Are you saying there is no way to verify its authenticity locally?
If so, its just a Letter without Guarantee.

About 5 hours later I got this response from Support Chat:

You can also verify it locally, you can use the public key and the signature format to generate the signature.

Here is our public key so you can double check it in the letter of guarantee

The signature was created through RSA and can be verified through the public key mentioned above and the signature format.

If you dont have a specific tool to verify the signature locally you can use for example this website.

https://8gwifi.org/rsasignverifyfunctions.jsp

Enter the Public Key from your letter of guarantee, the clear text is the signature format, enter the signature itself and select SHA256withRSA as the Signature Algorithm.

We will also add the public key into our website shortly so people can compare and proof the authenticity of the public itself.

First: the public key above is the same as I received. I'll keep this post as the first public mention of UniJoin's public key.

Using a third-party website to verify a signed message is terrible for privacy, but the site might work offline. I haven't been able to test that, because I haven't been able to verify the LoG. All I get is:

Quote

Signature Verification Failed

I'll say again that verifying a signed message would have been so much easier if it's signed from a Bitcoin address.

Any idea how to verify the LoG? Depositing without verifying is what makes many people send their funds to a phishing site, and that's all the more reason why verifying the LoG should be as easy as possible.

Sorry, nope. However, since the LoG contains the public key too (which my guess would be that it would be used to verify the signature), it probably can be spoofed fully by a phishing site.
One proper way could be to publish on the website, but also on Bitcointalk and other reputable areas (eg github) the asc file with the key to verify the signatures.

Can you try to rename it to .txt? It's basically a text file with multiple sections, public key, signature format (?), signature and an actual json only at the end.

Sometimes the solution is so easy

Thanks, I never expected those 2 programs to adjust the view based on the file extension.
This shows another inconsistency though: the PUBLIC KEY part uses normal looking line breaks, the SIGNATURE uses Windows line breaks (EOL). This is highlighted in vi by adding ^M at the end of the lines.

I addressed that already:

Quote from: LoyceV on April 03, 2022, 06:36:11 AM

I can't find your public key anywhere on the website. Without that, this public key can be specifically created for only my transaction, which would still mean I can't use it to prove anything.

I'm starting to wonder if it's really not possible to verify the LoG (which also makes me wonder why I'm the only one not completing the review without checking this!):

Quote from: LoyceV on April 03, 2022, 06:36:11 AM

After about an hour I got this response:

Hi there! You can upload it here when creating a support ticket. Or you can verify it in the restore session page. Here is the link: https://[banned mixer]/en/restore.

Me:

Quote

Are you saying there is no way to verify its authenticity locally?
If so, its just a Letter without Guarantee.

For the record: without a LoG that can be verified independently, it's impossible to provide evidence if you claim you got scammed.

The Letter of Guarantee has a weird format:

Code:

letter_of_guarantee_xxxxxxxxxx_.json: ASCII text, with very long lines, with CRLF, LF line terminators

That makes it look weird in both xed and vi:

Can you try to rename it to .txt? It's basically a text file with multiple sections, public key, signature format (?), signature and an actual json only at the end.
Maybe it helps; I've opened with notepad++ under Windows and looked pretty good/understandable (not that I've checked anything else than recovering the session, which can be done with the link too).

Quote from: the Terms

I confirm that I need to download the letter of guarantee after transferring coins to the generated address of Unijoin.

There it is again: what's the point of a letter of guarantee after depositing, if I don't get it before sending funds?

➡️ We have checked this matter again, and we will amend it. Letter of Guarantee will be made available for download before the transaction must be made.

Thanks for changing this. Note that the text at Step 2 still needs to be updated:

Quote from: LoyceV on March 30, 2022, 02:17:43 PM

I assume this should be "~~after~~" > "before".

Quote from: LoyceV on March 30, 2022, 02:17:43 PM

To be continued, but not before my main concern (in red) is clarified.

Now I can continue my review:

I'm not a native English speaker, but I'd say the word "Recurring" shouldn't be here:
Image loading...

When setting multiple output addresses, the amounts can be adjusted with a slider:
Image loading...

I understand that a slider with percentages makes it look more random and is probably best for privacy, but I can imagine users would want to receive an exact amount on some of the addresses.

