Platin is a lightweight, secure and verifiable Proof of Location (PoL) protocol on the blockchain. Platin (Platin.io) combines location data with a lightweight and secure Proof of Location (PoL) protocol to enable geospatial capabilities in the decentralized world. With Platin anyone can geo-locate a digital asset (cryptocurrencies, documents, images, etc.), anywhere on the map, anywhere in the world, in real time. This is made possible through open, privacy preserving zero knowledge proofs developed as part of the Platin protocol. With Platin, any digital asset can now have a fixed location in physical space. This incentivizes individuals, organizations and large groups of people to move and interact with digital assets - and each other - in brand new ways. Developed by a world-class team of professionals and academics experienced in blockchain, security, mobile and AR, Platin enables unique use cases not possible until today through its decentralized protocol based on incentivized location witnessing. Platin's protocol is interoperable and extensible, with the potential to transform every industry, from retail to humanitarian aid, from automotive to supply chain, security, finance and more.
