Holders of Bitcoin and Ether are being advised to evaluate stronger security practices after an Ethereum researcher cautioned that progress in artificial intelligence might eventually pose a risk to the cryptography securing crypto wallets. Justin Drake, an Ethereum researcher, has called on the blockchain sector to methodically prepare for what he terms “bunker mode,” even though no working AI attack has yet been shown capable of cracking Bitcoin or Ethereum wallet keys.
Drake’s cautionary statement centers on the mathematical frameworks used to safeguard private keys. In a worst-case situation, he suggests that advancements in AI-driven mathematics could enable malicious actors to discover shortcuts for recovering private keys from exposed public keys much faster than previously anticipated.
Why AI Could Become a Crypto Security Threat
Digital currency wallets depend on private and public keys to approve transactions. Although public keys are safe to share, private keys must stay confidential because having one grants control over the corresponding funds.
Drake’s worry is that increasingly powerful AI platforms might eventually uncover mathematical vulnerabilities that have eluded humans. In a worst-case scenario, he indicated that the threat could materialize within months rather than years. Nevertheless, this serves as a caution about a potential future development rather than proof that current Bitcoin or Ethereum encryption has been compromised.
This worry comes on the heels of recent showcases where AI models solved increasingly complex mathematical challenges, leading researchers to re-evaluate their beliefs regarding the resilience of standard cryptographic frameworks.
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…

What ‘Bunker Mode’ Means for Crypto Holders
Drake has suggested that major cryptocurrency holders slowly transfer their funds to new addresses where the public keys have never been exposed on the blockchain. This strategy aims to restrict the information available to an attacker if a method to extract private keys from public keys is ever found.
This advice applies especially to older Bitcoin addresses and Ethereum accounts that have already revealed their public keys via previous transactions.
On the other hand, Ethereum co-founder Vitalik Buterin has advised prudence. While acknowledging that AI-related threats to cryptography warrant careful consideration, he cautioned individuals against hastening into mass wallet migrations, noting that errors during the transfer process could lead to independent financial losses.

AI Security Debate Comes Before Quantum Threat
The crypto industry has spent years getting ready for the potential day when quantum computing might break certain cryptographic protocols relied upon by digital currencies. Drake now contends that swift advancements in AI could introduce an additional risk factor.
Artificial intelligence already assists in detecting software bugs. Researchers have shown that sophisticated models can spot flaws in simulated decentralized finance contracts, and security audits aided by AI have likewise exposed weaknesses in crypto software.
Despite this, experts remain split regarding the timeline. At present, no functional AI-based assault has been proven against the cryptography of Bitcoin or Ethereum wallets. Consequently, the discussion centers less on an immediate danger and more on whether blockchain networks need to speed up preparations for a future where more advanced AI tools test existing security baselines.
