The project is really interesting and if understand correctly it's a safe p2p decentralized marketplace where people can sell and buy anything, it's really similar to safeexchange but with the possibility to create smart contracts. The only thing I don't really like it's there is no mining, staking involved or any other compensation involved.
There is no mining,etc. because this is a token launched on Ethereum platform
