Proposal for Quantum-Resistant Address Migration Protocol (QRAMP) BIP

In a recent exchange on the Bitcoin Development Mailing List, a robust discussion unfolded around the implementation of a forced migration mechanism to ensure the security of Bitcoin funds against quantum computing threats. The proposed mechanism centers on setting a clear and unambiguous deadline, identified by a specific block height, after which any funds stored in quantum-unsafe addresses would become unspendable. This approach aims to mitigate complexity and potential vulnerabilities that could arise from transitional transaction types, offering a straightforward solution to secure Bitcoin's blockchain against quantum adversaries.

The rationale behind advocating for a forced migration lies in its ability to provide a definitive resolution to the threat posed by quantum computing. By eliminating the possibility of spending non-quantum-safe funds beyond the set deadline, the mechanism seeks to prevent the exploitation of lost or inactive wallets, including those potentially belonging to early Bitcoin contributors such as Satoshi Nakamoto. The concern is that, without such a measure, quantum hackers could eventually access these dormant funds, reintroduce them into circulation, and thereby trigger a catastrophic market shock. Through the implementation of a forced migration, the proposal aims to preempt any such scenarios, ensuring the long-term security and stability of the Bitcoin network by making only quantum-safe funds spendable post-deadline.
