At the end of October, the BIS published an updated document on mBridge showing that, in addition to the five principal participants, 25 other official entities have signed on as observers. These include the IMF, the World Bank and the central banks of 23 countries, including Saudi Arabia, Turkey, South Africa, Namibia, Malaysia, France, Italy, Norway, Chile, Australia… every continent has representation. Even the U.S. central bank is present, via the Federal Reserve Bank of New York. The European Central Bank is also in the group. Observers have access to a “sandbox” for experimentation. According to the BIS, 11 have been taking advantage of this.
