• Can crypto projects help reduce carbon foot print and **make the world a better place?**

What it does

  • COzA is short for Co2 Awareness
  • Raise awareness of eco-friendly crypto projects, such as StepN, SleepN, StatesDAO (because when you’re learning, you’re not producing CO2), and more.
  • User guesses how much Co2 carbon foot print is reduced by crypto services. And our gamification mechanism rewards them with Awareness-Tokens (AWA). Which will also serve as governance token in the future.

How we built it

  • We used GraphQL to fetch StepN data from BNB Chain blockchain.
  • We minted AWA Token on Near protocol.
  • We used Nest.js to connect the client and NEAR protocol and used React to make the front end.

Challenges we ran into

  • Since it was our first time using NEAR and Graph/Subgraph, we had some learning curve getting used to its functionalities and troubleshooting, especially minting out token in NEAR.

Accomplishments that we're proud of

  • A user who engages with our guessing game earns a AWA Token (Awareness Token).
  • Gamification via Guess-to-earn.

What we learned

  • Hackathon is fun, stressful but interesting.
  • We had fun getting to know more about NEAR and Graph technologies. We spent meaningful time learning more about the importance of Co2 emission and how it's everyone's problem to fix.

What's next for COZA

Further integration with various Co2 reducing crypto projects and AWA token Tokenomics.
