Exploring the EU’s Rapid Advancement in the Digital Euro Initiative
In a significant development, the European Union is accelerating its digital euro project. There’s a growing conversation among officials about potentially launching the digital euro on a public blockchain, with Ethereum and Solana emerging as frontrunners. This marks a departure from the initial closed, private system approach. This reconsideration follows the recent enactment of the US stablecoin law, known as the GENIUS Act, and an increase in dollar-denominated tokens, which have heightened Brussels’ concerns regarding the euro’s place in the evolving landscape of tokenized payments.
Reasons Behind the EU’s Consideration of Ethereum and Solana
The shift in strategy represents a significant change from the European Central Bank’s (ECB) previous focus on a tightly regulated infrastructure, managed by the Eurosystem and mediated by banks and payment providers. Officials within the EU privately acknowledge that the immediate catalyst for this change is the competitive pressure stemming from the US’s stablecoin framework and the widespread adoption of dollar tokens in commerce and markets. Opting for a public blockchain could enhance the reach and composability of the digital euro within the existing cryptocurrency economy, albeit with the challenge of managing policy trade-offs inherent in transparent, permissionless ledgers.

Strategic Perspectives from the ECB
Piero Cipollone, an ECB Executive Board member, has frequently highlighted the digital euro as a strategic countermeasure to reduce foreign reliance in payment systems. During a speech in Paris earlier this year, he emphasized that a central bank digital currency could lessen dependency on foreign providers, warning that the prevalent use of dollar stablecoins might undermine European banks’ revenues, data, and deposits.
Design and Implementation Considerations
According to the ECB, the digital euro aims to serve as a “digital equivalent of cash,” offering basic use for free, safeguarding user privacy, and ensuring universal acceptance across the eurozone. While these objectives are technology-agnostic, they require precise implementation. Achieving these goals on a public blockchain will depend on specific design elements like wallet and identity management, on-chain privacy (possibly through cryptographic methods), settlement finality, and maintaining a two-tier distribution system with monitored intermediaries on an open network. The central bank is still exploring various platforms and has not yet committed to a specific architecture.
The Promise and Challenges of Public Blockchains
Public blockchains offer seamless integration with the global crypto ecosystem, including programmable payments, tokenized deposits, and decentralized finance (DeFi) infrastructures, alongside robust liquidity and tooling. However, they also pose policy concerns that could be more easily addressed on a private ledger, such as transaction traceability versus user privacy, potential network congestion, outages, and governance issues like protocol updates, validator incentives, and miner extractable value (MEV), which a sovereign entity might prefer to control.
EU officials are currently navigating these complexities, aiming to prevent the euro from losing further ground to dollar tokens while upholding European standards for data protection and financial stability. No final decision has been made yet.
The Significance of the Digital Euro’s Underlying Infrastructure
The digital euro, regardless of the infrastructure choice, will remain a central bank liability, distinct from commercial stablecoins backed by reserves. It will be issued within the legal framework established by EU institutions. The current discussions focus on the infrastructure rather than the instrument itself. However, the choice of infrastructure is crucial. Selecting Ethereum or Solana would align the euro CBDC with the world’s leading token ecosystems, presenting both distribution benefits and regulatory challenges.
An endorsement of Ethereum or Solana by the EU would be a significant catalyst for these platforms, signaling that public blockchains have achieved a level of maturity suitable for institutional use.
Conclusion
As the EU deliberates on the best path forward for the digital euro, the decision on whether to leverage public blockchains like Ethereum or Solana will have far-reaching implications, not only for the euro’s role in the global economy but also for the broader acceptance of public blockchains in institutional finance. As of now, the journey continues with no definitive resolution, but the potential for a transformative impact is undeniable.