The captcha works quite okay on Tor.

The Letter of Guarantee has a weird format:

Code:

letter_of_guarantee_xxxxxxxxxx_.json: ASCII text, with very long lines, with CRLF, LF line terminators

That makes it look weird in both xed and vi:

(yellow is meant to censor some data)
I've tried to verify the LoG, and I've used Kleopatra for this before, but I have no idea how to verify this one. Also: I can't find your public key anywhere on the website. Without that, this public key can be specifically created for only my transaction, which would still mean I can't use it to prove anything.

Since I couldn't verify the LoG, this was a good chance to test the /en/contact/pzRrS4OtM5gzEvi]Support Chat.

This is human readable and can easily be verified by a variety of Bitcoin wallets. All you'd have to do is publish the signing address so anyone can verify it's authenticity.

I'm posting part 2 of my (still incomplete) review so I don't lose it. I'll continue after I've been able to verify the LoG.

Premium review and suggestion spreadsheet#11

1. I’ve started with the link from this very page. First note: it’s a clear net link and when doing proper mixing one may look only for TOR address of the page. I’ve found the TOR address at the bottom of the clearnet page, but it tells "Office Tor Mirror". I think that’s a typo and some may think it’s an office/contact page, you may want to rephrase that and also put it on the ANN pages and closer to the top of the web page. Ah, and a copy button may be more appropriate than connect, since another browser would be used (at least in my case).

So the TOR page does exist, you need only small cosmetic changes imho.

2. Since I don’t want to make mistakes, I did a quick look into the FAQ. I’ve found a little funny the part about hardware wallets. Not incorrect though, since those problems are real. I find it funny because you may scare off HW users. I don't know, maybe a rephrase could be needed, or maybe it's just me, especially as it's not a problem only for HW, one can have cold storage and use Electrum with online servers.
Nothing big though.

3. The question mark near Transfer Delay has only the tooltip “transfer delay” and nothing happens when I link it (both on Firefox clear net and on TOR browser).

4. I’ve noticed noticed the different amounts and delay/receive times if more final recipients are chosen – nice touch. For my small amount I’ve used only one recipient though.

5. At actual mixing, from start, you provide OrderStatus link, UniCode (the name may be misleading when one asks for support, since Unicode usually means something else), order Id, yet I was expecting the Letter of Guarantee. At a second look into FAQ I understood that probably the Letter is generated only after the 2 confirmations (it may be good that you write about confirmations in the FAQ, for clarity) and I’ve also found that the session link is enough for getting to that page (I recommend to add explanatory [?]) to Order Link and UniCode. I find Order Id a bit redundant (as it’s in the order link).

After getting reassured I’ll recover easily the session, I’ve closed the browser completely and didn’t pay attention to the confirmations since I’ve sent with pretty low fee; I returned later to the session.

6. After 2 confirmations I was able to download the letter of guarantee. Then I’ve also seen how much I should expect to receive back. Here some cosmetic changes would be in order:
* show from start, on the main page how much one should expect the fees to be (although it’s already in FAQ, I know)
* after the 2 confirmations, after the amount to be received is shown, it won’t hurt to add info about the fee (the amount and the %) so those not reading the FAQ don’t get surprised. I’ve calculated my fee to be: 1.69%

7. I’ve set a couple of hours of delay and around the expected time I’ve got the incoming transaction, which had a quite big tx fee and got confirmed very fast. Here I’ve done the math again and that fee was subtracted from the amount "they’ve promised" when the funds I’ve sent got confirmed. Which is normal, since (for my small amount) that tx fee was even bigger than their 1.69%. Whether that bit of information needs or not to be written down, I don’t know; maybe.

8. Internals. Since it boasts CoinJoin basically even in its name, I’ve been somewhat afraid that the funds will be combined with other funds, but the link between source and destination will not be broken. But I’ve checked the deposit address and at the moment the coins were sent to me (mixing is over), those initial funds are still at the initial deposit address. Nice! (actually - even after the second mix the initial inputs were not touched!).

