# Beacon Explorer
|
|
|
|
The Ethereum Beacon Chain Explorer consists of several Substreams modules showcasing the most basic operations that you can perform with Substreams on the Ethereum Beacon blockchain.
|
|
|
|
## Before You Begin
|
|
|
|
Make sure you have the [Substreams CLI installed](https://substreams.streamingfast.io/getting-started/installing-the-cli), and you know the [basic structure of a Substreams module](https://substreams.streamingfast.io/documentation/intro-getting-started/intro-evm). You must also provide a Pinax [API key](https://app.pinax.network) as `$SUBSTREAMS_API_KEY` environment variable
|
|
|
|
## Modules
|
|
|
|
The substreams package in this repository provides the following substreams modules:
|
|
- `map_block_meta` - streams some block metadata, such as slot number, root hash, spec version, timestamp, etc
|
|
- `map_block_full` - streams the entire block content to help you explore available fields
|
|
- `map_blobs` - streams blobs embedded into the beacon chain block
|
|
|
|
|
|
## Building the Substreams
|
|
|
|
First, generate the Protobuf code, which is the output of the Substreams:
|
|
|
|
```bash
|
|
> make protogen
|
|
```
|
|
|
|
Then, build the Rust code using the `cargo` command-line tool:
|
|
|
|
```bash
|
|
> make build
|
|
```
|
|
|
|
## Running Substreams modules
|
|
|
|
And now you can stream the corresponding substreams modules:
|
|
|
|
```bash
|
|
> make run map_block_meta
|
|
> make run map_block_full
|
|
> make run map_blobs
|
|
```
|
|
|
|
Alternatively, you can take advantage of `substreams gui` command for a nicer user interface:
|
|
|
|
```bash
|
|
> make gui map_block_meta
|
|
> make gui map_block_full
|
|
> make gui map_blobs
|
|
```
|
|
|
|
Or, you can just use `substreams` command to run it:
|
|
```bash
|
|
> substreams run -e eth-cl.substreams.pinax.network:443 map_block_meta -s -10
|
|
```
|
|
|
|
