Odaily News It is reported that JPMorgan Chase, Deutsche Bank and BNP Paribas are working together with the European Central Bank to promote tokenization, which is testing the use of blockchain technology to settle securities transactions. The ECB's tokenization trial began in December last year and is still in its early stages and will continue until November this year. Ulrich Bindseil, director of market infrastructure and payments at the ECB, said when the tokenization trial was first announced in December last year: "We are trying to look to the future and think about how the form of central bank currency can maintain its use."
