Relatively short article describing blockchain and its use to record microcredentials. Most of the article is a straightforward outline of the technology and its uses. The most useful bit for me was the 'state of the art' section outlining a number of recent and current initiatives, including Stacks, formerly Blockstack, which adopted the Proof of Transfer Protocol (PoX). "Blockchain can also ensure the sustainability and accessibility of official credentials," writes Rory McGreal. "All the records are secured and permanent. This can become very important if an institution changes its name or even disappears." Image: PWD, via Rogers.
