CoinJoin: Bitcoin privacy for the real world

[Nicolas Dorier]

Wasabi Wallet have been an awesome driver for making Bitcoin privacy accessible to non technical people.
IMHO, they definitively deserve to have a bounty.

nopara73 is such awesome contributor to Bitcoin ecosystem.

I've got a reaction from theymos https://www.reddit.com/r/Bitcoin/comments/b8xgz7/nopara73_reapplies_for_the_46_btc_bounty_for_his/ek95nbo/

So hopefully at least parts of the bounty are put to good use this time.
nopara73 deserves a large part of it in my opinion.

I'll quote Theymos' reply here:

We've been discussing whether wasabi/joinmarket deserve some of the bounty. Personally, I think that wasabi does deserve some of the bounty.

Code:

He definitely deserves a large portion of the bounty. Wasabi is such an awesome wallet and service.

[bitkapp]

Agreed. Wasabi deserves the bounty.

[TheBeardedBaby]

When we gonna know what happen with the bounty?  I also vote for Wasabi, if it will make any difference at all.
Very nice and clean design, I tried it only once just for test and I really liked it.

[TheNewAnon135246]

Would be nice to get a response here from Theymos (since he posted about it on Reddit).

I understand that the devs at Samourai can sometimes exaggerate their claims due excitement but they appear to be doing great work to make Coinjoin usable along with nopara - https://twitter.com/SamouraiWallet/status/1120215932922679297

IMHO they deserve some recognition and part of the reward as well, because bringing coinjoin to mobile in a great UX is an amazing achievement.



Samourai implements ZeroLink with whirlpool

Zerolink uses Chaumian CoinJoin to mix coins

For the record I don't have any association with Samourai. Back then I wanted to build Wasabi Wallet for Samourai, but they were not interested/responding my messages and nagging, so I went ahead alone.

Is Wasabi going to be more linux friendly in the future?  Like for open source builds, etc?

Relying/trusting .NET SDK from Windows to build on top of is a major drawback to good OS crypto projects.

[nopara73]

Wasabi is built with .NET Core. Core is open source and cross platform, so I am not sure what you mean.

[Carlton Banks]

Wasabi is built with .NET Core. Core is open source and cross platform

it wouldn't surprise me if the .NET framework is an epicly gigantic codebase that no one person could be reasonably expected to read and review, like 100's of thousands of LOC.

So there's not much point in saying "open source baby", the Game of Thrones books are open source and I'm still not going to read them. And more importantly, is the byte-code interpreter open source?

When you're dealing with a product from an organisation with such a bad reputation as that of Microsoft, the questions are endless, and the answers are likely to be unsatisfactory. I don't want to waste my time.


(not to mention, Microsoft are now openly collecting all user data from their Windows users, what's the point in developing privacy software for an OS that openly exploits user privacy, why even bother?)

.NET Core is not .NET Framework. The former is cross platform the latter is Windows only. Yes, they are both open source and yes, the Roslyn compiler is open source, too. In fact I managed to contribute to the .NET ecosystem once or twice in the past, too. Please don't make comments like this when you have no knowledge of the subject.

Regarding your ad hominems on Microsoft, I believe they are worthy topics to discuss, but falls outside the scope of this discussion.

you can't pretend Microsoft have a good reputation, or that Windows doesn't openly suck up all user data, it's a default option in Windows, labelled "Please spy on everything I do on this computer"

so why even try to defend them? why attack someone who's only informing people about platforms with zero privacy, Mr. Privacy?

I don't endorse Microsoft's data collection policies. Quite the contrary, in fact, I've raised my voice against them in the past and received concerning response from MS: https://github.com/dotnet/cli/issues/10497

But again, it falls outside the scope of this discussion.

[Carlton Banks]

so tell us again about "ad hominems on Microsoft"

[DaCryptoRaccoon]

Wassabi wallet get's a vote from me. 
Must praise nopara73 for the work on the wallet have been testing out on ubuntu and quite impressed with the project and wallet thus far,

I agree with what is being said about the .NET privacy issue as nopara73 pointed out he is aware of the situation as are many others regarding the telemetry/privacy issues in the .NET framework.

You sir deserve some bounty!

Repeated dishonesty from Samourai have barred them from ever receiving a payout from the bounty as far as I am concerned: I will not be signing a transaction paying them. Evaluating the privacy of systems is difficult even when the involved parties are honest and easy to work with, it is far too difficult when they are actively misleading.  Personally, I would urge my friends to not use that wallet.

As far as other stuff, there has been efforts in progress to do some awarding for a couple months now. It takes time to evaluate things and work with the recipients.  If it didn't this bounty would have been gone years ago when "darkwallet" demanded the whole thing then mobbed us with unreasonable demands (including public campaigning which was vigorous to the point of harassment) to pay it all to them when the result didn't provide the advertised privacy and didn't even stay available due to the operating model.
