Complete anonymity and integrity cannot technically be fully offered.
It is technically possible to build a value based CBDC that can be used anonymously, that is, without the payer having to identify herself when making a payment. A pre-loaded card could also be transferred to another person after purchase, in principle when cash changes ownership. However, this is not a question of a completely anonymous solution as a CBDC will always, due to its digital form, be possible to trace when used to make a payment. It must also fulfill the traceability requirements stipulated in the Money Laundering directive. In this way, the card will always be traceable to its buyer if it is used to make an electronic payment.
The conclusion drawn after discussions with market agents and agencies is that for a central bank digital currency to be accepted and widely available, it is vital to develop a technical user interface that is easy to use. One objective should also be to give those people who already find it difficult to manage digital services the opportunity to easily switch to using digital payment services. As the whole of society moves towards instant payments, high transaction capacity and performance will also be needed on the CBDC platform so that a large number of transactions can be settled without delay. It is also considered that the platform will also need to strengthen robustness on the payment market and make the services available even in situations when the telecommunications network is out of operation. In addition, the security requirements regarding hardware, software, architecture, and communication, as well as the requirements for maximum cybersecurity, will be crucial in the CBDC project’s future work. It is also considered that an account-based CBDC could rationalize payments from agencies and make them less dependent on commercial agents. Based on our drawn conclusion that it is appropriate to develop a CBDC platform based on existing FinTech, blockchain, and distributed ledger technology, as this is technology for the future.
