Blobstream for validators ​

Blobstream allows Ethereum developers to build high-throughput L2s using Celestia, the first data availability layer with data availability sampling.

This page and following tutorials will go over Blobstream and how validators on Celestia can run it.

If you're looking to learn more, you can view the orchestrator-relayer repository or read more about how Blobstream works.

Install the Blobstream binary ​

The orchestrator is the software that signs the Blobstream attestations, and the relayer is the software that relays them to the target EVM chain.

The following sections in this category presume you have the following setup:

• A celestia-app validator node running
• The following hardware minimum requirements for running the orchestrator:
  • Memory: 2 GB RAM
  • CPU: 1 core
  • Disk: 10 GB SSD Storage

Install ​

1. Install Go 1.21.4

2. Clone the https://github.com/celestiaorg/orchestrator-relayer repository:

   bash

   git clone https://github.com/celestiaorg/orchestrator-relayer.git
   cd orchestrator-relayer
   git checkout v1.0.1

   git clone https://github.com/celestiaorg/orchestrator-relayer.git
   cd orchestrator-relayer
   git checkout v1.0.1

   These commands check you out to: v1.0.1 of @celestiaorg/orchestrator-relayer

3. Install the Blobstream CLI

   sh

   make install

   make install

Usage ​

# Print help
blobstream --help

# Print help
blobstream --help

Next steps ​

1. If you are a Celestia validator, all you need to do is run the orchestrator. Check out the Blobstream orchestrator page for more details.
2. Learn about key management
3. Optional: If you want to post commitments on an EVM chain, you will need to deploy a new Blobstream contract and run a relayer, or run a relayer for an already deployed Blobstream contract. Check out the Blobstream relayer page for relayer docs and the Blobstream deployment page for how to deploy a new Blobstream contract.
4. Optional: Learn how to run a Blobstream bootstrapper node
