The Ethereum network continues to evolve, but its geographical distribution remains a subject of monitoring for researchers. A new study from the Cambridge Center for Alternative Finance shows that a significant share of nodes operates in North America and Europe. This snapshot of the network highlights several technical and legal issues. It also reminds us that the location of infrastructures can influence the protocol’s resilience. The updated data finally sheds new light on the network’s energy consumption after the merge.
In brief
- 31% of Ethereum nodes are hosted in the United States, compared to 39% in the European Union excluding the United Kingdom.
- The network can stop finalizing its transactions if more than a third of validators become simultaneously inactive.
- The concentration of infrastructures and client software remains a major issue for Ethereum’s resilience and decentralization.
- Ethereum’s energy consumption has dropped by about 99.98% since the merge, according to the new Cambridge study.
Ethereum’s Geographic Distribution Is Dominated by the United States and Europe
The new study indicates that 31% of Ethereum activity is now hosted in the United States. The European Union, excluding the United Kingdom, concentrates about 39% of this activity. In a statement attributed to the daily show The Starting Block, Alexander Neumuller, head of research at the Cambridge Center for Alternative Finance, estimates that the distribution remains heavily oriented towards Western countries. However, it does not indicate excessive concentration in a single state.
Researchers also observe that nodes rely heavily on three major hosting providers: Hetzner, AWS, and OVH. Alexander Neumuller recalls that Hetzner’s terms of use previously prohibited operating blockchain services. However, he notes that this policy may have evolved. This concentration of infrastructures therefore deserves ongoing attention, even if the data do not show a unique national imbalance.
The study also emphasizes that the relationship between nodes and validators remains difficult to measure precisely. The same access point can indeed host several validators. Researchers explain that it is therefore impossible to know exactly the number of validators associated with each infrastructure.

The analysis conclusions remind us of an important characteristic of Ethereum’s operation. Contrary to some misconceptions, the network does not need to lose half of its validators to encounter a problem. As soon as more than a third of validators simultaneously cease their activity, checkpoint finalization may be interrupted.
This situation explains why the distribution of Ethereum nodes represents a strategic element for the network’s stability. An interruption affecting a widely used infrastructure could slow down overall operation. However, Alexander Neumuller specifies that the available data do not allow a direct link to be established between each node and the exact number of validators it hosts.
Concentration concerns not only physical infrastructures. According to the researcher, client software diversity also plays a crucial role. A technical defect affecting a dominant client could quickly spread to a large part of the network. The report thus presents detailed data on the distribution of consensus clients and execution clients to illustrate this other risk factor.
A New Energy Estimate and Ongoing Legal Challenges
The location of nodes goes beyond the simple technical framework. In 2022, the United States Securities and Exchange Commission (SEC) estimated that it could claim jurisdiction over Ethereum. The authority notably relied on the fact that a majority of the network’s infrastructure was then hosted on U.S. soil. This issue therefore continues to fuel reflections on the legal framework applicable to transactions.
Alexander Neumüller nonetheless presents the current geographical distribution as a balance he considers positive, while specifying that it is his personal assessment. According to him, better geographical distribution is an advantage for a decentralized network.
Geographical distribution is a real asset for the network’s resilience, even if the community must continue to monitor its evolution. At the same time, a strong concentration of client software could amplify the consequences of a bug affecting the most used client.

He also believes that a strong concentration of client software risks quickly spreading the effects of a bug affecting the network’s main client. On this, the community must continue to closely follow this development.
The report also updates Ethereum’s energy estimates thanks to a new methodology. Researchers now use empirical data on node distribution between residential and commercial hosting, rather than theoretical assumptions. This approach takes into account software changes made after the merge, which can modify equipment consumption.
The new estimates assess the annual network consumption at about 7.9 gigawatt hours, equivalent to a continuous power of one megawatt. This corresponds to the consumption of about 2,000 British households. The study also estimates that this consumption remains about 99.98% lower than levels observed before the merge. Finally, the share of sustainable energy used by the network now exceeds 56%, compared to an estimated global average of 43%.
Researchers also estimate the theoretical cost of fully offsetting annual emissions through high-quality carbon credits. This would be between 25,000 and 55,000 pounds sterling, an amount Alexander Neumuller compares to the price of a car. He indicates that this estimate is the result that surprised him most. The Ethereum Foundation supported this study, while researchers specify that their analyses on decentralization reflect their own interpretation. Upcoming observations will measure whether this geographical distribution continues to evolve while preserving network resilience.
