The problem PharmaShield solves

Our project aims to utilize immutability and the ability to mint tokens offered by a blockchain to enforce accountability and mitigate drug flow into illegitimate channels.
This project is the broad-scope solution to the leak of drugs into illegal media due to flaws and under-the-table deals between players.

The scope of our project is broad, encompassing all aspects of the drug supply chain from manufacturing and distribution to dispensing and patient use. By utilizing a blockchain-based system, we can track the movement of drugs from the manufacturer all the way to the end user, ensuring that each step of the process is transparent and accountable.

One of the key benefits of our system is that it allows for the creation of tokens that are linked to specific batches of drugs. These tokens can be used to track the movement of drugs through the supply chain and ensure that they are only sold through legitimate channels. Additionally, the immutability of the blockchain ensures that once a transaction has been recorded, it cannot be altered or deleted, providing an unchangeable record of all drug movements.

Ultimately, our project represents a significant step forward in the fight against the illegal drug trade. By utilizing the power of blockchain technology, we can create a more transparent, accountable, and secure drug supply chain that benefits all stakeholders, from manufacturers to patients.

Challenges we ran into

Complexity of Supply Chain Processes: Supply chain processes can be complex, involving multiple stakeholders, suppliers, and distributors. Developing a dApp that can handle all of these complexities was a challenge.
We overcame this by creating a mathematical solution to keep the drug supply and token count equivalent to each other.
Solidity code: Developing the functionalities and interlinking the multiple agent functions with each other. We also had to develop a variant of the burn function.
Integration of the frontend with the backend Solidity was not completely seamless.
