Good morning CB,
I have been thinking about CoinSwap for a good while as well.
Here are some very unorganized thoughts.
It wold be nice to interoperate with JoinMarket, i.e. have a JoinMarket maker
that also provides CoinSwap services using the same UTXOs.
However, this requires us to retain

Good morning ZmnSCPxj,
The issues you point out are indeed important to note. Thank you for your
wonderful feedback!

Good morning ZmnSCPxj,
Thank you for your excellent feedback!
Indeed, with a little protocol-level sugar so that the coins being swapped
get paid out of different pubkeys.
I read your article. Excellent idea on the randomized locktimes! I've still

Good morning Germán,
It looks to me like this is CoinSwap with Schnorr Scriptless Scripts.

I also recently put up an article on extending such a protocol across 3 or more
Hello All,
## Objective
* Make atomic swaps within the same chain possible in a traceless way
* Achieving traceless same-chain atomic-swaps effectively turns an entire
chain into a (P2PKH) mixer by default
## Proposed solution
Similar to the way that atomic swaps would work with schnorr
