DA Indexer Service

The DA Indexer service collects blobs from different DA solutions (currently only Celestia) and provides a convenient API for fetching blob data.

Celestia

The Celestia indexer runs on top of the Celestia light node. It is worth noting that the indexer collects only blobs and some block metadata, it does not collect full blocks, transactions, etc.

Troubleshooting

  1. Invalid tonic version
`Router` and `Router` have similar names, but are actually distinct types

To fix this error you need to change tonic version of tonic in blockscout-service-launcer to 0.8

For now you can only change in Cargo.lock
