Accelerating Post-Quantum (PQC) Readiness: A Call for a Concrete Roadmap #34964

@HToTH

Please describe the feature you'd like to see added.

The recent Google Research blog serves as a critical wake-up call for the Bitcoin community.

While the "Q-Day" might still be years away, the research highlights a more immediate danger: the extreme difficulty of implementing quantum-resistant schemes responsibly. The discovery of vulnerabilities in early PQC attempts (like the WOTS case mentioned) proves that we cannot afford a rushed, last-minute migration.

I propose that the community moves beyond abstract discussions and begins formalizing a concrete PQC Roadmap:

From Theory to Spec: We need to transition from "discussing algorithms" to drafting specific BIPs for PQC-compatible signature schemes (e.g., ML-DSA or SLH-DSA).

The "Harvest Now, Decrypt Later" Threat: This is already happening. Long-term storage security depends on actions we take today, not tomorrow.

Implementation Safety: We need to establish a dedicated working group to audit potential PQC implementations to avoid the pitfalls Google identified.

"Wait and see" is no longer a security strategy. We need to treat PQC migration as a high-priority engineering goal to ensure Bitcoin's long-term value-store proposition remains intact.
