TL;DR
- Ethereum researcher Justin Drake urged crypto holders to prepare for a possible ECDSA break, while stressing that current cryptography remains secure.
- He recommends moving large holdings to fresh addresses whose public keys have never been exposed through signed transactions.
- Drake links the risk to advances in quantum computing and AI-driven mathematics, while pointing toward hash-based cryptography as a stronger long-term defense.
Ethereum researcher Justin Drake has urged crypto holders to enter what he calls “bunker mode” planning against a potential failure of ECDSA, the cryptographic system securing transactions across major blockchain networks. Drake stressed that the technology has not been broken, but argued that preparation is becoming reasonable as advances in computing and artificial intelligence accelerate.
Drake’s warning focuses on the Elliptic Curve Digital Signature Algorithm, or ECDSA, which Bitcoin and other crypto networks use to verify that transactions have been authorized by the owner of a private key. If an attacker could efficiently reverse that system, exposed public keys could potentially put funds at risk by enabling private-key recovery.
Today I call upon the blockchain industry to calmly begin planning for “bunker mode”. My personal recommendation is to set in motion a controlled mass migration of assets to fresh addresses, i.e. addresses whose pubkeys remain hidden behind a hash.
Holders, starting with large…

Ethereum ECDSA Risks Push Holders Toward Fresh Addresses
Drake recommends that large and sophisticated crypto holders move most assets into fresh addresses that have never signed a transaction. The reasoning is straightforward. Once an address signs a transaction, its public key can become visible, potentially giving a future attacker more information to work with.
He also advised users to move remaining funds after an address has been used, rather than assuming that only newly transferred assets require protection. Drake emphasized that these measures represent personal recommendations, not evidence that ECDSA is currently vulnerable.
The researcher also called on major exchanges and stablecoin issuers, including Binance, Bitbank, Robinhood, Bitfinex and Tether, to consider stronger safeguards for cold-storage holdings. He referenced Project Eleven’s Bitcoin Risq List, which tracks addresses with exposed public keys.
For smaller Bitcoin holders, Drake noted that the difficulty of targeting the largest exposed wallets could provide an indirect layer of protection. He cited thousands of addresses associated with Bitcoin creator Satoshi Nakamoto that hold 50 BTC each as an example of potentially more attractive targets for attackers.
AI, Quantum Computing And The Next Cryptographic Upgrade
Drake connected his concerns to advances in AI-generated mathematics, including a recent publication of hundreds of mathematical manuscripts produced by an AI model. He argues that increasingly capable AI systems could discover mathematical techniques that challenge assumptions behind elliptic-curve cryptography.
Quantum computing remains another major concern. “Q-day” refers to the point when quantum machines become capable of breaking widely used public-key cryptography at practical speeds. Drake said the worst-case scenario could arrive in “months not years,” although this remains a risk assessment rather than a confirmed timeline.
