XRP Ledger’s Post-Quantum Push: What Ripple Is Actually Doing to Prepare Ripple has published a multi-phase roadmap to make the XRP Ledger resistant to quantum computing attacks, aiming to achieve full post-quantum readiness by 2028. The move comes after Google Quantum AI research confirmed that the cryptography underpinning most blockchains today can, in principle, be broken by sufficiently advanced quantum hardware. Assets are not at risk today. But the threat has shifted from theoretical to credible, altering the preparation timeline. The question isn’t whether quantum computing will eventually matter for crypto. The question is whether XRP holders need to do anything about it right now. BSCN@BSCNewsApr 20, 2026RIPPLE: $XRP LEDGER WILL BE QUANTUM RESISTANT BY 2028@Ripple is making its $XRP Ledger quantum-ready.

Think of your XRP wallet like a padlock secured with a math problem so hard that no computer today could crack it in a reasonable timeframe. Quantum computers don’t just work faster; they approach certain math problems in a fundamentally different way, like having a master key that can solve the puzzle directly. The specific algorithms that protect blockchain wallets and transaction signatures are vulnerable to this kind of attack. There’s a subtler threat layered on top of that. Researchers call it “harvest now, decrypt later.” Every time an XRP account signs a transaction, its public key becomes visible on-chain. A bad actor could quietly collect that data today and hold it, waiting for quantum hardware to mature enough to use it. By the time the attack is technically possible, the groundwork will already be laid. Ripple is

Is Crypto Safe From Quantum Computers? Coinbase Says Yes A newly formed brain trust of top-notch cryptographic researchers has determined that your digital assets are safe from quantum computers today. However, the clock to secure them for the future is now ticking. Coinbase has published the first position paper from its newly assembled Independent Advisory Board on Quantum Computing and Blockchain. The council features top researchers from Stanford, UT Austin, the Ethereum Foundation, Eigen Labs, Bar-Ilan University, and UC Santa Barbara. It has been determined that a quantum machine capable of breaking modern blockchain cryptography does not yet exist, but its eventual creation is essentially inevitable. A sufficiently powerful quantum computer is likely at least a decade away, but the industry has to start preparing now. Where the real vulnerabilities lie Core infrastructure is largely secure. Bitcoin mining, hash functions, and the historical records of major blockchains are not threatened by quantum advancements in any meaningful way. However, wallets are vulnerable, and the board estimates that 6.9 million BTC currently fall into this highly vulnerable category. Networks using proof-of-stake consensus face additional exposure through the specific signature schemes validators use to secure the network. The cryptographic community has been developing quantum-resistant alternatives for over two decades, and the U.S. National Institute of Standards and Technology (NIST) has already standardized several new security schemes. The problem lies with the fact that new quantum-safe signatures are substantially larger in data size. Their integration will negatively affect transaction speeds and other aspects. Furthermore, coordinating a migration across millions of decentralized users is extremely cumbersome. The multibillion-dollar question What happens to wallets that never upgrade?

Here’s what you’ll learn when you read this story: - Scientists are using terahertz waves to study tiny structures in brain cells, called microtubules, that may be linked to consciousness. - Early experiments suggest microtubules behave differently under anesthesia—when consciousness is clearly altered—but evidence remains inconclusive. - Now, researchers are debating whether quantum effects in the brain are real, measurable, or simply theoretical. If you’ve been in an airplanebefore, it’s probably happened to you: walking through an airport body scanner, a dreaded Beep! Beep! Beep! resounds, signaling that it caught some forgotten coin, key, or even a crumpled receipt that you mistakenly left in your pocket. That moment comes courtesy of millimeter waves, otherwise harmless high-frequency radio signals that bounce off your body to reveal hidden objects. Terahertz (THz) waves are close relatives of millimeter waves, but they sit even higher on the electromagnetic spectrum, meaning they can read the subtle vibrational “fingerprints” of molecules without the damaging effects of x-rays. That makes them especially useful for studying soft, shifting structures like microtubules as they move inside living cells. But rather than use them to find loose change, scientists are aiming terahertz waves at the brain itself. Their mission? To see if microtubules—the cell’s tiny scaffolding tubes—flutter with quantum vibrations that vanish under anesthesia and rebound when consciousness returns. Data from animal studies suggests this is the case. In 2024, researchers at the University of Maryland gave rats compounds that stabilize microtubules. They noticed that the animals took longer to lose consciousness under anesthesia—an indication that these protein tubes could play a role in awareness. Rather than using terahertz scanners, the team altered the microtubules directly to see how the brain responded. But studying microtubules inside a living brain is far trickier—you can’t just tweak them with drugs and watch

