IBM has some ideas about what it will take to make the digital euro a success, which it shared in a recent blog post. It suggested five items for designers to help the European Central Bank digital currency “enter the highly competitive, multifaceted, and heterogeneous payments landscape in the Eurozone.”
Some of the IBM points are already found in the European Commission (EC) legislative proposal. “Build on existing rails,” the first point, is already foreseen in the EC plan, although it can be extended, the five authors said. Simplicity will be key to initial adoption, they reasoned, and familiarity reinforces that.
Intermediaries will also have a role to play in digital euro acceptance, and the digital currency should be designed to accommodate their needs:

The EC proposal includes strong offline privacy guarantees that could be extended to online activities to ensure end-to-end transaction privacy, IBM suggested. The proposed legislation offers privacy measures “consistent with current digital payment’s privacy levels.” IBM said privacy rules need to be harmonized with several existing regulations, including reporting thresholds, to ensure that reporting is siloed.
Distributed ledger technology is not essential for the creation of a digital euro, the authors noted, but blockchain technology offers the most benefits. Its operation need not be any more carbon-intensive than non-blockchain systems, they added.
Finally, go slowly but surely, IBM advises. Start with a minimal viable product for faster time to market and a sandbox to deal with the great complexity of the future digital euro’s operating environment.
