Can nodes in Etherium? Or is there a central governing body there which has the power to revert legitimate transactions, just like in traditional systems?
But hey, at least it's an unregulated, informal, ad-hoc process in Etherium with no justice system or oversight to enforce the rights of the little guy.
The DAO hard fork was an exceptional event that occurred in 2015, under very unique circumstances inherent to the world's first smart contract platform experiencing the world's first major smart contract hack, and has not been repeated since.
Ethereum at this point - with seven years of autonomous operation and no repeats of DAO-like hard forks - has proven to be an immutable and credibly neutral settlement layer.
