Hi List,

We now have have some working = code for executing 2-outcome Discreet Log Contracts as well as=C2=A0documentation on = how to use it, and would love if anyone wanted to try it out!
Here's a short blog post with a video demo of an execution.=

Hi Chris,=C2=A0

This is a really exciting = effort. I hope I will be able to contribute to it. I was wondering if you h= ad seen the idea that DLCs can be done in only two transaction using Schnor= r[1]. I also think this can be done in Bitcoin as it is today using ECDSA a= daptor signatures [2]. In my mind, the adaptor signature protocol is both e= asier to specify=C2=A0and implement on top of being cheaper and more privat= e.

Hi all,=


Suredbits and Crypto Garage have begun to work on a specification for = using discreet log contracts in a safe, private = and interoperable way. We are writing to the mailing list to inform and sol= icit feedback for the protocol specification so that we can -- as a communi= ty -- 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 Pr= oposals) and BOLTs (Basis of Lightning Technology) so that others that wish= to use the technology can easily write software to integrate into the prot= ocol.


A secondary goal of ours is to remain compatible with standards u= sed by other bitcoin related protocols (like Lightning) so that every futur= e bitcoin related protocol can reach for a =E2=80=9Ctoolbox=E2=80=9D of agr= eed standards for things like funding transactions and closing transactions= . We want to avoid reinventing the wheel where possible and allow for libra= ry developers to re-use software to hook into many bitcoin related protocol= s.=C2=A0
