Project Description

How It Works:

  • Connecting Wallet and Depositing Cryptocurrency: Users are required to connect their wallets to the platform. This ensures transparency and security throughout the feedback process. To request feedback, users need to deposit a certain amount of our native cryptocurrency, let's call it "DesignCoin," into their account.

  • Submitting Design for Feedback: Once connected and with DesignCoins deposited, users can post their designs by uploading relevant image(s) of their project. Each design post has a predefined validity period during which feedback can be given.

  • User-Friendly Interface: Our platform features an intuitive and user-friendly front-end interface inspired by popular design tool FIGMA. Users can easily navigate and interact with the platform, making the feedback process seamless.

  • Providing Feedback: To give feedback, users simply need to connect their wallets and add comments directly on the image. By clicking on specific areas of the design, users can pin their comments to provide precise feedback on particular elements.

  • Voting System: Users have the ability to vote on feedback and comments provided by others. This fosters engagement and helps identify the most helpful and valuable insights. The feedback and comments with the highest votes gain prominence on the platform.

Distribution of Rewards: At the end of the validity period, the top five users with the most votes on their feedback/comments will receive a share of the reward pool. The reward pool is composed of the DesignCoins deposited by users when posting their designs. This incentivizes active participation and motivates users to provide thoughtful and constructive feedback.

How it's Made

  • Blockchain Integration: The application is built on the @polygon network and using The Graph to interact with the smart contract.
  • We utilized Filecoin to store the design images and related information securely.
  • Used Ape Coin for deposit and rewards
  • Authentication and Identity: To enhance security and prevent misuse, we implemented Lens Protocol for user authentication and profile creation. Users must sign in and connect their wallets to post and comment on designs. This ensures accountability and maintains the quality of interactions within the platform.
