Hi Agustin,
Good to see!

Dear Bitcoin Developers,=20
I would like to propose a Bitcoin Improvement Proposal (BIP) that aims to=
=20
introduce quantum-resistant cryptography to the Bitcoin protocol. With the=
=20
rapid advancement in quantum computing, this proposal outlines the=20
integration of post-quantum cryptographic algorithms (SPHINCS+ and=20
Dilithium) to safeguard Bitcoin=E2=80=99s long-term security.
=20
The key points of the proposal are:=20
- Introduction of quantum-resistant signature algorithms (SPHINCS+ and=20
Dilithium).=20
- New Bech32-based address formats for quantum-resistant addresses.=20
- Modifications to transaction structures and script opcodes to support=20
larger signature sizes.=20
- A transition mechanism through a soft fork to ensure backward=20
compatibility with existing Bitcoin addresses and transactions.=20
The full BIP draft is available here=20
https://github.com/chucrut/bips/blob/master/bip-xxxx.md for your review and=
=20
feedback. I look forward to the community's input and am open to=20
suggestions on how to improve the proposal.=20
Best regards,
Agust=C3=ADn Cruz
