Gravel Coin (GRV) is our global mining project for gravel production (stone extraction and stone crushing). We bring together the mining sector and the blockchain technology in order to improve efficiency, supply chain and operations. The token is a standard ERC-20 on the Ethereum platform pegged to 10 kgs of gravel, and the blockchain will be used to set up the Supply Chain Management (SCM) platform. This will be built on Oracle's infrastructure as Gravel Coin since 27 Feb 2019 became a participant in Oracle Global Startup Ecosystem - Oracle startup accelerator.
