After all, Bitcoin is here to set us free from the heavy chains of our current monetary system.
But that's exactly what you are not supposed to be in their eyes. That's why there is so much focus on destroying what Bitcoin is and it has nothing to do with stopping criminals, pedophiles, and whatnot. It's about stopping all of us using and trusting something out of their reach. It's the same as with the POW mining objectors. It's not about having people move to clean energy sources or incentivizing them to do so, it's about attacking a core feature of Bitcoin in an attempt to give it a hard hit that would be difficult to recover from.

By what method to these companies determine which coins are tainted? Are their methods audited for accuracy?  Why are they trusted?  Does Wasabi Wallet do their own chain analysis?
Mind boggling.  Even if local authorities did the investigation instead of whoever Wasabi is working with, how many times has the wrong person been called a criminal and thrown in jail for doing nothing wrong?  On the other hand, how many of the real criminals got a pass and never been put in jail just because they were wealthy and powerful, just because they bribed the right party?

Why would Blockchain Analysis be ANY different if this is happening at the highest levels with authorities, politicians and everyone else involved?

Look, maybe if there was a way to stop all crimes with 100% accuracy I would support it.  Hell, put it straight on top of Bitcoin's blockchain if that is the case.  But if we are talking about freedom and censorship free, there is no way we can start censoring Bitcoin users and transactions based on guessing and investigations with who the heck knows how much accuracy and still call it censorship free because that is so contradictory and then Bitcoin becomes useless really.

If I get to be treated as a criminal and wrongfully censored for my actions then why the hell would I even use Bitcoin at all when I have banks that under some conditions are faster and even cheaper than Bitcoin is.  They can censor me, they can question me.  I sure do know they can.  And at least I then know who I am talking to and what I put myself into rather than finding myself in a situation where I can not move money around due to a stranger telling another stranger that I am not a good guy.

After all, Bitcoin is here to set us free from the heavy chains of our current monetary system.  We are a community of people who supposedly and theoretically want just that, if we exclude the speculative investors.  I do not mind Bitcoin sitting at $20,000 for the next 20 years.  I just want it to offer me the same freedom it did so far.

But do not try making me accept that censorship should be part of a censorship free system because that immediately shows me what your intentions are and never in this life will I agree censorship is fair or works against crime.  Because at about any given time in history we know that a little censorship always led to more censorship and then ultimately led to some of the worst rules, regimes and choices that were definitely not for the people but against it.

There's nothing stopping anyone from spinning up their own blockchain analysis service and charging extortionate rates to tell other people where you think coins have come from based on complete guesswork.
I can do that for free Cheesy Here's a list of all taint free Bitcoin addresses! I can evey share how I came to this conclusion. It's quite simple: 1BTC=1BTC Smiley

Are their methods audited for accuracy?
Just to add to witcher_sense's good answer above: The methods aren't audited because their methods aren't even known. Most of these services will just take an address one of their paying customers feed them, and then return some breakdown of the percentage of coins from various places, such as centralized exchanges, DEXs, casinos, scams, etc., with absolutely no information about how they reached that conclusion, and then their customers will treat that as gospel. There's nothing stopping anyone from spinning up their own blockchain analysis service and charging extortionate rates to tell other people where you think coins have come from based on complete guesswork. And as we regularly see, they often get things wildly wrong.

There was a post I made a few months ago about how one such service shows that large amounts of coins in the hot wallet of large centralized exchanges are "tainted": https://bitcointalksearch.org/topic/m.59905002

What is chain analysis?
It is when individuals or companies take advantage of the fact that blockchain is fully transparent, trying to figure out and subjectively interpret what is occurring inside it.

Quote
I searched multiple engines and two common results are companies selling a service.
Yeah, some companies make money selling their subjective interpretation of what's happening to other companies, exchanges, law enforcement agencies, governments, dictators, and also surveillance-oriented wallets like Wasabi Wallet.

Quote
One of the companies claims to be building trust in blockchains lolz. The blockchain is already trusted that's the point. 
This one is a ridiculous claim that they employ to siphon money off from people who naively believe surveillance companies provide valuable services and actually know what's going on.

Quote
By what method to these companies determine which coins are tainted?
The point is they do not "determine", they gave themselves the power to unilaterally decide which coins are to be deemed clean and which aren't.

