# Earning Mechanism

Openledger offers a dynamic and evolving rewards structure to incentivize contributions 

### **Testnet Earnings**

1\. **Network Earnings**: Earn points by running nodes and actively contributing to the testnet infrastructure.

2\. **Referral Earnings**: Invite others to join as node operators and earn static rewards for successful referrals.

3\. **Bonus Earnings**: Additional points rewarded during specific events, milestones.

### **Node & Heartbeat Rules**

* **Node Limit:** Each user is limited to 3 active nodes at a time.
  * This can include **2 mobile devices + 1 browser extension**, or **3 mobile devices**.
  * Using more than 1 browser extension simultaneously will **disable heartbeat rewards**.
* **Extension Restriction:** Only one extension node is eligible to receive heartbeat points. If logged in on multiple extensions, heartbeat will not be credited.
* **Heartbeat Credit:** Heartbeats are credited **every 5 minutes** per eligible node.

These testnet rewards pave the way for a thriving mainnet ecosystem, giving participants a head start in understanding and contributing to Openledger’s decentralized AI network.
