Quantum threat to Bitcoin looms as researchers slash attack benchmarks

Google’s quantum milestones just got a reality check. Researchers have successfully halved the resource benchmark required for the specific operations needed to crack Bitcoin and Ethereum encryption. While earlier estimates from the tech giant suggested a massive hardware hurdle, this new calculation proves the finish line is closer than previously feared. The team slashed the necessary qubit count by over 50%, though they admit their accounting method differs slightly from Google’s baseline. It’s a mathematical shortcut that makes the 'quantum apocalypse' scenario feel less like sci-fi and more like a looming deadline for core developers. If the hardware catches up to these optimized algorithms, the current cryptographic walls protecting billions in digital assets won't hold. Will the industry migrate to post-quantum signatures before the hardware finally bridges this shrinking gap?
