Recently, an Italian bank published a research report detailing a comprehensive study on Distributed Ledger Technology (DLT). Within this report, the bank introduced an optimized version of a permissioned consensus protocol designed specifically to better fit within the Bitcoin ecosystem. A key innovation in this permissioned version tailored for Bitcoin, it not only enhances system security but also opens up new possibilities for central banks to construct their own DLT systems. By pursuing this work, the Italian bank is actively driving digital transformation in finance, exploring how DLT technology can be leveraged to enhance financial efficiency and security.
