A unique token backed by mining and supplying of real gold. The cost is fixed in the metal weight, 1 SGT is equal to 1 gram of gold of 999,95 sample. Our project offers a simple process of involving the blockchain in the real economy. The core economic idea: traditional risks of exploration and production of gold are exchanged for risks of volatility of cryptocurrencies and tokens (insecurity with valuable liquid assets and protection from inflation). The release of tokens is secured by a contract for the supply of goods. Fixing the risks ratio occurs in the price of the purchase of goods in the form of a discount from the market price and is fixed in a unit of physical mass. The commodity of the contract is gold, which is a universal measure of value.
