private keys stored at the Royal Mint in London!
Does this also consider as 'Decentralized'? Because you still don't own your private keys.
Because even it's not entity will store their private keys into that building, they can't still control their wallet since there are some people holding their private keys.
For example, I have my Ethereum wallet and I will store my private keys to that building, how can I sure that no one will know my private keys? Because in the first place, I have given some people my permission to get and use my private keys. That's a pretty hard decision, but still, don't know how it works when you store your private keys there, like what are the consequences how to get your private keys or how other people can retrieve the private keys on behalf of you.
