Our stack utilizes QitaF eXchange Utility Tokens (QFX) to enable diverse transaction-based revenue sharing models within the smart city ecosystem. QFX tokens facilitate blockchain transactions, IoT smart sensor operations, and smart contract executions, allowing for precise, usage-based pricing. This system encourages active participation in city-wide digital initiatives while providing a flexible framework for various urban services. QFX tokens can be exchanged for qitaf loyalty points, bridging the digital economy with traditional reward systems. By incentivizing citizen engagement, our token-based approach fosters a more interactive and efficient smart city environment.
