PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA BACKGROUNDS Project Origin In the global trillions of Internet advertising markets, the marketing budget is largely owned by centralized media such as search engines and social media. Due to the lack of mutual trust between the various stakeholders in the industrial chain, there have been many non-value parts such as advertisement verification, data monitoring and advertisement interception, and the high trust cost has diverted the interests of all parties. According to recent data, the registered users of Mobile App have already acquired the cost as high as 10 ~ 50 RMB. However, for some specific types of users, the cost of acquiring users is as much as 1,000 RMB. So, whether there is a solution that can solve the trust between the parties, using technical means to reduce business delivery costs and enhance the media right to speak in small and medium media, while allowing users to control privacy and even gain? From an enterprise perspective, how to put marketing funds and optimize channels so that they can be accurately and quickly communicated to the target population has always been the need of enterprises. Google and Baidu have successfully verified the feasibility of the PPC business model. However, with the increasing market concentration, search engine marketing has gradually become a game for a few interest groups. In particular, it is difficult for SMEs to enter the market due to restrictions on platforms and bidding alliances. At the same time, due to the fact that the data of the flow side is not transparent, it is difficult for the enterprise to precisely measure the whereabouts of the resources and to measure the distortion of the funnel model in all aspects of the ROI. In addition, click fraud, which accounts for an astonishing 40% to 80% of ad serving, has left many businesses reluctant to use CPC or CPM pricing models. So, is there a solution that can optimize the marketing resources of an enterprise so that the delivery crowd can be pinpointed, the results trackable, quantifiable, click fraud free, and benefit regardless of the size of the organization? 页码:4/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA From a media perspective, traffic giants such as Google and Facebook have basically monopolized the traffic market, and both are receiving more than 85% of their new market share each year. For a large number of decentralized traffic master, the bargaining power is weak, have to form a network to unify the orders and is charged commission. In the strong side of the advertisers often delinquent accounts, due to dissatisfaction with the effectiveness of the contract contract disputes have occurred. So, there is a program that can trigger real-time billing of users on the traffic master platform and set up irrevocable settlement rules before launch so that the rights and interests of small and medium-sized traffic owners are protected? From an individual point of view, when using Internet services, it is often interrupted by sudden advertising. So far, user traffic did not bring any benefits to the user itself, so more and more users choose to use AdBlock to block the advertising content on the page, advertising is getting worse and worse. On the other hand, the user's behavior data has been controlled by big companies, privacy cannot control in their own hands. So, is there a scheme that lets the value of traffic return to the user itself, the user has the option to authorize the use of privacy, and receive ads that are relevant only to themselves? 页码:5/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA Marketing Situation According to Mary Meeker's 2017 Internet Trends Report, the U.S. internet advertising market reached 475 billion RMB in 2016, while the internet advertising market in China reached 290 billion RMB and the global Internet advertising market surpassed 1 trillion RMB. According to the company earnings report, Google global advertising revenue in 2016 reached 525 billion RMB, Facebook global advertising revenue of 178 billion RMB, both a total of 700 billion RMB. Google's online advertising business gross margin of not less than 25%, which means that the advertising business to pay more for the channel costs far more than 250 billion RMB. From the point of view of the demand of enterprises, the ROI of online advertising is the most concerned point of advertisers, followed by the security of budget and resources delivery, that is, anti-fraud, and finally it is time to consider the quality of the marketing program itself. 页码:6/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA On the other hand, the global trend of Internet users using AdBlock to block online advertising is rapidly growing, and traditional Internet advertising is becoming less effective. As the origin of the value of the Internet industry, users and media traffic should return this part of the value to users themselves instead of making profit as an intermediary platform. 