Every layer of the Nexus stack is designed to make verifiability feel seamless — whether you’re building, proving, or exploring. This issue of the Changelog reflects key improvements across the board, but the headline is simplicity: the Nexus CLI is now easier than ever to install and more powerful in how it performs. We’ve also deepened verification on Layer 1, boosted interactivity in Nexus OS, and released a new version of our zkVM with stability improvements.

CLI: Precompiled builds and parallel proving

One of the biggest pain points for developers has now been solved. The Nexus CLI no longer requires compiling from source—just download a precompiled binary and start using it instantly.

You can install the latest CLI release with a single command:

curl https://cli.nexus.xyz/ | sh

Precompiled builds are now available for:

• macOS (M1/M2/M3, Intel)
• Windows
• Linux (x86, ARM64)

In addition, the CLI now supports parallel proving. With the new --max-threads flag, users can unlock multicore performance for faster local proving and increased rewards.

Layer 1: Full proof verification across the network

Previously, Nexus Layer 1 only verified a subset of submitted proofs. With this release, every proof — whether generated via the CLI or the web interface—is now being verified by the network. This ensures greater trust, integrity, and auditability.

Behind the scenes, verification is powered by instances of the Nexus zkVM running on dedicated cloud infrastructure. It’s a foundational upgrade that strengthens the network’s guarantees without compromising performance.

Nexus OS: Smoother UX, faster loads

Nexus OS continues to evolve as the fastest way to interact with verifiable applications. Recent frontend improvements include:

• Web workers now handle intensive proving tasks in the background, keeping the interface responsive and snappy even during complex operations.
• The interactive globe map homepage has migrated to a self-hosted backend. This improves loading speed, unlocks deeper customization, and enables richer animations.

These changes make the OS feel lighter and more immediate—bringing a desktop-like experience to the browser.

zkVM: v0.3.4 released

The Nexus zkVM has been updated to v0.3.4. This release includes a set of minor patches and stability fixes that improve reliability for proof generation and verification. It’s part of our continuous commitment to refining the foundation of verifiable compute.

Looking ahead

We are getting closer to our upcoming Testnet III, which will include new functionality across the Nexus OS.
