0G Testnet Guide

The 0G Newton testnet is live, offering developers, validators, and researchers a hands-on opportunity to build, test, and refine AI-powered blockchain applications. 

As the first decentralized AI layer (AIL), 0G’s modular, infinitely scalable layer 1  is built to support the next generation of AI-native applications. Designed for AI execution at scale, 0G unifies decentralized storage, compute, and data availability (DA) to support the next generation of AI-native applications. 

And with Newton v2, 0G introduces enhanced modularity, deeper builder interactions, and a framework for decentralized AI that prioritizes transparency, ownership, and scalability.

This guide covers:

1. An overview of 0G

2. Newton Testnet details

3. Getting started with Newton Testnet

For the full testnet guide, see our developer documentation.

What is 0G?

0G (Zero Gravity) is the first decentralized AI operating system, combining compute, data availability, and storage into a single, verifiable blockchain platform. 

Unlike traditional AI infrastructure, where models, training data, and compute power are siloed under centralized control, 0G encompasses the entire onchain AI tech stack, ensuring AI remains trustless, transparent, and accessible to builders and users worldwide. In short, the most exciting innovations in AI will be built on decentralized infrastructure, and 0G provides the complete toolkit for making this vision a reality!

0G’s Newton Testnet

0G’s latest testnet deployment, Newton v2, brings major performance upgrades, with optimizations for AI inference, decentralized storage at $10 per TB, and integrations with leading rollup frameworks.

The testnet consists of four key infrastructure layers:

1. 0G Chain (AI-Optimized L1)

• Now featuring a custom consensus model designed for AI workloads

• Enhanced EVM compatibility for seamless smart contract deployment

• New shared staking model improves validator incentives

2. 0G Compute Network (Decentralized AI Execution)

• Supports trustless AI inference through TEEs (Trusted Execution Environments)

• Expanded model support, including Llama-3.3-70B-Instruct and DeepSeek-R1-70B.

• Now provides real-time rewards for compute providers

3. 0G Storage Network (AI-Optimized Storage)

• Now offers decentralized storage at $10-11 per TB

• Utilizes Proof of Random Access (PoRA) for verifiable AI data storage

• Faster retrieval speeds compared to Filecoin & Arweave

4. 0G Data Availability (DA) (Scalable Onchain Data Layer)

• Fully integrated with OP Stack, Arbitrum Nitro, and rollup solutions

• Features advanced erasure coding & multi-consensus security

Testnet Configuration Details

0G’s current testnet configuration provides everything you need to start exploring and building:

Newton Testnet Explorer

To help builders and node operators monitor and interact with 0G's testnet in real time, 0G has launched two testnet explorers.

• Chain Explorer: chainscan-newton.0g.ai

• Storage Explorer: storagescan-newton.0g.ai

• Contract addresses can be accessed via 0G’s developer docs.

These explorers provide full visibility into Newton v2’s transactions, validator performance, and storage node activity, making it easier for users to track their deployments, inspect live network activity, and verify onchain AI computations.

How to Participate in Newton Testnet

With Newton v2 testnet, developers can start leveraging 0G's infrastructure for groundbreaking applications today. This includes the ability to:

• Deploy smart contracts on 0G's EVM-compatible chain

• Build decentralized AI applications with 0G Compute Network

• Store and retrieve massive AI datasets with 0G Storage

• Integrate with rollup solutions through 0G DA

For node operators, there are three main ways to interact with the Newton v2 testnet:

1. Run a Validator Node 

Validators secure the 0G network by validating transactions and proposing new blocks through a Proof-of-Stake mechanism. With top-tier validators earning rewards, this is your chance to help secure the foundation of decentralized AI.

Hardware Requirements:

• Memory: 64 GB RAM

• CPU: 8 cores

• Disk: 1 TB NVME SSD (4 TB for Testnet)

• Bandwidth: 100 MBps

2. Run a Storage Node

Storage nodes maintain 0G's decentralized storage layer, storing and serving data while ensuring availability and reliability. Contribute storage resources and earn rewards for your participation.

Hardware Requirements: 

• Memory: 16 GB RAM

• CPU: 4 cores

• Disk: 500GB/1TB NVME SSD

• Bandwidth: 500 MBps

3. Run a DA Node

DA nodes verify blob data, sign it, and store it for future farming and rewards. With 0G's unique data availability approach, you can participate in securing data for Layer 2 solutions and rollups.

Hardware Requirements: 

• Memory: 16 GB RAM

• CPU: 8 cores

• Disk: 1 TB NVME SSD

• Bandwidth: 100 MBps

How you choose to engage with Newton v2 comes down to your hardware capabilities and vision for how you’d like to help build the future of decentralized AI. Each of the above interactions gives you a chance to familiarize with 0G’s maturing ecosystem as we advance towards mainnet deployment together.
