Public blockchains allow open participation, in contrast to private systems that restrict access to approved entities.

If adopted, this would mark a significant milestone for the digital euro, which still lacks a finalized technological framework.

Sources familiar with the matter note that EU officials are now taking public models more seriously.

A private approach, they said, would resemble China’s tightly controlled digital yuan, while a public model aligns more closely with U.S. firms like Circle, which issue widely accessible stablecoins.

Policymakers remain concerned about the growing dominance of U.S. dollar-backed stablecoins, which currently account for 98% of the global market.

ECB board member Piero Cipollone previously argued that a digital euro could help mitigate these risks by reducing reliance on foreign-issued assets.

While Ethereum and Solana are not officially confirmed, their consideration underscores a potential turning point in Europe’s CBDC strategy.
