Early Bitcoin contributor Adam Back has pushed back against warnings that quantum computers will destroy Bitcoin, pointing out that relevant protection algorithms are already in the protocol planning phase. Previously, StarkWare CEO Eli Ben-Sasson warned that without implementing quantum fixes, Bitcoin would lose its leadership position due to the physical limitations of computing systems. Back stated that the quantum threat has been exaggerated, noting that hash functions are immune to Shor's algorithm, the brute-force acceleration brought by Grover's algorithm can also be neutralized by Bitcoin's standard security settings, and the community is advancing technical solutions such as hash-based signature protocols (e.g., SHRINCS).
