BlockBeats News, December 31 — ElizaOS founder Shaw shared his views on “Quantum Computing Threat to Bitcoin.” Its realization is much farther off than current media reports suggest. For hash functions like SHA-256, Grover’s algorithm only reduces the search space from 2²⁵⁶ to 2¹²⁸, but 2¹²⁸ remains unbreakable. Shor’s algorithm can theoretically crack RSA/ECDSA encryption, but current quantum computers typically rely on preprocessing or known factors for optimization, and are not pure Shor algorithm implementations. To crack Bitcoin, a real-time network, it would require rapid repeated execution. If feasible, all encrypted data would be exposed, and Bitcoin would then be a minor issue. Modern cryptography has always assumed future computational growth; quadratic acceleration was anticipated and considered decades ago. Whenever you see fear or hype around quantum computing, remember: these people know nothing at all.
