Hỏi và đáp

When could quantum computers realistically break Bitcoin signatures?

Research suggests a fault‑tolerant device with around 30,000 qubits might do so within an hour, potentially feasible in the early 2030s.

What are Bitcoin developers doing about quantum threats?

Proposals such as BIP 360/361 and a collateral‑based "quantum‑landmine" aim to migrate to post‑quantum signatures and increase attack costs.

Are quantum risks already affecting crypto markets?

Companies like Next Technology are moving Bitcoin holdings and investors cite quantum uncertainty as a factor in reduced institutional interest.
