Bitcoin Forum

ㅤ

Thank you for the link - I've been seeing links to various mixer sites and have been wondering if it more smoke and mirrors than a real thing.  How did you come by this paper? Was it research, or had just just stumbled upon it?  It's interesting how many external to the forum sites are discussing bitcoin, but aren't taking the plunge to visit here.

Great post, Thank you. It's one of the most apprehensive articles about mixers.

Been reading articles of bitcoin mixer I really developed interest via mixing Bitcoin, I think these link will educate someone who wants to know rudiments of coin mixing especially Bitcoin to know it more better. I really acknowledge your research because it will trigger people to research positively. The only thing that made me to be over interested and excited concerning these text is the link.

This needs to be read in full.

The author has compared between the public mixers and the other private mixers which are well known to us like chipmixer, crypto and bitcoin mixer etc. It is astounding to see this topic has achieved the mastery level here.

I am not sure if you guys have read through the document, but author states that all the services are poor in terms of giving the controlled anonymity to the end user. It's thinkable how he did it though. Will definitely read this article for adding it to my knowledge.

I have visited Chipmixer before when I wanted to know more about what mixers are, I visited Chipmixer FAQ and it was educative, I learnt a lot from their site. Although, the way other mixers are working can be good, that is why the PDF in the OP will be very helpful, but I like the fact that some mixers helps users mixes bitcoin in a way already funded addresses with private keys are giving to the users, just like how it works on Chipmixer.

If someone want his transactions to be untraceable, using mixers are the best options, but we need to read very well about how the mixers we are using operate, as for me, if talking about bitcoin, chipmixer is the best and their FAQ is well explanatory.

I haven't read the whole PDF, but I would like to leave another interesting read about mixers here. Breaking Mixing Services (https://bitcointalk.org/index.php?topic=5117328.0). It was written more than a year ago, specially the concept of de-anonymized mixing services.

I am curious to have the participants in the chip mixer campaign give their opinion about this. They are usually the most reputable users of the forum, and I would say that chip mixer is also the most reputable mixer of the forum, but if what you say is true, the document does not leave a good impression on it. I suppose they'll have strong arguments to defend chip mixer.

I quickly checked the list of mixers reviewed. Is there any way to update the list there?

I saw Sudoku wallet which had exit scammed and even used misleading ads before as reported in these threads:
1. https://bitcointalk.org/index.php?topic=5261354.0
2. https://bitcointalk.org/index.php?topic=5263107.0

It's even under the "TRUSTED" mixers which is not the case anymore.

Ratimov, perhaps you can also add a warning or a disclaimer about the above-mentioned mixer?

Maybe post it on the list of mixer services thread on the Services Discussion section. There's no need to create another thread about which mixer exit scammed and which one is still running perfectly. Last time I remember Sudoku was listed as a scam mixer btw.

Thanks for sharing this Thesis paper this is really informative there's a complete details of what we need to know about bitcoin mixer. It's much better than the ones I'm searching on youtube.

only now that i learned sudoku wallet exit scammed or has unresolved scam accusations. i remember they ran their sig campaign here in the forum but short lived. but their site is still up. i actually was thinking to use their services before just to test how it works. but had no reason to do so. thanks for this thread though.
 really trust the reputable one in this business, else you will get rekt.

I think this list either has wrong information or the writer has made intentionally (he didn't research enough). ChipMixer has been proven here as trusted. Also, it is possible to break most of the mixers, there was an experiment.
Anyway, it will be good read. I will add it to my to do list and check out soon.

This is a timely notice. As far as I can tell, the PDF was written in April 2020. According to the mentioned thread, Sudoku Wallet had exit scammed in July 2020. Thus, Jaswant Pakki and his co-authors could not predict which of the services would stop operating properly. The OP has already placed a warning about this wallet in red.

I have download and read some parts of the published PDF. I was interested in chapter 7.1 of this document, especially in the methodology used in well-known Bitcoin tumblers such as ChipMixer, MuxTum, etc. From my understanding, the PDF authors sent bitcoins to each service and tracked all coin transfers. They concluded that ChipMixer is the only tumbler that adopts an academically proposed implementation called CoinJoin. MixTum incorporates the signed warranty.

I guess that honest Bitcoin tumblers will be always in demand because some users want to heighten their privacy.

This is basically a guide for all the people,who want to mix their bitcoins before sending them to their darkweb marketplace BTC address,so they could buy illegal stuff on a darkweb marketplace. ;D
Like I've said before,if you want to use a Bitcoin mixer,you have something to hide.If you have something to hide,then you must be doing something illegal. ;D
Anyway,I don't judge anyone.Everybody can perform legal or illegal activities at his own risk and most people,who perform illegal activities must be aware of the possible consequences.

Privacy is an important part of money even in legal avenues. Just like how people may want to keep bank balances and documents private for security reasons, the same may be true of BTC.

The Wasabi Wallet has a built-in CoinJoin feature:

Thank you for sharing this lengthy research on Bitcoin mixers. I've never used one myself because I've never felt the need for this. But it's cool that someone did an MA thesis on them! I like it that the thesis has schemes that simplify the understanding of how specific mixers work. It's also surprising to me that according to this study trusted mixers don't implement features that could make them more attractive to users, even though it's possible to implement them (p. 67 of the thesis). What is not included in the scope of the study but is of interest to me is what people actually use mixers for. If there were a way to conduct a fully anonymous and safe poll where people would say whether they're using mixers for illegal or legal stuff, it would be good to know. But it's hard to conduct such research meaningfully, ensuring that its results represent the real situation.

My opinion is that clear, privacy is a most important part of life. But l think how can we secure our money. Whenever we heared about attracers get loss us.l think btc mixers to harmful. Maybe they working hiden illegally way.l think so.

ChipMixer does not do CoinJoin.


It is not trustless. It is not a single transaction.

I have to bring this up again because Jaswant Pakki from Arizona State University just posted a video as a part of FC21 (https://fc21.ifca.ai/program.php) Financial Cryptography and Data Security 2021 virtual conference held from March 1st to March 5th.
He mentioned bitcointalk forum several times as very important for all mixers and he again wrongly claimed that Chipmixer is using Coinjoin, and if Pakki is member of Bitcointalk he should correct this and not spread more misinformation.
