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.
