according to sources familiar with the matter cited by the Financial Times on Friday, the European Central Bank is considering running a digital euro on public chains such as Ethereum, rather than private chains. Unlike private chains where data is strictly limited to authorized entities, public chains like Ethereum or Solana are open to everyone. Given that the European Central Bank has not yet finalized the technical framework for this project, if confirmed, the EU's exploration of public chains will be an important milestone in the development of the digital euro. Another source said that a private form of digital euro "looks more like the approach of the Chinese central bank than that of American private companies." This source specifically mentioned China's central bank digital currency (CBDC), which is privately deployed, contrasting with public stablecoins developed by companies like Circle. The European Central Bank has not publicly confirmed whether it is considering Ethereum or Solana.
