Spent the morning building this out with @DennisReimann.

In my third Mempool Observation, I describe and use a methodology to identify Blockchain wallet transactions, derive wallet-usage insights, and discuss potential wallet privacy improvements.

As of this merge, Joinmarket is using python-bitcointx as its bitcoin code backend, supports PSBT and BIP78 Payjoin (well, I tested it with real coins against btcpayserver so .. I think so!) and even has some (currently not activated) SNICKER code.

Heads up that this is a "breaking" change in that if you pull from master you will need to rerun the installation script.

#bitcoin #joinmarket

So BIP78 has been merged (no, don't ask me what that means!) and even has a test vector:

It's interesting how much debate there was about tiny subtleties of fee choice and restriction, and what each side checks - even the most trivial 2 party protocol can be hugely complex with interactivity.

Optech 102 ( talks a bit about WabiSabi.
I did spend some time analysing this crypto construction (at the prompting of @nothingmuch and others) but I mostly ended up getting lost in years-old crypto papers (and even finding an error in a 2013 paper security proof) and never really fully analysed the actual idea before getting sidetracked with a million other things ...
Anyway it's a very cool if rather sophisticated idea! Give it a read.

#crypto #bitcoin #coinjoin

A 0.6.3 release for Joinmarket is imminent, which will be the *last release supporting Python 3.5*.

(next will be py3.6 and above, only, and will be a big change including psbt and other stuff)

Please run the current commit, if you have a chance, to sanity check if there are any final bugs to fix:

@fiatjaf Following up on this after two weeks of use: Fraidycat is great! This is the way I want to follow everyone and everything going forward. One feature I've come to especially appreciate is being able to partition certain people into the Occasional or Sometimes categories---e.g. people who I generally like and want to keep track of but whose political opinions or other content annoys me if I have to see it too often.

Thanks again for the recommendation!
