#BTC🔥🔥🔥🔥🔥 Part 2: How long will it take before even Bitcoin, with its robust security, becomes vulnerable?

An RSA key falls to a quantum computer

Professor Wang Chao from Shanghai University and his team published a study in the Chinese Journal of Computers detailing how they decrypted a 90-bit RSA key. The most shocking aspect is not just the achievement, but the tool: they used a D-Wave Advantage quantum computer, which has 5,760 qubits and is commercially available.

This computer achieved what was unthinkable for a conventional computer in a reasonable time: factoring huge numbers, the basis of RSA encryption, thanks to a process called quantum annealing. This method leverages phenomena such as entanglement and quantum superposition to optimize calculations and solve mathematically complex problems.

The beginning of the end for cybersecurity?

Although Bitcoin uses a different system than RSA, called ECDSA (based on elliptic curves), the Chinese experiment raises alarms. If an RSA key is already vulnerable with accessible quantum technology, it is only a matter of time before other encryption systems become vulnerable as well.

The fact that the D-Wave Advantage is not an experimental and ultra-secret device, but rather a platform accessible to certain institutions, makes us question the security of our cryptocurrency wallets, bank accounts, and even the data networks we currently consider impenetrable.

A silent threat advancing

For now, Bitcoin's algorithm remains secure. But the pace at which quantum computing is advancing suggests that digital immunity will not last forever. This warning is not just for cryptocurrency enthusiasts but for all infrastructure that relies on traditional cryptography: no system is safe from the emerging power of qubits.

Did you think digital security was unbreakable? This advancement shows us that reality surpasses fiction.
