I'm not sure how deep I've seen a write up go. I'd expect a write up on Frost to be more readily available, and then the info on frostr.org to understand where it's different, and where there are things that may not have quite been mapped over, such as tools for distributed key generation.
Such as this one: https://eprint.iacr.org/2020/852.pdf
It's basically an application of Shamir's secret sharing which conceivably can be used both on the nsec and an xpriv.
I've been doing more chatting with AI about it and other nested key variants to understand differences. Some of those actually do seem better for just Bitcoin but Frost seems to hit the sweet spot of working well for both Nostr and Bitcoin.
That all said, I'm no cryptographer, just really curious about what can be done, with a penchant for bringing up ideas like this hoping someone who does know what they're doing might run with them.
