Drake Advocates for “Bunker Mode” in Crypto
Justin Drake, a researcher at the Ethereum Foundation, has called for the blockchain community to adopt what he refers to as “bunker mode.” This involves a strategic movement of assets to new addresses with public keys that have not been previously revealed. He cautioned that advancements in AI could potentially undermine the mathematical security protecting bitcoin and ether wallets within a timeframe of “months, not years.” According to Drake, wallets use a private key—a confidential number—to facilitate transactions, while their corresponding public key enables verification by the network. He expressed concerns that AI technologies might aid in extracting the private key from the public key.
Drake’s concerns are rooted in a recent release by OpenAI of 722 mathematical papers generated by an experimental model analyzed against around 4,000 problems, suggesting that the crypto sector should reevaluate its security timelines in light of AI advancements. While he acknowledged that no concrete attacks on wallet keys for bitcoin or Ethereum have yet emerged, Drake specifically pointed to the elliptic-curve signature algorithm as particularly susceptible to AI-driven vulnerabilities.
Buterin Calls for Caution
Vitalik Buterin, the co-founder of Ethereum, supports Drake’s caution but advises holders to refrain from hasty actions, stating, “I don’t recommend anyone rush to transfer their funds to new wallets today.” Buterin stressed that while the risks are significant, they should not induce panic, adding, “We must take the threats to cryptographic systems from AI-enhanced mathematics seriously.” He further extended his warnings to include lattice-based cryptography, which could also experience “serious challenges” within the next couple of years due to advancements in AI.
Buterin suggested that keeping assets in addresses that have never processed transactions can diminish risks, as the public keys remain obscured behind address hashes. Nonetheless, he cautioned that any mistakes in the movement of assets could lead to losses. Buterin’s response complements Drake’s principal recommendation to transition to new addresses, emphasizing that “a hurried migration could be more detrimental than beneficial,” implying that this should not be treated as an immediate crisis.
Next Steps Forward
Drake proposed that larger and more complex holders commence a gradual transition first, advocating for a methodical approach to prevent errors and minimize losses. He expressed his intention to promote “maximum defensive acceleration” concerning Ethereum’s shift to post-quantum security, insisting that safely moving out of bunker mode would necessitate advancements in “post-AI cryptography.” Drake shared his personal preference for leaning towards “hash-based cryptography” while avoiding structured mathematical assumptions from existing curves, lattices, or isogenies.
“Exiting bunker mode safely will require post-AI cryptography.”
Drake also noted that wallets with less than 50 BTC are partially protected by what he calls “Satoshi’s shield,” referencing “20,000 exposed addresses” associated with Bitcoin’s creator each holding 50 BTC. According to CoinDesk, Bitcoin, which traded around $82,371.15, slipped to around $82,300 but bounced back to approximately $82,800 during Asian trading hours. Meanwhile, the CoinDesk 100 index saw a nearly 2% decline over a 24-hour period as news of Drake’s caution spread.
