#比特币挖矿难度创历史新高 #量化机器人

In the early morning of December 10th, Beijing time, Google launched its latest quantum chip "Willow" and claimed to have made significant achievements. People are worried that the chip may pose a threat to the security of cryptocurrencies: Bitcoin and other cryptocurrencies are mined by calculating complex mathematical problems to confirm transactions and record them on the blockchain. The demand for mining computing power is related to the number of "miners" in the network and the level of computing power. . Google's quantum chip "willow" has super computing power. In less than five minutes, it completed a "standard benchmark calculation" that the fastest computer today needs at least 10 to the 25th power of years to complete. If it is applied to mining, it will greatly improve mining efficiency, making it difficult for traditional mining machines to compete with it in terms of cost and efficiency; on the other hand, the security of cryptocurrencies depends on mathematical problems in cryptography, such as elliptic curve encryption and RSA encryption, which are based on the assumption that current computing power cannot be cracked within a reasonable time. Quantum computers can run quantum algorithms such as Shor's algorithm, which are specifically used to crack encryption technology based on large number decomposition. Once quantum chip technology develops to a sufficiently mature stage, its powerful computing power may crack the existing cryptocurrency encryption system, resulting in the leakage of users' private keys. In summary, these factors have affected investors' confidence and led to a market decline.
