Part 3/10:
- Short-range attacks: These occur during the brief window when a Bitcoin transaction remains unconfirmed in the mempool (lasting from five minutes to potentially an hour). During this time, a sufficiently powerful quantum computer could potentially derive your private key from your exposed public key, enabling an attacker to steal coins before the transaction confirms. However, these attacks are less immediate because current quantum computers are not yet capable of operating at such speeds and power.
