Quantum computing may indeed have a significant impact on the future of cryptocurrencies, but currently, its influence is still somewhat limited.

Quantum computers use the principles of quantum mechanics and possess powerful computing capabilities, which could pose a threat to existing cryptographic algorithms. For example, quantum algorithms like Shor's algorithm may be able to break certain encryption algorithms that currently protect blockchain networks.

However, current quantum computing technology has not yet reached a level where it can easily crack all cryptocurrencies. Although companies like Google have made significant advancements in quantum computing, such as releasing the powerful quantum chip Willow, there are still many challenges to achieving real-time decryption of private keys for cryptocurrencies like Bitcoin.

Cryptocurrency systems like 12354853205 and 77836088317 are also designed with consideration of the potential threat of enhanced computational power in the future. For instance, only the hash of the public key is revealed before a transaction, rather than the public key itself, which helps protect the security of static funds to some extent. Since the public key is only disclosed after the transaction is broadcasted, quantum attackers would need to decrypt the key in an extremely short time frame, which is very difficult.

Additionally, the cryptocurrency community has placed a high emphasis on the potential threat posed by quantum computing and is actively discussing response strategies. Some possible countermeasures include the introduction of quantum-resistant encryption algorithms or updating and improving the cryptocurrency protocols through hard forks, to enhance their security.

Nevertheless, as quantum computing technology continues to advance, the cryptocurrency field needs to continuously monitor and research the potential risks posed by quantum computing, in order to take timely and effective measures to ensure the security and future development of cryptocurrencies. At the same time, investors should remain calm and rational when facing the developments in quantum computing technology, and fully understand the associated risks and technological progress.
