Dear Bitcoin Developers,
I would like to propose a Bitcoin Improvement Proposal (BIP) that aims to
introduce quantum-resistant cryptography to the Bitcoin protocol. With the
rapid advancement in quantum computing, this proposal outlines the
integration of post-quantum cryptographic algorithms (SPHINCS+ and
Dilithium) to safeguard Bitcoin=E2=80=99s long-term security.

The key points of the proposal are:
- Introduction of quantum-resistant signature algorithms (SPHINCS+ and
Dilithium).
- New Bech32-based address formats for quantum-resistant addresses.
- Modifications to transaction structures and script opcodes to support
larger signature sizes.
- A transition mechanism through a soft fork to ensure backward
compatibility with existing Bitcoin addresses and transactions.

The full BIP draft is available here
https://github.com/chucrut/bips/blob/master/bip-xxxx.md for your review and
feedback. I look forward to the community's input and am open to
suggestions on how to improve the proposal.

Best regards,
Agust=C3=ADn Cruz
