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.

    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]

    Moreover the whole Bitcoin mixing business only makes sense because Bitcoin transactions are not anonymous. So they claim they didn't know the very fact that is at the base of their business?

      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.)

      “The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.” - George Bernard Shaw

      Sometimes the unreasonable people know what they're doing, and accomplish great things. Other times, the unreasonable people have no clue what they're doing, but are good at getting people to go along with their idiotic ideas; Trump is a good example of this one. 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. Ron Hubbard, Joseph Smith, Jim Jones, and David Koresh being good examples.

              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.

              The parent is right: the American PEOPLE elected Trump, and the rest of the government, and are entirely to blame for everything that's wrong.

                You seem to really have a problem with blaming the entire population bar none for things that are the fault of a subset of them.

                Maybe cut back on the absolutes a bit.

      Or rather people that researched the current model of how things are done (RTFM) and found flaws or opportunities not yet explored sufficiently. And thus knew enough what they were doing and had the insight to be unreasonable within a specific domain with those that didn't get it.

    Amazingly, no - for a period of time around 2013, I tried, really tried to convince any number of "internetz expurtz" that bitcoin was never, and will never be anonymous due to its design. Never did I hear anyone back me up, always did I hear: "nah, man, it's just too hard, the cops will never figure it out."
