Summary

Charlie Spears explores the existential threat of quantum computing to Bitcoin. Shor’s algorithm and the heated debate surrounding Satoshi’s 1 million BTC stash. We break down the difference between bits and qubits, explain why Shor's algorithm threatens elliptic curve cryptography, and debate the fate of Satoshi's vulnerable coins. It’s a deep dive into encryption, timeline predictions, and the massive coordination challenge facing the Bitcoin network to upgrade before it's too late. Subscribe to the newsletter: https://newsletter.blockspacemedia.com Notes: * Satoshi has ~1M quantum vulnerable BTC. * 2-4 million total BTC are currently exposed. * 10-20% of supply is vulnerable to Shor's algo. * Breaking BTC needs ~4,000 logical qubits. * Google’s Willow chip has 105 physical qubits. * NIST finalized quantum standards in 2024.

0:00.0	Every few months, Bitcoin dies again.
0:03.7	Bitcoin can tell it to $100,000 of Bitcoin before it goes down.
0:06.9	Bitcoin is going to zero.
0:09.7	Zero!
0:10.9	It's governments.
0:12.1	It's energy use.
0:13.5	It's tether.
0:14.6	It's China banning it.
0:16.4	Maybe Satoshi comes back.
0:18.4	But there's one threat that feels different, and this is a threat that
0:22.4	Satoshi themselves flagged back in 2010. Quantum computing.
0:27.2	It will come to a bad ending, Charlie. The predictions can be pretty terrifying.
0:32.4	Quantum.
0:33.4	Cheetah is coming. And honestly, a lot of these claims are plausible because quantum computers have a lot of
0:39.3	unknowns about them. So today, I'm asking the question, what would have to be true for quantum
0:47.1	computers to actually be a threat to Bitcoin? I'm Charlie Spears. This is Blockspace, and we're
0:53.2	going to talk about quantum computers and Bitcoin.
1:02.6	This is episode one in a multi-part series from Us of Blockspace on Quantum Computers. This is a 101, a more beginner-friendly episode. So if you don't know
1:12.2	anything, this is an explainer. There will be more episodes and we'll talk to some of the experts
1:17.6	to dive deeper into the subject. But before we go to Bitcoin, we have to zoom back and look at
1:24.0	quantum computing itself. I think a lot of people, myself included,
1:28.2	have this idea that quantum computers
