Celestia introduces Ethereum fallback functionality for OP Stack and Celestia integration

ChainCatcher news, the modular blockchain Celestia announces support for the Ethereum fallback feature for the integration of OP Stack with Celestia, allowing Ethereum L2 (or L3) to "fallback" to using Ethereum calldata for data availability (DA) in the event of a downtime on the Celestia mainnet Beta. Once the interruption is resolved, L2 will automatically resume publishing DA to Celestia. The Ethereum fallback mechanism is currently implemented in celestiaorg/optimism v1.0.0 (OP Stack v1.0.0).
