Proactive Measures Over Passive Shifts
Instead of relying on address rotation, Qureshi urged blockchain networks to adopt proactive defenses against AI-driven cryptographic attacks. He proposed a Cryptographic Recovery Mode — a hash-based backup system for signatures that users could link to their addresses. This would allow validators to enforce automatic recovery if signatures fail, without moving funds. The mechanism prepares infrastructure to react swiftly and securely when cryptographic security is compromised.

Bitcoin Faces Deeper Drop in Uptober, Experts Cite Key Support LevelsGlassnode Data Shows Massive Exposure
According to Glassnode, over 31% of Bitcoin’s total supply — roughly 6.26 million BTC — is vulnerable to AI or quantum computing breaking cryptographic signatures. Of that, about 4.33 million BTC are exposed due to address reuse. If corrected by moving funds to new addresses, this vulnerability could be eliminated. The remaining 1.94 million BTC are at risk due to specific address formats, as detailed by Rafael Schultze-Kraft, cofounder of Glassnode, in an X post on Thursday.
Exchange Holdings Heighten Systemic Risk
Approximately 1.8 million of the exposed BTC — around 57% of exchange-held balances — sit on cryptocurrency trading platforms. This means more than half of exchange-held assets are at risk in a mass attack on cryptographic signatures. Such high exposure underscores the need for protocol-level protections that do not depend solely on individual user behavior.
Industry Responds with Funding and Warnings
A strategy-led group has committed $15 million to develop a quantum-resistant Bitcoin network. Meanwhile, Ethereum researcher Justin Drake warned on X that rapid AI progress in mathematics could break ECDSA — the algorithm securing crypto wallets — in months, not years. He advised users to gradually move funds to wallets where public keys are not exposed, arguing AI threats may arrive before practical quantum computers.
Buterin Urges Caution Over Speed
Ethereum cofounder Vitalik Buterin acknowledged the seriousness of AI-accelerated mathematics risks but cautioned against urging users to rush funds to new addresses. He said such haste could cause confusion, errors, or accidental losses, especially without a standardized, trusted framework for executing these moves safely.