Quote
Are their methods audited for accuracy? 
How would you audit subjective interpretations?

Does Wasabi Wallet do their own chain analysis? 
Of course, they do, how else can they determine that some inputs came from Wasabi 1.0 or that particular UTXO has a particular anonymity set if not by looking at analyzing blockchain data?

Despite the fact that Wasabi 2.0 made CoinJoins more affordable for the average user (one no longer needs 0.1 btc to participate) , the volume of mixed bitcoins continues dropping steadily.
Note that the same site also reports a decrease in volume for Samourai and JoinMarket for the last week, though. Not sure if it's a problem with their data or due to the market conditions, but I don't think we can take this as evidence of falling Wasabi volume.

But I came to a different conclusion, namely, that eventually, given bitcoin's active circulation, all coins once again become "pristine" since they are continuously being "laundered" by miners via transaction fees.
Which again just highlights how stupid the whole thing is. If we take tainted coins and turn them in to a fee, then all services agree those coins are now clean since they can no longer be accurately tracked due to being consolidated with other coins. But for some reason, the exact same logic does not apply to coinjoins? Because reasons?

And the others tend to already blacklist mixed funds as a whole (which is utterly stupid), or go by "shades of gray" (I don't know how to say it better) and by the rule "the stream's water can be considered clean if it went over 7 stones" (again, I don't know how to say it better and more concise).
Which is another good point as to why blacklisting is just plain wrong, in addition to the point I made above in which it is all based on guesswork. What happens if I combined a tainted input with a clean input in the same transaction? What about a tainted input with 100 clean inputs? Are all the outputs still tainted? Are they all 1% tainted? What about if a tainted input moves through 5 transactions? What about 100? What about 1,000? Is it still tainted? When does it become clean again? We've been able to trace some stolen coins to Binance. Does that mean the entirety of Binance's hot wallet is tainted? Or does the taint magically disappear once Binance have touched the coins?

Go far enough in to the future, and every bitcoin in active circulation will be tainted in some way or another.


Curiously, I used pretty similar reasoning as you when tried to explain why it is utterly stupid and absurd to deem bitcoin transactions or particular UTXOs dirty, tainted, or non-fungible.

Another shower thought about tainted bitcoins and why it is pointless to call certain bitcoins dirty, illegal and for criminals. Imagine a transaction coming from twitter hackers, for instance. All the UTXOs involved in given transaction are now considered illicit. All bitcoins are now dirty. But what about a fee hackers need to pay in order to have their transaction mined?

Basically, imaginary twitter hackers used dirty bitcoins to incentivize miners, they merely bribed them. Fees is a part of coinbase transaction  (coinbase transaction is a transaction with which miners are paying rewards to themselves, it consists of block subsidy (new bitcoins) + transactions fees (sum of all commisions from all included transactions).

What is really interesting about a coinbase transaction is the fact it does not consume any existing UTXOs. What it means is that surveillance company like Chainalysis cannot figure out what part of fees included in coinbase transaction is still dirty. Now they have to call all bitcoins from given coinbase transaction illicit. Even "virgin bitcoin" can now be called illicit because some of the transactions included in a block were involved in criminal activity.

Mining can now be considered a means to launder money, since miners take dirty bitcoins and return clean ones via coinbase transactions. Every block is now tainted, demonized and is potentially serving criminals. Bitcoin is a tool for criminals. If your transaction is in the same block as imaginary twitter hackers' one, you are in trouble, you are criminal.



But I came to a different conclusion, namely, that eventually, given bitcoin's active circulation, all coins once again become "pristine" since they are continuously being "laundered" by miners via transaction fees. I think this is part of the reason why mining in general and PoW, in particular, are being targeted by the ESG mafia - this is essentially a legal and very efficient way to get rid of "dirty" bitcoins and thus destroy completely stupid narratives of taintness and non-fungibility of money.


However, if miners stop acting, as LoyceV put it, "as if bitcoin is fungible" (e.g. reject transactions from OFAC list or refuse to build block-candidates on top of blocks containing transactions from such addresses), we are in trouble.

It might still be too early to count out any competition, but Wasabi's dwindling download numbers suggest that customers do care.

Speaking of, is it even available in e.g. Play Store? I can't find it.

I'd like to believe that users care but I don't see any discussion about it in their subreddit.

