.Sui has a massive headstart and the most flexible architecture for the post-quantum and AI era. This conversation with Kostas Kryptos tells you exactly why, and what every other chain still has to figure out. If you hold anything onchain, watch this pod. Timestamps: 0:00 Intro 6:00 What a quantum computer actually is (the 10-year-old version) 10:00 Quantum will be used for trading before it ever breaks Bitcoin? 13:00 Post-quantum algorithms (solved) vs hardware (decades out) 17:00 "If you think quantum breaks crypto by 2030, you can make free money" 19:00 Everyone missed this: AI is now researching quantum alongside humans 25:00 The post-quantum-algorithm debate: Falcon, Dilithium, Sphincs and why each chain picks differently 27:00 Why Bitcoin will ONLY adopt hash-based post-quantum algorithms 31:00 This is why Sui's architecture wins: 128KB transactions, native multi-sig, flexible authenticator 36:00 How Sui can natively support any signature scheme 40:00 The Sui-only algorithm: protect existing EdDSA addresses without moving a coin 44:00 Design philosophy: what Sui kept from Libra, and what it threw out 47:00 Why Sui can keep gas low even with post-quantum signatures 49:00 How Kostas first started working on this in 2016 at R3 Corda 51:00 Attending tech conference one day after his son was born: meeting Sam Blackshear , joining Libra 55:00 The bigger near-term threat: AI-aided attacks, not quantum 58:00 Why Mysten Labs is now sharing its security tooling with the community 1:02:00 Sui's $100K post-quantum bounty: break it, keep it

People are losing their minds over the idea of quantum computing breaking Bitcoin, but the panic is largely detached from reality. If you listen to Eric Yakes, the fear-mongering is completely off base. The theoretical threat relies on quantum computers factoring large prime numbers fast enough to crack current cryptography. To date, the largest number a quantum computer has successfully factored is 15. "Neven's Law" says quantum power grows at a doubly exponential rate. It's a projection people are using to raise money for their projects, rather than a measurement we are seeing in real life. Compare that to Moore's Law, which we actually watched happen in real time. While physical qubits are increasing and error rates are slowly declining, there is a massive technical hurdle: error rates scale exponentially with qubit count. Adding more power creates more "noise," making the machine harder to stabilize. "But institutional capital is worried!" That's fine. Institutional capital has been wrong about Bitcoin for a decade. If they're selling on quantum FUD, that's cheap sats for the rest of us. Bitcoin devs have been on this for years and are taking steps to mitigate the risk. BIP-360 was just merged into the Bitcoin GitHub repository and Chaincode Labs has published plenty of serious research. If a real threat emerges, every stakeholder is incentivized to adopt quantum-resistant signatures and consensus won't be the obstacle people think it is. Start paying attention to what's actually being built and take your finger off the panic button. Full breakdown 👇

BREAKING: THE MOST IMPORTANT VIDEO TO WATCH IF YOU ARE INVESTED IN QUANTUM COMPUTING COMPANIES. $IONQ $RGTI $QBTS $QUBT The world's leading quantum computing researcher Scott Aaronson calls out the scams and snakeoilmen in the public quantum computing stock market. $IONQ $RGTI $QBTS $QUBT - "The most important thing that I can say in this whole interview, if I am taking to Retail investors is that unfortunately there are companies that I see that are really trying to solve the hardware problems, they might succeed, they might fail but they are really focused on solving the real problems and talking about it more or less honestly" - "and then there are companies that have focused on like marketing themselves to Retail investors and doing IPO's" i.e. the 4 public quantum computing companies IONQ, Rigetti, D-Wave and QUBT. - "and I see these 2 sets of companies being mostly disjoint from each other" - "So the companies that have focused on doing IPO's are actually not the ones that are in the lead on in the hardware, what they are in the lead on is selling a narrative to people...... - "convincing people this is already useful for solving problems in optimization and machine learning and finance, which sounds great to people, but all depends on you agreeing to not ask the question Q. well could a classical computer have done that just as well, could a classical computer actually have done that much faster and easier " "When people are talking about that the big use of a quantum computer is to solve optimization or machine learning problems or to turbo charge AI, or it can already do this, it's already delivering value to customers...." "these are the tells you are dealing with a SNAKEOIL SALESMAN" He calls out the "scammy" companies in this space! Remember the only 4 quantum pure play companies that have IPO'd are $IONQ $RGTI $QUBT $QBTS He also says earlier in the interview “I would say $IONQ has not demonstrated anything in trapped ion hardware close to what Quantinuum has demonstrated in the last year” YOU ARE BEING LIED TO!

BITCOIN RAILS #61: QUANTUM CRYPTOGRAPHY FOR BITCOIN | with Dan Boneh Dan Boneh 🔗 YOUTUBE: 🌿 SPOTIFY: One of the most prolific and influential cryptographers in the world, it’s difficult to fully quantify the impact that Dan Boneh has had on Bitcoin and digital assets more broadly. Through both his own research and his mentorship of some of the space’s most important contributors — e.g. Andrew Poelstra, Benedikt Bünz ☕️, and Robin Linus — few people have done more to shape the cryptographic foundations underlying modern blockchains and digital finance. More recently, Dan co-authored Google's widely discussed paper, “Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities,” which reduced prior estimates of the resources required to run Shor’s algorithm against the elliptic-curve cryptography used by Bitcoin. The paper reignited debate around quantum computing timelines and the long-term security assumptions behind modern cryptocurrencies. In this episode of Bitcoin Rails, Dan and I discuss the current state of quantum computing, its potential implications for Bitcoin, and how he believes the Bitcoin community should think about preparing for a post-quantum future over the coming decade and beyond. And yes, Dan shares his take on the “when quantum” question in the interview, among other key perspectives. This episode of Bitcoin Rails is brought to you by my NEW sponsors: LayerTwo Labs LayerTwo Labs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) Hashi on Sui — a primitive for executing Bitcoin Defi transactions, without having to trust a federated bridge or other centralized entity BitBox BitBox — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.
