# Get Started

When you need blockchain data or want to send transactions, you’ll need access to a blockchain node. At that point, you can either use an [external node service](/giwa-chain/en/tools/node-providers.md) or operate a GIWA node yourself.

{% hint style="warning" %}
Running a blockchain node consumes significant time and resources. If only using RPC meets your needs, there’s no need to run your own node.

Need RPC for testing? Try the free endpoint provided by GIWA.

* Testnet (Sepolia): <https://sepolia-rpc.giwa.io>

Free endpoints are rate-limited. For production apps, we recommend using an [external node service](/giwa-chain/en/tools/node-providers.md).
{% endhint %}

## Prerequisites

### Hardware

| Resource | Minimum       | Recommended |
| -------- | ------------- | ----------- |
| CPU      | 4 cores       | 8+ cores    |
| RAM      | 8 GB          | 16+ GB      |
| Disk     | 500 GB (NVMe) | 1+ TB       |

### Layer 1 (Ethereum) RPC

Since GIWA is an Ethereum Layer 2 blockchain, a GIWA node requires an L1 (Ethereum) RPC to function properly. For the Ethereum node, you can either use an external node service or operate one yourself.

## Run a Node

Clone the GitHub repository [giwa-io/node](https://github.com/giwa-io/node) and follow the README guide.

After the node starts, catching up to the latest GIWA chain tip is called syncing. Syncing can take a long time. You can check the node's sync status with the command below.

```bash
curl http://localhost:8545 \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"eth_syncing","params":[],"id":0}'
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.giwa.io/giwa-chain/en/node-operators/get-started.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
