Shor's algorithm can be used for solving the discrete logarithm problem significantly faster (digital signing), but the miners are safe, so only a soft fork is needed. Work is on the way to standardize a quantum-safe digital signature, but it takes years to get the best solution, and right now there's no time pressure.
