Muneeb Ali says Bitcoin has about two years to start its post-quantum upgrade

The Stacks co-founder used his Token2049 keynote to lay out a four-year window for upgrading Bitcoin and moving coins before quantum risks grow Bitcoin has a deadline problem, and Muneeb Ali wants everyone to start counting. Speaking at Token2049 Singapore on October 8, 2026, the Stacks co-founder said Bitcoin has roughly two years to upgrade, then about two more years to move coins before quantum computing risks intensify. Phase one is the upgrade itself: getting quantum-resistant signatures into Bitcoin. He put that window at approximately two years. Phase two is migration. Once the tools exist, holders still have to move their coins into addresses protected by the new signature schemes. Ali allotted about two additional years for that step.
