BOUNTY: Build Web UI

[testthewatter]

I'd like to offer up a bounty for someone to build a Web UI. See below for bounty amount, currently over .4btc.

This enhancement will allow JoinMarket to be included as an application for the more user friendly node packages such as Umbrel. As these node deployments are used by many convicted, but less technical bitcoiners, this enhancement should, in theory, increase the market size for CJ yield generation & raise the floor of privacy preservation across the network.

There are two people actively working on an extension to #670, which distinct from the existing proof of concept repo https://github.com/Joinmarket-Org/jmcontrolcenter , is using react rather than Angular. That should appear on github shortly.

If anyone wants to collaborate on this I am willing to tackle this bounty.
I have expirence with React so this would be my preffered technology to work on this.

[kristapsk]

I could help with this, but guess first we need to wait on @AdamISZ mentioned extension to #670.

[pedromvpg]

Would be it helpful to work out a design a figma interactive prototype to discuss the interface and experience before committing to code?

[undeath]

Would be it helpful to work out a design

That's a fair question. UX is an area where joinmarket can definitely be improved.

Furthermore, defining a minimum feature set for the Web UI would be helpful, especially wrt bounties. I guess wallet and taker functionality is a must (basically what Qt can do right now). What about maker functionality?

[AdamISZ]

Many points of reference may be helpful. First, w.r.t. the idea of a feature set, that's a great idea, if someone does that you might find the list 1-10 in this gist a useful starting point(?): https://gist.githubusercontent.com/AdamISZ/f062c7453c6973a8287897fe506b9d19/raw/0569de16cecf455fdf0fc2006c6c25e1e68cc1cd/API-Joinmarket

Second, #670, which implemented a rudimentary JSON-RPC API, but didn't yet have any session management, shouldn't be a blocker to anyone nor the existing repo https://github.com/Joinmarket-Org/jmcontrolcenter, in which there was a working implementiontation of unlock-view wallet-start and stop maker service and a couple other things. People can feel free to reuse them, build on them, ignore them, whatever works.

Third I want to shoutout at this point the "Summer of Bitcoin" participants @shobhitaa and @abhishek0405 who have started working on a new PoC implementation in React (they already have session management with JWT), using essentially the same backend as in #670. (I've been mentoring them). See https://github.com/shobhitaa/Joinmarket-SOB and https://github.com/abhishek0405/joinmarket-clientserver/tree/rpc-api-2 .

[AdamISZ]

If anyone is interested in gory details, one thing that I think is tricky: implemented taker-side coinjoin (or indeed tumbler) seems a little bit trickier than any other feature to add, because of the server needing to "push" the outcome of the first round of communication with participants (the Taker callback filter_order_callback, which gets the client's acceptance of the join conditions). Websockets are one way to approach that, perhaps some other subscribe architecture, or perhaps something else.

On the more positive side, my original experiments suggest to me that pretty much everything else is not tricky (because the heavy lifting is already assumed to exist in the backend).

Incredible. From those of us who have no clue how to build this: Thank you!

[modl21]

to be clear this is not an umbrel specific bounty, the result should be FOSS so other node projects can implement it as well
