SAT (SmartX) is a blockchain technology public chain developed by the SmartX community team. It is a decentralized BlockDAG project that supports Pow mining and a "transaction based DAG" structure. It can achieve unlimited performance expansion, which is essentially equivalent to the traditional blockchain operating system of parallel expansion, and can expand in parallel indefinitely. Based on the SmartX platform, blockchain technology can be seamlessly applied to products such as encrypted social media, private communication, game payments, and red envelope points. Through the blockchain network, global service providers and users can be linked, and a trustworthy and secure social entertainment ecosystem can be built with social entertainment as the entry point.