9. Forgetting. At the moment the (mixed) tx is sent to me, the page shows "This status page and all your personal data are now deleted and will not be available anymore." If I restart the browser and try to open by the order link it’s no longer reachable: link not valid (and a proper explanation why). Good.

10. TOR again. I’ve made a second mixing using the TOR browser. Everything went good, including recovery from the Letter of Guarantee, but I’ve also found two bugs:
* here the Order Status Link is also a clear net link
* I’ve set mixing time almost 25h and not long after confirmations, the page has shown 00h 37m 25s. It’s a display bug, since after the 37m have passed it has shown correctly 23h59m59s and at the expected time the new tx was sent to me.

Conclusions:

While I find the UI is fancier than necessary, there are still some cosmetic things that could be improved and made more informative. There are minor bugs, but the only one that actually somewhat scared me (because of my schedule/plans) was the delay time display problem.

But overall the mixing simply works as expected: the money is delivered to the expected address and at the expected time and the link with the initial input(s) is broken.

0.
Premise: I am not a user who habitually uses TOR and crypto mixer.
My review and suggestions are those of a "novice" user (more or less Grin

) who uses such kind of service.
Some observations may also be elementary, but they help to develop IMHO a service that is as inclusive as possible also for who is not a regular visitor to certain services.

1.
To access the site I used TOR and the Classic url: https://[banned mixer]/
Once inside I switched to the onion address
http://[banned mixer]/
I also did the test to log in directly from the onion link and the connection is practically immediate.

2.
I like the simplicity of the homepage which clearly highlights the "start mixing" button, the main features of the site, and information on the uniJoin site. The idea of leaving the site details - type of technology used etc etc - in the second part of the home page is excellent.

3.
This option ”Recurring Client"... Is it information that is stored on your servers? Does it provide "special advantages" such as lower payment of fees? There are not information added on the website. Since it's the first item that a user will find, it would be really helpful find more information to clarify this area and how it works.
Please note, the button (?) Nearby "transfer delay" does not work (does not allow access to any information).

4.
"Guarantee letter"

Quote

The terms specify: I confirm that I need to download the letter of guarantee after transferring coins to the generated address of Unijoin.

But it is actually generated AFTER the two confirmations!
In the past with other mixers I have noticed that it is generated / downloaded automatically once the sending and receiving addresses are confirmed. Moreover it is never explicitly mentioned in your terms and conditions ... This passage to a novice can create many problems and doubts (where is my letter?)(let's imagine making a big mixing)
Regarding this point, mine pure curiosity, but how do you really manage to guarantee "up to 250 btc mix"?
(Is there any evidence of funds? Other ploys?)

5.
Question: Hypothetically, if two payments are sent to the same address, is the second one irremediably lost? Is there no way to recover these lost bitcoins?

Why not also add “estimated time to complete mixing” along with awaiting confirmations?

edit: I have noticed a difference between amount on site and amount received (probably due tx fees).
I think this should be added specified clearly before mixing (likewise cost of service and cost (estimate) of transaction)

6.
In general the process went quite "smooth" but isn't the faster that I have used. the doubt that remains is about the "letter of guarantee" which is not generated immediately after sending coins but after two confirmations.

[banned mixer] REVIEW

Website/UI Design

Website Readability

Mixing Process & Speed

F.A.Q & Support

Website/UI Design

The site design is simple, Fonts are easy to read, Home page is a bit more detailed, Content could be understood on mobile devices (3440 x 1440 screens,) but there are a lot of animations and things that must be removed, the most important of which are:

Intro video: It doesn't talk about how to mix using [banned mixer], use the site etc, it's a general intro video.

About Us: It can be made in a separate page or in the Contact Us page.

Regain Your Privacy: I don't think anyone will read it.

Why People Choose Us: Again, too many words on the homepage without focusing on the nature of the service.

UniJoin Blog Articles: It is better to remove them.

Use UniJoin To Anonymize: It is better to remove them.

If it's a bitcoin mixer, why you have "Coins We Mix."

What I like:

Support multiple languages.

Colors are attractive.

Website/UI Design review:

Website Readability

Fonts are easy to read

Site contains a lot of unnecessary pages

it is easy to know the nature of the mixer, especially this page ---> /en/faq]https://[banned mixer]/en/faq

The site is perfect for fonts in Japanese, but the Russian language needs to be modified.

