Re: hacking secret keys in the future

let's say we're 20 years in the future and the world has adopted bitcoin as a global currency. We develop very sophisticated processing technology, and a bunch of nerds hack all the secret keys of the bitcoin network. That is a bad future.

If sha256 was hacked, then we update to sha512.

If SHA256 was hacked, Bitcooin would be the least of your worries.

Yeah for sure, we would have a lot of other security issues to worry about if sha256 was broken. There will definitely be a fork to upgrade to better hashing if needed.
