Aims
ProChain's goal is to build a transparentdigital advertising data ecosystem: connecting advertisers, media anddevelopers to improve the efficiency of settlement of advertising business,reduce the loss of advertising traffic fraud, to intermediaries, digitaladvertising to participate in Side to share the maximum benefits.
Mission
ProChain insists on "data truth" asits mission to promote the trust of all parties involved in digital advertisingregardless of cost.
Mainly includes：
- Traffic Anti-Fraudulent: ProChainbuilds a full-range data tracking system using cluster analysis, GBM, devicesimilarity recognition and other equipment fingerprint model, with unique POStmechanism to effectively identify high-risk devices such as virtual machinesand farm equipment, significant Distinguish user behavior, abnormal userbehavior, false traffic, eliminate fraud accurately.
- Farewell AD Agency: ProChain provides innovative productionrelations, a substantial reduction in agency costs; the current digitaladvertising industry, one of the pain points is too many agencies and agents,as ProChain data is transparent and traceable, advertisers can easily determineAdvertisers can skip the traditional ad buying process and pay directly to thetarget audience who watches the ad, regardless of who they view their ads.
- Trusted Automated Billing: Eachadvertiser's serving task is a smart contract, because it clearly monitors theeffect of each delivery, and the entire link data is transparent, then thesmart contract can be settled in real time to both parties according to eacheffect, significantly Shorten the upstream and downstream accounts, to avoidcontract disputes; as domestic advertisers in more and more delivery businessin the form of PRO tokens to pay, easier to solve the problem of settlement ofcross-border business;
- Accurate Marketing: Getconnected to all kinds of information silos, data governance and Real TimeBidding based on advertising, algorithms and models that apply a variety ofmachine learning and deep learning, targeting users and ads on a full data setMatch, to achieve personalized high-quality recommendations, to ensureadvertising effectiveness.
Why to use BlockChain Technology
The traditional Internet advertising marketis a zero-sum game market. Advertiser, Publisher and User, due to their mutualdistrust, introduce a number of worthless intermediate links such asadvertisement verification, data monitoring and advertisement interception,etc. Reduce the benefits of all parties. Using blockchain solutions to innovatedigital advertising at a production-relations level will dramatically reducethe cost of trust for all parties involved and create a market value ofbillions.
Based on Ethereum's public chain, Raiden'ssidechain and IPFS distributed storage technology, ProChain will build a bigdata-based precision advertising distribution system. Advertisers createfulfillment tasks through smart contracts, which are settled in real time withPRO 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 Raidentechnologies will mature. The storage solutions based on the IPFS protocol willbe decentralized Web3.0 media, Centralized applications provide content-bearingcapabilities and blockchain media is entering a phase of rapid growth.
Advertising as one of the oldest Internetbusiness models, ProChain will also provide high-quality digital advertisingsolutions for these emerging Web3.0 distributed applications.
目标
般若ProChain的目标，是建设一个透明的数字广告数据生态平台：连接广大广告主、媒体及开发者们，提高广告投放业务的结算效率，降低广告流量欺诈损失，去中介代理，让数字广告参与各方共同分享最大化的收益。
使命
ProChain坚持“以数据真实”为使命，不计成本促进数字广告参与各方的信任建设。
主要有：
- 流量反欺诈：ProChain建设全链全量数据Tracking系统，采用聚类分析、GBM、设备相似性识别等构建设备指纹模型，配合独有的POSt机制，有效识别虚拟机和设备农场等高风险设备，显著区分用户行为、非正常用户行为、虚假流量，精确消灭欺诈；
- 告别中介代理：ProChain提供革新的生产关系，大幅削减中介成本；目前数字广告行业的痛点之一是中介和代理商太多，由于ProChain数据是透明并且可追溯的，广告主能够非常方便地判断出观看广告的人是不是他们的目标用户；因此广告主可以跳过传统的广告购买流程，直接向那些观看广告的目标群体支付费用；
- 可信自动结算：每个广告主的投放任务是一个智能合约，因为能清楚监控到每次投放效果，并且全链路数据是透明的，那么智能合约可按照每次效果实时给双方结算，显著缩短上下游帐期，避免合同纠纷；随着国内广告主在海外的投放业务越来越多，以PRO代币方式支付，比较容易解决跨国业务结算难题；
- 精准效果营销：打通各方信息孤岛，基于广告领域的数据治理和实时竞价技术（Real Time Bidding），应用多种机器学习和深度学习的算法和模型，在全链数据集上针对用户和广告进行匹配，实现个性化高质量推荐，保证广告效果。
为何使用区块链技术
传统互联网广告市场是一个零和博弈市场，广告主(Advertiser)、流量主(Publisher)、用户(User)三方由于互不信任，引入广告验证、数据监测、广告拦截等诸多无价值中间环节，显著降低了各方收益。而使用区块链解决方案，从生产关系层面上对数字广告进行革新，将大幅削减参与各方的信任成本，从而创造千亿级市场价值。
基于以太坊公链、Raiden侧链与IPFS分布式存储技术，建立一个基于大数据的精准广告分发系统ProChain（般若）。广告主通过智能合约建立投放任务，对于触发广告的用户和媒体奖励，以PRO代币实时结算。
预计在未来1-2年内，商用级区块链公链以及跨链（Polkadot）和侧链（Raiden）技术发展成熟，而基于IPFS协议的存储方案将为去中心化的Web3.0媒体以及去中心化应用提供内容承载能力，区块链媒体将进入快速发展期。
广告作为最古老的互联网商业模式之一，ProChain也将为这些新兴的Web3.0分布式应用提供高质量的数字广告解决方案。
