Cryptionary

Sample Homescreen. Users have the option of connecting their wallet, making a post, or guessing on an image.

Inspiration

While the use cases for web3 expand every day from healthcare to polling systems, we wanted to explore the implementation of web3 in the entertainment sector. As the world of cryptocurrency expands, people would want to play games using crypto and win crypto.

What it does

The user gets to draw a picture and set the answer for the picture. The other players can then try to guess the answer. If they get it right, they are rewarded with crypto. In order to guess, the player needs to put in some crypto. As a result, the prize pool for that particular picture increases. The artist will get a portion of the prize pool as an incentive for drawing.

How we built it

To start off we used Solana's Twitter example and other social media-on-the-block-chain implementations we found online. Through that, we were able to set up creating a wallet on our local machines that could be used to test functions. Our next issue was uploading an image to the blockchain so that the data itself was de-centralized. We used IPFS for this task but ran into issues while connecting the uploading API to the function for creating a post. For our front end we had to flip-flop between React and Vue, as Due was already connected to our backend and could be used to fetch data, however, our team felt more comfortable in using React for front-end development.

Challenges we ran into

We ran into some challenges in building the blockchain and saving the drawn image. Moreover, the time crunch was also a big challenge for us. While we were able to learn many individual technologies like creating a wallet on our local machine, uploading images with IPFS, and sending posts through the blockchain combining all those elements together with our front end is what posed an issue in the constrained timings. Another problem was picking technologies. For our front end, React was a framework most of use were accustomed to however, Vue was better integrated without backend calls and for getting the drawing of our user.

Accomplishments that we're proud of

We are proud that we were able to learn and overcome so many challenges in a short period of time. Despite it having been 24 hours it feels like we have gained decent experience in Web3 and Solana specifically.

What we learned

None of us had ever worked on web3 before. This was our first time developing a decentralized application (dapp). We also learned about the various use cases of Web3 and its advantages. Furthermore, we explored building smart contracts.
