Dear Bitcoin Developers,
I am writing to share my proposal for a new Bitcoin Improvement Proposal=20
(BIP) titled *Quantum-Resistant Address Migration Protocol (QRAMP)*. The=20
goal of this proposal is to safeguard Bitcoin against potential future=20
quantum attacks by enforcing a mandatory migration period for funds held in=
=20
legacy Bitcoin addresses (secured by ECDSA) to quantum-resistant addresses.
The proposal outlines:
- *Reducing Vulnerabilities:* Transitioning funds to quantum-resistant=
=20
schemes preemptively to eliminate the risk posed by quantum attacks on=
=20
exposed public keys.
- *Enforcing Timelines:* A hard migration deadline that forces timely=20
action, rather than relying on a gradual, voluntary migration that might=
=20
leave many users at risk.
- *Balancing Risks:* Weighing the non-trivial risk of funds being=20
permanently locked against the potential catastrophic impact of a quantu=
m=20
attack on Bitcoin=E2=80=99s security.
Additionally, the proposal addresses common criticisms such as the risk of=
=20
permanent fund loss, uncertain quantum timelines, and the potential for=20
chain splits. It also details backwards compatibility measures,=20
comprehensive security considerations, an extensive suite of test cases,=20
and a reference implementation plan that includes script interpreter=20
changes, wallet software updates, and network monitoring tools.
For your convenience, I have published the full proposal on my GitHub=20
repository. You can review it at the following link:
Quantum-Resistant Address Migration Protocol (QRAMP) Proposal on GitHub=20
<https://github.com/chucrut/bips/blob/master/bip-xxxxx.md>
I welcome your feedback and suggestions and look forward to engaging in a=
=20
constructive discussion on how best to enhance the security and resilience=
=20
of the Bitcoin network in the quantum computing era.
Thank you for your time and consideration.
Best regards,
Agustin Cruz
