ABSTRACT
When developing peer-to-peer applications on Distributed Ledger Technology (DLT), a
crucial decision is the selection of a suitable DLT design (e.g., Ethereum) because it is hard
to change the underlying DLT design post hoc. To facilitate the selection of suitable DLT
designs, we review DLT characteristics and identify trade-offs between them. Furthermore,
we assess how DLT designs account for these trade-offs and we develop archetypes for
DLT designs that cater to specific quality requirements. The main purpose of our article is
to introduce scientific and practical audiences to the intricacies of DLT designs and to
support development of viable applications on DLT.

I wanted to share an article I wrote and appears in Educause this week. The focus is how higher education will need to adapt to meet the exacerbated and accelerated challenges brought by the current crisis.  Blockchain academic credentials offer a solution that not only addresses issues of fraud, student mobility and agency over their own records but also can provide valuable verification of significant learning experiences now captured in traditional paradigms of achievement and enhanced equity
