Building a Global Trustless Blockchain-Based Smart Financial System Promoting standardization of cross-chain protocols to reduce ecosystem access costs and ultimately form a “Data–Computing Power–Trust” trinity smart financial infrastructure. By deeply integrating blockchain’s distributed architecture with improved consensus mechanisms (such as DPoS+PBFT hybrid algorithms), we achieve efficient node collaboration and secure transactions. AI analyzes on-chain data in real time and combines IoT-captured physical-layer information to build a dynamic risk control system, enabling end-to-end transaction traceability.
