Powered by a Move-based smart contract on the Supra blockchain, Package Tracker records and tracks location changes and delivery statuses securely in the supply chain and logistics industry
The problem Package Tracker solves
Lack of Transparency: Traditional package tracking systems often lack transparency, leading to disputes. Our blockchain-based solution ensures all delivery updates are immutable and verifiable.
Trust Issues: By recording delivery statuses on the blockchain, we eliminate trust issues between senders, receivers, and delivery personnel.
Real-Time Tracking: Users can monitor the package's location in real-time, reducing anxiety and improving satisfaction.
Versatility: The smart contract can support various platforms working on similar projects, broadening its applicability and impact.
Challenges I ran into
Challenge: Lack of proper documentation for invoking smart contract functions on the backend using the Supra TypeScript SDK.
Solution: I explored the Supra blockchain community forums and experimented with the SDK to understand its functionality. By trial and error, I successfully implemented the required backend logic and documented the process for future reference.
Challenge: Integrating real-time GPS tracking with blockchain updates.
Solution: I used a lightweight GPS API and optimized the frequency of blockchain updates to balance performance and cost.
Challenge: Designing a user-friendly interface for non-technical users.
Solution: I conducted quick user testing and iterated on the UI/UX design to ensure simplicity and ease of use.
