orchestrator-relayer

Contains the implementation of the Blobstream orchestrator and relayer.

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

For a high-level overview of how Blobstream works, check here and here.

Install

1. Install Go 1.21.1
2. Clone this repo
3. Install the Blobstream CLI

make install

Usage

# Print help
blobstream --help

How to run

If you are a Celestia-app validator, all you need to do is run the orchestrator. Check here for more details.

If you want to post commitments on an EVM chain, you will need to deploy a new Blobstream contract and run a relayer. Check here for relayer docs and here for how to deploy a new Blobstream contract.

Note: the Blobstream P2P network is a separate network than the consensus or the data availability one. Thus, you will need its specific bootstrappers to be able to connect to it.
