# Will Quantum Computing End Bitcoin?

## Summary

This video addresses the panic surrounding a recent study suggesting that breaking Bitcoin's cryptography could require significantly fewer quantum resources than previously estimated. The speaker argues that while the headline numbers are alarming, the real threat is not quantum physics itself but the fear and misinformation spreading across the internet. The video emphasizes that the same cryptographic protections apply to all digital systems, and that Bitcoin would be the last thing to be attacked if quantum computers became a real threat.

### Key Points

- **Surprising Study on Quantum Resources** [00:01] — A study published recently claims that breaking Bitcoin's cryptography would require about 20 times fewer resources than previously thought, reducing the estimate from millions of qubits to less than half a million qubits.
- **Internet Panic and Noise** [00:15] — The news triggers widespread panic, with many online voices urging people to sell their Bitcoin immediately, claiming it's over. The speaker advises focusing on the signal rather than the noise.
- **Google's Internal Deadline and Collaborators** [00:29] — Google has set an internal deadline to migrate its security to post-quantum cryptography by 2029. The study is a collaboration involving the Ethereum Foundation, Stanford, and Coinbase.
- **Broader Threat to All Systems** [00:41] — The same mathematics that protects Bitcoin also protects banks, email, and nearly every other digital system. If quantum computers could break Bitcoin, they would pose an even greater threat to the entire internet.
- **Bitcoin Would Be the Last Target** [00:55] — If attackers had such capabilities, they would likely target traditional banking and credit cards first, making Bitcoin the last thing to worry about.
- **Historical Precedent: Y2K** [01:09] — In 1999, predictions of Y2K causing planes to fall and banks to collapse were proven wrong after engineers fixed the issue. The speaker draws a parallel to the current quantum fear, suggesting it's similarly overblown.

### Conclusion

The video concludes that the real danger is not quantum computing itself but the fear and panic it generates, especially amplified by traditional media. It advises viewers to ignore the noise and trust that engineers will address the challenges, just as they did with Y2K.

## Transcript

published a very surprising study.  Breaking the cryptography that protects Bitcoin would require about 20 times fewer resources than previously thought.  From millions of cubits to less than half a million cubits in a matter
of minutes.  And here the noise and panic begin.  Half the internet is telling you, "Sell all your bitcoins now because it's over."  Let's go to the signal.  [music] capable of doing this.  That's why Google itself has set an internal deadline to
migrate its security to cryptography by 2029. And organizations like the Ethereum Foundation, Stanford, and Coinbase are collaborating on this study.  And second, and most importantly, the same mathematics that protects Bitcoin
also protects your bank, your email, and almost every other system to Bitcoin, it is an even greater threat to the entire internet world.  In fact, if they the last thing I'd worry about, since it would mean that they would have already
hacked traditional banking and all the credit cards in the world.  The real danger is not quantum physics, it's the fear surrounding it.  In fact, a technical fact is that in 1999 we were told that Y2K was going to bring down all
the planes in the world and even cause banks to collapse.  Spoiler alert: the engineers ended up fixing it and absolutely nothing happened.  So forget the fear and the noise, especially from traditional media.
