- Main event indicates the EU’s blockchain consideration.
- EU plans to leverage public blockchains.
- Ecosystem response to this blockchain pivot.

The European Union is actively progressing its digital euro initiative and is considering implementing it on public blockchains like Ethereum and Solana. This approach represents a shift from closed systems previously favored, potentially impacting Ethereum and Solana networks with increased interest.
The EU’s exploration of Ethereum and Solana represents a fundamental shift in central bank digital currency strategies, highlighting potential blockchain roles in the digital euro’s infrastructure.
The European Central Bank (ECB) is leading this initiative, alongside high-level EU financial authorities. The digital euro prototype is expected by 2025, which could involve Ethereum or Solana’s public blockchains. This move diverges from prior preferences for closed systems.
“EU officials now view public blockchain adoption as essential for ensuring digital euro relevance in global markets. Ethereum presents compelling advantages through its established developer ecosystem and recent scalability improvements… Recent operational improvements on Solana have addressed many technical concerns, yet institutional perception often lags measurable performance metrics.” – EU Technical Advisor, European Union Technical Advisory, paraphrased summary [source: Official project notes]
Ethereum and Solana, key players in the blockchain ecosystem, may experience significant impacts, with implications for their stakeholders and strategic blockchain applications. As the ECB considers public chains, speculation grows concerning asset implications on ETH and SOL, alongside DeFi and infrastructure considerations.
Potential financial shifts and regulatory developments loom, with institutional and market frameworks possibly influencing blockchain deployments. Historically, CBDC pilots have opted for permissioned blockchains, marking the EU’s consideration of public options as noteworthy.
Public blockchains could enhance the global competitiveness of EU digital assets, fostering interoperable financial systems. Solana and Ethereum could thus boost transaction efficiency and scalability. However, this raises underlying technological challenges and regulatory considerations. Providing robust infrastructure scalability and addressing institutional trust will be crucial in Europe’s broader digital euro strategy.