You may need to add a night mode.

Website Readability review:

Mixing Process & Speed

The mixing process is simple and clear, but there are many details that must be included:

JavaScript: I prevented giving Java permissions, but the site did not work for me. It is better to think carefully about building the site without JavaScript.

Captcha: It doesn't work well with Tor, it's best to remove it.

Letter of Guarantee: I am supposed to get it before I deposit as proof that the address shown belongs to you.

The mixing process takes a long time, at least an hour.

The positive aspects are smoothness and simplicity

Mixing Process & Speed review:

F.A.Q & Support

I like the support page, it's perfect but there are some notes:

It is good for the user to get the money back if he sends amounts less than 0.001 BTC, but it is better for the warning to be clear and to consider that money as a donation to the site with the possibility of refunding if the user contacts the support team. (Such option will add a lot of tasks to the support team.)
It is better to make the lower limits in dollars or altcoins if you want to mix altcoins.

F.A.Q & Support review:

Recommendations:

Remove Captcha and JavaScript dependency
Reduce animation.
Add night mode.
Add a Letter of Guarantee as proof because the deposit address belongs to you.

Final review:

Will add more.

Hello DroomieChikito, we appreciate your feedback! Also here, all answers are in green font under your quotes.

I start with onion link with TOR.

And good to see UniJoin also accept taproot addresses

Quote

1. I just suggest to make Onion link with .onion behind. Because when I copy-paste it to TOR, I got only this: unijoinxaogdzmk3bonngoxxoaezkmsfdyrtfyximisungh2dnc2azad, so better to create complete link to : http://[banned mixer]

And it's not needed to create connect button because when I click it, the link still directing to my clearnet (default) browser not on TOR.

➡️ We will revise the Tor link in the footer. Thank you!

Quote

2. Order status link still direct to Clearnet link: https://[banned mixer]/en/order/... so this is not even better when people use TOR, I suggest creating a .onion link like http://[banned mixer]/en/order/...

➡️ Normally, it should be an onion link of course, if the site was visited with an onion link. We will check that too and amend it.

Quote

3. I don't have a problem with captcha, but if you don't mind better to use text captcha. Because sometimes, the TOR problem is the image does not currently appear.

➡️ We know that captchas sometimes make problems when using Tor browser. But this is more with Google captcha. With hCaptcha we never experienced and issues but will observe it of course.

Quote

I have the Question, What happens if the user lost Order ID/Link and LoQ (letter of guarantee), can still restore it and how?

➡️ If the user loses his order link and his Letter of Guarantee, it will be impossible to restore a session. The user simply needs to wait until the order is completed then. That's why we display many hints on the order process to save these data.

Overall all went smoothly, I was already mixed my 0.0015 BTC without a problem. I have received a notification after sending the payment, and my coin was already mixed after getting confirmed.

I used default Transfer Delay which means I have waiting approximately 2 hours +

archived

and all was done

After that, I was confirmed, the received address was available in explorer.

I have the Question, What happens if the user lost Order ID/Link and LoQ (letter of guarantee), can still restore it and how?

Before I will dive to the Mixer feature, I just want to compliment the Aesthetics of this mixer. Typical mixer usually has a plain and simple design due to its nature of one time use only per session so aesthetics is not that important to this kind of industry but Unijoin break the norm and bring us a cool touch design that is fresh to the eyes by choosing water as theme of this casino. Watching the Bitcoins inside the bubbles with waves animation while waiting for my deposit is really calm my mind and gives more patience.

Link to the animation that I describe above:

Code:

https://[banned mixer]/main/img/mixing.mp4

➡️ Thank you very much for your compliments! We really appreciate it!

Quote

During the "Opration Detail" procedure, I'm confused how to adjust the delay and what's the purpose of the 100% note besides the delay time. Adjust slider is separated to the delay time display which is not easy to notice at first glance especially if newbie mixer user like me will first use this service. I try to click the percentage to adjust but it's not clickable, It took me more than 10s to finally notice the use of slider below. Maybe you can reposition the delay timer display below the "new address button" or make smaller the "new address button" and increase te size of slider.

