In the document, the bank describes the possible ways to implement a CBDC and the hypothetical consequences of different approaches. The report divides possible CBDCs in two categories, the first being those accessible to the general public in a form like banknotes, and the other as those limited for large-value settlements.
Moreover, after explaining that CBDCs of the latter kind wouldn’t bring many new features to the monetary system, the Japanese report’s authors focused on the first kind throughout most of the document. The report also noted that distributed ledger technology and blockchain could be used for a token-based CBDC.
As Cointelegraph reported in October last year, the deputy governor of Japan’s central bank, Masayoshi Amamiya, has expressed a negative stance towards central bank-issued digital currencies.
