Beulah’s story is a great example of what Bitcoin open-source funding should look like: fund the person doing the hard, foundational work—not just the flashy product.
Nested MuSig2 is the kind of work most users will never see, but they can benefit from its consequences: stronger key management, distributed signing, fewer single points of failure, and privacy-preserving multisig constructions. The fact that the implementation is going into secp256k1-zkp means the work can become infrastructure that everyone can build on, not proprietary code locked inside one company.

And I love the path: self-study → real contributions → mentorship → proof of work → funding.
That's the flywheel.
