ADD is building a data center and application platform based on the EOS data and application ecosystem, providing a transition from "Internet +" to "Blockchain+". Data flow, data analysis and data storage will form an irresistible cross-domain trend. ADD is trying to build a data bank based on EOS's real-time data center and application platform for supercomputers and super nodes. This is a scalable, low-latency, Highly interactive and with a distributed network platform that extends the security chain fence. After synchronizing data with different chain sources, ADD will use a self-built data model, data engine and indexing mechanism to provide ecological users with visualization, convenient self-designed fine analysis, provide special dimensions and industry reports and ratings. The system also provides a whole decentralized application platform for users.
