QRAMP addition: Alternative to legacy freeze: “quarantine-mode” legacy spends via two-phase destination commitment

The discussion emphasizes the pressing issue of transitioning Bitcoin addresses to a post-quantum secure format in anticipation of quantum computing advancements. The ideal solution proposed involves an automatic conversion of classic addresses to post-quantum ones on a specified "Q-day," eliminating the need for manual intervention by the owners. This process would ensure that all unspent funds are seamlessly transferred to the new, secure addresses through forced transactions. However, the proposal acknowledges significant practical challenges, such as the requirement for private key sharing, which poses security concerns.

Giulio expresses openness to exploring various solutions to address these challenges and offers support in formalizing a viable approach. He suggests initiating a collaborative project on Overleaf, indicating readiness to assist in developing a detailed plan to transition Bitcoin addresses to a post-quantum secure system efficiently and securely. This proactive stance reflects a commitment to ensuring the long-term security and viability of Bitcoin in the face of emerging quantum computing capabilities.
