Google Quantum Research suggests that future quantum computers may crack Bitcoin private keys in just 9 minutes

Research from the Google Quantum AI team indicates that, in the future, quantum computers may be able to derive private keys from Bitcoin public keys in approximately 9 minutes, allowing attackers to potentially hijack transactions before they are confirmed. About one third of all Bitcoin, including early coins and those held in addresses where public keys have been exposed or reused, could be easily stolen by powerful quantum computers. Although the core Bitcoin mining process would still function, the ability to derive private keys from public keys would undermine ownership security across the network. Currently, Bitcoin has not yet begun migrating to quantum-resistant cryptography, while Ethereum has already started the relevant transition.
