SAT (SmartX) is a public blockchain technology chain developed by the SmartX community team. It is a decentralized platform that supports Pow mining and features a "Transaction DAG" structure, known as a BlockDAG project. This allows for infinite performance scalability, essentially equivalent to a traditionally architected blockchain operating system that can scale infinitely in parallel. Applications built on the SmartX platform can seamlessly integrate blockchain technology into products such as encrypted social interactions, private communications, game payments, and loyalty programs. Through its blockchain network, SmartX connects global service providers with users, building a trusted and secure social entertainment ecosystem centered around social and entertainment activities. In the future, the SmartX platform will be a multi-layered platform encompassing financial flows, information flows, and value flows. Within the trust-based value system constructed by SmartX, individuals and entities will transmit their own values through the blockchain network, forming a rich web of interconnected value networks. This will ultimately lead to a significant enhancement in societal productivity.
