[ANN] Bitcoin Blender, anonymous bitcoin mixer

[Ryannnn]

Is bitblender.io official and secure to use? The SSL certificate is not valid:

Nah bro. It ain't safe. Either this dudes website can easily be exploited, it's got bugs, or the owner is a straight up thief.

I created a user on the dudes website. Added a new deposit address. And deposited to it:
31pVJBVbRmoFyeebUpi2GMdMMAq5EVKR1M
The dude is basically saying that's not a Bitblender address...

I know for a fact I created the damn address and the dude has a copy of the private key.
But the fool ain't even looking or just waiting to take the money.. Find a more reliable alternative.

Maybe it was a temporary issue with their certificate or just an issue on your side because it's fine here (secure and their SSL certificate is valid/working).

Well, you should have your PGP signed "Bitcoin Blender Guarantee" to prove you used their website, right?

Otherwise, how would anyone know (or how would you even be sure) if you really used their website and not a phishing version of it?

Yes it was an expired SSL certificate, the autorenew with Lets Encrypt did not work.

In this case, for registered accounts there is a "Proof of Ownership" on the deposit page, a PGP signed message which purpose is so users can validate it and be sure the deposit addresses in the message was generated by me and they are not on a phishing site.

The "Bitcoin Blender Guarantee" you talk about is given on the Quickmix page, it contains both deposit address and destination addresses, so it is a much better proof to have in case I don't deliver the coins to its destination.

No, it was the right website. The coins are sitting on the address... Clearly, this website can be exploited or the dudes a thief, or lazy. Probably a mix of each actually. Check the MF Logs, and the DB, you'll prob see my mf address.

I'm curious why people are still using this service when it seems pretty clear that it doesn't work. Is your mixer different than others in some way or did a university student just ruin your entire industry?

The thesis is from December 2017, I read it a long time ago and it does not mention Bitcoin Blender, they attack Coinmixer.se, not Bitcoin Blender.

The attack it describes requires that the mixer publicly publishes statistics on how many mixer transactions they have done over the last week (which I don't)
"In all mentioned attacking scenarios, we assume that the attacker is able to retrieve publicly accessible statistics which may be published through the centralized mixing service."

It then mentions some other flaws of Coinmixer.se necessary to identify their transactions, the most important was that they used a static transaction fee for all withdraws, on Bitcoin Blender each withdraw sent have a randomized transaction fee.

Coinmixer.se also always set a locktime of the current block on their transactions, on Bitcoin Blender it is randomized if locktime is set on transactions or not.
Further Bitcoin Blender also randomizes if RBF is to be set on the transactions sent.

There where some issues today but they have been solved now, apologies for the delays.

Holy...

Does this have anything to do with the recent hunt against some mixers by government agencies and the fall of BestMixer?

I guess so. Who knows what tumbler is next.

Or he is closing shop and running away with the profits that he has gained so far. That would be a smart decision if he isn't sure of his opsec.

Well, the only left seems to be ChipMixer... Now let's see...

This is not good news at all.

But i think it's very likely related to the recent Best Mixer saga one way or the other.

[malevolent]

This is pretty bad if they're shutting down after five years mere days after bestmixer's shutdown.

If I had to guess they had some loose ends as mentioned above, or their hosting service is no longer OK with being associated with them.

This is unfortunate news.  The service was great, I will miss it. 

I don't know anything about the management of BitBlender or where it they are based, but I can only imagine this has something to do with same troubles plaguing the folks at BestMixer.

My hope is that BitBlender and other mixing services can find a hospitable location to base their businesses and servers.

Now it's about when until chipmixer will next in front after this news, how unfortunate.

Now it's about when until chipmixer will next in front after this news, how unfortunate.

If you are on the internet, like the EUROPOL said;

"You are not anonymous."

I wouldn't be surprised if chipmixer suddenly leaves the business too. Come to think of, bitmixer.io used to be the biggest mixer and they left the business just like that, without a reason, at least not shared with the public.

They want to leave before they get raided by the armed mercenaries of the government.

Makes sense, life is too short to spend in a jail cell.

That's just a propaganda/scare tactic. It's not even that hard to stay reasonably anonymous today. The problem is when you get comfortable (among other things); that's when these people make mistakes and they catch them.

I wouldn't be surprised if chipmixer sudenly leaves the business too. Come to think of, bitmixer.io used to be the biggest mixer and they left the business just like that, without a reason, at least not shared with the public.

These mixers really should public their code online. That would make it relatively easy for clones to pop up and someone with better opsec might pick it up one day. In the meantime, use Wasabi.
