29-36: This TryFrom implementation is acceptable.The conversion from
BlobtoOperationis straightforward and handles errors correctly.

114-145:
Theget_snarksmethod is decent but watch out for that hacky error handling.The method retrieves snark epochs correctly, but the hack for handling the "blob: not found" error is a temporary solution. Make sure to remove it once the Celestia node is updated.
146-187: Thesubmit_snarksmethod is solid, but the error handling is still a bit lacking.The method processes and submits multiple epochs efficiently. However, the error handling could be more robust, especially for serialization and blob creation errors.
189-214: Theget_operationsmethod is acceptable, but replace the placeholder error handling.The method retrieves operations correctly, but the placeholder error handling needs to be replaced with a more robust solution.

Just realized this is retarded, even though tests pass: We cannot be finalizing epochs every epoch_duration seconds. There is no epoch_duration in based sequencing. Epochs are not defined by us, but by the Celestia blocks. This means needing to:
Regardless, I will also add integration tests finally in this PR as well. That still will be done before RFR |
