Hi Jeremy, > Wheres the info come from? Well, multiple places. We could get it from a third party (maybe using anattestation chain of some sort?), or there are certain ways it could beself-referential (like for powswap ). > Now let’s define a threshold oracle – we wouldn’t want to trust just onelousy oracle, so let’s trust M out of N of them! Similar approach is used in discreet log contracts for multi oracles. There is even a project for P2P derivatives but it was not used for any real trades on mainnet or further developed. What difference would OP_CTV make in this project if its implemented in Bitcoin? https://github.com/p2pderivatives/p2pderivatives-client https://github.com/p2pderivatives/p2pderivatives-server https://github.com/p2pderivatives/p2pderivatives-oracle > Does this NEED CTV? No, not in particular. Most of this stuff could be done with online signer server federation between you and counterparty. CTV makes some stuff nicer though, and opens up new possibilities for opening these contracts unilaterally. Nicer? How would unilateral derivatives work because my understanding was that you always need a peer to take the other side of the trade. I wish we could discuss this topic in a trading community with some Bitcoiners that even had some programming knowledge. Derivatives are interesting and less explored or used in Bitcoin projects. They could be useful in solving lot of problems. -- Prayank A3B1 E430 2298 178F
