Researchers at Johns Hopkins University in Baltimore are working to create a digital currency -- Zerocoin -- an untraceable currency that would compete with other virtual moneys such as Bitcoin, reports The Baltimore Sun.
If you haven’t used it, Bitcoin’s website describes it as a way to manage financial transactions with no central authority or banks.
Some critics say Bitcoin and similar digital systems enable money laundering and other criminal activity, the Sun says.
Matthew Green, the Hopkins assistant professor of computer science leading the Zerocoin project, told the Sun there is a need for anonymous financial transactions. The goal of his team’s work is to create a computer code that provides the same level of privacy that people have when exchanging traditional forms of money.
Two Bitcoin executives have been arrested in recent months as part of the fallout of Silk Road, a $1.2 billion online marketplace for illegal drugs, the newspaper says. Prosecutors in Maryland and New York charge that Bitcoin was used to make purchases on Silk Road.
Virtual currencies are "mined" when computers compete to solve complex mathematical formulas — the first to solve a formula is rewarded with 25 Bitcoins. The Sun says Bitcoin transactions are recorded in a public ledger which shows the size, time and number of Bitcoins sent to prevent duplication
The Johns Hopkins team says patterns in the ledger can be traced back to the user, so it isn’t truly anonymous.
Zerocoin was envisioned as computer code that would add anonymity to Bitcoin transactions, the newspaper says, but after resistance from some Bitcoin advocates it is being developed as a separate currency.
