Ethereum appears at risk of getting kicked off the cloud-networking provider that powers roughly 10% of the second-biggest blockchain.

If Ethereum is forced off Hetzner, it would further whittle down where it resides, raising the question of just how decentralized the purportedly decentralized blockchain really is. According to ethernodes.org, over 60% of Ethereum nodes – the computers that process transactions on the network – are hosted by cloud service providers. Of these cloud-hosted Ethereum nodes, Hetzner powers roughly 16%, second only to Amazon Web Services at around 53%.
Hetzner didn’t respond to a request for comment from CoinDesk by press time.
It is unclear how long the ban has been in place or whether the firm has ever taken action to enforce it. “We are aware that there are many Ethereum users currently at Hetzner, and we have been internally discussing how we can best address this issue,” Hetzner said in its post.
The statement from Hetzner comes on the heels of recent U.S. Treasury Department sanctions on cryptocurrency addresses related to Tornado Cash, an Ethereum-based utility that allows users to send and receive funds without leaving a clear trail.
The Tornado Cash situation sparked debate in the Ethereum community around whether nodes operating the network – or the infrastructure powering them – might be forced to censor transactions or otherwise curtail activity in accordance with the sanctions.
This debate will only amplify next month when Ethereum transitions to proof-of-stake, a more energy-efficient system for processing transactions that has sparked its own centralization concerns.
