In 2013, Jean-Loup Richet, a research fellow at ESSEC ISIS, surveyed new money laundering techniques that cybercriminals were using in a report written for the United Nations Office on Drugs and Crime. A common approach to cyber money laundering was to use a digital currency exchanger service which converted dollars into Liberty Reserve and could be sent and received anonymously. The receiver could convert the Liberty Reserve currency back into cash for a small fee. In May 2013, digital currency exchanger Liberty Reserve was shut down after the alleged founder, Arthur Budovsky Belanchuk, and four others were arrested in Costa Rica, Spain, and New York "under charges for conspiracy to commit money laundering and conspiracy and operation of an unlicensed money transmitting business." Budovsky, a former U.S. citizen and naturalized Costa Rican, was convicted in connection with the 2006 Gold Age raid. A U.S. indictment said the case "is believed to be the largest international money laundering prosecution in history." More than $40 million in assets were placed under restraint pending forfeiture, and more than 30 Liberty Reserve exchanger domain names were seized. The company was estimated to have laundered $6 billion in criminal proceeds.

The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.
