Quantum Storm: Are Bitcoin and Ethereum Ready for a Digital Doomsday?
Sure! Here’s the rewritten version of the article:
Brief Overview
Justin Drake cautioned that AI could potentially break Bitcoin’s ECDSA encryption using traditional computers, indicating this risk might emerge sooner than anticipated—within months, not years.
Approximately 7 million BTC valued at $580 billion reside in publicly exposed key addresses, constituting about one-third of Bitcoin’s overall supply.
The National Institute of Standards and Technology (NIST) will begin to deprecate existing signature methods post-2030, prompting Bitcoin to seek quantum-resistant enhancements through BIP-360.
Transitioning from portfolio building to living off it represents an entirely different set of skills, often overlooked in financial education. The free resource, The Definitive Guide to Retirement Income, addresses this gap. Learn more here. (Advertisement)
According to Justin Drake from the Ethereum Foundation, the cryptocurrency community should “methodically prepare for a ‘bunker mode’,” which entails moving digital assets to new addresses designed to conceal their public keys. This alert has reignited discussions regarding a critical concern for Bitcoin (CRYPTO:BTC) and Ethereum (CRYPTO:ETH) holders: are quantum computers capable of undermining Bitcoin’s security?
Interestingly, Drake’s worries are less about quantum technology directly. He pointed instead to the rising menace of artificial intelligence that can swiftly tackle intricate math problems, implying the risks could present themselves in “months, not years.” Nevertheless, he provided reassurance, indicating that there is no immediate cause for alarm or hasty actions. So, how imminent is the prospective threat to Bitcoin’s security, and which cryptocurrencies might be at risk?

Drake’s Concerns Focus on AI Mathematics Rather Than Quantum Tech

Drake connected his worries to OpenAI’s generation of 722 mathematical papers produced by an internal AI model, stating that “mathematical superintelligence is here.” He expressed concern that such technologies could uncover methods for retrieving private keys from public keys using conventional computing resources.
This risk could predominantly affect the Elliptic Curve Digital Signature Algorithm (ECDSA), which Bitcoin utilizes to confirm ownership of coins. Michael Gutkin, a senior researcher at Fireblocks, clarified that Drake’s scenario signifies a “classical breach,” rather than a quantum-related one. He also noted that no successful demonstrations of such an attack have occurred, and the actual probability remains contentious.

Currently, quantum computers lack the capability to breach Bitcoin’s security. The debate regarding when this might change remains ongoing, while Ethereum’s guidelines currently affirm that quantum technology cannot compromise the network’s cryptographic safeguards.
A Significant Portion of Bitcoin Is in Public Key Exposed Addresses
24/7 Wall St.
Every Bitcoin wallet is initialized with a private key, a confidential number known solely to the owner. This private key transforms into a public key, while hashing turns the public key into a wallet address. Although addresses can be easily derived from keys, Bitcoin’s protective measures ensure that attackers cannot reverse the process.
Older wallet addresses can reveal public keys since their inception, while newer formats keep public keys concealed until transactions take place. However, once a transaction occurs, the public key is permanently exposed. According to Project Eleven’s tracker, over 14 million funded Bitcoin addresses have their public keys visible.
Gutkin estimates that between 6.7 million and 7 million BTC are held in these exposed addresses, valued at around $550 billion to $580 billion based on a price of $82,462 per Bitcoin—approximately one-third of the entire supply. Drake noted that attackers might focus on around 20,000 earlier addresses connected to Satoshi Nakamoto, each containing 50 BTC, aggregating about 1 million BTC worth an estimated $82 billion.
Urgent Protocol Enhancements Needed Before NIST’s 2030 Deadline

An impending deadline looms due to NIST, the U.S. body responsible for establishing federal security protocols. Gutkin indicated that after 2030, NIST will begin to phase out current signature methods and fully ban them by 2035. He highlighted that blockchains cannot rapidly adjust to such extensive modifications.
In contrast, Ethereum seems to be ahead in this aspect. A team from Fireblocks has managed to cut the cost of validating a quantum-resistant signature on Ethereum from 8.09 million gas to 1.23 million gas. Nonetheless, this code is still pending an evaluation. Unlike Ethereum, Bitcoin lacks the adaptable programming framework required for such enhancements, meaning it fundamentally requires protocol support, as noted by Gutkin.
Bitcoin developers have introduced BIP-360, an initiative aimed at creating a new address type that conceals its public key. While this adjustment would “lessen long-term vulnerability,” Gutkin pointed out that it does not provide a complete remedy. Other networks, like XRP, claim they are in a superior position, asserting that only 0.03% of their supply is at risk. Furthermore, a mass migration to relocate Bitcoin could burden the network’s limited space, leading to increased fees and slower transaction confirmations.
Are Quantum Computers Capable of Breaching Bitcoin?
As of October 2026, quantum computers remain incapable of breaching Bitcoin’s defenses, and the AI-related mathematical advantage Drake referenced has yet to be validated. Upcoming deadlines are far more relevant than hypothetical dangers, as NIST’s 2030 and 2035 cut-offs provide Bitcoin with a limited timeframe to transition to quantum-safe addresses.
Nonetheless, executing these modifications incurs expenses, particularly since approximately 1 million BTC linked to early Satoshi-era addresses can only be transferred with the owner’s consent. This implies that a voluntary migration may leave those coins still vulnerable. Should a researcher successfully derive an ECDSA private key from a public key through existing technology, the suggested “bunker mode” could evolve from a precautionary strategy to an urgent requirement. Meanwhile, Bitcoin developers advocating for BIP-360 or similar upgrades will serve as key indicators for long-term investors to watch closely.
Launched: The Definitive Guide to Retirement Income
(Advertisement) Many individuals devote their entire working lives to accumulating wealth, only to find that the true skill needed in retirement is nearly the opposite: converting that wealth into a reliable income stream over the years, regardless of market conditions, without exhausting the funds.
This transition, often the least discussed yet most impactful phase of personal finance, catches many prudent investors off guard without a solid plan. This is precisely the challenge that The Definitive Guide to Retirement Income addresses. This complimentary guide from Fisher Investments explores the actual expenses of retirement, the various income sources available, and the calculations needed for secure annual withdrawals.
