It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency.

digital gold currency is a kind of physical currency, and its deposit is measured in gold rather than legal currency. Therefore, the purchasing power fluctuation of digital gold currency is related to the gold price. If the price of gold goes up, it becomes more valuable. If the price of gold goes down, it loses value. Since there is no specific financial regulation to regulate digital gold money suppliers, they operate in a self regulatory manner. Digital gold money suppliers are not banks, so banking regulations are not applicable. However, the global digital currency Association, founded in 2002, is a non-profit association of online currency operators, convertors, merchants and users. This association supervises the users' reports and ratings the reputation of the convertor. The rating operation is confirmed by the users' reports
