Linux is of course very impressive and most Ethereum nodes run on Linux. But you can peg a machine to a specific version of Linux and never have to upgrade if you desire. Your machine is ultimately independent of other Linux machines. The key challenge with a blockchain is that you have to keep what amounts to a globally distributed and permissionless data center in sync with protocol upgrades and the cost of making a critical mistake can be in the billions of dollars. You have to account for not just technical vulnerabilities but game theory vulnerabilities.

The challenges are of course, entirely different in OS kernel land. All of them are impressive.
