Hi Yasuko, good question. It’s important to remember that Platin has Three Pillars of Security, one of which is Sensor Fusion. Our system relies on a variety of signals including Radio waves, cell tower signals, WiFi, Bluetooth signals and more. So public wifi is only one pillar. Also, all Platin communications are done under TLS, protecting them from attacks.
PTNX is the ERC20 token that Platin generated. PTN is the native token of the Platin Plexus blockchain. Once the Plexus is live, anyone who has PTNX tokens will be given PTN tokens at an advantageous rate. We will then cease to use the PTNX tokens. You can learn more about our token starting on page 20 of our whitepaper. https://platin.io/whitepaper
Collin Cavell, you are thinking very clearly about how Platin enables geospatial services to interact with smart contracts. Yes, the Platin system enables capabilities as you describe. A smart contract would be ‘triggered’ when a user is at a particular location. The exact workings of the system will not use oracles, it will be more optimized than that. Watch our medium blog for further details.
