The institutions parking bonds, funds, and deposits on the chain are relying on precisely the guarantee that concentration puts at risk.
Key Takeaways
- Cambridge research places 31% of Ethereum node activity in the US and about 39% in the EU excluding the UK
- Node hosting clusters around three providers: Hetzner, AWS, and OVH
- Finalization stalls if more than 33.3% of validators drop offline simultaneously; a December 2025 client bug left the network under 9% from that line
- Ethereum L1 holds approximately $25 billion in tokenized real-world assets, more than any other public network, per ...
