Europol says crypto wallets vulnerable to quantum attacks, moving funds early is only solution

Europol urged the crypto industry and policymakers to prepare for quantum computing risks, warning cryptocurrency wallets using public and private keys are a key exposure point. It said blockchains’ hash functions and mining structures are relatively safer, but wallets with public keys already exposed on-chain could be hard to protect once attacks begin. Europol cited estimates of 6.04 million bitcoin exposed and flagged technical hurdles in switching to quantum-resistant signatures.

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.
