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, and you know the basic structure of a Substreams module. You must also provide a Pinax API key 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:

> make protogen

Then, build the Rust code using the cargo command-line tool:

> make build

Running Substreams modules

And now you can stream the corresponding substreams modules:

> 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:

> make gui map_block_meta
> make gui map_block_full
> make gui map_blobs

Or, you can just use substreams command to run it:

> substreams run -e eth-cl.substreams.pinax.network:443 map_block_meta -s -10

Endpoints

Pinax offers the following beacon chain substreams endpoints:

eth-cl.substreams.pinax.network:443
gnosis-cl.substreams.pinax.network:443
sepolia-cl.substreams.pinax.network:443
holesky-cl.substreams.pinax.network:443
chiado-cl.substreams.pinax.network:443
