Testnet III marks the next major milestone in the development of the Nexus Layer 1 — the L1 for the AI era.
Where Testnet II validated massive participation and early blockchain integration, Testnet III was about pushing usability even further.
Over the past week of testing global participants came together to prove that the supercomputer of the future will be built by anyone, anywhere — powered by open infrastructure and verifiable compute.
Testnet III: Designed for real-world scale
Building on the momentum of Testnet II, we upgraded the Nexus OS for an even more seamless user experience. This testnet introduced new orchestration layers, backend performance upgrades, and improved visibility across the network.
With just a few clicks, users can:
Connect and contribute compute directly via browser or CLI
Automatically generate a self-custodial Web3 wallet
Earn and track NEX Points for compute contributions
Testnet III saw massive engagement — a testament to the accessibility of Nexus and the growing global interest in verifiable infrastructure.
2.6 million unique users with Nexus accounts
823,200 peak nodes connected to the world supercomputer at the same time
Participants spanned 190 countries, demonstrating global reach, top regions include: United States, India, Vietnam, Hong Kong SAR and Mainland China, Indonesia, Nigeria, Singapore, Japan, Thailand, Pakistan
These numbers show growth and momentum — the Nexus world computer is fast becoming one of the most active compute networks in the world.

The path forward
Testnet III brings us one step closer to a new era: the Verifiable Internet.
By combining a global compute network with a high-speed, proof-generating blockchain, Nexus is enabling a new class of applications — from fraud-proof AI and transparent media to secure scientific research and provable finance.
The vision remains unchanged: concentrate the world’s compute power into a single, verifiable system — and make it accessible to everyone.
