I think this is the list so far of things that should be done:
For accepting blocks:

• Parsing transactions requires new SSZ encoding Shard blob transaction encoding #4783
• • We need to refactor the current Transaction encoder that is tightly coupled with the current way of encoding and make it more generic
• • We need to find out if we can reuse what Teku has in Teku codebase
• Integrating with c-kzg
• • stefan.bratanov has a repo
• • Integration with the c kzg library to check commitments for a block to validate it. One aggregate commitment over all transactions in block must be calculated for this to be done.
• EVM has access to the commitments (not blobs) so that has to be handled
• Precompiles

For creating new blocks:

• We must work on new transaction gossip. The eth/68 I think specifies that the new transaction will be only advertised but not pushed to peers. We need logic to retrieve these transactions with blobs. There is a PR for eth/68 Implement eth/68 (EIP-5793) #4730
• Transaction pool needs updates (maybe new transaction pool must be created) to handle new types of fees for blobs
• Transaction commitments must be checked per transaction
• We need a short-term storage mechanism for blobs. When a new block gets produced, EL is responsible for storing the blobs until CL asks for them
• New APIs to provide blobs to CL

We could save bandwidth for non-validator nodes and not download any data blob transactions at all. Only validator nodes that need to create blocks need to do that. Right now Besu does not know if it is a validator or a non-validator node. It could make sense to tell Besu via config if it is one or not. For example something like --mode=[VALIDATOR,NONVALIDATOR,..]
