The European Central Bank (ECB) is considering the adoption of public blockchains such as Ethereum or Solana for its digital euro project. This strategic shift from a centralized ledger model comes as a response to recent U.S. stablecoin regulations, aiming to enhance interoperability with the broader crypto ecosystem and bolster monetary sovereignty. The ECB's decision on the blockchain framework is anticipated by late 2025, reflecting Europe's proactive stance in the evolving digital currency landscape.
