Quantum researchers slash timeline for Bitcoin and Ethereum hack risk

Quantum researchers slash timeline for Bitcoin and Ethereum hack risk

The clock just started ticking faster for Satoshi's code. A new research paper reveals that a tag-team of human experts and AI agents managed to crush Google’s March benchmarks for a specific math problem used in Shor’s algorithm. This calculation is the master key required to break the cryptography guarding Bitcoin and Ethereum wallets. By optimizing the core logic, the team effectively halved previous estimates for when a quantum computer could brute-force top-tier private keys. The breakthrough doesn't mean your stash is gone tomorrow, but it proves the hardware requirements for a successful attack are shrinking faster than developers anticipated. Most experts previously banked on a decade of safety, yet this new data suggests the window for a 'quantum-resistant' upgrade is closing. Will the industry migrate to new signatures before the first trillion-dollar hack, or are we just watching a slow-motion car crash?
