## **What is a Node Operator within Venn?**

Node operators run the core Venn infrastructure to validate transactions and ensure the network's overall functionality. The Venn node architecture is designed to run on your existing nodes or be deployed as a dedicated node, making it highly modular, cost-efficient, and easy to maintain. In the Venn ecosystem, there are two types of operators:

1. **Infrastructure Node Operators**: These operators focus on the technical infrastructure, ensuring the network runs smoothly and efficiently. Infrastructure operators can run the default threat model provided by Venn or choose any other threat model from any security team based on past performance and personal preferences.

2. **Security Node Operators**: These operators specialize in security validation, developing custom transaction analyses for potential threats and malicious activities. Security teams can integrate their unique threat models into the Venn node client using an SDK, allowing you to enforce specific security policies tailored to their expertise and approach.
