Hi Chris,=C2=A0

This is a really exciti= ng effort. I hope I will be able to contribute to it. I was wondering if yo= u had seen the idea that DLCs can be done in only two transaction using Sch= norr[1]. I also think this can be done in Bitcoin as it is today using ECDS= A adaptor signatures [2]. In my mind, the adaptor signature protocol is bot= h easier to specify=C2=A0and implement on top of being cheaper and more pri= vate.

Hi all,


Suredbits and Crypto Garage have begun to work on a specification for us= ing discreet log contracts in a safe, private a= nd interoperable way. We are writing to the mailing list to inform and soli= cit feedback for the protocol specification so that we can -- as a communit= y -- agree on a common standard to use Bitcoin oracles.=C2=A0

Our goal = is to end up with a set of documents like the BIPs (Bitcoin Improvement Pro= posals) and BOLTs (Basis of Lightning Technology) so that others that wish = to use the technology can easily write software to integrate into the proto= col.


A secondary goal of ours is to remain compatible with standards us= ed by other bitcoin related protocols (like Lightning) so that every future= bitcoin related protocol can reach for a =E2=80=9Ctoolbox=E2=80=9D of agre= ed standards for things like funding transactions and closing transactions.= We want to avoid reinventing the wheel where possible and allow for librar= y developers to re-use software to hook into many bitcoin related protocols= .=C2=A0
