JOOPS

Open Source Infrastructure The Joops scooter uses battery-powered embedded hardware that contains WiFi, GPS, A.I. Computer vision, a digital interface, and an electronic lock/ unlock switch. An I.o.T device is also installed so that it can enable/disable power to the scooter’s motor, It’s also responsible for generating a QR code. This QR code contains information such as geolocation, recipient wallet address, and rental rate in Joops token or the local fiat currency using debit/ credit cards. (There will be extra incentives when using the Joops token as payment i.e discounted rental rate) A rental session is initiated by scanning the QR code and sending a Rental Start transaction to the Bridgechain. Once the Rental Start transaction is received and forged by the Bridgechain, an event is emitted, triggering the scooter's IoT hardware to unlock the scooter for use. When the rental session is done the scooter will automatically lock, making it available for the next customer to rent. Mobile App The Joops App is the primary interface for users and works on both iOS and Android. This simple front-end design is how the end-user or scooter renter, will interact with the entire process. In a nutshell, it’s how a user rents a scooter and views the details of their ride from their phone app. A user initiates a rental using the mobile app to scan a QR code generated by the scooter's I.o.T device. After scanning the QR code, a user sets the duration of their ride based on a predetermined fee and signs the transaction. Once the Rental Start transaction is sent to the Bridgechain and subsequently forged/validated, an event is sent in real-time to the scooter. The I.o.T device then unlocks the scooter so the user can have some fun! The Joops Mobile App also comes with some cool features like monitoring real-time Bridgechain events, and native dark mode on iOS. Custom Bridgechain Important information about the state of the scooter is stored on a custom Bridgechain, this information includes scooter registration and rental status, as well as information pertaining to geolocation and rental duration. Other rules, such as fees and whether or not a rider can receive a refund for unused time, will also be configured. All of this is done through the use of the Generic Transaction Interface (GTI). GTI is a developer template to make custom transaction types without having to modify the Core framework. GTI inherently has a much lower level of complexity compared to Core and helps accelerate development and distribution. Joops project relies on the following 3 custom transaction types: Scooter Registration - This is where the Nft owner can register their scooter hire contract and make the hardware (electric scooter) available for rental. Rental Start Transaction - sent by the user, a Rental Start transaction is initiated by scanning the scooter QR Code via the Joops Mobile App. Rental Finish Transaction - A Rental Finish transaction is sent from the scooter I.o.T hardware once a ride is completed. Any unused fees are automatically refunded to the user's wallet address. Alongside custom transactions, Socket Event Forwarder a custom core plugin has also been developed and implemented to emit real-time events via web sockets to connected clients. This is used to send real-time updates to the Mobile App. Management Dashboard This dashboard is responsible for providing the real-time status of registered hardware on the Blockchain network and also aids in debugging and development of the embedded hardware and firmware. It is created using Thingsboard.io an open-source platform for data collection and visualization. This enables connectivity to devices through many common I.o.T protocols such as MQTT and HTTP. Node-RED is used for data processing and mapping, It is a flow-based programming tool that allows for rapid prototyping and connectivity of I.o.T devices. MQTT is the primary off-chain protocol used for communication between the blockchain, Scooter devices, and the analytics dashboard. The Core MQTT plugin sends real-time updates between the Bridgechain and the Analytics Dashboard, as well as the scooter, using the MQTT Protocol.
