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.

IBM says quantum computers could handle calculations even billions of supercomputers cannot

An IBM research executive said that once quantum computers reach practical use, they will be able to perform calculations that cannot be handled even by connecting huge numbers of conventional supercomputers. He said quantum computing scales differently, with performance growing exponentially as qubits increase. IBM said hardware advances alone are not enough and researchers must define which problems to solve. Companies are already offering cloud access, and carmakers are testing battery simulations.
