we continue pushing toward a more Verifiable Internet.