➡️ We understand your points and we will take action to improve the usability and understandability of the mixing process.

Quote

On sending coins part, I think you should indicate the fees so that user will be aware on what will be the possible fees he will pay because the faqs section contains a lot of info while some user like me will go straight right away on the mixing process and will based all the info displaying on the screen. It will be good if the fee is already visible during the deposit stage to avoid any confusion or to save time browsig the faqs section for a hassle free mixing experience.

➡️ You are right, there is no indication that shows how much the fees will cost. Only in the /en/faq#what-are-the-fees]FAQs and /en/pricing]Pricing page. The fee for a mixing order is randomly generated with 4 decimals to ensure high privacy to our users. However, we can add the percentage range in the first page when creating a mixing order, to show our clients what fees they can expect.

Quote

I don't encounter any issue about the mixing process from depositing to mixing since I received immediately my mixed tokens right after the completion screen show that my mixing is finished. I just feel that something is missing on the whole process and realize that the last part don't give me a receipt on what's the expected amount that will received in my receiving address. It will took a minimum of 1hr just to know the expected result amount of your mixing since you will need to finish the mixing coutdown.

➡️ The approximate amount which will be received by the address(es) are shown when the transaction is confirmed and the mixing process has started. In the site where the mixing is currently happening, there is a list below, with the receiving addresses (censored) and the amounts that these wallets will respectively receive. However, the transaction fee is not calculated in this amount and it will be deducted from there.

Quote

Overall, I can say that Unijoin is one of the best mixer in the crypto industry right now due to its simplicity and straightforward service that most user can easily use and there's a complete warnings and signs to protect/remind user on the possible scenario for misusing the mixer in every steps until the mixing finish!

Best of luck Unijoin!

Thank you once again for your great feedback! We will do our best to become better and better and to make the world more aware of the importance of privacy and anonymity. If you have anything else you would like to share with us, we would love to hear from you!

Hello notblox1, we would also like to thank you for your detailed feedback! Every point of your feedback is considered carefully and replies are in green font under your quotes.

I need to add one suggestion here, there is question mark (?) and slider, but I think there should be some short explanation showing up with mouse hover.

➡️ Thank you! Also LoyceV made us aware of it, and we will either add an explanation & suggestion to it (tooltip) or fully remove it.

Quote

It is not clear if I have to send round numbers or not and there is no word about that on their website, correct me if I am wrong.
I just sent all my random number of coins from one of my addresses.

➡️ It is not mentioned in the process of creating a mixing order. We will add it there. But it's mentioned in the FAQs in the point "How do I achieve the maximum level of mixing". However, this FAQ will be amended, too.

Quote

One problem I noticed after I kept Tor browser window opened all time and waited for transaction confirmation, but it stills show Awaiting Payment info, and I am sure that payment was received on address:

To fix this, I did simple copy of address and opened it in new tab, only than I saw confirmation of received coins with countdown of time I selected for mixing of coins.
I think this should be done automatic without me needing to open new tab and close my old one or refresh the page.

➡️ Normally, it should take you automatically to the next page when the transaction has been detected/confirmed. We will check that again and make sure that it will be automatically redirected. May we ask what Security Level you are using on your Tor browser?

Quote

Earning 5%-10% for sharing referral links is a good idea but I am not sure it is best for privacy.

➡️ We have taken various security measures to protect the privacy of our users/affiliates:
The commission of an order that came through an affiliate is calculated directly with the receipt of the BTC. After that, a commission is randomly generated (between 5-10% with four decimals) for the affiliate and credited to the affiliate’s balance in his affiliate dashboard. After that, there is no connection between the referral and affiliate, because firstly, the commission is randomly generated, secondly, only absolute numbers is shown to the affiliate, so the affiliate cannot offset any amount. And thirdly, the affiliate is only shown the date the commissions is received, so he has no information about when the commission was credited.

Quote

Fees for this mixing are low and acceptable for me, but I think there are some things that needs to be improved on Unijoin website.

I want to see some comparison with other bitcoin mixing websites that exist, and better explanation for bold claim that Unijoin is making Chainanalysis impossible.

