Hi all,

Did someone say rust-dlc? Just kidding, but wanted to mention that indeed
it's under active development, supports multi oracle contracts and many
other cool things (pretty much everything you can find in the dlc specs)!

Otherwise nice article Jeremy. Maybe you should drop by our monthly DLC
spec meeting one of these days. I'm sure everybody would be happy to hear
how we could improve the Bitcoin derivatives ecosystem with CTV and what
infrastructures or code could be reused from DLCs.

Cheers,

Thibaut

Prayank,

I believe the p2pderivatives DLC application is still under active 
development here (single oracle):

https://github.com/p2pderivatives/rust-dlc

I was once involved in the project in a galaxy far far away but haven't 
kept up with the project.  Also, I'm a few days behind in the Bitcoin 
Advent Calendar :)


Cheers,

Now let’s define a threshold oracle – we wouldn’t want to

trust just one lousy 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-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.

A core benefit is unilateral opens. I.e. you can pay someone into a
derivative without them being online.


For example, you want to receive your payment in a Bitcoin backed Magnesium
risk reversal in exchange for some phys magnesium. I can create the
contract with your signing keys offline.

I have a decent understanding of a bit of the trading world and can answer
most questions you have, or point you to someone else who would.


The way a unilateral option would work is that I can create a payment to
you paying you into an Option expiring next week that gives you the right
to purchase from me a magnesium risk reversal contract that settles next
month.



An example where this type of pattern must be used is in conjunction with
DCFMP and PowSwap where miners could commit to, instead of just keys,
'trade specs' and an Automatic market maker inside the DCFMP could attempt
to match that miner to a counterparty who wants the opposite hashrate
hedge. The need to exchange signatures would make this unviable otherwise.
