"Quantum Doomsday" arriving early? Project Eleven warns: "Q-Day" could strike as soon as 2030

With the development of quantum computing technology, the "doomsday threat" facing the cryptocurrency world may arrive sooner than expected. Project Eleven, a development company focused on post-quantum cryptography, predicts that the critical point when quantum computers break modern encryption—commonly known in the tech world as "Q-Day"—could arrive as early as 2030. A report by Project Eleven indicates that the probability of "Q-Day" arriving before 2033 is "over 50%," with a margin of error of only a few years. Quantum technology will experience "leapfrog" explosions. It is worth noting that Project Eleven assesses that the progress of quantum technology will not be a smooth, linear development, but rather a series of leapfrog breakthroughs. Advances in hardware and algorithms are compounding, which could eventually trigger a massive leap in capabilities. The company describes this process in one sentence: "First silence, then a sudden explosion." Recent scientific evidence seems to silently support this theory. Just last month, researchers successfully used quantum hardware to derive a 15-bit elliptic curve key. While this achievement is noteworthy, there is still a long way to go before cracking the 256-bit encryption commonly used by cryptocurrencies like Bitcoin. According to Project Eleven's estimates, under certain conditions, approximately 6.9 million Bitcoin (valued at over $560 billion) could be exposed to quantum risks. The Great Security Migration: A race against time for survival. Even if, as researchers suggest, there are still a few years before "Q-Day" fully erupts, guiding global users to migrate their assets on a large scale to "quantum-resistant" secure wallets and addresses will also take a long time. The report specifically cites the famous "Mosca’s inequality" theory in the field of cryptography as a warning: In short, if the time required to upgrade a system is longer than the time it takes for the threat to arrive, then we are already behind. This intense sense of crisis is driving the cryptocurrency industry to launch self-rescue operations in advance. For example, Dan Robinson, a researcher at the top crypto venture capital firm Paradigm, recently proposed a concept: allowing Bitcoin holders to prove wallet ownership now via a "Timestamp." In the future, once Bitcoin upgrades to a quantum-resistant version, users could redeem their funds without exposing their existing on-chain transaction history. On the other hand, "BIP-361," co-proposed by veteran developer Jameson Lopp and others, advocates for a multi-year "transition period," giving users sufficient time to safely transfer funds to new addresses with quantum-resistant capabilities. Of course, in the face of the threat of quantum supremacy, no one can stay out of it; it is not just the cryptocurrency industry that is vulnerable. Traditional tech giants, including Google, are also moving up their defense deadlines, aiming to complete the system-wide migration to post-quantum cryptography by 2029.
