## 3 Use-Case Definition
### Virtuous Cycle of Road RADAR Signature Data  
As represented in Figure 6, the road RADAR signature workflow is facilitated and augmented with acknowledgment, data certification, transparency, privacy, dynamic pricing mechanism accompanied by fidelity and incentivization mechanism. Our data monetization use case involves the following components realized through the development of pallet smart contracts on the Substrate blockchain framework:  
* Asset Component: This component creates an asset for vehicle OEM as a non-fungible ERC 721 token in the network. RADAR data of the vehicles for a defined condition of localization, time period, error tolerance and other miscellaneous metadata are represented as an asset along with its floor and ceiling price.
* Asset Service Component: The component is similar to the asset component but consecerated towards the road RADAR signature map, which is offered by the RADAR OEM to the vehicle users for enhanced safety, autonomicity, and optimized localization information which is accompanied by a ceiling and floor price.
* Bidding Component: Each asset or asset service created as an ERC 721 token has its price determined based on a transparent bidding process between RADAR OEM, Vehicle OEM and Vehicle Users consenting to the transaction.
* OffChain Component: As soon as the asset or the asset service is sold, data must be offloaded from each vehicle to RADAR OEM via Vehicle OEM. Vehicle OEM acts

as a guarantor or mediator in the blockchain for initial data collation, data cleaning and obfuscating of any sensitive or private data. These data processing steps are performed offchain in a cloud middleware but closely looped with the blockchain to certify the process and the data.
* Asset Data Collation and Certification: The data offloaded to the RADAR OEM are then processed, analyzed and interpolated with map data to be offered as a service later completing the asset finalization along with certification along its entire process.
* Asset Service Offering: Road RADAR map signature is offered to the consenting vehicle back in the blockchain ecosystem with an interest of subscriptions collated in the ledger by Vehicle OEM and transaction completion post the fund transfer.
* Incentivization for Everyone: For each transaction of asset or asset service involving RADAR data monetization and Road RADAR Signature Service, each actor in the ecosystem is attributed an incentivization. The asset monetary transaction distributes the commission to Vehicle OEM, Vehicle Users, and RADAR OEM. The necessary monetary benefit along with data certification, anonymity and quality are maintained. Moreover, the RADAR data or RADAR signature service represented as tokens ascend in price appreciation based on usage review submitted to the smart contract.
* Cyclical Economy Monetization: In the proposed architecture, the vehicle owners can monetize their data generated in the form of credits which can be later reclaimed or used in subscribing to any services like insurance and maintenance offered by Vehicle OEM. Also, the advantage for Vehicle OEMs is creation of repeated sales of products and services benefitting the customer as well as the organization subsidizing the cost of building a vehicle connectivity infrastructure. RADAR OEM can improvise their services and products leveraging from the vehicle owners data. The data can be used to train and optimize the services offering an intelligent and custom-tailored solution to each vehicle in the form of traffic advice, road conditions, driving behavior, etc.  
This completes the explanation of the virtuous data cycle since its inception as an asset from the vehicle to its collation in the RADAR cloud. Then this asset is utilised to create an asset service for the vehicle users based on the shared data imbibing fidelity and sustained benefit for everyone in the monetization ecosystem.
