# Validators

## **Consensus and Validator Role in GChain**

Since blockchain networks rely on a consensus mechanism, it is essential to establish a robust protocol for how new blocks are committed. Validators play a crucial role in maintaining the security and integrity of the blockchain. These nodes process transactions, determine block order, and sign blocks with cryptographic signatures to confirm transactions.

### **Validators and Their Role**

Validators are responsible for authenticating transactions and securing the blockchain by verifying and adding new blocks.

* **Validator Selection:** Validators are chosen based on their stake and network participation. Those with a longer commitment and higher stake have a greater chance of being selected.
* **Block Confirmation:** Once a validator processes a block, other validators must verify its accuracy before it is confirmed on the blockchain.
* **Earning Rewards:** Validators earn rewards through transaction fees and commissions, distributed in proportion to their contributions.

## **Reward Distribution**

Block rewards, derived from gas fees, are distributed among:

1. The validator that created the block.
2. The network for sustainability and development.

GChain’s validator-based consensus ensures a **secure, scalable, and community-driven blockchain** with **lower gas fees and faster block times**, making it an efficient choice for decentralized applications.
