0G Chain: The Fastest Modular AI Chain

The Problem with AI on Blockchain​

Try running an AI model on Ethereum today:

  • Cost: $1M+ in gas fees for a simple model
  • Speed: 15 transactions per second (AI needs thousands)
  • Data: Can't handle AI's massive data requirements

What is 0G Chain?​

0G Chain is a blockchain built specifically for AI applications. Think of it as Ethereum, but optimized for AI workloads with significantly higher throughput.

How 0G Chain Works​

Modular Architecture​

0G Chain features an advanced modular design that distinctly separates consensus from execution. This separation into independent, yet interconnected, layers is a cornerstone of 0G Chain's architecture, delivering enhanced flexibility, scalability, and a faster pace of innovation.

Architecture Overview:

  • Consensus Layer: Dedicated to achieving network agreement. It manages validator coordination, block production, and ensures the overall security and finality of the chain.
  • Execution Layer: Focused on state management. It handles smart contract execution, processes transactions, and maintains compatibility with the EVM (Ethereum Virtual Machine).

Key Technical Advantages:

  • Independent Upgradability: The execution layer can rapidly incorporate new EVM features (such as EIP-4844, account abstraction, or novel opcodes) without requiring changes to the underlying consensus mechanism.
  • Focused Optimization: Conversely, the consensus layer can be upgraded with critical performance or security enhancements without impacting the EVM or ongoing execution processes.
  • Accelerated Development: This decoupling allows for parallel development and faster iteration cycles for both layers, leading to quicker adoption of new technologies and improvements in both performance and features.

This design makes 0G Chain flexible and fast. When new blockchain features come out, we can add them quickly without breaking anything. This keeps 0G optimized for AI while staying up-to-date with the latest technology.

Optimized Consensus​

0G Chain employs a highly optimized version of CometBFT (formerly Tendermint) as its consensus mechanism, with meticulously tuned parameters that achieve maximum performance while maintaining security. The system features carefully calibrated block production intervals and timeout configurations that work together to deliver high throughput, ensure network stability, and enable faster consensus rounds—all without compromising the fundamental safety guarantees.

These optimizations enable 0G Chain to achieve maximum performance:

  • 2,500+ TPS: Current throughput significantly exceeds traditional blockchain networks
  • Sub-second Finality: Near-instant transaction confirmation for AI applications
  • Consistent Performance: Maintains high throughput even under heavy network load

Scaling Roadmap​

  • DAG-Based Consensus: Transitioning to Directed Acyclic Graph (DAG) based consensus for exponentially higher efficiency
    • Parallel transaction processing capabilities
    • Elimination of sequential block limitations
  • Shared Security Model: Implementing shared staking mechanisms to enhance network security
    • Validators can secure multiple services simultaneously
    • Increased capital efficiency for stakers

Technical Deep Dive​

How does 0G achieve high throughput?

Currently achieves 2,500 TPS through:

  1. Optimized CometBFT: Highly efficient consensus based on Tendermint
  2. Efficient block production: Tuned for AI-scale data processing
  3. Fast finality: Sub-second transaction confirmation

Future scaling will add:

  • Multiple parallel consensus networks
  • Dynamic capacity expansion
  • Automatic load balancing
How does the validator system work?

Staking & Consensus:

  • Validators stake 0G tokens to participate
  • CometBFT ensures Byzantine fault tolerance

Rewards:

  • Block production rewards
  • Transaction fee collection
  • Staking yields proportional to stake size

Node Selection:

  • VRF (Verifiable Random Function) for fair validator selection
  • Prevents collusion and ensures decentralization
What makes 0G different from other fast chains?

Unlike general-purpose "fast" blockchains:

  • AI-First Design: Data structures optimized for AI workloads
  • Modular Architecture: Upgrade components independently
  • EVM + More: Start with Ethereum compatibility, expand to other VMs
  • Purpose-Built: Not retrofitted - designed from scratch for AI
0G Chain Architecture

0G Chain's modular architecture enables seamless integration with storage, compute, and DA layers

Validator Participation​

Validators earn rewards through:

  • Block rewards: For producing valid blocks
  • Transaction fees: From network usage
  • Staking rewards: Based on stake size and uptime

Frequently Asked Questions​

Is 0G Chain truly decentralized?

Yes! 0G Chain operates with a permissionless, globally distributed validator set using proof-of-stake consensus. No single entity controls the network.

Do I need to rewrite my Ethereum dApp?

No! Full EVM compatibility means your Solidity code deploys without changes. The only differences you'll notice are speed and cost improvements.

Why is it faster than Ethereum?

0G Chain is purpose-built for AI workloads, while Ethereum is general-purpose. We achieve speed through:

  • Optimized consensus mechanism (CometBFT)
  • AI-specific data structures
  • Focused use case optimization
