Odaily Planet Daily News: Germany's second-largest exchange, Boerse Stuttgart Group, has completed a secondary market trading test using blockchain technology in cooperation with the European Central Bank (ECB). According to a press release, this development marks the first time that the group has "settled exchange transactions with central bank currencies using blockchain-based securities" and "the settlement scheme is linked to the trigger solution of the German Central Bank (Deutsche Bundesbank) and is therefore also linked to the traditional euro payment system." The test is part of the ECB's exploration of blockchain technology and involves six partner banks: Commerzbank, Deutsche Bank, DZ Bank, LBBW, Bankhaus Metzler and V-Bank. Using Boerse Stuttgart Group's blockchain-based settlement solution, the institutions tested various transactions involving five tokenized securities, including bonds, funds and stocks.
