Digital gold currency (or DGC) is a form of electronic money (or digital currency) based on mass units of gold. It is a kind of representative money, like a US paper gold certificate at the time (from 1873 to 1933) that these were exchangeable for gold on demand. The typical unit of account for such currency is linked to grams or troy ounces of gold, although other units such as the gold dinar are sometimes used. DGCs are backed by gold through unallocated or allocated gold storage.
Digital gold currencies are issued by a number of companies, each of which provides a system that enables users to pay each other in units that hold the same value as gold bullion. These competing providers issue a type of independent currency.
Proponents claim that DGC offers a truly global and borderless world currency system which is independent of exchange rate variations and political manipulation. Gold, silver, platinum and palladium each have recognized international currency codes under ISO 4217.
Unlike fractional-reserve banking, DGCs hold 100% of clients' funds in reserve as gold, silver, and/or platinum, which can be exchanged via digital certificates. Proponents of DGC systems say that deposits are protected against inflation, devaluation and other economic risks inherent in fiat currencies. These risks include the monetary policy of countries or territories, which are said by proponents to be harmful to the value of paper currency.
All of the other digital gold-backed currency systems can be used to buy, hold, and sell precious metals, but do not promote themselves as an "investment", as this implies an anticipated return.
