Ethereum News Today: EU May Embrace Ethereum, Solana for Digital Euro—A New Era in Sovereign Crypto

The European Union is reportedly considering public blockchain networks, including Ethereum and Solana , to underpin its upcoming digital euro. This development marks a potential shift from the private or permissioned blockchain models that have historically been favored for central bank digital currencies (CBDCs). According to a recent Financial Times report, the European Central Bank (ECB) is actively assessing whether to deploy the digital euro on a public blockchain infrastructure, which could position the EU among the first jurisdictions to explore open blockchain architecture for a sovereign digital currency [1].

The move reflects a broader re-evaluation of blockchain technology within the ECB, where the advantages of public blockchains—such as decentralization, transparency, and global accessibility—are being weighed against the more controlled and restricted nature of private blockchains. Public blockchains like Ethereum and Solana are already widely used in the crypto industry for stablecoins, decentralized finance (DeFi) applications, and digital asset issuance, offering a stark contrast to private systems where access and data visibility are limited to a select few institutions [1].

This proposed pivot aligns the EU more closely with U.S. market-driven stablecoin initiatives, such as those from Circle (issuer of USDC) and Paxos (issuer of PayPal USD), which operate on transparent blockchains with verifiable reserves and smart contract automation. In contrast, the People’s Bank of China’s digital yuan operates on a centralized, permissioned system, a model that some European policymakers are now keen to avoid, particularly in light of concerns around privacy, transparency, and financial competition [1].

The ECB’s interest in Ethereum and Solana also reflects a growing concern among European regulators about the dominance of U.S. dollar-backed stablecoins. ECB Executive Board member Piero Cipollone has warned that the U.S. dollar accounts for 98% of the stablecoin market, raising long-term risks for European monetary sovereignty and local financial autonomy [1]. Cipollone emphasized the need for a euro-denominated alternative to reduce dependency on foreign financial infrastructure and to secure Europe’s digital monetary future [1].

Ethereum and Solana offer distinct technical and architectural advantages. Ethereum, with its strong security, decentralization, and widespread institutional trust, is already supporting major euro-pegged and USD-pegged stablecoins. Solana, on the other hand, is noted for its low transaction fees and high throughput, making it appealing for consumer payments and high-volume settlements. The ECB is currently evaluating the trade-offs between speed, decentralization, and compliance across these platforms [1].

Despite the potential for a public blockchain-based digital euro, privacy and governance remain key concerns. While public blockchains offer transparency, they also expose transaction data, which could raise surveillance and consumer protection issues. To address these, the ECB may integrate privacy-preserving technologies such as zero-knowledge proofs or interoperable privacy layers. Additionally, the ECB is expected to maintain strict Know-Your-Customer (KYC) and Anti-Money Laundering (AML) rules, aligning with existing financial regulations [1].

The ECB has committed to a prototype and limited pilot of the digital euro by late 2025, with broader deployment discussions scheduled for 2026. The exploration phase is part of a broader consultation process launched in 2021, involving national central banks, EU legislators, and private sector partners. To date, trials have focused on offline payments, programmability, and cross-border use cases, with participating banks showing support for hybrid models that combine public infrastructure with central oversight [1].

A decision by the EU to adopt Ethereum or Solana would represent a historic endorsement of public blockchain technology by one of the world’s most influential monetary authorities. It could set a precedent for other jurisdictions, particularly in regions where public chains are already being used for remittances, tokenized assets, and mobile-first financial services. The move could also accelerate regulatory clarity for public chains in Europe, enhancing on-chain euro liquidity and fostering institutional participation in DeFi [1].