➡️ We will shortly publish an article in the blog section about CoinJoin technology and explain why it's in our opinion the best technology to use in Bitcoin mixing to increase privacy & anonymity with Bitcoin transactions.

We would like to thank you once again for your feedback and efforts to try out our service. We hope that on the whole you were satisfied, and we will immediately start on take your feedback and use it to improve our service.

Your Bitcoin Mixer

Quote from: LoyceV on March 30, 2022, 02:17:43 PM

Hello LoyceV! First of all, we would like to thank you for your honest and detailed feedback about your experience with UniJoin! Many of your points will help us to improve the user experience for our clients!

All responses to your feedback are in green font under a quote of you.

Quote

When possible, I choose a .onion instead of clearnet. It turns out [banned mixer] has a ]Tor mirror, but it's not mentioned in the ANN.

➡️ We will add the Tor mirror to our ANN thread.

Quote

User Interface
The first thing I noticed was excessive animations, which I strongly dislike (and UniJoin seems to love them). It reminds me of thousands of ICO websites that use heavy animations to impress users before running off with their money.
I prefer a website on which I scroll down and see the content instantly, instead of a website where everything slides into place every time I click PgDn. Waiting for the animations to finish is time lost that I can't use reading the content.

➡️ As you have already mentioned, we are really a big fan of a beautiful & modern user interface, including animations and so on. As for the page loading time, we will work on some improvements to increase the site performance.

Quote

At 1. Operating Details, after Transfer Delay, there's a "?". I expected a popup or clickable info, but there's nothing. The slider works and it's quite obvious what it does. I'd say remove the "?".

➡️ You are right, this popup is not working at the moment. We will remove it for now or add an explanation of what transfer delay means. Bitcoin newbies who don't know how Bitcoin Mixers work may not fully understand what transfer delay means, and why it is important to choose a random transfer delay, as it improves the privacy of a Bitcoin transaction.

Quote

After I clicked Continue, I got a Captcha. That was unexpected and a weird place.

➡️ We placed the Captcha at this point to prevent bots from creating thousands of orders.

Quote

Quote from: the Terms

I confirm that the address generated in the next step is valid for 24 hours only. Cryptocurrency funds sent to this address after 24 hours will not be accepted.

What happens if fees rise and the transaction takes 4 days to confirm? That's currently not very likely, but it has happened many times in the past.

➡️ This is not a problem as long as BTC is transferred within 24 hours. Even if the transaction has 0 confirmations, but a payment is detected, the address will be saved until it has two confirmations.

Quote

Quote from: the Terms

I confirm that I need to download the letter of guarantee after transferring coins to the generated address of Unijoin.

There it is again: what's the point of a letter of guarantee after depositing, if I don't get it before sending funds?

➡️ We have checked this matter again, and we will amend it. Letter of Guarantee will be made available for download before the transaction must be made.

Quote

Quote from: the Terms

I confirm that I have read and agree to the Terms and Conditions.

That's 9 pages of "legal language"! It's not very customer friendly to demand users to read 9 pages before continuing.

From /en/terms-and-conditions]Terms and Conditions:

Quote

The service is provided on a non-custodial basis.
~
trustless CoinJoin

I'll get back to this later.

I'd say 1.3 is unnecessary and a waste of time to read:

Quote

It is Your responsibility to keep your wallet backups, your wallet files, and your passwords secure.

I mean: it's obvious that's how Bitcoin works.

I strongly dislike point 5:

Quote

Any feedback (or similar content/document, feature suggestion) you submit is non-confidential and will become the sole property of the Service Provider. We will be entitled to the unrestricted use and dissemination of such feedback for any purpose, commercial or otherwise, without acknowledgment or compensation to You.

If I send a comment to any service, I don't expect nor appreciate it if they decide to use my email for advertising. This makes contacting the service a liability.

I'm no lawyer, but the way I read points 6 and 8 is that if UniJoin messes up and I lose my funds because of them, it's my risk and they're not liable. If that interpretation is correct, then obviously I don't like it.

➡️ We will completely revise the Terms & Conditions to make them more understandable for our users. In general, I can assure you that we fully value the privacy of our users and that only technically necessary information is stored until we no longer need it. So in terms of privacy, no one has to worry about their information. But we understand your point, so we will completely revise the T&C.

