It is my understanding that in proof of stake, the validator puts up a stake that gets slashed if they don't respond to requests truthfully. In the scenario that someone hacks into your node, wouldn't it be very easy to slash someones funds and have them lose a ton of money?
The scenario I am trying to capture here is one where you try to run a proof of stake validator on the cloud or an environment that could be more prone to breaches. In PoW, it would be inefficient, but, I could run a miner on my cloud and just give it the public key. It'll continue making me money without the private keys. If I want to run my own wallet to interact with my account I could setup a node in a more locked down environment to accomplish that and on an on-demand basis. For PoS I would assume it would be risker to try this since the validator would need to have access to the private key or some hypothetical staking key that provides lesser access.
Does Ethereum have any protections from this?
