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.

Quantum attack computation cost estimate on bitcoin, ether drops by more than half in two months

Estimates for the core computation cost of a potential quantum-computer attack targeting bitcoin and ethereum have fallen to less than half of previous levels. The work focused on optimising parts of Shor\'s algorithm used to attack secp256k1, a cryptographic scheme shared by both networks. Researchers stressed this does not mean either system can be cracked with current quantum computers, but the faster-than-expected decline in costs is sharpening calls to bring forward security transitions.

Ethereum Foundation sets Dec 2029 target for quantum resistance across mainnet

The Ethereum Foundation has laid out a roadmap to make the entire Ethereum mainnet quantum-resistant by December 2029. The target is to convert all three layers of Ethereum L1 — execution, consensus and data — to a quantum-resistant structure. The timeline is set on the assumption that a quantum-computing “Q-day” could arrive as early as 2030. Ethereum aims to implement its next major upgrade, Glamssterdam, in December and then deliver full quantum resistance through five further upgrades.
