I have a quesion on Open Badges.
Are there any way to implement Open Badges without Blockcerts?
If so, I wonder how can I ensure security?
I mean how to prevent forgeries and / or falsifications?
I really appreciate if anyone help me.
Blockcerts v2 is an extension of the Open Badges standard.
If you want to work with Open Badges and not Blockcerts here is unfortunately not the relevant place to get this information. I would suggest you look through the specs there: https://openbadges.org/
