Testnet II was a major milestone in the development of the Nexus Layer 1. The Nexus Layer 1 will concentrate all the world’s compute power into a single blockchain.

The goal of Testnet II was to test blockchain integration with the Nexus Network as part of the iterative development of the Nexus Supercomputer. While the process came with its challenges — most notably, keeping up with global demand — the results underscored the potential of a globally distributed, high-performance computational network.

Over a 4.5-day testing period, we saw unprecedented engagement, network scaling, and advancements in the performance of our supercomputer.

Testnet II features

Testnet II was designed for mass adoption. With a brand new user experience, anyone, anywhere was able to:

• Connect and contribute compute instantly on the web app, even from a laptop or mobile device
• Log in with email and automatically get a self-custodial Web3 wallet
• Get NEX Points distributed to their wallet to reward contributions
• View Nexus Network stats for the entire supercomputer
• Check top contributors and track progress on the leaderboard
• Run CLI nodes with an easy setup
• Manage all their nodes in one place
• Transfer NEX Points, deploy apps and tokens on the blockchain
• Interact with partner apps

Building the supercomputer

Here are the results of Testnet II.

COMMUNITY ENGAGEMENT

One of the defining features of the Nexus OS is its ease of access — requiring just one click to connect via a mobile device or laptop, and minimal effort to set up and run a CLI node via a terminal.

We're happy to report these results:

• 2.1 million unique users joined the network during the 4.5-day test period.
• 3.6 million total nodes, more than doubling the node count from the previous testnet.

These results highlight the scale of global participation and the growing adoption of Nexus.

SUPERCOMPUTER PERFORMANCE

Testnet II also marked a breakthrough in distributed computing performance:

• 112 quadrillion FLOPS of compute power contributed across the network.
• 60.4 million verifiable Hz of peak throughput on the Nexus Network.
• More than 30 trillion estimated cycles proved, demonstrating the network’s ability to handle large-scale cryptographic computations.

These results validate the network's infrastructure as a high performance distributed supercomputer capable of executing large-scale computations.

BUILDING ONCHAIN

One of the core objectives of Testnet II was integrating blockchain functionality into the Nexus Network. By the end of the testing period:

• 325,000 new smart contracts were deployed.
• 56,000 new tokens were launched.

The onchain activity, including other Layer 1 stats, remains verifiable via the Nexus Testnet II blockchain explorer, providing a transparent record of network adoption and smart contract deployments.

Continuing development

The Nexus Network has transitioned to devnet mode, meaning the network and its underlying blockchain remain available for builders and developers to continue writing contracts and experimenting with new applications.

Participants from previous testnets can still check their NEX Points balances, while developers can continue utilizing the Nexus blockchain.

Our partners were able to connect with millions of users around the world during this testnet. We want to extend our appreciation to our partners who contributed compute power and infrastructure support during the testnet phase including: Cystic, Finoa Consensus Services, BCW, Gevulot, Code Stream AI, Io Net, RapidNode, Mintair, ZK.Work, EasyNode, Polyhedra, Caldera, Dynamic, Atomic Wallet, Redstone, Galxe, Halliday, and RouteScan.

Big picture

Why are we integrating a blockchain with the Nexus Network and why now? The Nexus Layer 1 is an essential component of the mission to enable the Verifiable Internet, which will redefine digital trust, create a more transparent, secure, and efficient world. The Verifiable Internet enhances security and efficiency for people, developers, businesses, and governments. Verifiability enables new kinds of economic activity and new forms of global commerce.

The possibilities of the Verifiable Internet are endless, with example applications including verifying a statistical model used in breast cancer research, enhancing public trust in media and online information, reducing fraud in financial systems, tamper-proof smart contracts, and more. 

Underlying the Nexus Layer 1 the Nexus zkVM (zero-knowledge virtual machine), enforces transparency and accountability through high-speed and highly parallelized verifiable computation. 

We’ll be sharing more details about the next steps and the 2025 roadmap soon. To stay updated on future testnets and announcements, join the Nexus Discord and follow us on X.
