What is ethda? can you elaborate a full description of the PR?

gm! After a team discussion we're reconsidering the idea of adding the different DA protocol integrations directly on this repo. Instead we'd like this code to live on a repo you fully own, and for it to be imported here as an external dependency.

In a nutshell, this PR should only contain the modifications done on:

• cmd/run.go
• dataavailability/config.go

Anything else should be handled on a repo of yours. Sorry for the confusion, and the last minute change of mind, but we believe this will be better for everyone

Hi arnaubennassar & vcastellm, sorry for late reply. EthDA by itself is an Ethereum zk rollup built with Polygon CDK, and is targeted to sever as an Alt-DA solution for other CDK validiums, just as Celestia or Avail does. You could find more info in our website.

This PR is to support starting a CDK validium with EthDA as DA layer (instead of DAC nodes). And thanks for your illustration, we will continue to update the PR following your guidelines.

@arnaubennassar Hi arnaubennassar, thank you for your reply. We have extracted the EthDA-related code into a separate library. The current changes now only involve cmd/run.go and dataavailability/config.go. Looking forward to your review.
