Ethereum researcher warns AI may break ECDSA before quantum computers, urges \'bunker mode\' planning
Justin Drake of the Ethereum Foundation warned that the ECDSA signature system used by Bitcoin and Ethereum could be broken by AI before quantum computers reach “Q-day”. He urged the blockchain industry to plan for “bunker mode” and recommended a controlled mass migration of assets to fresh addresses whose public keys remain hidden behind a hash. He said holders should not rush or panic and urged major firms to harden cold storage.

Quantum computers could neutralise bitcoin? No basis for it within 10 years
Concerns are resurfacing that quantum computers could break bitcoin\'s cryptographic system, but an analysis says it is hard to view that as a realistic threat at current technology levels. It says there is little basis to expect a cryptographically meaningful quantum computer within the next 10 years, and it remains uncertain whether such equipment can be developed. The analysis adds that bitcoin should still continue research into post-quantum cryptography.

Post-quantum security tech emerges without changing crypto wallet addresses
A new security technology has been proposed that aims to prepare for future quantum-computer attacks without changing addresses or moving assets in existing cryptocurrency wallets. Blockchain security firm American Fortress 공개ed an encryption structure that adds post-quantum protection while keeping ECC-based wallets for Bitcoin, Ethereum and Solana. The paper says it is compatible with HD wallets but has not been peer reviewed. Rival efforts include Freedom Factory’s PQ1 post-quantum hardware wallet for EVM networks.
