ThingsOpreatingSystem is a Decentralized Layered Block Network Technology Based on SDAG. SDAG(Super directed acyclic graph) based on existing DAG technology to construct a hierarchical chain entanglement network. Each level of blockchain network stores the corresponding data, similar to the country -> Province -> City -> County -> District, each administrative center to manage the data, between provinces and between countries and countries, each other Care about each other's data. Separation of the entire network of block data, each block network only care about their own needs of the block data, you can reduce a large amount of data redundancy.
