Google research flags quantum attack risk as Ethereum advances post-quantum roadmap

New research involving Google warns that quantum computers with approximately 1,200–1,450 logical qubits could break elliptic curve cryptography—including the secp256k1 standard used in Bitcoin and Ethereum—within minutes. The study highlights two primary risks: “on-spend” attacks, where a quantum system could derive a private key during the 9–12 minute transaction confirmation window, and “at-rest” attacks on dormant wallets with exposed public keys. In response, Ethereum has launched a multi-year post-quantum roadmap aimed at transitioning to quantum-resistant cryptographic system across its protocol layers. However, the shift introduces challenges such as larger signatures, higher computational demands, and the need for coordinated upgrades. User migration to new wallet standards and the vulnerability of older assets also remain significant hurdles. While quantum threats are not immediate, the research underscores the importance of proactive preparation to mitigate long-term risks. Industry leaders like Changpeng Zhao acknowledge that, although transition is feasible, decentralized coordination and potential forks could complicate the process.

Ethereum outlines multi-year plan to transition to quantum-safe cryptography

The Ethereum Foundation has launched a dedicated hub to coordinate its post-quantum security efforts, initiating a multi-year plan to transition the Ethereum network to quantum-resistant cryptography. Although a cryptographically relevant quantum computer is not yet imminent, the Foundation emphasizes the need for early preparation due to the complexity of upgrading a global decentralized system. The transition will be a multi-layered process, impacting the execution, consensus, and data layers of the protocol. Efforts include enabling quantum-safe authentication for users, replacing validator signature systems, and securing data availability. A major challenge is balancing enhanced security with scalability, as post-quantum cryptographic schemes often require more computational resources and produce bigger signatures. Researchers are exploring aggregation techniques and zero-knowledge proofs to maintain efficiency. This initiative, built on over eight years of research, marks a shift from isolated studies to a structured, public roadmap. By starting early, Ethereum aims to ensure long-term resilience and avoid disruptive upgrades in the future, positioning the network to remain secure for decades to come.

Ethereum Unveils Post-Quantum Security Roadmap For Institutions

Ethereum has publicly formalized its post-quantum security roadmap, targeting a critical threat to its cryptographic foundations. Presented at the Institutional Ethereum Forum, researcher Will Corcoran outlined the risks quantum computers pose to elliptic-curve cryptography, which secures validator attestations, transactions, and wallet signatures. The core challenge is not just replacing signatures but managing the trade-offs: the proposed hash-based scheme, LeanSig, is significantly larger than current BLS signatures, threatening bandwidth and decentralization if naively implemented. Ethereum's solution pairs LeanSig with a STARK-based aggregation engine called Lean Multisig to compress signature data, making it viable. With a cryptographically relevant quantum computer estimated by 2032, Ethereum is targeting key upgrades for its 2029 hard fork. The effort, involving extensive research and testing, is positioned to set a new industry standard for all proof-of-stake blockchains facing this unavoidable scaling problem.

Bitcoin Is Rising To The Quantum Challenge, Galaxy Report Says

A Galaxy Digital report states that while Bitcoin faces a genuine threat from future quantum computers, the network is actively preparing rather than ignoring the risk. The analysis highlights that not all Bitcoin is equally vulnerable—only funds with exposed public keys, such as those in legacy wallets, reused addresses, or certain custodian setups, are at risk. Approximately 7 million BTC could be considered exposed under a broad definition. Bitcoin’s UTXO model provides inherent protection, as public keys are typically revealed only when coins are spent. Developers are already working on solutions, with BIP 360 (Pay-to-Merkle-Root) emerging as a leading proposal to reduce quantum risk via a soft fork. Additional ideas, such as hash-based signatures and mechanisms like Hourglass, aim to protect already-exposed coins and limit potential damage. Although Bitcoin upgrades move slowly, the report emphasizes that incentives are uniquely aligned to address this threat, as no one benefits from quantum vulnerability. The overall message is clear: the quantum risk is serious and concrete work is underway to mitigate it.

Saylor Says Bitcoin Could Win Big If AI Destroys Traditional Moats

Michael Saylor argues that Bitcoin could become a major beneficiary if artificial intelligence undermines long-term corporate moats and compresses traditional equity valuations. This view responds to Chamath Palihapitiya’s thesis that AI could accelerate disruption, making competitive advantages temporary and forcing investors to drastically reprice stocks based on near-term cash flows rather than long-dated growth. Palihapitiya suggested that heightened disruption risk could compress market multiples, potentially leading to a significant devaluation of equity markets. Saylor contends that in such a scenario, capital would shift to assets immune to AI disruption—specifically Bitcoin, which he describes as scarce, neutral, and resilient. The debate later turned to quantum computing risks, with Palihapitiya questioning Bitcoin’s resilience, while Saylor argued that quantum threats would affect the entire digital infrastructure, not just Bitcoin. Other industry figures, including BitGo’s CEO and Helius Labs’ CEO, offered nuanced perspectives on Bitcoin’s comparative vulnerabilities and strengths in a post-quantum world. At the time of writing, Bitcoin was trading at $74,140.

BIP-360 Explained: Bitcoin Takes Its First Step Towards Quantum Resistance, But Why Is It Only the 'First Step'?

BIP-360 introduces a quantum-resistant upgrade to Bitcoin by proposing Pay-to-Merkle-Root (P2MR) scripts, which remove the key-path spending option in Taproot to minimize elliptic curve key exposure—a primary vulnerability in a future quantum computing scenario. This marks Bitcoin’s first formal step toward quantum defense, though it is a cautious and incremental update rather than a full cryptographic overhaul. P2MR retains support for complex scripts like multisig and timelocks via Taproot’s Merkle tree structure, ensuring smart contract flexibility. However, it does not upgrade existing UTXOs or replace ECDSA/Schnorr signatures with post-quantum alternatives. Wallets and services may gradually adopt P2MR addresses, but broader ecosystem coordination and user migration will be required over time. The proposal reflects Bitcoin’s proactive approach to long-term security amid advancing quantum computing research.

Is Quantum Computing A Threat To Bitcoin? ARK Invest Breaks It Down

ARK Invest and Unchained's research paper examines the potential threat quantum computing poses to Bitcoin's cryptography. The authors conclude it is a legitimate long-term concern but not an imminent threat. Current quantum systems are in the "NISQ era" with limited qubits and high error rates, far from the estimated requirement of at least 2,330 logical qubits to break Bitcoin's encryption. The report describes quantum development as a gradual progression, not a sudden event, providing ample warning and time for the market and network to adapt. It estimates that roughly 35% of Bitcoin's supply could theoretically be exposed, but many of these coins are either lost or can be migrated to safer address formats. The paper highlights that meaningful quantum breakthroughs would disrupt broader internet security first, triggering a coordinated response. While the technical risk is distant, it raises future governance challenges, as upgrading Bitcoin's cryptography would require community consensus. The authors frame the issue as a manageable long-term engineering problem rather than an abrupt point of failure.
