Primas is a platform that utilizes the Distributed Trusted Content Protocol (DTCP) to provide premium quality content. By leveraging blockchain technology, Primas ensures the credibility of content and incentivizes the creation and circulation of high-quality content. Through social recommendations, readers can access personalized, high-quality content. Additionally, traditional Internet applications can integrate with Primas via APIs to tap into its capabilities. The solution is built on Ethereum and utilizes smart contracts for secure transactions. Core data is stored on the blockchain, while content data is stored using IPFS. Primas Nodes serve as a middle layer on the public chain, performing functions such as decentralized crawlers, DApp state cache, and external services. The Primas DApp operates on top of the Primas Node, enabling other content platforms to connect to the Primas Ecosystem through this Node.
