One user who fully identified himself was only a teenager at the time of the transactions. And the 18 people whose Silk Road transactions were linked to Bitcoin Talk may be particularly vulnerable, since that forum has previously responded to subpoeanas demanding that it unmask a user's registration details or private messages. The researchers point out that they used only easily spotted addresses and simple matching techniques.
They didn't exploit, for instance, methods that other researchers have proposed for making less obvious connections between bitcoin addresses that identify "clusters" of addresses associated with dark web black markets. Nor could they use the means available to law enforcement to compel online services like the popular bitcoin wallet company Coinbase to cough up secret bitcoin addresses. More well-resourced and motivated hunters could potentially trace even more would-be anonymous bitcoin spenders, even years later.
Law enforcement has shown that it's willing to dig into the blockchain to assemble evidence of past criminal transactions. And even years-old dark web transactions aren't safe from prosecution. One German Silk Road customer was fined 3, euros by German authorities after they busted a marijuana dealer who'd kept records of his past sales, years after they had occurred.
Events like those have helped make cryptocurrency users increasingly wary of Bitcoin's privacy pitfalls. Earlier this month, cryptocurrency research firm Chainalysis noted that dark web transactions now account for just one percent of bitcoin transactions, down from 30 percent in Contraband sales, like other illegal applications of cryptocurrency including ransomware, have largely switched to newer digital currencies like Monero and Zcash , both of which promise far greater privacy by default.
But as the Qatari researchers' work shows, even improving your privacy practices can't always erase years-old evidence from the internet, particularly when that evidence is captured in the unalterable record of the blockchain. Even deleting profile information that includes bitcoin addresses may not be enough if a post has been cached or captured by services like the Internet Archive, they point out. Your cutting edge stealth today, in other words, might not save you from the ghosts of bitcoin opsec failures past.
The dark web drug dealer cryptocurrency of choice is Monero. Thousands of dark web users already found out the hard way last summer that law enforcement has ways of shutting them down. If you have some time, do yourself a favor and read all about the rise and fall of Silk Road.

Bitcoin played a crucial role in the recent growth of so-called ransomware attacks, in which hackers steal or encrypt computer files and refuse to give them back unless a Bitcoin payment is made. Bitcoin is still popular among currency speculators, and illicit activity accounts for only 1 percent of all Bitcoin transactions.
But that nearly doubled from the previous year. It is widely assumed that some of the people buying Bitcoin on legitimate trading exchanges are doing so to skirt national laws.
The rise in black market sales is particularly notable in because global authorities took down two of the biggest illegal online markets. New markets quickly popped up to fill the void.
In addition to the online black markets, the authorities have been aggressively targeting cryptocurrency schemes. But the amount of Bitcoin going into fraudulent activity still hit a new high. Illegal transactions have been a central part of the Bitcoin story since the first online black market, the Silk Road , helped give people a reason to begin using Bitcoin in Bitcoin was useful for the Silk Road because the structure of Bitcoin, without any central authority, makes it possible for a user to create a Bitcoin wallet and use the tokens without registering an identity with anyone.
There was hope among some in the Bitcoin community that the cryptocurrency would find a broader use as electronic cash, as the inventor of Bitcoin originally posited. As the value of Bitcoin increased, big companies like Expedia and Stripe announced that they would begin taking Bitcoin. But when users realized that Bitcoin had many drawbacks as a way of making purchases — like being slower and more expensive than traditional cash — there was little uptake.
Bitcoin aficionados now believe the cryptocurrency is more useful as a new kind of alternative asset, like gold. Many people on Wall Street have bought into that idea, and the Chicago Mercantile Exchange and the owner of the New York Stock Exchange both allow traders to buy and sell derivatives based on Bitcoin. Trading, however, has been tepid. Some believed that the digital token might prove to be popular in countries like Venezuela or Argentina, where local currencies are even less stable than Bitcoin.
But in those places, interest has recently fallen off, data gathered by the Block , a research firm, suggests.
