Observer (OBSR) is a cryptocurrency project that addresses the challenges associated with collecting climate information at the retail level. Launched in 2018 by a team based in Korea, OBSR provides hyperlocal weather information, particularly in South East Asia. The platform encourages individuals and businesses to share real-time weather data collected through various means such as smartphones, automobiles, mini weather stations, vessels, or aircraft. The data collected is managed using big data technology and the observation history is recorded on a blockchain for legitimate compensation. This approach provides an alternative to the limitations of public observation networks and inefficient data exchanges between countries.

Observer operates on a model where anyone can share real-time weather data that they collect using various devices. The collected data is managed through big data technology and the observation history is recorded on a blockchain for legitimate compensation. The platform encourages observations by individuals and businesses, verifies the quality of the data, and facilitates transparent data transactions. The Observer foundation performs multiple roles including quality control of real-time weather observations, archiving them into the database, and providing routine compensation (OBSR coin) for successful observations. All transactions within the Observer platform are made using OBSR, a transaction coin.

The potential use cases for Observer are vast and varied. Weather information plays a role in various industries such as logistics, leisure, energy, agriculture, and fisheries. Observer's data may be used by weather service providers to offer real-time information on urban weather or to make hyper-local short-range weather forecasts. Airlines and ship routing companies may use Observer’s real-time weather data to check airport weather and monitor clear air turbulence. Local governments looking to develop smart cities may also benefit from the data archived in the Observer. Furthermore, the data may be used in sectors like agriculture, food, medicine, travel, leisure, health, beauty, insurance, retail, automobile, energy, military, science, disaster prevention, and public services.

Observer was launched on 10th August 2018 by a team based in Korea with the intention of addressing problems with climate information collection at the retail level. The project was designed to provide hyperlocal weather information, particularly in South East Asia. The platform was built to encourage individuals and businesses to share real-time weather data collected through various means. Over time, Observer has become a platform that not only collects and distributes real-time weather data for regions where public observation networks are not well established, but also provides a platform for transparent data transactions. The Observer foundation plays a role in controlling the quality of real-time weather observations, archiving them into the database, and providing routine compensation for successful observations.
