I noticed that the badges reflect only your behavior within the platform, not your actual achievements.
For example, if I complete a course or set of exercises in C#, Python, etc., I want to be able to display that on my LinkedIn with a verifiable link (using the Open Badges standard, for instance). Anyone who clicks it would be taken to my badge’s link and could verify that I completed the entire language track—or see the percentage I finished, and so on.
I don’t know if the badges would be taken seriously in practice, since it would be easy for someone to get them by “cheating”.
Even official exams (Microsoft, Oracle, etc.) can be cheated on.
However, we have two distinct categories of badges:
1 - Exam-based = validates your knowledge;
2 - Course-based = confirms that you have at least a basic understanding of the topic;
In my experience, when you take a Microsoft exam, they do a check to rule out at least the naive methods of cheating. I was asked to turn on the camera and show the room to confirm I was alone, and they told me there was a problem because I had AnyDesk running. I think I shut it down.
Funny thing is, I didn’t even know what it was at the time. My own laptop had decided to malfunction on the day of the exam, and I had borrowed my sister’s at short notice; she had AnyDesk for her work. Just imagine if I’d been disqualified because of that 
But if it’s understood that a course-based badge only guarantees that you took the course, not necessarily having passed a test, then count me in.
BNAndras's profile on Exercism shows my published solutions and can be filtered to a track like C# to show what I’ve done there.
So hypothetically Exercism might be able to structure a set of pages for each track a student is enrolled in. That shows whether they have completed the track since joining/resetting, the number of exercises they currently solved, and the general difficulties of those exercises. You could report when the exercises were done and if they had mentoring and when. If a track has a learning mode, you could report out what concepts have been unlocked and which are locked.
That’s all information that can’t be readily gleaned from the public profile so there’s some utility in having something like this whether it’s a badge or just a shareable page. However, we need to be careful and not overstate what this information means. It’s not an industry-specific certification or a teacher-led course, both of which carry specific meaning. This setup would be Exercism verifies that X did these specific things in Y track and the reader decides for themselves how much weight to give these achievements. This doesn’t fit for a badge, but it’s still something you might be able to link to on your LinkedIn profile.
