Towards geospatial blockchain: A review of research on blockchain technology applied to geospatial data

Abstract. In recent years, geospatial big data has been generated at a very high speed, and the volume is becoming increasingly massive. order to realize full potential of data, there strong requirement push embrace value open science. However, it still challenging preserve privacy integrity in sharing management. Blockchain as d distributed ledger technology series good characteristics, such decentralization, trust-free, transparency, tamper-free, consensus security, etc. These characteristics blockchain are beneficial for facilitating management, hence promoting development GIS. this paper, we provide comprehensive review on literature that involves how applied especially preservation. First, background knowledge introduced. Then, reviewed followed by conclusion topic. This understanding can be domain integrating technologies like GIS remote sensing.
