Welcome to the latest edition of the Nexus Changelog — our regular roundup of technical progress across Nexus OS, CLI, Layer 1, and zkVM.
This cycle focused on smarter task orchestration, better user visibility into proving workflows, and backend enhancements that lay the groundwork for scale.
A key protocol update now enables tasks with multiple input sets and proofs, reducing idle time for nodes and improving concurrency across the network.
On the frontend, users can now track proving progress in real time. Under the hood, parts of the task service were rewritten for performance and reliability, including new logic for task assignment based on node reputation.
Meanwhile, work on the zkVM continued with improvements to constraint efficiency and core circuit optimization.
A new progress bar shows proving progress in real time. Visit app.nexus.xyz to try it.
Highlights at a glance
Protocol-level support for multi-input, multi-proof tasks
Backend performance rewrite with key services ported to Rust
A new progress tracking UI for real-time visibility into proving
Weekly leaderboard updates and improved mobile experience
Continued zkVM constraint optimization for speed and completeness
Overall protocol updates
To reduce idle time and improve throughput, we’ve added support for tasks with multiple input sets and proofs. These task structures allow nodes to begin work immediately, even as subsequent inputs are being prepared. As part of this work, the system now provides better visibility into task status and proof submission progress.
Layer 1
The backend continues to evolve with a focus on speed, reliability, and smarter task allocation:
Performance rewrite: Core components of the tasks API have been rewritten in Rust, improving stability and response times under load
Reputation-aware task assignment: Nodes that consistently produce correct proofs and stay online now receive priority access to work — incentivizing high-quality participation
Nexus OS
The OS frontend is now equipped with a new proving progress interface, showing granular updates as tasks are processed and proofs are generated. This upgrade helps users monitor their contributions in real time, improving transparency and trust in the proving workflow.
The leaderboard has also been updated with weekly views and date-based filters, making it easier to track top contributors over time. On mobile, layout and font rendering have been refined for better readability across devices.
Finally, request efficiency has been improved by sending only essential authentication data for most calls — a small but meaningful gain in performance, especially for lower-bandwidth users.
Key changes:
Real-time task progress interface for active proofs
Weekly leaderboard view with date range filtering and faster caching
Mobile design improvements (layout, fonts, responsiveness)
Reduced bandwidth usage via streamlined authentication headers
Nexus CLI
The CLI now supports dynamic version reporting, allowing the server to verify client compatibility in real time. This means users will receive tailored upgrade prompts when their build is out of sync, improving network coherence as the protocol evolves.
zkVM
Work on the zkVM this cycle focused on optimizing the new constraints framework, with changes aimed at improving both proving efficiency and circuit completeness. These updates continue to support the broader effort to modularize and scale the prover architecture.
Why this matters
Together, these updates strengthen every layer of the Nexus stack — from task orchestration to UI clarity to proving speed. As we head toward broader participation and new feature releases, these foundations will support a smoother, more scalable proving experience for all users.
