Sir if encryption is cracked bitcoin is the least of my worries
Discussion
i heard this line touted a lot but it's a wholly unimpressive argument. most systems are trivial to upgrade to higher and higher keysizes way faster than how q computers can progress. and they almost immediately gain the security benefits of such upgrade without a long migration period that can never be truly completed.
You telling me you have faith in cybersecurity practices around the world and this is in the case its out in the open if qc was done in stealth than what the arguement bitcoin to not be the target in case of encryption being broken makes perfect sense to me
If you're talking about cracking the computation of private keys from public keys, you'd still have to add entropy to your private key and move your coins to a new address.
But I think the OP meant cracking mining, which is what uses sha256. The private key to public key function uses elliptic curves and sha256 (twice).
