As AI agents grow more capable, they’re starting to do more than just analyze data or generate text — they’re beginning to act in the world. Ordering groceries, booking rides, executing trades. But with this new agency comes a challenge: How do we build infrastructure that can keep up?
AI agents don’t sleep, and they don’t wait. They operate at machine speed, generating transactions at scales far beyond what today’s blockchains can handle. To support this future — a world of billions of autonomous agents transacting in real time — we need a fundamental shift in architecture.

Blockchain designed for AI
Nexus is building the first blockchain designed from the ground up for the AI era.
At its core, Nexus is a world supercomputer — a distributed system that becomes faster as more people connect. Every node runs a zero-knowledge virtual machine (zkVM), working in concert to generate a single, compact cryptographic artifact: the Universal Proof.
This proof captures the full state and history of the chain. It’s small enough to verify on any device, enabling a radical redesign of how blockchains work.
Three layers of scale
We are building a blockchain system that will separate execution, consensus, and storage into independent supercomputer systems — each one scaling on its own path:
- Execution Layer: Aggregates global compute by running zkVMs across billions of devices. It scales vertically as zkVMs advance and horizontally as more nodes join. Anyone can contribute compute with one click via Nexus OS — even from a phone.
- Consensus Layer: Designed to scale the L1’s economic security. As capital flows in, staking expands across nested rings of validators, all working to agree on the Universal Proof.
- Storage Layer: Will scale blockchain storage capacity using data availability sampling and hyperdimensional encodings. Where storing a 10MB image on Ethereum might cost $1 million, Nexus aims to drop that to mere cents — all with massive resilience.
Built for the future
Nexus is built for a world where AI agents coordinate contracts, payments, and services at massive scale. Zero-knowledge cryptography provides the trust. A globally distributed compute network provides the power. And a universal proof connects it all.
The result is a blockchain that matches the speed, scale, and intelligence of the systems it’s designed to serve.
Join the network
The future is being built now — at the intersection of AI, blockchain, and zero knowledge.
To help build it, we’re inviting developers, researchers, and contributors to join the Nexus testnet. Spin up a node. Run compute. Help shape the foundation of the next Internet.
