Table below summarizes the role of relevant flags in Lighthouse beacon node:
| | Post-Deneb, Pre-Fulu || Post-Fulu ||
|-------|----------|----------|-----------|----------|
| Flag | Usage | Can serve blobs? | Usage | Can serve blobs? |
| --prune-blobs false | Does not prune blobs since using the flag | Yes, for blobs since using the flag and for the past 18 days | Does not prune data columns since using the flag | No |
| --semi-supernode | - | - | Store half data columns | Yes, for blobs since using the flag for a max of 18 days |
| --supernode | - | - | Store all data columns | Yes, for blobs since using the flag for a max of 18 days |

While both `--supernode` and `--semi-supernode` can serve blobs, a supernode will be faster to respond to blobs queries as it skips the blob reconstruction step. Running a supernode also helps the network by serving the data columns to its peers.
