    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.

    Usually the issue tracker is used to track technical issues related to the Bitcoin Core code base.

    General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange or the #bitcoin IRC channel on Libera Chat, or one of the Bitcoin subreddits, or any other place that you feel is well suited.

    Network-wide consensus and/or P2P changes first need to be discussed with the greater ecosystem, for example https://groups.google.com/g/bitcoindev, or https://delvingbitcoin.org/. Also, they need a BIP to be implemented in Bitcoin Core and other software that connects to the bitcoin P2P network.
