Wouldn't a quantum computer need 256 qubits to break bitcoin?
Also, if there's a strange amount of blocks being mined by a new entity, can't we just fork with a new algorithm (and fuck over ASIC manufacturers at the same time

)
Where do you get that number from? Just curious.
Is not about blocks mined, is about keys broken. Full collapse, hard fork, market stop...
Sha256... I guess it'd be the entropy of the hash. I just assumed sha256 had 256 bits of entropy. That's probably a horrible assumption considering the 256 is the digest.
Honestly, I figured breaking mining would break bitcoin more effectively than hacking addresses.
