For a large part of its existence, the Bitcoin BTC community placed a lot of faith in the cryptocurrency becoming a viable alternative to many centralized payment systems existing in the market. However, BTC currently is mostly used as a long-term investment — an asset much like gold or stocks. How and why did this happen? The main problem is the amount of transactions that the network is able to process. As more and more people started using Bitcoin and sending transactions, the network became bloated. Along with the amount of transactions, the waiting times and, most importantly, transaction fees have skyrocketed. According to blockchain.

Researchers at Qatar University and the country’s Hamad Bin Khalifa University earlier this week published findings that show just how easy it may be to dredge up evidence of dan bitcoin transactions when spenders didn’t carefully launder drigs payments. In well over cases, they could connect someone’s gitcoin payment on a dark web site to that person’s public account.

In more than 20 instances, they say, they could easily link those public accounts to transactions specifically on the Silk Road, finding even some purchasers’ specific names and locations. Bitcoin’s privacy paradox has long been understood by its savvier users: Because the cryptocurrency isn’t controlled by any bank or government, it can be very difficult to link anyone’s real-world identity with their bitcoin stash.

But the public ledger of bitcoin transactions known as the blockchain also serves as a record of every bitcoin transaction from one address to. Find out someone’s address, and discovering who they’re sending money to or receiving it from becomes trivial, unless the spender takes pains to route those transactions through intermediary addresses, or laundering services that obscure the payment’s origin and destination.

But few if any researchers have actually documented their work to exploit those properties of bitcoin and count identifiable dark web transactions. To do so, the Qatari researchers first collected dozens of bitcoin vrugs used for donations and dealmaking by websites protected by the anonymity software Tor, run by everyone from WikiLeaks to the now-defunct Silk Road.

Then they scraped thousands of more widely visible bitcoin addresses from the public accounts of users on Twitter and the popular bitcoin forum Bitcoin Talk. By merely searching for direct links between those two sets of addresses in the blockchain, they found more than transactions made to those dark web sites’ accounts—very likely with the intention of preserving the senders’ anonymity—that they could easily link wiith public bticoin. Among those, 46 were donations to WikiLeaks.

More disturbingly, 22 were bktcoin to the Silk Road. Though they don’t reveal many personal details of those 22 individuals, the researchers say that some had publicly revealed their locations, ages, genders, email addresses, nitcoin even full names.

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 wigh 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 yoi shown that it’s willing to dig into the blockchain to assemble bbitcoin 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 eith marijuana dealer who’d kept records of his past sales, years buh they had occurred. Events like those have helped make cryptocurrency youu 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 Zcashboth 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.

Your cutting edge stealth today, in other words, might not buyy you from the ghosts of bitcoin opsec failures past. The dark web drug dealer cryptocurrency of choice is Monero.
