Manuel Klein, Product Manager Blockchain Solutions and Digital Currencies from Deutsche Bank
The investigation phase has revealed that a potential retail CBDC will be based on a centralised infrastructure, hosted by the ECB, therefore Blockchain technology will most likely not be used. The Eurosystem has, however, experimented with an innovative token-based backend infrastructure which could allow digital Euros to be token-based and hence similar to physical cash which is also not account-based. The ECB has stated that transactions must be free for end-users. It will, however, be possible for intermediaries who process transactions to generate revenue. This will be achieved through merchant fees for the acquirer and interchange fees for the issuing bank.
Once a retail CBDC transaction is settled, the money will be credited, up to the maximum holding amount set by the ECB, to a recipient’s wallet. To prevent large liquidity outflows from the banking system, merchant wallets will always have a zero intraday and overnight holding capacity. Enterprises that accept digital euro transactions, will therefore immediately and automatically, have these funds ‘defunded’ to their regular bank accounts at a commercial bank. “The digital euro cannot be held and used as a form of payment for corporates and merchants,” Klein emphasised.
