9-minute attack window, 7,100,000 BTC exposed: how should Bitcoin save itself under the quantum threat
A Bitcoin Security Consortium report states that progress in quantum computing remains gradual, and there is still no cryptographically relevant quantum computer; the risk is concentrated in ECDSA signatures, with about 7,100,000 BTC exposed, and responses include address migration, the post-quantum signature scheme SHRINCS, and P2PK token consensus.
The title mentions a "9-minute attack window," but the body text does not explain what it means.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
The material relays a report on Bitcoin's quantum risk: the potential risk mainly involves ECDSA signatures, and it proposes response directions such as migrating addresses and adopting post-quantum schemes. The text also states that there is currently no cryptographically relevant quantum computer, so the exposure described is a potential risk and does not mean an attack has already occurred.
Why it matters to readers
If the security of the relevant signatures is threatened by quantum computing, it could affect the security of Bitcoin assets; however, the material contains no evidence that an attack has occurred, nor does it explain how the exposure estimate was calculated.
This is a potential security risk that requires continued attention; it does not mean that a quantum computer can currently steal these BTC. Pay attention to the original report, the basis for the risk estimate, and discussion in the Bitcoin community about migration and quantum-resistant schemes.
Risks and unknowns
The material does not provide the original report or the method for estimating the exposure of about 7,100,000 BTC.
The "9-minute attack window" in the title is not explained in the body text.
The material does not explain the specific implementation status or degree of adoption of address migration, SHRINCS, or P2PK token consensus.
It cannot be confirmed from the material when quantum computing will break the relevant cryptographic technology or what its actual capability is.
