I think using KJV is good for enhancing the joke though.
Having >2/3rds of validators (or >50% of power in PoW) let's you rewrite the chain back in history, censor txs, etc. You control what transactions go in blocks, and to a certain extent also recent history.
HOWEVER, this does not give you the power to steal or rewrite state as you please. You cannot convince the rest of the network that you now own someone else's ETH just because you have supermajority validator power. To take away ETH or change the cabin state in any other way, you need to include a valid and correctly signed transaction.
If you include an invalid state change (not caused by a successful and correct transaction) then all other nodes will reject that block, no matter how much validator power or hashing work went into it.

This is both mean and unhelpful. And possibly a sign that they don't realize how bad they are at training a junior.
I realize I'm a total armchair advisor here and what the hell do I know. But reading how this person approached potential customers I kept thinking "oh man I wonder what will happen when he talks to the insurance companies, why would they not be interested?"
I like it. Part of a good proof is a rigorous derivation. There is plenty of thing sto be said about what intuition can lead us towards such a proof. But at the end of the day, a good proof is ideally almost machine-checkable. Most proofs (much like code) lives two lives: the one in which they are written, and the one in which they are read. It should be almost trivial for a student to go back, on their own, days or weeks later, and see that each step is valid. And I think prose interspersed between column-style proofs do a better job than what margin notes do. The reason two columns work well is that the step and it's justification are of both condensed and almost always of similar length. Justification (much like code comments) may or may not need a good chunk of space. And surely nothing is stopping anyone from inserting little margin notes here and there in a two-colum proof, right?
I'd say odds are that the website is wrong, but you can always load those keys in a wallet and see if they give you control over the actual address.
If that works, I'd assume it's the case that some people have used weak keys (for example, a popular Ethereum wallet would actually generate 256 bits of entropy but accidentally truncate it to 32 bits in an operation), and any funds in those wallets will have been snagged long ago.
Point being: generate a private key properly, and no one will ever find it.
EDIT: I realize this is another page then the one I've seen previously, but I think the same idea applies. That one had support for Ethereum, too, and on the final page was an account with a balance.
