  Dashboard; no groups created yet

Inspiration

My family practices a tradition called sou-sou, popular in Caribbean and African communities. This involves family members and friends with strong trust contributing money to a group fund every week for a cycle.

Every contributor is designated a week to withdraw a specific portion from the fund. This is called a 'hand'. Each group has a 'captain' is in charge of maintain a fair and smooth sou-sou round.

When a member has a turn to withdraw from the fund, they can either withdraw or save their hand to their next withdrawal turn.

Keeping track of this process can become tedious for the captain and group members, so I wanted to build a web app that can simplify this process.

What it does

It's an admin dashboard that allows the group captain to manage the fund using a cryptocurrency I created called: SOU-SOU.

The captain can create a group with the number of members, the length of the cycle and the weekly amount each person will contribute to the fund.

The dashboard displays:

• Which week in the cycle it is
• The current balance of the fund
• A table outline each weeks info

How I built it

I designed it using ExcaliDraw.com to sketch out my initial ideas and layout.

Since I chose ChakraUI for my front-end, I used OpenChakra.app to build out my website components, which sped up the dev process significantly. I also used NextJS to build the front-end.

I used Domain.com to find and purchase my domain name.

For hosting, I used Vercel and Google Firebase as my database.

I integrated Hedera Hashgraph's Token Service to create my own cryptocurrency.

Challenges I ran into

I has trouble integrating Firebase and Hedera Hashgraph Javascript SDK. So it just submits the use form.

Accomplishments that I'm proud of

Learning what blockchain technology is and I'm also proud about building a product with technology that I had no experience using before SheHacks.

What I learned

The differences between a blockchain data structure and a directed acrylic graph(DAG). How speed and low cost of transactions makes Hedera Hashgraph stand out among other cryptocurrency technology.

What's next for Our Sou-Sou

Figure out how to get Firebase working and Hedera Hashgraph for manage credits within the app. I would also like to add a feature that allows users to purchase SOU-SOU credits, so the group fund can be managed at a lower cost.
