Nexus is building a world supercomputer to ensure that everything, from identity to digital content and AI models, is verifiable.
We’ve been getting a lot of questions about what’s coming next. Here are a few upcoming milestones that we’re excited to share:
- Testnet III in Q2 2025 (create your Nexus account to get ready)
- Mainnet I in Q3 2025
- Ongoing, quarterly mainnet releases structured as “seasons”

Testnet III will pressure test the infrastructure of the Nexus Layer 1, ensuring that essential functionality such as everything from account creation, compute contributions, and points distribution is smooth and simple.
Mainnet I will focus on gathering the world’s compute to power a prover network, and will kick off a seasonal release structure. Each three-month season will have its own product advancements and contributor incentives, all building toward an Internet where the blockchain runs on every device, and users themselves power and interact with the world computer to send money, login, interact with apps, socialize, and more.
Contribute compute. Earn rewards onchain. All in one click.

Participating in building the future shouldn’t require specialized knowledge, a custom tech stack, or elite hardware. To get started, all you have to do is create a Nexus account.
The Nexus Layer 1 is a new type of blockchain – lightweight, high performance, and exponentially scalable, it gets more powerful with every node that connects. And it offers an easy, intuitive interface for a new kind of digital service. With a single click, anyone can contribute compute power and get rewarded.
For more advanced users, Nexus also supports a command-line interface (CLI), unlocking seamless integration with global compute supply. Developers can rapidly build and deploy applications that run natively on Nexus Layer 1 and the Nexus zkVM – enabling new forms of verification, identity, onchain activity, and more.
We hope you’ll join us in this journey, beginning with Testnet III in Q2, and then through Mainnet I and the subsequent seasons to follow. If you’re not already part of the network, set up a Nexus account today and get ready for Testnet III.
