ChainIn ⛓️

Authenticity-Driven, Privacy-Focused Business & Employment Aggregator dApp. Fostering genuine connections between employers and job seekers using Chainlink CCIP, Polygon ID, The Graph and Tableland.

🛑 Problem

The Web2 version of LinkedIn we have today contains several critical concerns:

  1. User Privacy - Users have to provide extensive personal information for e.g. in order to "complete" setting up a user profile, the user has to add in their birthday, which is completely unnecessary.
  2. Authenticity - LinkedIn struggles with fake profiles and inflated credentials, impacting trust and authenticity when viewing a user's profile, for e.g. users can easily endorse each other, leading to inflated profiles.
  3. Inconsistency - Job application process has also been criticized for its inconsistency, causing a cumbersome experience for users seeking to apply for positions.

💫 Solution

ChainIn is a secure and transparent space for businesses and job seekers, prioritizing user authenticity through verifications and proof of experience. 🌟

⛑️ How it works

ChainIn Demo Slides

  1. Connect your wallet through our built-in wallet provider, RainbowKit.
  2. Set up your profile.
  3. Voila! It's done. Your info stays on-chain, safe from leaks.

✨ Features

  1. 😌 Simple UI/UX: Users can personalize their profile with just a few pieces of information.

  2. 🔥 Permissionless NFTs: Creating an organization page will permissionlessly deploy an NFT smart contract that is unique to your organization.

  3. 🧑🏻‍💻 Seamless Listings: Creator of the organization can seamlessly create job listings for users to browse.

  4. 📲 Effortless Applications: Users can apply for jobs with the chosen organization with just a few clicks.

  5. 🧾 Proof-of-Experience: Users can add an organization to their profile and verify their authenticity through Polygon ID.

  6. 😉 Cross-chain Minting: Users upon proving their identity, can choose to mint their proof of experience on their selected destination chain.

  7. Gasless: Gas and most on-chain operations are abstracted from the user, prioritizing UI/UX.

🏛️ Architecture

🧑🏻‍💻 Software

  • Chainlink CCIP: We used Chainlink's CCIP to allow users to mint their proof-of-experience NFT on their selected destination chain. This provides versatility and enhanced UX for the user.

  • Polygon ID: We implemented Polygon ID to let users verify their credentials through ZK proofs from their wallet so that we can airdrop the user a verified NFT that can be used to verify their authenticity before minting an organization's proof-of-experience NFT to their wallet.

  • The Graph: We created a Subgraph to fetch the job applicant's data from the emitted event when a Job Application NFT has been minted. This allows job applicants to get confirmation of their successful application while providing the applicant's information to the employers.

  • Tableland: We wanted a permissionless SQL-like on-chain database. We used their Studio & Console clients, SDK, and CLI to create, store, test, and manage tables & queries. Tables are hosted on Polygon Mumbai.

🛠️ Improvements

  • Feature Enhancements:

    • Social Posts, Comments & Likes: Implement ChainIn's social network aspect to increase user engagement.
    • User Portfolio Enhancements: Add in features to the user profile page e.g. resume uploads, video introduction & showcase of user's verified NFTs.
    • Resume File Uploads in Subgraph: Include links to resume for employers to easily view job applicant's details.
    • Cross-chain Minting Choices: Increase DevOps to allow more network choices for cross-chain minting.
    • Additional Tools: Improve organization management tools to allow organization creators to better manage their organization page.
  • Latency Improvements:

    • Server-Side Optimization: Improve server response times to reduce front-end load.
    • Client-Side Efficiency: Improve UX and UI performance.
    • Framework Selection: Evaluate more efficient frameworks and technology stacks.
    • Caching with CDN
    • Micro API Optimization
  • Gasless Transactions: Gasless on-chain storing of data but at the cost of security.

⛔️ Limitations

  • Team Dynamics: We had to rework our team and find a new member mid-hackathon due to the inactivity and lack of participation of our previous front-end developer.

  • Team Constraints: Team of 3, each with full-time jobs, dedicating weekends and nights. We had to carefully plan for MVP and sacrifice certain requirements deemed secondary.
