Thomas Mayer former chief economist of Deutsche Bank proposes in FT that Europe create a bloackchain backed digital euro. "Digitalization offers a way to reduce the debt of the eurozone states and to safeguard the euro."
"A digital euro issued by the ECB would not only be stronger but could compete with the dollar as well as other digital money to become a global reserve currency. Central bankers are conservative by nature and averse to experiments. But with their backs against the wall, they will soon have no other choice than to contemplate experimental medicine to save the euro from breaking apart in a recession."
