Can a zkSnark be shared via the snarketplace

It sounds silly, but humor me for the moment.

Here I am asking whether the following is possible, rather than supported:

  • I generate a zks for a txn
  • distribute it to someone else
  • they also upload it to the snarketplace, obviously for the same txn (would they need to edit/amend it in any way??)
  • that txn now has two zks listed as available for it

I am happy to entertain the scenario where both parties have to be sophisticated and even abuse the tooling in order for this to be done.

I haven’t yet found a document reference but will update this when I do.
