The European Union is exploring the use of public blockchains like Ethereum and Solana for its digital euro project, marking a shift from considering private blockchain solutions.
This move is driven by the need to keep pace with global developments, especially following the US passing stablecoin regulations that could threaten the euro's competitiveness in international finance.
Ethereum and Solana are being evaluated for their specific strengths: Ethereum offers a mature, secure environment with a large developer community and robust tooling, while Solana is known for its high throughput and low transaction costs, making it well-suited for processing millions of transactions daily. The EU aims to balance security, scalability, cost efficiency, and developer support in selecting the right platform.
The shift toward public blockchains reflects a strategic acknowledgment of their benefits, including transparency, innovation potential, and system resilience. However, challenges remain, such as regulatory integration, scalability, privacy concerns related to transparent public ledgers, and interoperability with existing banking infrastructure.
This exploration could position the digital euro as a global model for central bank digital currencies (CBDCs), influencing the future of digital finance and crypto adoption worldwide. The urgency of this shift is underscored by the rapid progress of other nations, like the US and China, in digital currency initiatives, as well as concerns about the dominance of the US dollar in digital payment systems.
This EU's consideration of Ethereum and Solana highlights a bold move to leverage established public blockchain technologies for its digital euro, with potential impacts on financial systems and digital currency standards globally.
