The current scalability of Ethereum and Solana put in check that are used for a CBDC. EU accelerates the digital euro after Genius Act, the US law on Stablecoins. The European Union (EU) accelerates its plans for the creation of a digital euro, a Central Bank digital currency (CBDC) that would seek to compete with the wide domain of the stablcoins linked to the dollar, such as USDT and USDC. According to Financial Times, among the alternatives studied by the European Central Bank (ECB) as a technological basis They find networks like Ethereum and Solarium. According to the aforementioned source, the ECB evaluates «different technologies (both centralized and decentralized) in the development of the digital euro, including distributed registration technologies», although there is still no decision taken. In the event that the digital euro worked on a public chain (such as Ethereum or Solana), could be exchanged globally without frictionwhich would increase its circulation and use. However, European officials would have a cautious position in the face of that scenario: the public nature of transactions in networks such as Ethereum or Solana raises doubts about the privacy of users, a sensitive aspect for a CBDC. Criticism soon arrived. A person in X questioned the technical viability of the project: «They stop with false news. An EU stablecoin would need to handle more than 100,000 transactions per second to be viable. Neither Ethereum nor Solana could achieve it in their dreams. This comment reflects a background debate: while networks offer transparency and openness, their Current scalability limits they contrast with the demands of a monetary system of continental scope. At the time of this article, Solana has an average of 3,800 transactions per second (TPS) and the Ethereum ecosystem (L1 and L2), of around 300 TPS. While that user who in X exposed an amount of 100,000 referential TPS does not seem to be an authority in the ecosystem, it does make sense to think that a potentially used by an entire continent It will require a structure that supports a notorious amount of operations. In that context, current TPS in Ethereum and Solana They seem to place them far of the reference of 100,000 tps necessary «to be viable» in the digital euro project.
The reason behind the European trouble
The European hurry for this project would also respond to recent movements in the United States. After the approval of the so -called Genius Act, which gives a legal framework to the dollarized stablcoins, the EU began to «rethink plans for the digital euro.» European officials fear this regulation further drives the use of digital assets based on the US dollar. weakening the international position of the euro. A spokesman cited by the medium summed up the concern: «He is beginning to generate conversations that before the Genius Act did not exist.» For the ECB, the issue is not only technological, but strategic: to ensure that the common currency maintains its central role in the digital economy.
