In essence, cryptocurrencies are currencies existing completely online and whose values exist based on speculation and, like fiat currency, existing demand.
They are decentralized, meaning no country or central bank controls their supply or price, and transactions are peer to peer with no bank or service as an intermediary. Even businesses are getting in on the action, with Facebook announcing its new cryptocurrency this week.
The increasing marketability and reach of crypto, however, raises new questions for its regulation and uses. Like traditional fiat currencies, crypto can be used both for speculation as well as for a method of payment. The other primary use of cryptocurrency is as a relatively anonymous form of payment for transactions both on the surface web and the dark web. This includes licit transactions as well as illicit transactions, such as the purchase of drugs, money laundering, and sanctions evasion.
Recent stories out of New York , Spain , and Norway illustrate cases of individuals using cryptocurrency for illicit transactions or illegal activity. Studies regarding how many illicit transactions occur with Bitcoin, the most used cryptocurrency both in general and for illicit transactions, vary from anywhere between one to 25 percent.
Regardless of these varying reports, dark web websites accepting crypto do exist. The dark web is not a wholly illicit area of the internet, rather it is only accessible using specific networks such as The Onion Router Tor instead of traditional internet browsers and search engines.
This public ledger is shared across all the computers in the network. See here for a more in depth explanation of blockchain technology and its applications. Whenever a transaction is made using Bitcoin, thousands of powerful computers around the globe work to verify that transaction. For an example on how blockchain works, imagine multiple people playing a game of poker. Instead of using chips, each individual tracks the money won or lost each hand for every player on paper.
Blockchain functions in the same way; all computers in the network track the verified transactions so that if an attempt is made to falsify a transaction, it can be caught. The public nature of the ledger makes tracking most cryptocurrency transactions fairly straightforward, even more so for cryptocurrencies like Bitcoin, which publishes the location and the actors i.
These include the use of multiple online wallets or addresses with which to hold and transact your cryptocurrencies, virtual private networks VPNs to hide your IP address, the sending of cash through an intermediary, and the use of cryptocurrency mixing services.
Mixing, also known as tumbling, blends currencies in recent transactions so as to break up traceability. While Bitcoin is the most used currency for purchases on the dark web, other currencies like Monero or Dash provide more anonymity through changing addresses or automatic mixing.
Neither of these, however, are completely anonymous, but they do aid in making illicit online transactions harder to follow, especially when used in tandem with some of the other strategies listed above.

Abstract Purpose The purpose of this paper is to highlight the intelligence and investigatory challenges experienced by law enforcement agencies in discovering the identity of illicit Bitcoin users and the transactions that they perform.
Findings An optimal solution would be one which has a predictive capability and a machine learning architecture which automatically collects and analyses data from the Bitcoin blockchain and other external data sources and applies search criteria matching, indexing and clustering to identify suspicious behaviours.
