But what about tracing coins sent to multiple addresses with different delays?

In the case of using multiple addresses just [banned mixer] and bitmixer.io were vulnerable since they used the same miners fee for transfers. Altogether, it is a strange coincidence that these two systems had even the same api calls, but it's not our business...

The search algorithm is the following: find all transactions in the desired time range and not exceeding the maximum amount of payment (ie, do not take into account the minimum values), then group all transactions that have the same miner fee, and their amount is in the right range, keep the groups with 2-10 addresses (the maximum number of addresses can be less than 10; the exact number of addresses is easy to figure out) and get the correct result in almost 99% of cases.

Basing on the estimates you gave, inside of 48 hours period there are approximately 1500*6*48=432000 transactions. How come that you can analyze blockchain with 99% probability of finding outputs? It sounds like a nonsense. Obviously there are too many transaction following the pattern you described and the result of your CAE check confirms my words. I tried to put the address generated by cryptomixer, the coins were sent to 3 outputs and the output of your system was dozens of suspicious addresses. After that does it make any sense to stress this

None of them thought about the words of Bitmixer.io: '...now I grasped the Bitcoin is transparent non-anonymous system by design. Blockchain is a great open book.’

We investigated, analysed, found vulnerabilities, fixed them and made a really good product finally.
The product that protects your anonymity.

I do not say that your system is complete bullshit. You have made a lot of work and it is great. To some extent you can trace other mixers transactions. But the point is that you put too much stress in your proposals about other services work. Nothing is cracked, everything works and your service is not SO MUCH better than others. Thats the mes I want to deliver.

Dear Friends,

all tasks are carried out according to the planned schedule.
We are ready for new mixings for you 24/7.

Best regards,
BestMixer Team


Dear bestmixer, you use very aggressive marketing strategy, bumping your own threads is no good.

I am interested in your CAE check. Could you provide the details on how it works? I used couple of mixers and tried to trace my funds using your service. Well, it didn't give me any sensible information, outputs contain hundreds of bitcoin addresses and my target addresses are not listed.

The question: why do you so categorically blame other mixers? I didn't see how you crack other services with your wonderful CAE check.

Good job, motherhacker! No, we are not intend to delete the code) Everybody can use it to get a discount. To make it clear, we are giving discounts to stimulate the usage of cryptomixer codes. The first time customer interacts with our system, it is given a code. This code is then used to ensure that this customer's coins are not mixed with any of the previous coins sent by him to our reserves during future transactions. In a simple words, to prevent the scripts to give you, your coins back.

Yes, of course I understand the concept behind this code. Why dont you just lower your minimum service commission then? Now anybody can read the thread and get a discount.

Though it is not a security breach, because it doesn't compromise any sensitive data - it only let somebody get a discount, you made a great research and I would like to thank you! Your proposal sounds reasonable and we will include it in one of upcoming updates.

Glad to help your service.

I registered this account to share my findings.

Once a lot people mention some weak points of your service I tried to code a little.

I wrote a simple js script sending random cryptomixer codes to server. The server responds with a discount for each code. Running script for about two hours I succeeded to found the code with 0.1% discount: 34ntw. Anyone can check it, though they likely delete the code soon after posting.

My message to cryptomixer: please guys, improve your server responses. You can restrict the rate per IP, for example. Turns out that 5 letters code does not give you good level of security.