Coinbase Advisory Board Paper Warns Crypto Cannot Afford to Wait on Quantum Threats A 50 page quantum computing crypto risk assessment published Tuesday by Coinbase’s independent advisory board concludes that while today’s blockchains remain secure, a fault-tolerant quantum computer capable of breaking widely used encryption is increasingly plausible and that preparation must begin now, warning that “waiting for it to be urgent is not a good idea.” - The 50 page paper, authored by an independent board including Stanford cryptographer Dan Boneh, Ethereum Foundation researcher Justin Drake, and EigenLayer founder Sreeram Kannan. - Replacing today’s signatures with quantum-resistant alternatives could expand blockchain data sizes by up to 38 times, according to one estimate in the report, meaning the transition carries significant engineering costs and performance tradeoffs. - Bitcoin wallets that have already revealed their public keys are identified as the most immediately vulnerable category of holdings in any future quantum attack scenario. Quantum computing crypto risk has its most authoritative industry assessment yet. The Coinbase advisory board, a group of world-class cryptographers and blockchain researchers convened by Coinbase in January 2026, released its first major position paper Tuesday: a 50 page analysis of how future quantum computers could affect blockchain security and what the industry must do before that threat becomes real. “Waiting for it to be urgent is not a good idea,” the paper states, emphasizing that transitions across blockchains, wallets, and exchanges could take years to execute safely even after all the technical standards are in place. The board members who authored the paper include Dan Boneh, the director of the Stanford Center for Blockchain Research; Justin Drake of the Ethereum Foundation; Sreeram Kannan, the founder of EigenLayer; Yehuda Lindell, Coinbase’s head of cryptography; and Dahlia Malkhi, an expert in resilient distributed systems.

- Ripple detailed a two-year roadmap that would have XRP Ledger quantum ready by 2028. - Quantum computing has sparked fears across the cryptocurrency industry. - Experts predict a quantum computer able to crack blockchains' encryption models will arrive between two and eight years from now. The spectre of quantum computing is coming to a crypto network near you. Ripple, the company that created XRP, is racing ahead to make its XRP Ledger quantum-proof by 2028, acknowledging that the threat quantum computers pose to crypto networks has hastily moved “from theoretical to credible.” On Tuesday, the company put out a statement saying it’s testing quantum-resistant technology alongside its existing systems, while working with partners to accelerate development. “Recent research from Google Quantum AI is bringing renewed attention to what quantum computing could mean for the crypto industry,” Ripple wrote. “The findings show that the cryptography most blockchains rely on today can be broken by sufficiently advanced quantum computers.” Ripple now joins the two top crypto networks — Bitcoin and Ethereum — in attempting to stave off quantum computers, a still-theoretical yet fast-advancing technology that has the potential to break blockchains en masse. Indeed, the issue has become a stormy one for crypto enthusiasts, developers, and investors. Today there aren’t any quantum computers able to break crypto networks, although researchers point to a strategy called “harvest now, decrypt later,” wherein hackers can collect public data from blockchains today and wait for quantum computers to mature enough to crack it. Researchers at Chaincode Labs said that up to 50% of all Bitcoin is at risk of a future quantum computer. Many Wall Street bigwigs have said that developers maintaining Bitcoin need to take the threat more seriously. Four-phase plan Ripple's roadmap consists of four phases.