Quote

About the II. Privacy Policy: I didn't find the one thing I wanted to know: how long do you store information on my transactions, particularly linking my deposit and withdrawal addresses?

➡️ As mentioned one answer above, we only store information until it's no longer technically necessary.

Order Related Information - Is deleted right after a mixing order is completed. If nothing has been received, the information related to this order is deleted after the countdown of 24 hours has elapsed.
Support Tickets - Right after a ticket is closed, the whole chat will be completely deleted.
Affiliate Information - The commission of an order that came through an affiliate is calculated directly with the receipt of the BTC. After that, a commission is randomly generated for the affiliate and credited to the affiliate’s balance in his affiliate dashboard. After that, there is no connection between the referral and affiliate, because firstly, the commission is randomly generated, secondly, only absolute numbers is shown to the affiliate, so the affiliate cannot offset any amount. And thirdly, the affiliate is only shown the date the commissions is received, so he has no information about when the commission was credited.

Quote

I've reached 3. Send Coins:

Quote

Transfer between 0.001BTC and 250.000 BTC to the following address:

And this is where my main problem arises: UniJoin is asking to deposit anything between $50 and $12,000,000, but doesn't give me anything I can use to prove the deposit address even belongs to them! Earlier, in the Terms, I was promised a "non-custodial" and "trustless" transaction, but I don't even get a Letter of Guarantee. That means I have to trust UniJoin with anything from $50 to $12,000,000 and that doesn't make me feel very comfortable.

➡️ This is a very important question, so thank you for that! As mentioned earlier, we will now make the Letter of Guarantee available for download before a transaction needs to be performed. Experts can verify the validity of the Letter of Guarantee signature through RSA, with help of the Public Key and the signature format. It can be also checked automatically on the /en/restore]Restore Session page or /en/contact]Support page. The signature in the Letter of Guarantee is created by our server using a signature format & our private key. And the public key is displayed in the Letter of Guarantee. We will also add the public key in the footer of our website, so that our users can compare the public key in the Letter of Guarantee and on our website and verify that the Letter of Guarantee is authentic.

Quote

While we're on the subject of $12 million (and I'll remind you that I've never used CoinJoin before so I could be wrong): how are you going to CoinJoin such an amount, if there aren't several other users who deposit a similar amount around the same time?

➡️ We can guarantee that we have enough possibilities to mix such amounts via CoinJoin within 72 hours. We always recommend increasing the transfer delay for larger amounts. If the transfer delay is set too low, such large amounts may be mixed after the set transfer delay, but there will be an information for our users that the transaction is currently in a CoinJoin.

Quote

Tor settings used for testing
Security Level: Standard. I haven't tried Safer or Safest, which often breaks websites because it disables scripts.

➡️ You are right, setting the Security Level on Safest, will break the website and it won't be usable. Setting it on Safer will still make it usable.

We would like to thank you again for your detailed feedback! Many of your points have helped us to find improvements to our service and website. And it will also help many other users to read through this information to gain more clarity about the operations at UniJoin. If you have any other questions, or other feedback you would like to share with us, we would be glad to hear from you!

First of all I just want to let you know that I only use 2 bitcoin mixer including UniJoin Mixer. I will not name the first one but its a very good comparison to make this review.

Before I will dive to the Mixer feature, I just want to compliment the Aesthetics of this mixer. Typical mixer usually has a plain and simple design due to its nature of one time use only per session so aesthetics is not that important to this kind of industry but Unijoin break the norm and bring us a cool touch design that is fresh to the eyes by choosing water as theme of this casino. Watching the Bitcoins inside the bubbles with waves animation while waiting for my deposit is really calm my mind and gives more patience.

Link to the animation that I describe above:

Code:

https://[banned mixer]/main/img/mixing.mp4

On Mixer feature Side:

During the "Opration Detail" procedure, I'm confused how to adjust the delay and what's the purpose of the 100% note besides the delay time. Adjust slider is separated to the delay time display which is not easy to notice at first glance especially if newbie mixer user like me will first use this service. I try to click the percentage to adjust but it's not clickable, It took me more than 10s to finally notice the use of slider below. Maybe you can reposition the delay timer display below the "new address button" or make smaller the "new address button" and increase te size of slider.

