I wonder what IS crypto currency in some practical sense?
Would you sort of get paid by being given some string of numbers, and then.. when trying to pay with that string of data, the string data is hashed and then it is determined if the string data has value and maybe that data can be altered to be adjusted up or down?
Somehow, I just do not trust cryptography given the terrible state of computer security and the lack of privacy. I actually wrote a wall of text here about my naive thoughts about crypto currency, but I realized I actually have no good idea of how it works, so I deleted my initial text. I could say stuff referencing stuff from cryptography, but I can't connect the dots to show how cryptography works together with how crypto currency works. Would 'fully homomorphic encryption' be a part of future crypto currency?
Wild speculation, knowing nothing about crypto currency (because doing that is fun):
I can't help but wonder if maybe crypto currency could be said to be a hash system that sort of works like security by obscurity, in the sense of trusting data strings to hash as expected within a short time, but then, if you just hash them further, you could reveal even more data, as if the data strings could be backdoored that way.
I am curious to learn more about a vague question of mine: what a future "society" would be, if "society" was then being 100% dependent on using crypto currency? Would everything be just dandy, or could it be the proverbial police state? (If it really turns out that *somehow* crypto currency is just a means to control, but isn't really secure.) Maybe some money could have more privacy than others, being more difficult to hash, and then others would have less privacy, being easy to hash for meta tags as per design, as I wildly imagine for fun.
I can also vaguely imagine future crypto currency in the future existing as some kind of ephemeral string of numbers that are all controlled by some over arching crypto scheme (imagine ephermeral Diffie Hellman crypto for one time use (ideally)), as if, the data strings sat in a huge compartmentalized computer that ran 24/7, simply recreating data strings all day long, all year, as if, so to speak, re-print physical money to create this new design on paper money, to control who gets to use this money.
