# How Guardian Node works?

The Hela Guardian Node network comprises up to 50,000 decentralized nodes tasked with monitoring and validating the health and performance of various servers and systems within the Hela ecosystem.

Each node operates independently, interacting with designated machines and tasks, and reporting its findings to a central backend system.

This data is subsequently integrated into the Guardian Node Smart Contract, providing a real-time snapshot of the network's health.

**Guardian Node vs. Validator Node vs. Client Node**

| Feature                  | Validator Node                 | Guardian Node                              | Client Node                             |
| ------------------------ | ------------------------------ | ------------------------------------------ | --------------------------------------- |
| **Produces Blocks**      | ✅ Yes                          | ❌ No                                       | ❌ No                                    |
| **Validates Consensus**  | ✅ Yes                          | ✅ Yes (indirectly, by checking validators) | ❌ No                                    |
| **Supports ParaTime**    | ✅ Yes                          | ✅ Yes                                      | ✅ Yes                                   |
| **Slashing Risk**        | ✅ Yes                          | ❌ No (only watches)                        | ❌ No                                    |
| **Hardware Requirement** | High (CPU, RAM, uptime)        | Medium                                     | Low                                     |
| **Best For**             | Stakers, heavy infra providers | Security-conscious devs, watchdogs         | dApp developers, explorers, light users |
