Abstract: The spatiotemporal data,which includes both time and space dimensions,is often used in some fields such as logistics and supply chain. Although the traditional centralized storage method has certain convenience,it cannot meet the needs of spatiotemporal data storage and query. In contrast,the blockchain technology applies decentralized distributed storage mechanism and uses consensus protocol to guarantee data security. The architectures and performance characteristics of the current blockchain 1.0,blockchain 2.0 and blockchain 3.0 represented by Block-DAG are studied,and their performance support,optimization modes and limitations for the spatiotemporal data are analyzed. Furthermore,the application prospect,existing problems and future research directions of blockchain technology in the field of spatiotemporal data are discussed.

Key words: blockchain technology, distributed storage, spatiotemporal data, architecture, Block-DAG architecture
