Bitcoin and Ethereum face a 2029 quantum timetable as U.S. backs $300 million hardware push

CoinDesk reports that the quantum threat to crypto is not here yet, but the timelines are getting harder to ignore. Progress toward fault-tolerant quantum machines is starting to line up with the migration plans being discussed across the crypto sector, with both tracks converging on roughly the same 2029 window. That puts Bitcoin and Ethereum in a race against a clock that is becoming more concrete, even if the immediate risk has not arrived. The report also points to U.S. support for a $300 million hardware push. In that setting, the issue is no longer framed as a distant theoretical problem alone. Instead, it is becoming a scheduling challenge for major blockchain networks whose future security planning may need to keep pace with advances in quantum hardware.
