Regarding the issue of quantum decryption of encrypted networks, how should I put it? It's like how previously a complete gaming console was needed to run Contra, but now a small program can run it perfectly. This is an inevitable development of the times. The key issue is not about decrypting encrypted networks, but rather, why decrypt encrypted networks? Why not decrypt traditional financial system networks? Compared to the funds in traditional financial networks, the amount of cryptocurrency is negligible. Why pick sesame seeds when there are watermelons to harvest? Additionally, quantum computing will have corresponding quantum cross-chain areas, with both two-dimensional and three-dimensional representations.

Since the event last month when the United States confiscated 127,000 Bitcoins from Chen Zhi, discussions about Bitcoin no longer being secure have become rampant. For a moment, it was hard to tell whether there were really that many fools or if it was just the incompetence of those who missed out.
This case has recently revealed new details, clarifying why Chen Zhi's Bitcoins were stolen.
In technical terms, it is because Bitcoin uses asymmetric encryption technology. The Bitcoin private key is a string of 256-bit binary random numbers, with a theoretical number of attempts to crack it being 2^256 times, which is nearly impossible.

However, if this 256-bit binary private key is not completely randomly generated, for example, if 224 bits follow a specific pattern that can be deduced, and only 32 bits are randomly generated, it would significantly reduce the strength of the private key, requiring only 2^32 (approximately 4.29 billion) attempts to crack it through brute force.
