CyberVein's innovative big-data solution is built upon the PISR (Private, Interlink, Secure, Robust) distributed database, where database operations are stored on the CyberVein blockchain network operating on a Proof-of-Contribution (PoC) consensus mechanism. This solution is specifically tailored for enterprise-level "blockchain + big-data" customized services. The CVT token serves as the native utility token within the CyberVein ecosystem and is utilized for various purposes: Storage Payment: Data owners pay storage fees based on file size and bandwidth consumption. Computing Power Payment: Users compensate owners for usage, and software developers receive remuneration exclusively in CVT. Data Exchange: On CyberVein's federated learning platform, data acquirers trade data at a contracted price, facilitating distributed modeling applications. CROSS NFT Issuance Payment: DApp businesses utilize CVT to pay for storage and data exchange, and may adopt CyberVein tokens as a means of payment for issuing NFTs or conducting business according to their preferred model. CyberVein offers several essential tools: PISR Consortium Database: Enhances data management by aggregating user data efficiently, ensuring data reliability, traceability, and cross-level, cross-departmental data sharing, thereby unlocking the commercial value of data. DAG Storage Chain: Provides secure data storage with improved efficiency, low transaction fees, and scalability without block confirmation, miner elimination, and support for asynchronous verification and parallel processing. Cytrix: Enables GPU sharing, where nodes contribute GPU resources to the network and receive compensation through the Proof of Contribution mechanism, aiding enterprises or individuals in data modeling with federated learning. Federated Learning Platform: Facilitates data monetization through distributed machine learning workflows, ensuring data privacy and security while creating shared models from locally trained datasets, thereby realizing the value of data. The platform also offers algorithms to support data modeling operations.
