# Operate

> Run a Stable node. Install, configure, monitor, and upgrade.

Operate covers running a Stable node: full or archive, testnet or mainnet, from install through monitoring. For the chain-level behavior your node enforces (fee model, finality, USDT0 as gas), see [Gas pricing](/en/explanation/gas-pricing), [Finality](/en/explanation/finality), and the [Architecture overview](/en/explanation/core-optimization-overview).

## Node types

### Full node

A full node maintains a complete copy of the blockchain and validates all transactions and blocks. Full nodes:

* Verify all transactions and blocks
* Maintain the entire blockchain history
* Can serve data to other nodes
* Support the network's decentralization

### Archive node

An archive node stores the complete history of all states and can serve historical queries. Archive nodes:

* Store all historical states
* Support historical queries at any block height
* Require significantly more storage
* Essential for block explorers and analytics

## Network information

For complete network details including RPC endpoints, block explorers, and chain parameters, see:

* **[Mainnet](/en/reference/mainnet-information)** - Mainnet details
* **[Testnet](/en/reference/testnet-information)** - Testnet details

## Quick start

For experienced operators who want to get started quickly:

1. Check [System Requirements](/en/reference/node-system-requirements)
2. Follow the [Installation Guide](/en/how-to/install-node)
3. Configure your node using [Configuration Guide](/en/reference/node-configuration)
4. Speed up sync with [Snapshots](/en/how-to/use-node-snapshots)
5. Monitor your node with [Monitoring Guide](/en/how-to/monitor-node)

For network parameters and RPC endpoints, see [Mainnet Information](/en/reference/mainnet-information) or [Testnet Information](/en/reference/testnet-information).

## How node ops connect to the chain

Running a node means enforcing Stable's chain-level rules. These pages explain the behavior your node implements:

* **[Contracts overview](/en/explanation/contracts-overview)** covers the fee model, JSON-RPC surface, and system modules your node serves.
* **[Finality](/en/explanation/finality)** explains single-slot finality and what "confirmed" means at the consensus layer.
* **[Architecture overview](/en/explanation/core-optimization-overview)** walks through consensus, execution, database, and RPC layers.
* **[Gas pricing](/en/explanation/gas-pricing)** explains how USDT0-denominated fees are priced and collected.
