Will Quantum Computers Overthrow Bitcoin? Here’s the Explanation

Jakarta, Pintu News – Quantum computers are often cited as a threat to Bitcoin’s security, but experts say that this risk is still far in the future. Adam Back, CEO of Blockstream, insists that Bitcoin is still safe and that technological adaptations can be made before a real threat emerges.

The Beginning of Quantum Concerns

Concerns about the potential dangers of quantum computers to Bitcoin were raised again after Josh Otten, an author, claimed that future computers could open the earliest Bitcoin wallets.

Otten argues that this could threaten the security of coins owned by Satoshi Nakamoto, the creator of Bitcoin, and potentially shake investor confidence and collapse the price of Bitcoin. While this claim sounds alarming, many experts argue that Otten overlooked some important details and overestimated the capabilities of current quantum computers.

Bitcoin security is often misunderstood

Adam Back clarified that Bitcoin does not secure coins by locking data behind traditional encryption. Instead, Bitcoin uses digital signatures to prove ownership.

This is one of the reasons why early Bitcoin wallets are not easy targets. Public keys are only visible when coins are spent, and many early wallets, including those associated with Nakamoto, have never moved their funds.

Differences in Experts’ Opinions

Despite growing concerns, experts’ opinions on when quantum computers will be powerful enough to pose a real threat to Bitcoin vary. Vitalik Buterin, co-founder of Ethereum (ETH), acknowledges that the risk is real but measurable.

Meanwhile, Anatoly Yakovenko of Solana (SOL) predicts that powerful quantum computers may appear within the next decade. However, Adam Back has a more subdued view, estimating that a meaningful quantum threat might only occur in the next 20 to 40 years, if it happens at all.

Bitcoin Can Adapt Over Time

Bitcoin is not static; its network can evolve long before serious threats arise. Quantum-resistant cryptography already exists, and Bitcoin could adopt this technology if needed.

Bitcoin analyst Willy Woo adds that even in the worst-case scenario, the network will not crash. He believes that the sharp price drop will attract strong buying from long-term holders, which will result in a long period of adjustment, not the end of Bitcoin.

Conclusion

For now, most experts agree that quantum panics often make more news than they actually do. The Bitcoin network has been designed to be adaptive and resilient to various threats, including the potential of future quantum computers.
