The European discussion on the digital euro seems to have gained momentum now that the United States has established a legal framework for stablecoins with the so-called Genius Act, leading Brussels and Frankfurt to reconsider whether a public blockchain such as Ethereum or Solana could be the carrier of a central bank currency. Although no decision has yet been made and the motivation remains primarily geopolitical and competitive in nature, namely preventing digital dollars from completely dominating the playing field.
Looking past the headlines, however, one can see that the preconditions are not yet in place, both formally and technically, as the ECB is still in the preparation process in which it is testing multiple technology options. While a final go can only come after Oct. 2025 and then only if European legislation is finalized, which means that talk of an implementation on a public network is now mostly hypothetical.
On the technical side, it immediately chafes at scale and reliability. Because as early as the second half of 2023, the euro zone's payment system processed over 71.2 billion non-cash transactions, which roughly translates to an average of over four thousand five hundred transactions per second over that period. While Ethereum remains at the base layer at around tens of transactions per second and thus can only scale up via intermediate layers, and while Solana claims high speeds, it arguably had to deal with network outages and resets multiple times, a central bank requiring zero tolerance for downtime is hard to accept.
Governance and jurisdiction also present tough obstacles, as a digital euro on a public network inherits the rules of the game and geopolitical friction of that network. This was evident in the U.S. sanctions against Tornado Cash where governments, regulators and judges clashed over what exactly to sanction on a decentralized system, the lesson being that external decisions can indeed affect transaction flows on a public network and that legal outcomes can slide for years, something that is an unacceptable uncertainty for monetary policy and financial stability.
The privacy issue on a public chain cannot be brushed away with technology marketing, as European privacy regulators have previously warned about data minimization, cyber risks and the need for explicit legal safeguards. While the ECB itself envisions privacy by design and even offline payments with cash-like confidentiality, which, on a public, indelible ledger, can only be reconciled with complex workarounds, such as value carriers that are later batch-settled, and strictly anonymized metadata, where any error immediately bumps up against the letter and spirit of the AVG.
On top of that, offline functionality does not fit well with a model that by default writes every transaction to a global ledger in real time, because guarantees for untraceable proximity payments require hardware security, local validation and delayed synchronization. Which points precisely toward a controlled, highly centralized infrastructure rather than a permissionless chain driven by anonymous validators.
Meanwhile, legal reality draws its own lines, because until the Digital-euro regulation is final, the Governing Council cannot decide on issuance. And the ECB continues technology agnostic testing rather than committing to a protocol whose performance, upgrade path and compliance are in constant flux, a sensible restraint given the crowded nature of the payments system and the demands for continuity, incident handling and accountability.
Of particular relevance to Suriname is that a digital euro will only have impact when it is stable, widely available and affordable to European banks and payment institutions with ties to the diaspora, because then remittances, trade and tourism can benefit from faster and possibly cheaper euro payments. Although the ECB currently indicates that use outside the euro area and the role of non-European parties are still under study, so immediate impact cannot be expected in the short term.
A digital euro on a public blockchain sounds like quick wins in adoption and interoperability, but wriggles at the points where central bank money should not wriggle, scale and uptime, legal control and privacy. And until that triangle closes and the law is in place, the fairest qualification is that the plan is politically understandable but technically and legally premature. With which, for now, the realistic route lies with a controlled, high-availability infrastructure with tightly configured privacy and offline modules rather than issuance on a chain that Europe does not control itself.
