While the achievement is significant, it is not a full fix for Bitcoin’s potential quantum problem. It is better understood as a demonstration that users can create a quantum-resistant escape hatch today, even while developers continue debating a permanent protocol-level solution.
Quantum computers pose a potentially serious problem for Bitcoin because much of the…
