Peer-to-Peer Validation for Digital Euro Might Not Be Feasible, ECB Says

The ECB will examine using individual users to validate transactions offline, but “the time to market for this solution is more uncertain” than one involving traditional intermediaries like banks, given uncertainties over technology and security, the document said. “The development of a third-party validated solution for online payments should not be delayed in case the timely delivery of a peer-to-peer validated solution for offline payments proves to be unfeasible.”
