No offense taken, and maybe the claim is excessive. But my claim is not about cryptocurrency per se but about blockchain technology. It may not turn out to be the case but I suspect that it - or something derived from it - will be very important in the future. That may have nothing to do with cryptocurrency at all.
My real point is, blockchain is just a subtle application of the maths that we already understood with cryptography in the first place. It's a
bloody clever bit of lateral thinking to have applied it as a web-of-trust-applicable model, absolutely - and I can easily sit down and ponder whether modern cryptography as a whole, or the Internet as it exists today, was the more impactful human invention.
It's just a shame that the incredibly interesting and powerful mathematics - yet again - doesn't gain any popular attention until people can monetize it. I guarantee that interest in blockchain would be very, very niche (as crypto stuff tended to be in the past) if it wasn't given the most roaring and impactful of demonstrations to those with no interest in the maths - a working demonstration that modern cryptographical methods are so mathematically friggin' tough, and the mathematics so complete in their theory, that it happily protects the entire concept of a monetary system and a currency within its bowels, and even with multi-millions up for grabs to someone that can defeat it... it just cannot be done. The only real attack against it, typically, is not against the maths, but blockchain being so minimal an application of the theory has a ridiculously small attack surface. It's an easy concept to grasp to visualise the magnitude of computing strength required to take over 50% of mining production. Far easier to swallow than just statistical theory, something which casinos and bookies actively rely on the average punter failing to understand at core.
Maths and applied maths are so incredibly interesting and harbour such power, but it can be sometimes nearly impossible to grasp the magnitude of the concepts the numbers tell you unless they are applied in such glorious demonstrations. Cryptographical security has cryptocurrency to demonstrate it publically (and way more sexily than simple identity proof and data security can, as the public doesn't appreciate either of these methods as they are just worked around rather than beaten.) And the next-to-infinite ability of a computer to simulate and make calculations is the working demonstration of Turing completeness theory.
I think this joke I stole from a friend, who stole from a friend, who stole from Twitter, makes the point as cutely as I ever heard:
'If you ever feel bad about making a 'nasty hack' in your program, just remember that a CPU is just a rock that we tricked into thinking. And in order to do that, we first had to make the rock flat, and fill it with lightning.'
