Based on Ethernet square chain, Raiden side chain and IPFs distributed storage technology, a precision advertising distribution system based on big data prochain (PRAJNA) is established. Advertisers set up tasks through smart contracts, and for users and media rewards that trigger ads, they settle in real time with PRA tokens. The platform's unified tokens, known as PRA,PRA, meet the etheric square ERC-20 tokens standard and can be freely traded through the Ethernet square public chain. Advertisers (advertiser) can purchase PRA through a digital currency exchange and use it to set up a delivery task, while media (Publisher) implanted with the Prochain SDK and the user who completes the task will receive the corresponding PRA tokens based on the task price.
