#### Blob sidecars
#### Constructing Data column sidecars

The blob sidecars are no longer broadcast by the validator, and thus their
construction is not necessary. This deprecates the corresponding sections from
the Honest Validator specifications in the Fulu fork, moving them, albeit with
some modifications, to the [Honest Builder](./builder.md) specifications.
Unless a validator self-builds, the data column sidecars are no longer broadcast
by the validator, and thus their construction is not necessary.

thus their construction is not necessary

So this is still inaccurate. If validators can/will self-build, their construction is necessary.

This sentence needs a complete re-write in my opinion.

what about something like:

Data column sidecar construction and broadcast will be handled by builders. 

Validators will still have to construct and broadcast the data column sidecars if 
they choose to self-build.
