A recent study released by the Bank of France discussed the possibility of the European Central Bank launching a CBDC. Studies have shown that the issuance will depend on the selected asset criteria, as it needs to be integrated into existing regulations to avoid a revision of the legal text. If the issuance of the CBDC goes beyond "technical processes", the ECB will have two main options to facilitate implementation. The first option is to equate the CBDC with a digital banknote, which will allow the CBDC to function as and mirror the banknote. This situation will greatly limit and limit the characteristics of the CBDC; the second option will allow tokenized assets as currency Business collateral is accepted.
