Google Accelerates Quantum Threat Timeline, Sparks Bitcoin Security Concerns

Google has accelerated its efforts to prepare against the threat of quantum computing, setting a new target date of 2029 for securing its systems against future attacks. This warning has sparked renewed debate over whether Bitcoin could face security risks sooner than expected due to the potential impact of quantum computers on elliptic curve cryptography.

The tech giant's decision to bring forward its timeline is driven by rapid advances in quantum hardware, error correction, and cryptographic research. Google warned that some risks are already emerging, including 'store now, decrypt later' attacks, where attackers harvest encrypted data today expecting to decrypt it in the future.

To counter this threat, Google is prioritizing migration to post-quantum cryptography (PQC) for authentication systems. The company has urged other engineering teams to follow suit and has set a clear deadline to 'provide the clarity and urgency needed to accelerate digital transitions' industry-wide.
