Quantum Attack on Crypto Threatens Stealthy Breaches and Catastrophic Consequences

Experts warn that a quantum computer attack on the cryptocurrency market could arrive without warning, leaving little to no technical evidence of how funds were stolen.

Christopher Smith, CEO and co-founder of Quantus Network, says that a sufficiently powerful quantum computer can derive private keys directly from public keys visible on blockchains, bypassing the need to compromise exchanges, hardware wallets, or individual devices.

This method leaves no conventional evidence of a hack, making it difficult for investigators to determine how funds were stolen. Smith notes that in a highly secure organization, 'the only forensic evidence would be that there was no breach.'

The threat extends across virtually the entire digital asset market, with an estimated 99.96% of crypto assets remaining vulnerable to quantum attacks, representing approximately $2.3 trillion in value.
