mathematicians: "haha, look at this -- based on what we know about math right now, there's no way to make certain operations easily reversible."

computer nerds: "cool, we can use this to encrypt data in transit."

mathematicians: "nice. Though don't bet on it always being hard. I mean, we solve hard problems all the time, haha."

cryptocoin nerds: "In fact, we're going to bet trillions of dollars on it remaining hard forever."

@tomosaigon @rysiek if RSA is broken tomorrow, it's going to be painful, but straightforward for everyone using TLS to move to quantum-resistant protocols. All previously captured transactions will be suspect for sure, but very few entities in the world would be in a position to decrypt them.

Blockchains, on the other hand, depend entirely on the chosen PKI algorithm to remain unbroken, otherwise any transaction on the chain can be faked.

At least now you'll have a chance to learn when someone breaks RSA^W ECDSA.

If there weren't trillions on dollars sitting on it, whoever broke ECDSA would likely keep it to themselves, silently and very selectively faking signatures or MITMing their targets.