Say What?  Next your going to tell me that Fiat owns Jeep!?!?!  Roll Eyes

Thinking about it a bit more. The *only* reason I could see a "financial institution" caring about using a service like this is to hide the amount of BTC their clients have, If everything is in one big mix then when they send others can't really know what else they have. Their keys stay with the institution but when sending it's all muddled.

Other then that I go back to the individuals with a lot of BTC

Or, something happened that they don't want to or just can't talk about. So they are doing this.

But lets face it, even if we hate the outcome it is fun to speculate.

It looks like wasabists don't think users would care (and they're probably right) so it's not worth splitting scarce liquidity into multiple services. And it doesn't look like there are any competitors lining up to ridicule them for chain analysis and to take their non-caring users.

Introducing HorseRadish, the CoinJoin/JoinMarket privacy wallet that doesn't cockblock any UTXOs...

Really, what's wrong with offering two or more products that provide different services?  Lincoln, Mercury, Ford, Mazda...  They all compete against each other, but they're all owned by the same entity.  How difficult would it be to have two separate products/services that offer different types of obfuscation?

Good questions, but we got the same old expected answers from Wasabi team members, and most important things sadly remained unanswered.
I understand that Wasabi and zkSNACKs coordinator are looking on all this as a business and maybe they didn't have other choice but to operate like this with blacklisting, but they should come up and say that honestly.
They said they are not using Chainalysis but I never saw what other company they plan to use for this, I don't understand why would they hide something like this.
Oh and calling Samourai wallet Scamourai is childish and totally immature, so they can't expect us to take them seriously with anything they say.

I tested new Wasabi 2.0 wallet few days ago in THIS topic, and I have to say that my experience was not very good.
There is no coin control option in new version, my Trezor hardware wallet was not working with Wasabi or it is not supported, and I couldn't even perform coinjoin after two full days of running Wasabi wallet.
I wanted to give Wasabi a fair chance but I think this new version is step back in every way, and my hope is that some new better coordinator will show up in future.

and I don't think coordinator fees (assuming the talk about providing liquidity means they'd get a share of those fees) are sufficiently lucrative to outweigh that.
I have no idea, but Wasabi have obviously reached the conclusion that the profit they will make from any potential institutional money is enough to justify censoring the average user. One more relevant quote:

Without the zkSNACKs company, it would be more difficult, if not impossible, to continue funding the developers working on Wasabi 2.0. So after researching the options and a lot of thinking and debating, zkSNACKs Ltd, the company sponsoring the development of Wasabi Wallet, announced that the default coinjoin coordinator will start blacklisting certain unspent transaction outputs (UTXOs.)

I completely agree to this.

Blacklisting is arbitrary nonsense based on provably false assumptions, and it is an affront to bitcoin.

It's indeed arbitrary. Whether it's nonsense or how bad those assumptions can be debatable - not between you and me, but between us and them.

Maybe we, as community, should start boycotting the services who don't go by 1BTC=1BTC.
I've advocated this for a long time, and I will continue to do so. Wasabi is just the latest to be added to the list.

I guess that you have to shout louder about this. The average bitcoin user (I won't call it bitcoiner just as easy) doesn't know about this and probably doesn't care much either (you know the "I have nothing to hide" mantra) until something happens to them, obviously.

How exactly do they make money? Coordinator fees?

This answers it, I hope it's not old. (Is it only me who find it odd that they are boasting they're sponsoring, but they actually charge for their service?).

Does that mean I succeeded in trying to convince you? Cheesy

As I said, you must have been misunderstanding something. I was stating that some companies do, not what I do. (It could be seen as sort of devil's advocate to say so). For me any satoshi is identical to any other satoshi. I've never avoided mixers, I've never cared about the source of this or that UTXO and I don't see any good reason I'd change that.
So "I'm convinced" long before this talk.  Wink

The second quote is also relevant to your second point, where they say they primarily want to cater to financial institutions.

That's what I was referring to as "baseless speculation". Is there any plausible explanation why "financial institutions" would want to mix their coins at all? Even with the best chain analysis there is a massive reputational risk for them to get tangled up with some "unclean" coins or just generally getting blamed for helping launder bitcoins, and I don't think coordinator fees (assuming the talk about providing liquidity means they'd get a share of those fees) are sufficiently lucrative to outweigh that.