Nearly 50 years ago, in 1979, I sat in a classroom on the beautiful campus of Rollins College in Winter Park, Florida. I was in my final year at Rollins before starting the second part of a five-year dual-degree program at the Georgia Institute of Technology (Georgia Tech) in Atlanta. At Rollins, my three-year focus was physics, and, ultimately, my two-year focus, excluding grad school at Georgia Tech, was Electrical and Computer Engineering. The most memorable class at Rollins was P451, Quantum Physics, because it was both challenging and fascinating, revealing mysteries of this advanced science. Each day, my curiosity led me to ask myself what I would ever do with any of this knowledge. The book used for the class was “An Introduction to Quantum Physics” by A. P. French and Edwin F. Taylor. It still sits on the shelf of my home office, and I shake my head each time I look at it. Quantum physics, also known as quantum mechanics, is a branch of physics that explains how nature operates at its most fundamental levels, including the behavior of atoms, electrons, and photons. It may not be evident to most of us, however, that quantum physics is the foundation for much of modern technology, including semiconductors used in every electronic devices such as computers, smartphones, and household appliances, as well as in automotive applications, optical devices like lasers, and healthcare products like MRI machines; it is also fundamental to the emergence of quantum computing because these new quantum systems will use the principles of quantum physics to process information beyond the capabilities of today’s classical computers. My final reflections on this quantum physics class centered on learning about Erwin Schrödinger, an Austrian physicist and one of the founding figures of quantum mechanics, and the magnitude of the

- Zero-knowledge systems powering mixers like Railgun and PrivacyPools are immune to quantum attacks, researchers find. - They urge vulnerable crypto projects to prepare, but say the sky is not falling. Crypto privacy protocols are immune to the threat of quantum attacks on Bitcoin and other digital assets, researchers have found. Zero-knowledge proof systems, including networks such as Aleo and Aztec, and mixers such as Railgun and PrivacyPools, rely on information-theoretic systems which are secure even against infinitely powerful attackers because of how information is structured and shared, not because of encryption. That makes them mathematically immune to quantum attacks, according to a Coinbase-led study co-authored with researchers from Stanford and the Ethereum Foundation, and shared with DL News. Their findings come amid growing concern over rapid advances in computing hardware that are expected to impact cryptographic systems. That threat has been heard at the top of Wall Street. In January, finance leaders, including UBS CEO Sergio Ermotti, Jefferies’ head of equity strategy Christopher Wood, and hedge fund manager Ray Dalio, all sounded the alarm on Bitcoin’s vulnerability. In March, Google shook the crypto world with a report warning that new quantum computers could crack the encryption that protects Bitcoin, Ethereum and other cryptocurrencies in as little as nine minutes. “We firmly believe that a large-scale fault-tolerant quantum computer will eventually be built, and that blockchains need to prepare for this eventuality,” the study said. At the same time, the report makes clear that the threat is not imminent and that preparation — not panic — is the correct response. It is a recommendation shared by brokerage firm Bernstein, which described quantum computing earlier in April as “neither existential, nor novel, and also not limited to crypto.” Who’s most vulnerable?

