we could probably collect a few different scattered resources around how, and why, the share commitment is created. We info from the above links listed in this discussions, the code here and here, the rational, and in the blob readme

The title of the issue "Add more examples of programmatically signing, parsing, and proving PFBs" implies that there are existing samples for signing, parsing and proving PFBs. It would be useful to provide a link to these existing samples, if available. Thanks!

hmm I don't think we have any existing examples. My best effort for existing resources:

1. https://docs.celestia.org/developers/node-tutorial/#submit-a-pfb-transaction
2. https://gist.github.com/rootulp/3e966bba69ef3d748cd9cb0c1c2f21eb#submit-a-pfd

3. celestia-app/x/blob/payforblob.go

   func SubmitPayForBlob(

4. celestia-app/x/blob/client/cli/payforblob.go

   Line 21 in 2d6cdf0

   func CmdPayForBlob() *cobra.Command {

Removing my assignment from this issue due to its low priority and the likelihood that we won't address it in the near future. I will reassign it as soon as we reprioritize it.
