Barclays released a paper titled ‘An Illustrative Industry Architecture to Mitigate Potential Fragmentation across Central Bank Digital Currency and Commercial Bank Money’. Hackathon participants will code solutions to a series of challenges that involve connecting to a Barclays simulation of both a central bank API and commercial banks APIs, shown in the diagram below from the Barclays paper.