Ripple Unveils Strategy to Shield XRP Ledger from Quantum Threats Ripple reveals plan to prepare XRP Ledger for quantum computing era by 2028. The company Ripple has unveiled a multi-phase strategy to prepare the XRP Ledger (XRPL) for the era of quantum computing. The network is expected to be fully prepared for new threats by 2028. Post-quantum readiness on XRP Ledger (XRPL) is not a single upgrade. It is a fundamental architectural shift in how digital assets are secured over the long term. This transition will impact key management, validator infrastructure, and how users interact with the network. We⦠â J. Ayo Akinyele (@ja_akinyele) April 20, 2026 According to the roadmap, XRPL will transition to quantum-resistant cryptography in four phases. Developers emphasized that while the threat is not immediate, practical steps are necessary due to accelerated research in the field. The key risk is the “harvest now, decrypt later” scenario, where attackers collect encrypted data today to decrypt it in the future using quantum computers. The Transition Process The plan involves two parallel approachesâgradual migration and an emergency scenario in case of Q-day (the moment classical cryptography is broken): - emergency readiness: the network will be able to forcibly transfer users’ funds to secure format addresses if current algorithms are compromised; - testing and integration (first half of 2026): implementation of quantum-resistant signatures alongside current transaction processing mechanisms in testnets; - controlled transition (first half of 2026): exploration of new primitives, including zero-knowledge proofs and homomorphic encryption; - full migration (targetâ2028): transition of the entire network to new standards by 2028. “In the final stage, the task goes beyond cryptography and is more about ensuring that we do not disrupt the existing XRPL mechanisms. This will require careful work and coordination with ecosystem partners,” the developers noted. XRPL Features Ripple

AES-128 Will Survive Cryptographically Relevant Quantum Computers Math Doesn’t Lie Ars Technica posted a bit of a delve into the math behind using a quantum computer to break AES-128 encryption and the news is good. The rumour has always been that QRQC will halve the amount of work needed to crack algorithms like AES-128, rendering it relatively quick to crack and that we would have to use AES-256 at the very least. However, that math does not check out. Two mathematicians tried to express the somewhat complex math by using much smaller numbers. Instead of the 3.4 x 10^38 possible combinations that AES-128 boasts, they reduced it to a possible 256 combinations for their examples. If you split the work four ways, then each of you could try 32 combinations which is a reasonable amount of work. However quantum computers do not behave the same as classic computers and when you assign several of them parallel tasks they use Grover’s algorithm to split the work. If you break apart the task between several quantum computers, the amount of tries they have to chew through ends up being the same, not half the tried as the doomsayers have been predicting. Follow the link to read “Quantum Computers Are Not a Threat to 128-bit Symmetric Keys” if you want to read a proper explanation of why AES-128 is not going anywhere … yet. “What makes Grover special is that as you parallelize it, its advantage over non-quantum algorithms gets smaller,” Valsorda said in an interview.

Bringing quantum-centric supercomputing to Illinois IBM’s Hanhee Paik developed IBM’s first 16-qubit quantum computer and now leads IBM’s quantum initiatives across greater Chicago. We spoke to her about the new IBM-University of Illinois agreement, the future of computing, and how her career path has mirrored quantum’s remarkable rise. Superconducting qubits take many forms. The one at the heart of IBM quantum processors, the transmon qubit, is there partly because of Hanhee Paik. By figuring out how to improve the transmon qubit’s coherence time, Paik showed the world that a superconducting quantum computer was possible. IBM now operates a fleet of quantum computers worldwide based on her transmon qubit design. Today it’s Paik’s job at IBM to help researchers find innovative ways to use them. She currently oversees several projects in Chicago, including the National Quantum Algorithm Center (NQAC) that IBM recently established with the state of Illinois, and whose members include the University of Illinois Urbana-Champaign (UIUC) and the University of Chicago. IBM just signed a new agreement with UIUC to expand the Discovery Accelerator Institute, with the goal of advancing quantum-centric computing and developing algorithms that combine the strengths of HPC and quantum computing to achieve transformational results. IBM will give UIUC students and researchers access to IBM Quantum computers alongside UIUC’s National Center for Supercomputing Applications (NCSA) Delta and DeltaAI supercomputers. This “quantum-centric” architecture will allow researchers to test new algorithms and explore quantum use cases in the real world. Without algorithms, we can’t really use quantum computing to solve problems and develop the economy. Paik will help drive the agenda, drawing on her deep expertise in quantum systems and her growing knowledge of high-performance computing, picked up on a recent assignment in Japan. We recently caught up with her to talk about IBM’s collaboration with UIUC, and
