My latest post for DMLcentral is up. Entitled Peering Deep into Future of Educational Credentialing it’s a look at how the blockchain technology that underpins crytocurrencies like Bitcoin could be used with the Open Badges Infrastructure [OBI].
If we used the blockchain for Open Badges, then we could prove beyond reasonable doubt that the person receiving badge Y is the same person who created evidence X. This would use a “proof of work” system. At the moment, the situation is still better than paper-based certificates but, such an approach would allow Open Badges to be used in extremely high-stakes situations. The blockchain would prove a connection between the evidence and the badge. More details could be unlocked if the earner chooses to share his or her key.
I’ve closed comments here to encourage you to add yours on the original post. Please do consider doing this as it raises awareness in the wider community.
You may also be interested to know that the xAPI (Tin Can) is now compatible with the OBI. This is less geeky and more interesting than it sounds!
