Smart Ledger Geostamping: Steps Towards Interoperability & Standards

Long Finance’s Distributed Futures research programme has an open source project, “GeoGnomo” to research and share methods for geostamping. Geostamping benefits from having memorable ways of recording areas that also aid efficient retrieval. GeoGnomo has built-to-share three approaches for recording areal information, a Quaternary Triangular System, a Quaternary Rectangular System, and a Variable Rectangular System for geostamping. Each can be used to record geographic areas into a blockchain.

GeoGnomo provides source code and an online translation from latitude & longitude areas to geocodes and back. Thus, blockchain applications have almost an instant ‘global post code’ or ‘global zip code’ system. By using consistent geocoding data retrieval is easier. Users can share information easily – “tell the drone to come to F49PUR9B7-20”, a resolution of 7.6 metres.