On sending coins part, I think you should indicate the fees so that user will be aware on what will be the possible fees he will pay because the faqs section contains a lot of info while some user like me will go straight right away on the mixing process and will based all the info displaying on the screen. It will be good if the fee is already visible during the deposit stage to avoid any confusion or to save time browsig the faqs section for a hassle free mixing experience.

I don't encounter any issue about the mixing process from depositing to mixing since I received immediately my mixed tokens right after the completion screen show that my mixing is finished. I just feel that something is missing on the whole process and realize that the last part don't give me a receipt on what's the expected amount that will received in my receiving address. It will took a minimum of 1hr just to know the expected result amount of your mixing since you will need to finish the mixing coutdown.

Overall, I can say that Unijoin is one of the best mixer in the crypto industry right now due to its simplicity and straightforward service that most user can easily use and there's a complete warnings and signs to protect/remind user on the possible scenario for misusing the mixer in every steps until the mixing finish!

Best of luck Unijoin!

I started using UniJoin normal website but than I switched to Tor Mirror link that is posted in the bottom of the page on Unijoin website.
After quickly reading FAQ page with instructions, I clicked on Start Mixing button, than entered my Bitcoin address and selected Transfer Delay.

I need to add one suggestion here, there is question mark (?) and slider, but I think there should be some short explanation showing up with mouse hover.
Next page of terms showed up and I had to agree and check all fields and proceed to next step of sending my coins to address generated by Unijoin.
It is not clear if I have to send round numbers or not and there is no word about that on their website, correct me if I am wrong.
I just sent all my random number of coins from one of my addresses.

One problem I noticed after I kept Tor browser window opened all time and waited for transaction confirmation, but it stills show Awaiting Payment info, and I am sure that payment was received on address:

To fix this, I did simple copy of address and opened it in new tab, only than I saw confirmation of received coins with countdown of time I selected for mixing of coins.
I think this should be done automatic without me needing to open new tab and close my old one or refresh the page.
On this page I was presented with button to Download Letter of Guarantee, and I saved it as json file with Order Status Link, My UniCode and Order ID.
I am now waiting for mixing to finish so I can receive my coins back on new address I generated.

I tried switching different languages on website during waiting time for mixing and everything worked fine.
Earning 5%-10% for sharing referral links is a good idea but I am not sure it is best for privacy.

After waiting time expired I received my coins, page showed info that mixing was successful and status page will be deleted and not available anymore.
Fees for this mixing are low and acceptable for me, but I think there are some things that needs to be improved on Unijoin website.
I want to see some comparison with other bitcoin mixing websites that exist, and better explanation for bold claim that Unijoin is making Chainanalysis impossible.

Archive of update 1: https://archive.ph/U5aCK

UniJoin again carefully observed the situation after my last update and they decided to make less controversy. They really want to comply to the bitcointalk rules and they do respect them. Hence they want to show the effort.

It was not clear to me that asking review on the Ann thread would eventually consider paid bumping. Ann bumping was not the intention, the intention was to keep everything at one place. And logically an Ann should have been the place for it. But since there are still discomfort towards some of us, UniJoin team decided to keep the reviews on this thread instead of the Ann thread.

Sorry that I had to make change again but I think this shows that UniJoin has a real intention to work with the community and perform their good share for the community. The current OP reflects the change.

Royse777 I am staying in campaign but I think you only complicated everything with updated rules and you won't have much better results.

I agree.
@Royse777, I feel that you've overthought all this and may have been better without the updated rules.
With these rules you kinda ensure that ANN will be bumped for 25 days. Yes, only once/day, but still looks like a bumping service.

I thought [banned mixer] Premium Review is similar to BESTMIXER.IO review campaign ----> [CLOSED] Receive 0.0025 BTC for your review of a new bitcoin mixer BESTMIXER.IO, where we review the mixer from several aspects, and the best 5 reviews are chosen to be displayed on the site with the link to that topic and update Bitcointalk members review link on ANN page.

There is no need to update/bump ANN page + I don't think people are going to read ANN replies.
Overall this is my suggestion, if that's the case then I'm in. Cheesy
