BHT is dedicated to building an ETH-based Internet 3.0 data and application ecosystem. Relying on ETH, we construct a data sidechain, providing the internet and big data industries with a transition from "Internet +" to a more advanced "Internet +" through a data hub and data application platform. This will be an expandable, low-latency, high-interaction, distributed network platform equipped with scalable security chain domain safeguards. BHT develops its own data models, data engines, and indexing mechanisms to offer eco-users visual, convenient customization for finer-grained analysis, specialized data flow services, and a data analysis application system. Additionally, it provides users with a one-stop decentralized data application and internet service platform solution.
