I'm not an expert in open badges, but dealing with Open Educational Resources (#OER), Open Educational Practice (#OEP) and the question how to make #openness the default in teaching and learning - focus on Germany.
@xldrkp I'm no expert either! I like the idea of openness in education, though and I have produced many OERs (in the form for video tutorials hosted on YouTube).
I think blockchain has the potential to add credibility and validity to badges, but I have to be honest, I know very little about it. I suggest maybe asking Doug Belshaw for views on blockchain. @dajbelshaw
@xldrkp @omanreagan @TheWayneGibbons Basically, blockchain-based digital credentials (including MITs Blockcerts, which are compatible with the Open Badges standard) are fine, but the use case, as far as I see it, is super high-stakes testing.
For everything else, regular Open Badges provide enough evidence and verification.
There's other useful things about blockchain, but immutability can have its downsides too...
