# INTMAX Block Builder

The INTMAX Block Builder is the node responsible for aggregating user transactions and submitting new L2 blocks to the network.

Running a builder lets you:

* **Earn rewards by helping finalize blocks.**
* **Strengthen decentralization by contributing new permissionless capacity.**

| **Full-Network Mode** | When the Builder cannot be accessed publicly (behind NAT or firewall). Traffic is relayed through the INTMAX proxy. | Quick, one-command installation without domain or load balancer setup.                                                       |
| **Standalone Mode**   | When the Builder can be made publicly accessible using your own domain or load balancer.                            | Minimal or customizable installation, best for production-grade and flexible setups, supports multiple independent Builders. |
