- Public‑Key Exposure
- 35.4% of Bitcoin supply now has visible public keys, reviving quantum‑security debate (Nov 2026)
- Developer Proposal
- Cory Fields suggests a collateral‑based "quantum‑landmine" to make quantum theft costly (Nov 2026)
- Corporate Action
- Next Technology plans to sell or pledge its 5,833 BTC treasury citing quantum risk (Oct 2026)

问答
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.
