Bitcoin has been perceived for years as a fortress built on cryptography that cannot be cracked in practice. However, a new quantum experiment reminds us that even the strongest technological foundations may come under pressure over time. This is not an immediate threat, but rather a warning signal that the crypto world should start addressing its post-quantum future before it’s too late.<\/strong><\/p>\n\n\n\n

Small Key, Big Debate<\/h2>\n\n\n\n

Researcher Giancarlo Lelli managed to crack a simplified 15-bit key based on elliptic curve cryptography using a quantum computer. This type of cryptography, in a much more advanced form, also protects bitcoin<\/a>. The experiment used a modified version of Shor’s algorithm, which has long been considered one of the main reasons why quantum computers could one day change the rules of digital security.<\/p>\n\n\n\n

It’s important to note that bitcoin works with 256-bit keys, so the difference between a laboratory experiment and a real attack is still enormous. Nevertheless, the demonstration is significant: it shows the direction of development and reminds us that the barrier between theory and practice may gradually shrink. The cryptocurrency<\/a> sector is therefore not addressing the question of whether bitcoin is threatened today, but whether it will be ready when quantum computing power advances several critical levels further.<\/p>\n\n\n\n

Older Addresses Are Most Vulnerable<\/h2>\n\n\n\n

The greatest attention is focused on older bitcoin addresses where public keys have already been revealed. This is where there could be room for attack in the future if a sufficiently powerful quantum computer capable of reverse-calculating the private key were to emerge. Estimates speak of hundreds of billions of dollars in BTC that could theoretically be exposed to risk, although today’s technology<\/a> does not yet allow such an attack.<\/p>\n\n\n\n

The real risk is therefore not that quantum computers will crack bitcoin tomorrow. The risk lies in the slow preparation of the ecosystem. If development accelerates, it will be necessary to address new signature methods, migration of older addresses, and a broader transition to post-quantum cryptography. This is why tech players like Google<\/a> are increasingly joining the debate, as their research could significantly influence the pace of the entire quantum era.<\/p>\n\n\n\n
