BitMixer, the world's most popular Bitcoin mixing service has announced last weekend it was shutting down operations effective immediately.

Bitcoin mixing is a process of taking money from one account and breaking it into hundreds or thousands of smaller transactions to transfer it to another account.

For years, it was believed that Bitcoin mixing is a safe way to transfer funds anonymously from one account to another, mainly because there was no technology to track all the transactions and reveal the destination account.

In a statement, the BitMixer owners said they were shutting down the service after realizing that Bitcoin was a "transparent non-anonymous system by design."

[...] "Blockchain is a great open book. I believe that Bitcoin will have a great future without dark market transactions. You may use Dash or Zerocoin if you want to buy some weed. Not Bitcoin," the BitMixer team wrote.

"I hope our decision will help to make Bitcoin ecosystem more clean and transparent. I hope our competitors will hear our message and will close their services too. Very soon this kind of activity will be considered as illegal in most of countries," the team also wrote, issuing a warning for fellow Bitcoin mixers.

Why the Bitcoin Network Just Split in Half and Why It Matters 25 comments

On Tuesday, a faction of the Bitcoin community launched an audacious experiment: a new version of Bitcoin called Bitcoin Cash that's incompatible with the standard version. As a result, the Bitcoin network split into two mutually incompatible networks that will operate side-by-side.

[...] For over a year, the Bitcoin network has been bumping up against a capacity limit hard-coded into the Bitcoin software. Each block in the Bitcoin blockchain—the network's public, shared transaction ledger—is limited to 1 megabyte. That artificial limit prevents the network from processing more than about seven transactions per second.

Technically speaking, it would be trivial to change that 1 megabyte limit to a higher value. But proposals to do so have faced opposition from traditionalists who argue the limit is actually an important feature of Bitcoin's design that protects the network's democratic character. To participate in the network's peer-to-peer process for clearing transactions, a computer needs a copy of every transaction ever made on the Bitcoin network, which adds up to gigabytes of data per month.

Small-block supporters worry that raising the block limit will raise the storage and bandwidth costs of participating in the network, pricing out ordinary users. That could lead to a Bitcoin network dominated by a few big players, making the network more susceptible to government control and regulation—exactly what Bitcoin was created to avoid.

Big-block supporters say storage and bandwidth costs have fallen so quickly that this isn't a serious concern. And they say Bitcoin is going to need to process a lot more than seven transactions per second to become a mainstream technology with a real shot at changing the world.

This argument has dragged on for more than two years with no resolution. So instead of continuing to bicker, a group of big-block supporters took matters into their own hands. They forked the standard, open-source Bitcoin client to create a rival version of the software.

    Wait, I thought everyone knew the history of a bitcoin was traceable through the block-chain all the way back to inception. Did they build their entire business model on a misunderstanding or failure to RTFM.

    Or was I mistaken?

    Bitcoin's privacy properties are a kind of paradox: Every Bitcoin transaction that occurs in the entire payment network is recorded in the "blockchain," Bitcoin's decentralized mechanism for tracking who has what coins when, and preventing fraud and counterfeiting. But the transactions are recorded only as addresses, which aren't necessarily tied to anyone's identity--hence Bitcoin's use for anonymous and often illegal applications.

    But tracing those addresses is not impossible. http://cseweb.ucsd.edu/~smeiklejohn/files/imc13.pdf [ucsd.edu]

        However, doesn't mixing taint every transaction that involves portions of the payment used for an illegal (say silk road drugs) transaction. Which makes that transaction illegal. Which taints all of the bitcoins used for that transaction. And so on, until basically the whole bitcoin pool is tainted, and everything purchased with bitcoins.

        Civil forfeiture can then go wild.

        (And whilst that would be terrible, it would also be hilarious.)

Sometimes, the unreasonable people are actively malevolent and really good at lying, and also at getting people to follow them. This is generally how religions get started, with L.

                That's just BS. Trump was elected because of the way the electoral college system works, but the voters (all of them) are still at fault here, because they never demanded their elective representatives to change that horrible system. This isn't the first time this has happened, and the last time wasn't that long ago, it was in 2000 with Gore and Bush. Did the voters get outraged and demand the system finally be changed? Nope, they re-elected Bush instead.

        Obviously mixing will make transactions harder to follow but I've long suspected that it would not be sufficient to stop a 3 letter agency. Ultimately each and every transaction is recorded in the ledger. Is it difficult to unravel? Yes, at first. But one could surmise that it wouldn't take too long before tracking algos caught up with the mixers.

        ok.
        but a certain money transaction is NOT per se laundering.
        i suppose it only gets labeled as "laundering" after it has been determined that the money was in the first place
        obtained thru illegal means ... one comes before the other?
        thus, just using a "mixing service" cannot automatically be considered "laundering"; it has first to be determined(*)
        that the money was obtained illegally and the subsequent action of trying to "hide it away" gets the label "laundering"?
        furthermore, if the "mixing service" is in no way connected to the illegal operation, then they cannot be held responsible for the
        action from the other party? as a bank cannot be held responsible if a thief deposits money into one of the accounts?

    I don't follow bitcoin, but it seems the recent split was caused by the (predictable a long time ago) increasing transaction costs and delays. So bitcoin is now for large transactions, and bitcash for smaller ones. Methinks masking a large bitcoin transaction by splitting and recombining now becomes too costly.

    Even if wallets could be anonymous, the actual tokens never were and it would have been easy to block usage of stolen or laundered tokens. Apparently the ponzis don't want to do that (yet).

      Did I miss something? My understanding is that unlike some "e-money" strategies, bitcoin doesn't involve any form of tokens at all. Rather it's simply a secure and transparent method of tracking accounts and the transactions between them.

      Similarly, just because a bank account "contains" $287 doesn't mean that actual physical bills in that denomination are reserved to it (or even exist, thanks to fractional reserve banking), nor are they transferred when a check is written against it. Instead there's just a couple notations on a ledger - account A is reduced by amount X, while account B is increased by the same amount.

        As you say, transparent. My $1000 wallet receives $100 from a looted wallet - the next $100 I spend shows the world that I am a thief. No matter how finely divided into noncents.

          Why wait for you to spend it? Every transaction is public, so the world knows you're a thief (or at least received funds from a thief) the moment you get the $100
