Exploring the intersection of Bitcoin and Quantum Computing

Life imitates Bluey Minisode S01 Episode 8 - Tattoo Shop

Perth BitDevs - Tonight 6pm at Phat Brew Good mix of topics this month including: - Perth bloke launches NostrMQ @Pete Winn 🔆 - The filter wars continue and even escalate - Node fingerprint attacks - CTV and CSFS letter and mailing list discussions - BitVM3 and garbled circuits - Descriptor encrypt - Bitcoin Treasury update - Ashigaru Whirlpool & Terminal - Frostsnap device released Hope to see you there!

Had a great chat with @Stephan Livera along with my co-author Clara in talking about Quantum Computing and what it means for Bitcoin. (Now I see why a good mic is essential…)

What Happens To Bitcoin When Quantum Computers Arrive?

A high level overview of the recent report by Chaincode Labs on the threat quantum computing poses to Bitcoin.

If you didn’t make it through the original report this is a nice and short summary 🤗

“Flowers may bloom again, but a person never has a chance to be young again” Bluey - Takeaway Season 1, episode 14

Moving Forward ⏩ This report shows that the Bitcoin community has long been aware of the threat posed by CRQCs and has been debating and discussing Bitcoin’s response for some time. However, the window for careful, deliberate action exists today, and will narrow as quantum computing advances. This makes proactive preparation not merely prudent, but essential for Bitcoin's long-term survival.

Post Quantum Cryptography (PQC) Efforts in Bitcoin 🧑‍💻 Several leading cryptographers and Bitcoin developers have been joined by a number of new and enthusiastic contributors to design, develop and discuss approaches for Bitcoin’s quantum readiness. While there are a number of existing proposals, this is a rapidly evolving area of research, so it is expected that there will be many improvements in PQC and its application to Bitcoin in the near future.

Burn vs. Steal Dilemma 🤔 Preparing Bitcoin for CRQCs isn’t just a technical challenge, it’s a philosophical one. Should quantum-vulnerable coins be burned or allowed to be stolen by those with CRQCs? This question strikes at Bitcoin’s core principles of property rights, censorship resistance, and conservatism, and may be the most significant test of Bitcoin's decentralised governance model to date.

Bitcoin Mining Resilience 💪 The use and impact of quantum computers for Bitcoin mining, quantum mining, is a different story. Quantum miners would have to compete with highly specialized and optimised ASICs. Grover’s algorithm offers a limited advantage and can’t be parallelized like classical mining. Mining is expected to remain more quantum-resilient than transaction signatures.

Elliptic Curve Cryptography (ECC) Weakness ❗ The ECC-based signatures used in Bitcoin are vulnerable to being broken by CRQCs, putting an estimated 4-10 million BTC ($400B-$1T) at risk - representing 20-50% of Bitcoin's ~19.9 million total supply. Funds most vulnerable to CRQCs are large institutional and exchange holdings, where public keys have been exposed due to "address reuse" practices, and Satoshi-era funds due to script type.
