OpenStreetMap Blockchain Protocol
OpenStreetMap.org (OSM) is a community driven mapping platform that offers completely free & open source mapping data, some would call it the WikiPedia for maps. Anyone is allowed to edit, download & use OpenStreetMap completely for free. Unfortunately, to build DApps using such public mapping database would require an immense amount of work to simply load the data and to keep it updated.
EOS Nation is proposing to develope a protocol which would allow DApps developpers to interact with the OpenStreetMap database directly on the EOS blockchain. In addition an OpenStreetMap monitoring system would be deployed on the EOS blockchain which would continously sync the live OpenStreetMap data to the blockchain.
