Top Podcasts on Bitcoin's Quantum Threat
Updated: Apr 29, 2026 – 12 episodes
The cryptocurrency market, including Bitcoin, is experiencing significant developments with the potential threat from quantum computing, increasing institutional adoption, and heightened regulatory scrutiny. These factors are shaping the future landscape of digital currencies, impacting their security, acceptance, and compliance requirements.
Three very different takes here — start with TBPN for the bear case on how quantum computing could crack Bitcoin's encryption sooner than expected. Silicon Valley Girl offers a more balanced view, discussing how proactive measures might mitigate these risks. Bankless provides a detailed breakdown of the potential threats to dormant Bitcoin, making it a must-listen for those concerned about long-term security. For a more optimistic perspective, The Milk Road Show argues that current technology is still far from compromising Bitcoin's security.

Podcast Episodes Covering This Story
“Google researchers have warned that future quantum computers may be able to break some of the cryptography protecting Bitcoin and other digital assets with fewer resources than previously thought, adding urgency to the debate over how the industry should prepare. The clearest defense is a shift towards post-quantum cryptography, or PQC, a newer form of security designed to withstand attacks from powerful machines.”
Ridealong summary
Quantum computing poses a real threat to Bitcoin's security, necessitating urgent adoption of post-quantum cryptography to prevent potential vulnerabilities.
“Max the VC says, Google is basically saying we've cut the quantum resources needed to break Bitcoin's encryption by 20x. We can now break it. We can prove it. We're just not going to tell you how. We've slowed down research to give crypto a chance. You have until 2029 to figure out a solution. Good luck.”
Ridealong summary
Quantum computing poses a real threat to Bitcoin's encryption, but the timeline gives the crypto community a chance to adapt before 2029.
“My understanding is if you have some of the older cryptocurrencies, that was encoded in a way that could be broken. But some of the newer versions, it's a little bit stiffer encryption. Is that Bitcoin, the oldest? I think this is Bitcoin, as I recall. So that one's... And then you can take your old Bitcoin and pull it out and then re-encrypt it to make it better. So you can make it safe.”
Ridealong summary
Quantum computing poses a real threat to Bitcoin's security, but proactive measures and regulatory discussions could mitigate risks.
“You've got 6.9 million bitcoin, a third of all supply, that is vulnerable to quantum attack. Now, some of that can be migrated except for the 2.3 million or so, which is 10 to 15 percent of all Bitcoin supply. That is Satoshi's keys and lost keys and keys that haven't been touched. These are assumed tokens that will never move because the owner is gone or dead or the private keys are lost.”
Ridealong summary
Bitcoin's vulnerability to quantum computing poses a significant threat, particularly to dormant coins, which could be exploited by future quantum computers.
“"They talked about a 20x reduction in the number of logical qubits required to break ECDSA which underpins Bitcoin cryptography... Even if Bitcoin does implement post-quantum algorithms, there's something to be done with that 2.3 million in supply. You could either do nothing, you could burn it... an hourglass approach to limit the rate that dormant coins can be spent."”
Ridealong summary
Quantum computing presents both a threat and an opportunity for Bitcoin, and the community must proactively adapt to harness its potential while mitigating risks.
“The Oratomic Caltech paper is the more concerning of the two. Because neutral atom systems, the biggest neutral atom array that exists already is 6,000 physical qubits. Does that collapse down with kind of air correction, like 50 or something logical? Yeah, so 6,000 physical, unclear what the exchange rate is logical. That's like the source of uncertainty. This oratomic paper doesn't actually talk about logical at all. It just says ECC could be cracked with between 10K and 26K physical qubits.”
Ridealong summary
Quantum computing poses an imminent threat to Bitcoin's cryptographic security, with advancements reducing the qubits needed to crack encryption significantly.
“There's a 50% chance that by 2033, you will have a cryptographically relevant quantum computer that can break Bitcoin. Whatever entity has the quantum computer owns all the Bitcoin on the network. This quantum computer can compute Shor's algorithm fast enough, then it's like every Bitcoin is basically at risk. Ownership fundamentally breaks.”
Ridealong summary
Quantum computing poses a significant threat to Bitcoin's security, potentially allowing a single entity to control the entire network.
“It's easy-ish to be quantum proof and there's thousands of people working at it around the world, including dozens of people in the Bitcoin space. They've already proposed, you know, pretty easy fixes. And, you know, a lot of this just comes down to, you know, you're basically safe if you have your Bitcoin at an address that's where the public key is not online anywhere, where you've never exposed the public key.”
Ridealong summary
Quantum computing poses a distant threat to Bitcoin, with current technology far from capable of compromising its security.
“What I think will happen is that the whole blockchain industry will copy Ethereum. Almost no one is tackling the hard problem, which is so-called signature aggregation. So one of the strategies that we're taking is to ironically partner with Bitcoiners. And the reason here is that if we can pill the Bitcoiners in using the same solution that we have, then we basically will create a de facto standard because the top two blockchains will have adopted it.”
Ridealong summary
Ethereum's approach to quantum resistance could set a new standard for Bitcoin, enhancing its security without compromising scalability.
“I still think even before we get to the policy and regulatory issues, there is still a lot of education that needs to be done about the commercial opportunity of engaging in DeFi. So like I said a lot of institutions now really understand that this is happening But usually an institution has a couple of guys right Like a few men and a few women who really understand the opportunity in crypto And they working really hard to convince everyone else at the institution who still thinks Bitcoin is all of crypto, right?”
Ridealong summary
Institutional adoption of crypto is hindered more by a lack of education and understanding than by regulatory issues.
“I think the right model for quantum is it's kind of crypto's Y2K and I think it's actually a really clean analogy because Y2K was a real problem right it was a huge coordination issue across the entire tech industry. It really would be catastrophic if unaddressed and it's really obvious how to fix... And then once you do that, the problem goes away.”
Ridealong summary
The quantum threat to Bitcoin is real and urgent, akin to the Y2K problem, requiring immediate industry-wide action to prevent future crises.
“"Ethereum has actually put out like a post-quantum roadmap of quantum proofing their network by 2029... So I think like the main concern is for Bitcoin. But I think like a big like takeaway from this is like, is there anything actionable like today? And I don't think there is because we're still, you know, five years out from, you know, at least five years out from the timeline that Google put out today."”
Ridealong summary
The main concern is for Bitcoin as it is more ossified compared to other blockchains, but immediate action is not necessary since quantum threats are still years away.
