Coin World News reports that on July 16 (UTC+8), the DePIN network is currently facing issues such as insufficient scalability, high costs, and fragmented user experience, which hinder its potential as a core technology for real-world infrastructure. Blockchain technology is expected to address these issues and build a scalable, secure, and user-friendly DePIN network for national digital systems. Vietnam is leading this field by collaborating with the U2U chain, which has developed blockchain infrastructure in partnership with SSI Digital. The U2U network currently supports a throughput of 17,000 TPS, connects to over 40 DePIN projects, and has established partnerships with major IoT and AI companies to provide scalable solutions.
