Prochain, Chinese name Prajna Chain, referred to as PRA, is a decentralized digital advertising data ecological platform, dedicated to changing the pain points of the current Internet advertising industry, such as low settlement efficiency, high traffic fraud, and mutual distrust in all links of the industry. With the hope of becoming a lubricant in the field of digital advertising, the friction cost in the industry will be minimized, and at the same time, the benefits of all parties involved in digital advertising will be maximized.

Based on the Ethereum public chain, Raiden side chain and IPFS distributed storage technology, PRA has established a precise advertising distribution system prochain based on big data. Advertisers establish delivery tasks through smart contracts, and the users and media rewards that trigger advertisements are settled in real time with PRA tokens.

Project Highlights

1. Anti-fraud: Build a full-chain tracking system, combine spiders and flow computing, use rule engines and machine learning modeling methods to identify user behavior, abnormal behavior, false processes, and establish device fingerprints.
2. Avoid institutions: Blockchain data is transparent and encrypted, and companies can easily judge whether the audience is their target user. Therefore, companies can skip the traditional advertising purchase process and directly provide bonuses to target users
3. Credible smart contracts: promotion tasks based on smart contracts are designed for advertisers. According to the real and credible advertising effect on the chain, the two parties settle in real time, shortening the account period of both parties. At the same time, it is easier to solve the related problems of cross-border business settlement.

The community marketing system has already landed. It once assisted PROCHAIN ​​to establish a community network of 30,000 people within 20 days, and realized full advertising airdrops through the smart contract hack parity wallet. The founding team belongs to the background of big data, all come from Tencent, and the employees are from first-line Internet companies such as Ogilvy, Xiaomi, Tencent, Baidu, and Sina. The team composition includes the Internet team, the quantification and market value management team, and the blockchain development team, with the advantages of the three to fully promote the project. The core members have business experience in big data precision advertising, and the team has billions of structured user data, which can effectively locate the target user groups of advertisers. Because the community marketing system can meet the marketing needs of a large number of new blockchain projects, dozens of project parties have requested cooperation and are in the waiting list.
