Instead of step 1 and 2, you can click on the image, click on the three dots in the top-left corner, click on 'view original' and then copy the URL

I don't think this will work... It must be the original file. What you posted here and say "ricgh-click and save as.." is not the original. All the stego info was lost.
But is a nice and fun initiative :) you make people to use their brain and show PoW.

Edited now, with instructions to save the original. This works, I tested it. The nut is extractable and still unclaimed!

I think you do not understand. You edited that image file on your local PC with stego. Then you uploaded to a CDN https://i.ibb.co/...png. That means it lost all the stego info because you uploaded a copy, is not the original anymore.

No, that hoster does not re-compress PNG. I took the checksum (sha256sum) of the file immediately after saving in OpenStego. Then uploaded to hoster. Then downloaded from hoster. Took checksum again of downloaded file. Checksum matches. Exactly the same file.

ah ok that make sense. But you can put also directly the whole nut string inside, no need for a nut.txt file.
