Quantum computing and Blockchain [] QC attacks []. The most dangerous attack by quantum computers is against public-key cryptography. On traditional computers, it takes on the order of 2 128 basic operations to get the Bitcoin private key associated with a Bitcoin public key. This number is so massively large that any attack using traditional computers is completely impractical.
