Bitcoin Wallets Vulnerable to Quantum Attacks, Study Finds

A groundbreaking study released by Google's Quantum AI team has raised concerns about the security of Bitcoin wallets. The research suggests that advanced quantum computers could compromise the cryptographic foundations securing Bitcoin transactions.

The study found that powerful quantum machines could extract private keys from public keys in approximately 9 minutes, creating a significant vulnerability. This is because Bitcoin's transaction architecture necessarily reveals the public key to the network during each transaction.

However, a more pressing danger exists on the blockchain itself. Research suggests that roughly 6.9 million Bitcoin - representing about one-third of total supply - reside in addresses where public keys remain permanently exposed. These holdings face heightened vulnerability because attackers wouldn't face time constraints.
