Papyrus - 分散的广告生态系统

Why Papyrus is Necessary

Digital advertising market of $229B is plagued by fraud traffic, brand safety issues, excessive middleman cuts, and absence of supply chain transparency. According to a survey of senior ad buyers worldwide, these issues are top of advertiser concerns.

On top of the blockchain platform, Papyrus provides decentralized monitoring and money flow management tools to digital advertisers and publishers, which help them to get visibility on third parties and ad agencies, fight fraud, control money streams, and optimize supply chain efficiency.

These tools cannot be manipulated, data for monitoring is stored immutably, and smart contracts automatically enforce money flow management rules.

For example, an advertiser can enforce automatic rules that say “fraudulent traffic won’t be paid for and brand safety violations will imply penalties for abusers.” Verifiers connected to the system provide data to verify these rules while blockchain guarantees their enforcement.

By providing these tools, Papyrus creates transparency, trust, and efficiency within the digital advertising supply chain. Papyrus is a neutral solution that doesn’t compete with ad platforms and service providers while brings benefits for all of them unless they are making money in the gray area.

How it Works

Papyrus is a scalable blockchain protocol and platform for execution of smart contracts against large datasets. On top of this platform, Papyrus builds a programmatic ad buying solution addressing the major problems of the digital advertising industry.

By securely and privately tracking trillions of impression-level events per day and applying smart contract-based ad verification and payment settlement logic, the solution creates transparency and trust between ad market players, provides visibility into end-to-end payment flows, reduces operational costs, eliminates fraud and increases ad quality, ultimately improving end user experience.

Due to its data scalability and privacy protection capabilities, the Papyrus blockchain architecture offers an extensive range of use cases not only within the advertising industry but for all business applications requiring the secure execution of smart contracts based on large data sets and their analysis, notably with AI models.
