Bitcoin Faces Quantum Threat Beyond Wallet Keys
- Andrew Gault, CEO of ZeroTier, warns that the real risk lies in encrypted data moving between financial institutions.
- Citi estimates a quantum-enabled attack on a major U.S. bank could trigger a $2 trillion to $3.3 trillion economic cascade.
- Google aims to complete its post-quantum cryptography migration by 2029, focusing on authentication and digital signatures.
- The probability of a relevant quantum computer arriving by 2034 is estimated at between 19% and 34% according to the Global Risk Institute.
- Ethereum has initiated a post-quantum migration plan, while Bitcoin has not made similar commitments.
Gault emphasizes that adversaries are currently collecting sensitive authentication records for future decryption as quantum capabilities advance. This “harvest now, decrypt later” strategy poses significant risks to both Bitcoin and the broader financial ecosystem.
With over $2 trillion at stake from potential quantum attacks, the urgency for robust security measures in cryptocurrency transactions is critical as Ethereum moves forward while Bitcoin remains unprepared.(Source)
