Recently, discussions about the impact of Quantum Computers on Bitcoin have once again captured public attention. Some even predict that Bitcoin will drop to zero by 2035, which inevitably brings to mind those who once predicted the end of the world in 2012. However, is there really any basis for such claims? Let’s delve deeper into this issue.

The potential impact of Quantum Computers on Bitcoin is primarily reflected in its consensus mechanism. Bitcoin currently employs a Proof of Work (PoW) mechanism, which simply means competing for the right to record transactions through computational power. Theoretically, if a node possesses more than 50% of the network's computing power, it could carry out what is known as a '51% attack', altering transaction records.

So, will Quantum Computers cause this situation to occur? The possibility does exist, but it requires one important premise: a node using a Quantum Computer must occupy more than 50% of the total network computing power. However, the likelihood of this situation occurring in reality is extremely low.

First of all, based on existing information, Quantum Computers do not provide exponential improvements in calculating hash values. This means that a single quantum computer node cannot easily surpass the total of traditional computer nodes. Secondly, with the development of technology, Quantum Computers are likely to be widely used in the Bitcoin network, rather than being monopolized by a few individuals.

More importantly, the Bitcoin network has the capability to address potential security threats through consensus. If Quantum Computing indeed poses a threat to the network, the Bitcoin community can enhance security through protocol upgrades, such as adopting quantum-resistant algorithms.

Therefore, while the development of Quantum Computing may indeed have some impact on Bitcoin, asserting that it will lead to Bitcoin 'drop to zero' is overly presumptuous. The security and adaptability of the Bitcoin network should not be underestimated. As technology advances, we may see Bitcoin and other cryptocurrencies demonstrating greater resilience and innovation when facing new challenges.
