A groundbreaking technical alternative that can block quantum computer attacks without a network upgrade has been proposed, drawing significant interest from the industry.
According to Cointelegraph, a cryptocurrency specialized media outlet, on April 10 (local time), Avihu Levy, Chief Product Officer of StarkWare, an Israeli blockchain technology company, proposed a Quantum Safe Bitcoin (QSB) transaction method that can ensure quantum security without modifying the Bitcoin (BTC) protocol. Levy emphasized that this proposal "can maintain security even against attackers with large-scale quantum computers running Shor's algorithm." The core of this research is that it functions perfectly within existing script constraints without core rule modifications like a soft fork.
The principle of the QSB method is based on technology that replaces the existing signature verification method with a hash-to-sig puzzle. Instead of elliptic curve mathematical models that quantum computers can easily break, this method induces the sender to repeatedly perform computations until a specific hash result matches a valid Elliptic Curve Digital Signature Algorithm (ECDSA) signature. This structure makes it impossible to shorten the computation process even with quantum computers, thus providing strong quantum resistance to the Bitcoin network.
Eli Ben-Sasson, CEO of StarkWare, commented on the research achievement, stating, "This is a very significant development, meaning that Bitcoin can become quantum-safe as early as today." While the Bitcoin community has been debating long-term upgrade directions to counter quantum threats, QSB presents a practical and immediately applicable alternative. This is considered a very practical approach, especially given Bitcoin's unique characteristics, where the social consensus process for protocol modifications is complex and time-consuming.
However, due to high computational costs and technical complexity, the QSB method is expected to be utilized as a specialized tool for protecting large assets rather than for everyday small transactions. According to Levy's analysis, a sender would have to pay $75 to $150 in GPU computation costs for a single transaction. Furthermore, there is a limitation that the data structure is more complex than a typical Bitcoin transaction, which may cause a slight delay in processing speed. However, for whale investors for whom security is absolutely paramount, the value of asset protection far outweighs the cost, making it a sufficiently viable option for adoption.
Amid varying predictions regarding the commercialization timeline of quantum computers, this research has demonstrated that the Bitcoin ecosystem can flexibly respond to external threats through technological advancement. While a post-quantum cryptography upgrade for the entire Bitcoin network will be necessary in the long run, innovative proposals like QSB are expected to serve as a powerful shield during the transitional phase. The virtual asset market is expected to dispel security concerns and further enhance its reliability as digital gold.
