Using blockchain technology, we have developed a decentralized, low-cost and privacy-protecting AI computing platform with a full range of related products and services.DeepBrain Chain is a decentralized neural network. Countless nodes across the world will supply computational power to AI companies and receive DBC as rewards. 70% of the DBC will be paid by the system and AI companies only need to pay 30%.Our token, DBC, is traded via smart contracts based on NEO. We use a hybrid consensus mechanism combining DPOS with POI.DeepBrain Chain is also a secure data trading platform which, by separating data ownership from data usage, maximizes the value of data while ensuring data privacy.
