# What is GCHAIN?

GChain is a fork of the Ethereum Network, inheriting its core mechanisms, concepts, tools, and extensive documentation. Built on **EVM compatibility**, GChain ensures faster block times and lower transaction fees.

At the heart of the network are **33 Validator Nodes (BlueNodes)** responsible for consensus. Advanced security measures, including **double-sign detection** and break logic, further strengthen the network’s stability, finality, and resilience.

GChain is a **self-sovereign, decentralized blockchain** that prioritizes security for both validators and the broader ecosystem. Its **EVM compliance** enables seamless integration with Ethereum tools while offering **faster finality** and **ultra-low fees**.

The POA model fosters decentralization and active community participation. As the network’s native currency, **GSYS Coin** powers the ecosystem, serving as both **gas for smart contract execution** and **staking rewards for validators**.
