Want to become a node operator on the APRO network? This isn’t just a simple investment—you’re actually participating in building the foundational infrastructure for trillion-dollar data authenticity verification. Put simply, you’re the “foundation” of this decentralized network. So how do you get started and begin earning $AT tokens? Let’s talk about the practical steps.

**First, figure out which role suits you**

The APRO network has three types of node roles, each with completely different resource and capability requirements:

**Data Source Node**—This is for players with real “substance.” If you have access to authoritative data channels (for example, you’re a data service provider, financial institution, or API provider), this role is for you. The hard requirements are stable data interfaces and enterprise-level security protection, since the data you provide will be verified by the whole network.

**Validator Node**—The main battleground for tech communities and staking service providers. You’ll need a reliable cloud server (don’t use an old computer at home), stable internet, and some basic operations and maintenance knowledge. The entry barrier is relatively friendly, perfect for those who want to earn long-term staking rewards.

**Execution Node**—The stage for multi-chain developers. You’ll need to be able to deploy lightweight clients on different blockchains and be familiar with cross-chain environments. This is the most technically demanding role, but the rewards are also more substantial.

**How to clear the token staking hurdle**

The first step is to acquire $AT tokens. Buy them on a compliant exchange, then transfer them to your own non-custodial wallet (MetaMask is a safe choice). Next, open APRO’s official node portal, connect your wallet, and choose the type of node you want to run.

The staking threshold isn’t fixed—the network dynamically adjusts it based on security requirements and data value. The good news is that early participants are usually incentivized, essentially giving you an “early bird discount.” Lock up the required amount of $AT in the contract, and you’ve got your entry ticket.

**Don’t make mistakes during software deployment**

Follow the official documentation to install the corresponding node software package on your server. Pay attention during the configuration step: you’ll need to input your wallet private key to authorize node operations (make sure to manage your private key securely and don’t leak it).
