Hi Chris,

This is a really exciting effort. I hope I will be able to contribute to
it. I was wondering if you had seen the idea that DLCs can be done in only
two transaction using Schnorr[1]. I also think this can be done in Bitcoin
as it is today using ECDSA adaptor signatures [2]. In my mind, the adaptor
signature protocol is both easier to specify and implement on top of being
cheaper and more private.
