One of our OEGlobal Board members, Perrine de Coëtlogon, is in charge of Blockchain & Open Education within the Directorate for Pedagogical Innovation of the University of Lille and represents France within the European Blockchain Partnership. They run a a Blockchain, Open Education & Digital Citizenship conference (
https://blockchaineducationfrance.fr/programme/) and (
https://eraser.medium.com/blockchain-open-education-digital-citizenship-eac61c051134). I expect many of the speakers may have OER related to this topic.
Rory McGreal, a UNESCO OER chair, is also working on the topic of OER and Blockchain and will be presenting on this at the upcoming
OEGlobal online conference at the end of September.
Alexander Mikroyannidis is also working on this and will be presenting on Decentralising Open Education Using Blockchain Technology at the
OEGlobal online conference in September.
I'm not sure to what extent these folks actually have OER on Blockchain but worth exploring.
Hope this helps.