页码:7/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA PROCHAIN Aims ProChain's goal is to build a transparent digital advertising data ecosystem: connecting advertisers, media and developers to improve the efficiency of settlement of advertising business, reduce the loss of advertising traffic fraud, to intermediaries, digital advertising to participate in Side to share the maximum benefits. Mission ProChain insists on "data truth" as its mission to promote the trust of all parties involved in digital advertising regardless of cost. Mainly includes: 1. Traffic Anti-Fraudulent: ProChain builds a full-range data tracking system using cluster analysis, GBM, device similarity recognition and other equipment fingerprint model, with unique POSt mechanism to effectively identify high-risk devices such as virtual machines and farm equipment, significant Distinguish user behavior, abnormal user behavior, false traffic, eliminate fraud accurately. 2. Farewell agent: ProChain provides innovative production relations, a substantial reduction in agency costs; the current digital advertising industry, one of the pain points is too many agencies and agents, as ProChain data is transparent and traceable, advertisers can easily determine Advertisers can skip the traditional ad buying process and pay directly to the target audience who watches the ad, regardless of who they view their ads. 3. Trusted Automated Billing: Each advertiser's serving task is a smart contract, because it clearly monitors the effect of each delivery, and the entire link data is transparent, then the smart 页码:8/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA contract can be settled in real time to both parties according to each effect, significantly Shorten the upstream and downstream accounts, to avoid contract disputes; as domestic advertisers in more and more delivery business in the form of PRO tokens to pay, easier to solve the problem of settlement of cross-border business; 4. Accurate Marketing: Get connected to all kinds of information silos, data governance and Real Time Bidding based on advertising, algorithms and models that apply a variety of machine learning and deep learning, targeting users and ads on a full data set Match, to achieve personalized high-quality recommendations, to ensure advertising effectiveness. Why to use BlockChain? The traditional Internet advertising market is a zero-sum game market. Advertiser, Publisher and User, due to their mutual distrust, introduce a number of worthless intermediate links such as advertisement verification, data monitoring and advertisement interception, etc. Reduce the benefits of all parties. Using blockchain solutions to innovate digital advertising at a production- relations level will dramatically reduce the cost of trust for all parties involved and create a market value of billions. 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. It is expected that in the next 1-2 years, commercial-grade blockchain public chains as well as the Polkadot and Raiden technologies will mature. The storage solutions based on the IPFS protocol will be decentralized Web3.0 media, Centralized applications provide content-bearing capabilities and blockchain media is entering a phase of rapid growth. Advertising as one of the oldest Internet business models, ProChain will also provide high- quality digital advertising solutions for these emerging Web3.0 distributed applications. 页码:9/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA Solutions of ProChain 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. ProADX: Digital Ad Exchange Platform, which enables a large number of dynamic and real- time Bidding transactions while interfacing with traffic resources and advertiser resources. ProSSP: Provides a blockchain-based supply-side platform for traffic owners and developers who own traffic resources to realize professional, efficient, and rewarding cash flow; ProDSP: ProDSP offers advertisers an Ethereum-based digital advertising smart contract market where advertisers choose contracts based on launch requirements, replenish PRO tokens and post them for live ad auctions; ProGateway: ProGateway is developed to interact the data between on chain and off chain , helping ProChain to refine the data mapping; ProSDK: Provides a customizable SDK for traffic owners for ad serving, billing, and user identification. ProAdWarehouse: Based on Ethereum's public chain data, it provides advertisers, traffic masters, and users with a credible data analysis platform for delivering data. It provides detailed log-level data to verify the real-click source of advertisements, measures users' click-throughs, and statistics any period of delivery effect. 页码:10/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA TECHNICAL SOLUTIONS Technology Architecture ProChain's portal is the dSDK and JS deployed by the Publisher, as well as the internal and external ADXs that interface with it, sending media ad requests to Load Balance. It includes access policies, access control, Chain Gateway and real-time DataTracking, which are forwarded to downstream routing ProRouter based on the nature of the traffic and the processing of each module. 