Inspiration

As consumers in this hyper-capitalistic, we believe that we have the right to know when, where and how our products comes from. Its sources, stories and impacts. That's why we built WHAT AM I, is a block chain of production that renders every step of the process.

What it does

WHAT AM I records the start to end process of products at the component level. Each component is traceable from its origins from material sourcing, assembly, work conditions, and logistics. This enables consumers to make quick and reliable decisions that align with their values.

How we built it

We built the backend with FastAPI, using self-written centralised blockchain algorithm. Users can partially or fully download it to verify the integrity of the data, ensuring complete trust and transparency of companies ethical and sustainability.

Challenges we ran into

Back-end development faced challenges when implementing cryptographic signing and verification logic because it was hard to determine the errors inside the algorithm, so we had to manually read literature and documentation to find the solution. Additionally, we struggled with writing the front-end design, so under time restraints we opted for a simple black and white interface.

Accomplishments that we're proud of

Completing a clear chain of production, delivering transparency to consumers to empower more informed decisions in their day to day life. This lays the foundation to building a more sustainable, ethical, and efficient system.

What we learned

We learnt how to build a verifiable privacy backend FastAPI, producing a centralised hash-linked ledger with downloadable proofs.

What's next for Bober

Interfacing for Companies
