Fastest way to coinjoin on Mac

[clay-v]

Payout: 750k sats (0.0075 btc)

Guide file

We'd like a guide on the fastest way to make a first coinjoin on a desktop. We'd like to have the user to be able to go from zero to be able to make a payment in Joinmarket in the fastest way possible.

1. Install Virtual Box
   01 Ubuntu Node Box - Ubuntu Virtual Machine & Familiarisation

• Optimize for minimum requirements necessary in terms of storage, ram and cpu

2. Install Joininbox - it was brought to my attention by @openoms that Joininbox can do a lot of the hevy lifting and can work on Debian / Ubuntu Linux VM as well.

• Download and verify signature
• Edit joinmarket.cfg
• Tumbler
• Single coinjoin
  12 Ubuntu Node Box - JoinMarket

Hi I would like to take this, does it assume any prior knowledge from the user?

[clay-v]

Hello, @keblek. I think it's fair to assume that the user has btc and wants to spend them privately. So they may have coins on an exchange or other wallet and want to setup a private way to spend it. They have at least superficial knowledge of using btc.
I've also updated the description to have Joininbox do most of the heavy lifting.

[keblek]

Ok great, what do you think about this as the fastest way to get Core and Tor running on a Mac? https://github.com/BlockchainCommons/GordianServer-macOS

[keblek]

you can also purchase it from the mac app store, which I know is not very cypherpunk but is a very easy way to get all that running on your mac

[keblek]

also can you change the denomination of the contract to btc?

[clay-v]

I've updated the description to have Joininbox do most of the heavy lifting (Tor, Bitcoin Core and Joinmarket). So please have that in mind.

I'm not familiar with the above project but I do think a watch-only wallet from where the user can generate invoices and monitor their funds may be necessary. For that I was thinking of Wasabi wallet because it comes packaged with Tor.

also can you change the denomination of the contract to btc?

Please clarify this.

[keblek]

oh ok so the user has to already have joinmarket, core and everything already running?

I thought the description implied starting from cold with no software running.

Running joininbox would need to be virtualized somehow which brings its own fun game with it. If possible I would say this would be made the best using a package manager, in this case brew, and running as much as possible on macOS.

The wasabi wallet is actually a really good idea as well.

With regards to the denomination, if number goes up I get less bitcoin. If the contract instead is in btc, then no matter what I always get the same amount of sats.

No. The user would need to:

1. install a VirtualBox
2. install Joininbox in the virtual machine (it bundles togetther Tor, Bitcoin Core and Joinmarket)

With regards to the denomination, if number goes up I get less bitcoin. If the contract instead is in btc, then no matter what I always get the same amount of sats.

Ok, I thought you were referring to denominations on the sofware. I'll commit to an exchange rate of 40k BTC/USD. So 750k sats (0.0075 btc)

[keblek]

nice!

[keblek]

yea so virtualbox is incredibly buggy on macs, would the guide be acceptable if we could use parallels (not FOSS)?

[openoms]

@keblek I would stay away from recommending any non-open source software for this purpose.
VMware should work better maybe together with Vagrant.

That's why I asked, I don't want to use it but every year year somebody is going to have to update the guide for how to work around these issues since they always come up after every update.

The scope of the guide is maybe too broad, maybe we can look into just showing how to get the taker to run which should be much simpler. I don't see the benefit in adding how to run maker since if you want to do that you should run it on a linux server.

That's just my opinion.

[openoms]

@keblek to get to running the Yield Generator from the command line have a look at https://www.keepitsimplebitcoin.com/joinmarket/

[clay-v]

Indeed, this guide is aimed only at makers.

[keblek]

oh that's good to know.

I am under the impression that JM lacks takers though, since fees are so low. Am I correct?

[clay-v]

I think that's a fair statement, but that isn't a negative.

[keblek]

alright so at this point I am pretty much done trying to get virtual box running - it doesn't work on the latest version of macos.

It crashes when I try to add a new ISO.

TBH vb has never been a stable or quality piece of software on macOS and I doubt anyone on mac would be willing to put up with all this trouble.

I tried using vagrant which does work but I can't get a GUI.

installing vagrant and virtualbox is something I could write up for a tutorial

Would this suffice to claim the bounty? terminal only (in a way that works quite reliably) with no GUI

[clay-v]

That's not great but get a working workflow and maybe later we other MacOS users can opine on how to fine tune it.
