Google has released its quantum computer Willow, and the crypto community is once again asking the question: "Is this it for Bitcoin?" But, as it turns out, we can breathe easy for now. Willow has only 105 qubits, while millions are needed for a real threat. So Bitcoin is still stronger than your old password "123456".
Yes, quantum computers could theoretically affect mining and transaction signatures. But here's the interesting part: even a super-quantum computer with Grover's algorithm won't be able to instantly break hash functions. This is more like an upgrade to mining hardware than an apocalypse.
What about signatures? There are risks for old addresses and reused ones. So if you're still using the same wallet, it's time to think about SegWit. Developers are already discussing a transition to quantum-resistant technologies, so Bitcoin will adapt faster than many think.
And you know what? Quantum computers threaten not just crypto. Banks, communications, even your favorite messengers — everything is in the crosshairs. So Bitcoin is likely to survive, but I wouldn't envy your secure chat in social media.
What do you think?! And don't forget to subscribe before a quantum computer does it for you!
