Dear Bitcoin Developers,

I am writing to share= my proposal for a new Bitcoin Improvement Proposal (BIP) titled=C2=A0Quantum-Resistant Addre= ss Migration Protocol (QRAMP). The goal of this proposal is to saf= eguard Bitcoin against potential future quantum attacks by enforcing a mand= atory migration period for funds held in legacy Bitcoin addresses (secured = by ECDSA) to quantum-resistant addresses.

The proposal outl= ines:

  • = Reducing Vulnerabilities:=C2=A0Transitioning funds to quantum-resi= stant schemes preemptively to eliminate the risk posed by quantum attacks o= n exposed public keys.
  • Enforcing Timelines:=C2=A0A hard migration deadline that force= s timely action, rather than relying on a gradual, voluntary migration that= might leave many users at risk.
  • Balancing Risks:=C2=A0Weighing the non-trivial risk = of funds being permanently locked against the potential catastrophic impact= of a quantum attack on Bitcoin=E2=80=99s security.

A= dditionally, the proposal addresses common criticisms such as the risk of p= ermanent fund loss, uncertain quantum timelines, and the potential for chai= n splits. It also details backwards compatibility measures, comprehensive s= ecurity considerations, an extensive suite of test cases, and a reference i= mplementation plan that includes script interpreter changes, wallet softwar= e updates, and network monitoring tools.

For your convenien= ce, I have published the full proposal on my GitHub repository. You can rev= iew it at the following link:

Quant= um-Resistant Address Migration Protocol (QRAMP) Proposal on GitHub

<= p style=3D"font-family:Arial,Helvetica,sans-serif;font-size:small;color:rgb= (34,34,34)">I welcome your feedback and suggestions and look forward to eng= aging in a constructive discussion on how best to enhance the security and = resilience of the Bitcoin network in the quantum computing era.

Thank you for your time and consideration.

Best regard= s,

Agustin Cruz
