Celestia adds Ethereum fallback function support for OP Stack integration, allowing switching to Ethereum as DA in case of network failure

Modular blockchain Celestia announced support for the integration of OP Stack and Celestia with Ethereum fallback functionality, allowing Ethereum L2 (or L3) to fall back to using Ethereum calldata to obtain data availability (DA) when Celestia's mainnet Beta experiences downtime. 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) version.
