7 sats \ 2 replies \ @000w2 10 Dec \ on: Tuesday Survey: Is Quantum a Threat to Bitcoin? bitcoin
For those people voting "No"/"Bitcoin doesn't care", do you want to explain why? In principal bitcoin's cryptographic primitives are broken by a quantum computer.
Are you saying quantum computers that can do useful calculations are not possible?

advanced quantum computers might theoretically be able to derive private keys from public keys in the mempool before miners confirm transactions, (still wondering if it is even possible), the real question is: would it be worth it? The energy costs would be enormous, making it economically unfeasible. I believe there's an important distinction between what's technically possible and what's likely to actually happen in practice.

Pay to public key coins, pay to taproot coins and reused addresses wouldn't need to be in the mempool.
And a 10,000 coin utxo is ~$1B today. Breaking one of those keys and also buying a bunch of put options could make it worth the cost.
