Assuming cooperation with DLT

In the result report of this time, there is an item called “peripheral functions for cooperation between intermediary institutions and external systems”. In that item, the Bank of Japan said, “The external systems to be linked may not only be based on existing technologies, but may also be based on new technologies such as distributed ledger technology (DLT). ‘ said. DLT generally includes blockchain.

The Bank of Japan said, “In overseas CBDC demonstration experiments, there are also cases of collaboration between CBDC systems and DLT platforms, with an awareness of so-called asset tokenization, in which assets are tokenized and distributed on a platform that utilizes DLT. There are many.”

Therefore, in the proof of concept of the Bank of Japan, when considering the exchange of assets on the CBDC and DLT platforms, the assets to be exchanged are once secured in each system, and if the securement is successful in both systems, the final exchange is performed. It is explained that it is assumed that processing interlocking with maintenance (escrow) is assumed.
