Just now, I read a quite interesting analysis from Shaw, the founder of ElizaOS, about a concern many people are worried about – the threat of quantum computing to Bitcoin.

In fact, Shaw pointed out that this worry mainly stems from a misunderstanding of the current technology's actual capabilities. Specifically, when it comes to Grover's algorithm, people often forget that it only reduces the search space of SHA-256 from 2²⁵⁶ to 2¹²⁸. This number is still large enough to ensure Bitcoin's security for a long time.

As Shaw explains, although Shor's algorithm could theoretically threaten RSA/ECDSA, it requires complex preprocessing steps and has not yet been implemented at a large scale. Moreover, to truly break Bitcoin with quantum technology, you would need to perform the attack quickly, which would expose all encrypted data – a scenario that is still purely hypothetical at this point.

What Shaw wants to emphasize is that spreading fear about quantum computing is mainly due to misunderstanding. This technology is still far from becoming a real threat to Bitcoin's current encryption systems. Instead of panicking, we should approach the issue logically and based on actual technical data.
