One issue I understand with grin is that it depends on nodes deleting transactions yet how can you enforce that and verify it?

What I've figured out thus far is that nodes can choose to delete transactions or not. This isn't so much a privacy factor, but instead it's meant for scalability. Dandelion is what actually makes the transaction more private if I'm not mistaken.

I hope that everybody finds a decentralized way to obfuscate their funds in the future. Wasabi has some good solutions for privacy and Samourai is working on some great stuff as well.

You have messed up your re-quoting, please fix.

I have been watching my deposit addresses in Electrum. I just witnessed all of my remaining coin withdrawn. I can only assume at this point this is an exit scam. Cry

I lost a few thousand Euro

I also have almost a bitcoin stuck there

These are the two addresses where it appears a lot of coin was moved. (Including mine)

Really? What exactly makes Monero better than GRIN? Please pinpoint that for us.

DYOR, I am not shilling. I don't care if you believe me or not. Infrastructure alone without even getting into the technicals (of which I am not an expert on the cryptography) is reason enough. The future is bright for Grin by all accounts but it is just that, the future and until that materializes (if it does) there is Monero for fungability and BTC for everything else. One issue I understand with grin is that it depends on nodes deleting transactions yet how can you enforce that and verify it?

Anyway here's a good link touching on it. If you find better info go ahead and link it for me as I am interested in both projects.

Good question. I'm curious myself. Let me have a look into it!

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.

Oh yeah. How's that working out now? Obvious scam is obvious. Sorry to hear people have lost money on this.

in the light of what's happening in the mixer scene it seems to me the time of centralized mixer services had come to an end.

In the meantime better ways exists to protect your privacy. Please learn and apply for yourself.

SHUWasabi

indeed, a very good starting point for Bitcoin privacy is:

https://wasabiwallet.io

Wasabi does not compare.

Quote

Ideal fungibility requires every Bitcoin transaction to be indistinguishable from each other, but it is an unrealistic goal. ZeroLink's objective is to break all links between separate sets of coins. ZeroLink presents a wallet privacy framework coupled with Chaumian CoinJoin, which was first introduced in 2013 by Gregory Maxwell. A mixing round runs within seconds, its anonymity set can go beyond a single CoinJoin transaction's if needed, and its DoS resilience presumes a transaction fee environment above $1 Bitcoin.

boy, it was just a link to start with something to learn and apply for yourself. Roll Eyes

if you're here to learn and not for the entertainment only you will find a lot of usefull discussions to apply better privacy in your (daily) use of Bitcoin.

https://bitcointalksearch.org/topic/coinjoin-bitcoin-privacy-for-the-real-world-279249

https://bitcointalksearch.org/topic/guide-decent-mixing-methods-5146241

Sorry, its just a fact that second layer privacy will NEVER EVER compare to first layer and there is too much mis-information about that being spread about.

People put themselves at risk trusting incorrect information, in some parts of the world these can literally be life and death. I would never use Wasabi if I had Monero as a choice the two are not comparable. Wasabi is better than nothing but it will not save you if TPTB (wherever you live) are looking at you. Actually I doubt anything is safe if TPTB are looking at you in the 5 eyes.

Those are good links you just posted BTW.

Quote from: RivAngE on June 06, 2019, 07:40:26 AM

Shouldn't people just start using GRIN instead and be done with the mixing services?
I suppose it's not as helpful as mixing services because there are cases when you just want to send BTC and nothing else, but overall GRIN has many advantages,
A) You don't need to trust a 3rd party (the mixing service) to send anonymously.
B) It's even more anonymous than mixing services since you can transact without even having a public address, but instead by exchanging a transaction file with the other party *.
C) There are no fees to be pay in a 3rd party and even the network fees are very low.

*I don't 100% understand how this works, so I might have said something wrong in point B. If anyone cares, you can try understand it more deeply by reading here: https://medium.com/@brandonarvanaghi/grin-transactions-explained-step-by-step-fdceb905a853

I guess it's still a bit too complicated to use GRIN, but hopefully this will change soon in order to provide people who want anonymity so badly with a great alternative to mixing.

That is a much better Idea but yet again Monero is a better choice than grin.

But as always...DYOR

I'll wait it out mate. Hopefully the service still has PK's for those with remaining coin or at least knows who might be owed.

Unreal mate. I can not believe Blender gave a few days notice. I understand his position though there is no reason to not move the service to another .onion and allow people much more time. Possibly give someone here a way to contact that Blender trusts? So basically, I lost a few thousand euro. This seems like an exit scam at this point. Angry

Is there any way to get a message to Blender? The notice was way too short and I still have Bitcoin with the service.

Probably not. They never disclosed any email or form of contact other than their website support and this account. The website is down, and they haven't logged in here since May 31th. Y'all are in a bad spot in here. :/

If I were operating bitblender and knew LE was coming soon, I'd wipe the servers erasing everything including the BTC private keys. Of course LE has been sending coins through bitblender so they know the addresses where all the incoming deposits were aggregated. So if they catch you with those keys, they can prove you are the operator. Or if they catch you with the secret Tor uses to identify bitblendervrfkzr. So I expect the operator no longer knows those secrets, and hence can't bring bitblendervrfkzr back up and can't send your coins anywhere. If so, the coins have been destroyed.

It makes no sense to destroy private keys at all. If the funds were kept in a LE-"unsecure environment" he could, as you suggested, move all the coins to a new adress he generated somewhere safely/offline, then destroy/remove the server in which the "unsecure" keys and adresses were stored, and still keep the funds.

Then he could either mix those funds using coinjoin, wasabi, monero, chipmixer, or simply wait until a provably-fair "privacy"-provider mixer comes into the market.

Follow your bitblender deposit addresses specified in the signed letter you saved on tails persistent storage. Or look in the wallet you sent coins from. The coins sent to my bitblender input address were moved to an address with over 100 inputs totalling almost 11 BTC, all unspent.

An earlier bitblender deposit was combined with about 100 inputs totalling around 10 BTC and sent to many addresses in a bunch of steps, with the unspent change of 2.99993936 BTC ending up in 3Qth9HPoeMjbVx3BZY1Drb8RxsbZuFj4vf at 2019-05-28 20:20. Watch that address to see if it gets spent. I'm sure LE is watching it; they know it the same way I know it. I expect it will never be spent.

admin or moderator can help somehow that we get in touch with blender ? we had there customers funds on accounts !

I'm not sure if they would put the website back again a third time. But I'll PM him again in case he still hasn't wiped everything he had on BitBlender.

i still see here a lot of discussion but not one which could help us recover our funds ! admin or moderator or old member in here maybe can help us get in touch with blender ?