页码:12/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA When the ProChain business end receives the ProRouter request, it hands it over to the internal Instance. Instances map external requests to labels in the system, quantitatively determine the quality of traffic data, match the optimal creatives on the advertiser's management platform according to the distribution strategy and pricing model, and return the results to the front end. In the case of RTB delivery, ProChain's business end determines the quality of the traffic data and forwards it to an external exchange, such as the traditional Internet AD Exchange. Further, traffic to Web 3.0 distributed applications can be forwarded to BlockChain AD Exchange on the pure chain. The DataTracking module collects traffic, channel, effect and settlement logs returned by the main transaction platform ADX and the advertisement demand platform DSP, and relies on the log service ETL to write Stream Computing on the blockchain. Since each delivery task is a smart contract, and the whole process of delivery is transparent and trustworthy, ProChainCore's settlement module, according to the contract address, settles the settlement to the participants in real time. ProDashBoard shows real-time reports with traffic monitoring and delivery monitoring. The total amount of data on the chain, the data collected by the log, the back-end management system data will be used as the data source for the report display. 页码:13/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA ProChain Anti-fraud POSt mechanism: POSt is a comprehensive scheme based on account POS and time t. Specifically, when an account is receiving a job, POSt weight is used as an account to acquire the threshold of the job. The specific calculation is: POSt = ∑ PRO' ×(TimeStamp3 − TimeStamp5 ) '∈) That is to say, an account that wants to receive a job needs to hold a PRO and needs to ensure that there is no PRO currency transaction for a certain period of time. POSt mechanism can effectively prevent the robot account batch brush task. When an account finishes a specific task, the POSt weight will be zeroed and recalculated under the account, while the higher value task will have a higher POSt weight requirement for the task account. 页码:14/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA Decentralized Delivery Flow The blockchain is a transparent database. Third parties must know and verify the authenticity and legitimacy of the transaction during the transaction process of all chainchain. Therefore, based on the whole chain of data, we can create a decentralized task flow engine and implement it through intelligent contracts through data mining and machine learning algorithms to calculate a personalized task flow that meets user preferences. ProChain delivery and tracking process is as follows: 页码:15/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA Task matching mechanism In order to better target audiences, ProChain will provide advertisers with precise delivery features, including but not limited to: account balance, POSt weight, whether to take orders, account ratings, tag matching and other dimensions. In addition, we will introduce a user feature recognition system and cooperate with the identification project to bind the personal metadata authorized by the user to the Ethernet address so that the advertiser can accurately reach the target user through the Đapp with ProSDK or JS embedded. According to Pearson's formula, we calculate the similarity between user u and label v: ;∈<=> ( R ?,; − R ? )(R @,; − R @ ) sim(u, v) = ∑ (R ?,; − R ? )3 ∑ (R @,; − R @ )3 ;∈<= ;∈<> The set of items that the user u and the label v match together is denoted by Puv, Ru, a, Rv, a respectively represent that the user u and label v match the score of task a, Ru and Rv represent the average score of user u and label v. 页码:16/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA The main features are as follows: 1) Account balance: account above a certain limit can claim; 2) POSt weight: account above a certain POSt weight can claim; 3) Whether or not delivered: only Publisher or user who has not claimed the same task link before can receive; 4) account rating: According to the Big Data rating system provided by ProChain for account classification, only higher than a certain rating of the account before they can receive; 5) Label Matching: Each task can set up no more than three labels. Users can get the task push priority by label matching to improve the matching efficiency. Machine Learning Model Based on Full-Chain Delivery Data 页码:17/32

PROCHAIN - PRECISION AD BLOCKCHAIN BASED ON BIG DATA According to the data of blockchain network, and advertisers 'goals, users' behavioral preferences and task completion, training and ranking model to calculate the probability of a task to be completed properly, and the completion of the amount. ProChain adopts the GBDT model and evaluates it using the AUC (Area Under Curve) indicator and supports real-time A / B test validation. 页码:18/32
