                Basic payjoin/p2ep protocol for Joinmarket wallets
              
          

        

      

        

  

      

    
Described here is a variant of what has previously been published
under the name "P2EP" or Pay-to-endpoint, in which A pays B but B contributes utxos, i.e. it's a coinjoin-payment.


I'm using the term "payjoin" here to refer to using that idea, but not including a URI/endpoint specific to B, and
not allowing (as a merchant would) arbitrary payments, which opens up certain problems around snooping attackers
(more on this below).
So payjoin just means "A pays B but B actively participates and passes across utxos as extra inputs".


I'll defer a more features-focused and non-tech friendly description of what this means to a later blogpost.

Actual TPS of Bitcoin


Counting on-chain transactions alone to illustrate pretty much anything is wrong. One should take into account at least TX batching.


A possibly better way is to calculate based on new UTXOs created excluding the change outputs.


Doing rough calculations, we assume the worst case of every TX having a change output, so the results are the most pessimistic version and actual numbers are better.

Explanation of how using Schnorr signatures, we can achieve an atomic swap of the "scriptless script" style.


This is based on Poelstra's ideas as summarised in https://download.wpsoftware.net/bitcoin/wizardry/mw-slides/2017-05-milan-meetup/slides.pdf ; also see the earlier outline in https://lists.launchpad.net/mimblewimble/msg00086.html.


Note that the details here are just my thoughts, so if you come to this randomly, don't take it as some kind of well established protocol!


Preliminaries:


We'll use || for concatenation and capitals for elliptic curve points and lower case letters for scalars.
