Well, people like me appreciate the analysis.
Then analyse this:
I added two numbers together to produce a result of 8.
Which two were they ?
(Clue: I mixed them - no cryptography involved, so should be easy for you
)It will be easy if I put a gun to your head and force you to tell me. Hence the masternode centralization concern.
The gun-to-the-head argument also applies to any coin, including Monero, in terms of giving up keys, access, or association to information.
But the difference is, if you hold up every Monero miner, due to blockchain anonymity, you still can't deanonymize the network's keyholders...I think.
