Inspiration
The inspiration behind the project came from the lack of transparency in supply chains. For example, workers may be exploited in sweatshops, companies can greenwash unsustainable practices, and thieves may pass off stolen art without authentic provenances. Ledgr is a solution that brings visibility and security to every step of a product’s journey.
What it does
Ledgr is a blockchain-based supply chain tracking system. It records every key action in the product's lifecycle, ensuring that each step is securely documented and tamper-proof. The system offers complete transparency, allowing all involved parties to access a product's verifiable history, preventing fraud.
How we built it
The application was built using Python. Each block is hashed, timestamped and linked to the previous one, ensuring integrity. A role-based access control system restricts who can add or modify blocks based on their position in the supply chain.
Challenges we ran into and what we learned
One of the main challenges was ensuring that the blocks were correctly linked in a secure and tamper-proof way. I learned to design and implement the role-based access control system so that only authorized users could add or modify blocks based on their position in the supply chain.
What's next for Ledgr
Next, the goal is to continue improving the system, potentially integrating more features such as barcode scanning to improve product tracking and streamline the documentation process. The focus will be on making it adaptable to specific industries.
