Research from the Cambridge Centre for Alternative Finance indicates that 31% of Ethereum node activity is concentrated in the United States, making it the single largest country for Ethereum infrastructure by a significant margin.
What Cambridge Found About Ethereum Node Geography
The data comes from the Cambridge Blockchain Network Sustainability Index, a research initiative run by the University of Cambridge’s Judge Business School. The CBNSI Ethereum tracker monitors network-level data including the geographic distribution of node activity across the Ethereum blockchain.

According to the index’s network analytics dashboard, the US accounts for roughly 31% of Ethereum node activity. No other single country commands a comparable share, positioning the US as the dominant hub for Ethereum’s operational infrastructure.

Cambridge’s broader blockchain research has also examined Ethereum’s environmental footprint, particularly following the network’s transition from proof-of-work to proof-of-stake in September 2022. That shift dramatically reduced energy consumption but did not change the geographic pattern of node operators. For related coverage, see UK Crypto Donations Ban: Labour MPs Push Permanent Block.
Why US Node Concentration Matters for Ethereum
Nodes are the computers that validate transactions, store blockchain data, and enforce protocol rules. Their geographic spread is a core measure of how decentralized a network actually is in practice, not just in theory. For related coverage, see Bitcoin ETF Outflows Hit as Ether Fund Streak Ends.
A 31% share for one country means that US-based infrastructure, cloud providers, and internet service providers play an outsized role in keeping Ethereum operational. If US regulators imposed restrictions on node operation or if major US cloud regions experienced outages, a substantial portion of the network’s activity would be directly affected.
This concentration also carries regulatory implications. As US policymakers continue shaping crypto oversight, including decisions around Ethereum spot ETFs and digital asset classification, the fact that nearly a third of Ethereum’s node infrastructure sits within US jurisdiction gives regulators significant leverage over the network’s day-to-day operations.
It is worth distinguishing node activity from broader Ethereum adoption. Running a node requires technical resources and consistent uptime, which favors countries with mature cloud infrastructure and reliable internet. The US share reflects infrastructure capacity as much as community interest.
What This Means for the Ethereum Ecosystem
For market participants, the concentration data adds context to how Ethereum’s infrastructure risk profile should be assessed. A network where one-third of node activity falls under a single regulatory jurisdiction is meaningfully different from one with activity evenly spread across dozens of countries.
The finding also reinforces the US role in crypto infrastructure conversations more broadly. Institutions like Circle, which recently secured OCC approval for a national digital currency bank, and major staking providers are building within this same US infrastructure footprint.
For Ethereum developers and governance participants, the Cambridge data may prompt renewed discussion about geographic diversification strategies. Efforts to encourage node operation in underrepresented regions could help reduce single-jurisdiction risk over time.
Policy watchers in jurisdictions like the UK may also take note. As countries weigh their own crypto regulatory frameworks, understanding where blockchain infrastructure actually operates provides a more grounded basis for policy than token price alone.
