Back in the days i remember download the wassabi wallet, but when i see all of this manipulation of data , chainanalysis and feaures with coinjoin not so clear i delete the wallet, also because it was very slow when it charge.
Are you saying there is no partnership, working arrangement, cooperation, bitcoin UTXO checking by blockchain analysis (describe it in any words you want) at all or that there is but it yields to no results for the blockchain analysis company? I've never thought highly of such companies, but I will certainly not consider them to be stupid not to realize you are feeding them with useless data. If that's what you are doing. Or, since you said that there is no willing cooperation, has Wasabi and/or zkSNACKs been forced into this deal with blockchain analysis?
There is no partnership, working arrangement, or cooperation. Coinjoin coordinators can't feed blockchain analysis companies any data at all because Wasabi clients do not give coinjoin coordinators any data at all. It has always been this way.
However, blockchain analysis companies can feed coinjoin coordinators data. Coordinators may purchase this data in order to exclude UTXOs from their coinjoins for ethical purposes because they want to avoid helping scammers hide the source of their funds, or they may use this for legal liability purposes because they want to avoid being punished by governments.
Finally, explain then how a person can be blocked from coinjoining based on the findings by blockchain analysis if the company doesn't receive or can find useful data on the history of the UTXOs?
If you receive coins from someone who isn't using Wasabi, then that UTXO has a history attached to it that blockchain analysis companies have tracked in the past. Once you coinjoin that UTXO with Wasabi, there is no way for anyone to trace the funds, and blockchain analysis reaches a dead end.
You make a very good answer, and thanks for clarify all this points, is good the explain and is a very good mode to work without altering so much the privacy of the people who use the wallet, but.....
We have TWO (at least) HUGE issues here, first of all, we have a philosopycal problem or ethical, WHO and WHY is coinjoin responsibile to say this UTXO is good and this is BAD?. You are in a forum where we are against censorship or atleast without a very good one explanation. And imagine if for us a explanation or a meddling for a external aprt, like the states, is bad can you imagine one made by a private company based on his subjetive analysis of UTXO?
Second one, imagine im a very common user and not a nerd one, and i have bitcoins on other wallet and i sent it to my wassabi wallet, for whatever reason Coinjoin and the analysis says, NO this comes from a blacklist bla bla, but i never know that, so i never receive the money..... Or my wassabi is gonna be out to trade with other persons who are blacklisted because one utxo with 0.0000001 btc comes from a suspected wallet?.
I know the point of being much more institutionalized and becomes a wallet for the future regulations, but it is what it is, and from this position we have to retaliate all of that in some point.
