Tragick

Heat Map referencing Product Density for a chosen vendor
Product Batch Travel from Producer to Enduser
Vendor Location Map

Inspiration

Producers are unaware about the trace of their products from point of origin to the hands of end user consumers. Knowing this information helps business actors take responsible and logical decisions regarding logistics, marketing and product distribution.

What it does

Creates a supply chain network of producers and vendors where each products are represented as NFTs and the product instances minted from those NFTs as serial numbers represent the actual product instances. Using this trust-based DLT (Distributed Ledger Technology), the ownership of real world product instances are represented by the ownership of serial numbers by the vendors.

How we built it

The communication with Hedera local node was achieved using it's JavaScript SDK, which was abstracted using API endpoints built on top of Express. A REST API was implemented on djangorestframework with interacted with the Hedera local node through Express and the frontend user interface was built on React. Based on data collected from above implementations, business intelligence analytics was done in streamlit.

Challenges we ran into

Resource-heavy Postgresql queries slowed the streamlit web app and caused crashes. Hedera local node presented with a large latency while minting NFTs and conducting transactions.

Accomplishments that we're proud of

We've built a working standard that tracks supply chain procedures, all while on a limited time frame.

What we learned

We learned the techniques of collaborating as team, designing system architectures and giving fruition to these within time constraints. We learned about decentralized and distributed technologies and navigating abstract code bases aided with efficiency in incremental programming.

What's next for Tragick

Creating trust based marketplace where by producers, vendors and end users can hold and transfer ownership of assets.

I worked on data visualization using streamlit and API testing. The workflow was as follows :

1. Migrate the database from db.sqlite3 to a postgresql database and enter dummy data using python scripts. (https://github.com/trilochanb/tragick/tree/master/streamlit/database)

2. Implement product vendor and product analysis and display the interactive maps/data using streamlit.(https://github.com/trilochanb/tragick/tree/master/streamlit)

3. Collaborate with team members to add new features/fix minor bugs.

4. Test the API calls using Postman.

I worked on interacting with Hedera's local node using Hedera's Javascript SDK, abstracting with express.js
and creating RESTful APIs along with testing API endpoints in Postman.

"In the hackathon, I took charge of the frontend development, crafting engaging and intuitive user interfaces. Leveraging my skills in React . I ensured our project not only looked great but also delivered a seamless user experience. My contribution might not be to great but I learned more in this project.
