0G’s Galileo Testnet: Early Adoption Report

When we launched 0G’s v3 testnet (Galileo) in May, the goal wasn’t just better performance: it was to provide further proof that modular blockchain infrastructure can succeed at scaling AI-native applications. After a month of performance, that proof is in the data, as we’ve found that Galileo isn’t just running, but thriving, showing what the future of decentralized AI infrastructure can look like.

What Galileo Set Out to Solve

Most blockchains aren’t built for AI. They’re slow, expensive, monolithic: all qualities that make deploying AI agents onchain difficult, if not nearly impossible. Galileo, the next evolution from our v2 testnet Newton was designed to break that pattern.

As the third major 0G testnet, Galileo introduced:

1. Optimized CometBFT consensus enabling 2,500+ TPS and sub-second finality
2. Fast-track EVM upgrade paths for flexible iteration
3. A development-first environment where AI use cases can actually run
4. Enhanced separation of execution and consensus

Galileo wasn’t a minor tweak; it was a rearchitecture designed to make full-stack, AI-ready infrastructure a reality.

Proof of Performance

In just over a month (May-June), Galileo demonstrated that the architecture works and scales. The key metrics observed as proof of this conclusion thus far are:

• 92 million+ transactions processed
• 6.4 million+ accounts created
• ~2-3 million daily transactions (peaking near 4 million/day)
• 26.65 transactions per second (TPS) sustained in live use with 50+ TPS peaks
• ~1.3 second block time, with headroom to scale up to 2,500 TPS
• 31,000+ daily faucet requests signaling significant active developer interest

It’s essential to note that these figures aren't simulated load or scripted spam; they represent organic growth from a developer community actively engaging with the chain. With block gas usage still at ~10% of capacity, Galileo has an incredible capacity for growth.

Ecosystem in Motion

Of course, performance is only part of the story when it comes to testnets. What’s happening around Galileo is just as exciting as what’s happening on it. 

In the past month, top infrastructure providers like QuickNode, ThirdWeb, and Ankr have rolled out full support for Galileo, making it easier than ever for developers to plug into the network. Explorers like Chainscan and the new Storage Explorer offer real-time transparency across both the EVM and decentralized storage layers, a critical toolset for builders working with AI-native data flows.

Meanwhile, the developer ecosystem is gaining momentum. Early projects are already deploying contracts and experimenting with new AI use cases, taking full advantage of Galileo’s modular stack and low-latency performance. Community growth has been equally strong: during peak periods, the network saw over 400,000 new accounts created daily, eventually settling into a sustained daily average of 100,000-200,000 new accounts. 

What's Next: Mainnet on the Horizon

Galileo is quickly becoming a validation layer for the future of AI-native infrastructure. The performance and growth we’ve seen over the past month confirm that 0G’s architecture can scale in practice, not just in theory. Key design decisions, including modular execution and consensus, as well as rapid EVM upgrade paths, are now live, tested, and proving their value.

Here’s what Galileo has validated so far:

• Modular Design at Scale: Separated execution and consensus layers handled millions of transactions with sustained speed and reliability
• Fast EVM Upgradeability: New features can be shipped without system-wide disruption, giving developers more agility
• Room to Grow: Blocks currently use only 2.5M-4.6M gas (of a 36M limit), leaving significant headroom for 8-10x throughput expansion
• Developer Experimentation: Galileo introduced smart contract-based delegation, allowing validators to offer more flexible staking mechanisms.

Looking ahead, mainnet won’t just bring higher throughput; it will unlock a new class of applications built for a modular, AI-native world. Galileo has proven that the infrastructure is real, the demand is real, and the ecosystem is ready to grow.

Build on Galileo

Here are some ways to get involved:

1. Get test tokens through Galileo’s new faucet.
2. Configure your wallet using the new network configuration details (RPC URL, Chain ID, etc.).
3. Redeploy your contracts on Galileo (sample deployment scripts for Truffle, Hardhat, Foundry here).
4. Track your onchain activity on Galileo’s block explorer.
5. Apply for the Guild on 0G to get access to 0G infra, mentorship, and distribution partners.