Answer to question 9 and 21 clearly show Wasabi 2 isn't ready for release.

Quote
--snip--

Users are able to choose which coordinator they want to communicate with but unfortunately there are not many options, as running one has its risks and not many people are willing to do it.

Most users aren't even aware they can choose different coordinator, unless they're advance user who open Wasabi wallet configuration file.

Quote
Answer: Chainalysis! = chain analysis. Let’s say we have 200 inputs wanting to register for a coinjoin. We take those and 200 other random bech32 UTXO’s that we send to their API. We get back a response where they let us know if any of these UTXOs match any of the categories and criterias zkSNACKs has set. Those addresses that we accept will proceed to the input registration, those that are blacklisted will get a notification that this UTXO is blacklisted. As a reminder, Wasabi coinjoin is built in a way that the user never loses control of their coins. The coordinator is never custodying users’ money, therefore it can not seize them etc. The querying process doesn’t affect users' privacy.

1. Adding 200 other random Bech32 UTXO is pointless when they can just see Wasabi CoinJoin transaction on blockchain later.
2. If certain UTXO doesn't meet zkSNACKs criteria, that means owner of the API know owner of that UTXO attempt to use CoinJoin at specific date/time.
3. We need to trust about how the blacklist works.

How exactly do they make money? Coordinator fees?
Yes. They have claimed in multiple interviews and blog posts, including in the answers above, that they are being pressured or harassed to stop accepting certain inputs. We don't know by whom, when, why, or in what way, because they haven't chosen to answer those questions. They made it clear that the only two possible solutions to this in their view was to either stop running their centralized coordinator and therefore lose out on their revenue stream, or start surveilling their users and censoring their inputs. They chose the latter.

How is paying for some shitty service helping them with that?
By allowing them to continue running their centralized coordinator against the unknown harassment they claim they are facing.

Having said all that, they have also said on more than one occasion that they aren't actually being forced to do this at all, and this is a proactive decision on their part, so it is impossible for us to know for sure:
In a Bitcoin Magazine article, one of the owners of zkSNACKs Ltd., Bálint Harmat said the decision to blacklist was done proactively. While it is correct that there's no legislation that specifically says coinjoin coordinators must blacklist their customers' UTXOs, the challenges encountered operating the business in even the most liberal jurisdictions are numerous and multiplying.

But one other thing is that: if you, as a CoinJoin coordinator, if you want to work with institutional clients, hedge funds, insurance funds, Michael Saylor, and all these people, well, even if ZKSnacks were not to be regulated, those customers might very well be, maybe because they’re custodians of other people’s money or whatnot. And then these regulated entities can only become users of a coordinator—arguably, I’m not sure—if such a blacklisting is involved. Again, the major feedback that I got from institutionals regarding CoinJoin adoption was, I don’t want to mix with criminals—my compliance team is gonna take me apart on that one. Now, I don’t know if there is an actual concern here or if this is just, again, some preemptive speculative compliance, but arguably there is. So we might see this world where ZKSnacks specifically has a bunch of liquidity from institutionals that are just not comfortable to CoinJoin with another coordinator which has the Anyone can join policy, including criminals. And so there’s really a lot of nuance here. So yes, this alienates a lot of users—me being one of them—but also this will encourage a lot of new users to come in. And that is why it was a preemptive step from ZKSnacks, because the question was—I mean, we’re already really big, but we want to get even bigger—how do we not just attract more liquidity, but how do we also ensure that our legal set up will survive in the long run and we’re just not completely overwhelmed with court cases and things like this.

The second quote is also relevant to your second point, where they say they primarily want to cater to financial institutions.

Not at all. As I said above, Wasabi know fine well what they are doing is shitty, and they also know fine well that continuing to try to justify their shitty actions is also shitty. But it makes them money, so (in their words) we "should be grateful" and stop "whining". Roll Eyes

How exactly do they make money? Coordinator fees? How is paying for some shitty service helping them with that?

I don't understand the whole "institutional investors" thing. The idea that Microstrategy would mix coins via Wasabi, or that Wall Street would invest into a wallet that kinda sorta helps with privacy but not really - sounds utterly absurd. It seems they're getting swindled in more than one way, or it's all just a steaming pile of baseless speculation.
