Celestia supports the deployment of Arbitrum Orbit chain on the mainnet

Celestia supports the deployment of Arbitrum Orbit chain on the mainnet, allowing developers to use Celestia's data availability for their custom L2 or L3 chains. This integration is supported by Blobstream, a one-way data verification bridge that can transmit the data stream from Celestia's data availability layer to the Arbitrum Orbit chain. Blobstream allows validation of Celestia's data roots through an on-chain light client on Ethereum L1, enabling chains to access block space priced independently of its underlying chain-based Gas costs. In addition, this integration also has an Ethereum fallback feature, allowing rollups to rely on Ethereum's data availability.
