What happens if 1-way functions no longer exist? Advances in AI and nanobiotech  can radically increase intelligence to the point where unsolved mathematical problems get solved.

What happens to Bitcoin (and other cryptocurrencies) if &pointint;&thinsp;1-way functions cease to exist?
without modifications the current bitcoin system would simply be compromised.

it seems very likely all private-public key cryptography would be compromised as well, and society as we know it would change.

however, given unknown advances to begin with, there is always the chance that something entirely different could replace the current system of secrecy when it comes to trust.

there is also the possibity that no matter how many advances we get, 1-way functions might be impossible to completely break, or that we find new maths that guarantees breakage if any 1-way function but with a cost that is prohibitive.
