Based on Ethereum's public chain, Raiden's sidechain and IPFS distributed storage technology,
ProChain will build a big data-based precision advertising distribution system. Advertisers create
fulfillment tasks through smart contracts, which are settled in real time with PRO tokens for users
and media rewards that triggered the ad.
PRO, which is the token of ProChain System, conforms to the Ethereum ERC-20 token
standard and is freely traded via the Ethereum public chain. Advertiser purchases PROs from
Digital Currency Exchange and is used to build delivery tasks. The ProChain SDK's Publisher and
users who complete the task and those who will receive the corresponding PRO tokens based on
the task price.
