DeCAT- Decentralized identity and reputation system for revolutionizing the job market

[dhananjaypai08]

1. What is your project, and what problem does it solve? (max 100 words)

DeCAT aims to revolutionize credential management by leveraging Soulbound(Non transferrable NFT's) NFTs on Layer-2 Network(Polygon). This will address issues like forgery, duplication, and lack of trust in traditional certificates.
The platform offers:

• Unparalleled security: Soulbound NFTs ensure authenticity and uniqueness of achievements.
• Decentralized efficiency: L2 network promotes scalability and bulk minting via Multi batch transaction.
• Immutable records: Blockchain guarantees tamper-proof evidence of accomplishments.
• Enhanced trust and transparency: Verifiable credentials using QR codes improves the hiring and recruitment processes.

We are a B2B SaaS Platform which caters to educational institutions, professional bodies, HR departments, and individuals, offering a secure and reliable system for managing and showcasing achievements, ultimately impacting millions of learners and professionals.

The problem:

• Traditional certificate issuance and verification suffer from issues like duplication, forgery, and lack of trust.
• This undermines the value of achievements and creates difficulty in verifying individual skills during recruitment.
• Even in web2 and web3 systems certificates and important documents can be easily duplicated and forged.
• The verification system of credentials is Fragmented and no Unified method of verification and issuance is possible with high security.
• Organizations waste a lot of time, drive space for generating and distributing certificates for their attendees.

3. a) How is IPFS, Filecoin, or related technology used in this project?

DeCAT theme is for Soul Bound Tokens which on a granular level is nothing but an NFT. To store the metadata which includes the JSON format of image-uri, name, description and other details we use IPFS http storage via the Lighthouse.storage sdk to store the data and also to retrieve the data using its own http gateway. Moving forward the use case for storing metadata and other onchain data would require heavy use case of Filecoin( For generating and verifying onchain ZKproofs). Lighthouse.storage has the simplest docs and the development process after generating api-keys for the lighthouse.storage SDK was smoother

b) Is this project building with the current microgrants focus area (FVM)? (Yes or No)

Yes

4. How will you improve your project with this grant? What steps will you take to meet this objective?

• Grant Amount and Breakdown

The MVP would approximately take 3 months to be built including research, testing, auditing, new features, etc.

• Fixed Cost
  • Server Cost: Deployment of Reactjs frontend and FastAPI server on 2 different ec2 instances - 600$ for at least 3 months =
    1800$
  • API proprietary: Using LLM API's and summarizing models by fine tuning it based on the already prevailing LLM models which are
    trained on billions of parameters - 150$Rs for 3 months = 450$
  • One time direct cost of Registering DeCAT as a private Limited Company - 200$
  • One time direct cost of Domain registration and DNS - 200$
  • Salaries of 1 developer for developing Account abstraction and UI - 400 for 3 months = 1200$
  • Marketing, PR and overhead cost - 500$ for 1 month = 500$
  • Total Fixed Cost = 4350$
• Variable Cost
  • Deploying Smart contract continuously in the development and testing phase for 3 months ~ Approx 50$
  • Auditing of smart contracts ~ Approx 300$
  • Total variable cost ~= 350$
• Total Cost = 4700$

Timeline	work
A month	Find existing bugs, extensive edge case handling, find vulnerabilities in the existing system and resolve those
Next month	Domain registration, SSL certificate generation, EC2 instance deployment for the improved prototype, testing and deployment of smart contract on polygon mainnet
Month after that	Integration of web3 social auth for smoother user onboarding, integrating account abstraction SDK for making it web2 friendly
Remaining days	continuation of account abstraction integration, moving from simple proofs to ZKproofs on-chain/off-chain(generating zk-proof based on the JSON metadata for qr-code and verifying this verifiable credential on our website), improving the off-chain capabilities via more exposed endpoints in FastAPI, improving UI based on organization feedback, catering to different organization requests and developing key business metrics to track the growth of beta version. And then finally releasing the MVP and looking to sustain via revenue and funds(if necessary)

5. If accepted, do you agree to share monthly project updates in this Github issue for 3 months or until the project described here is complete?

Yes

6. Does your proposal comply with our Community Code of Conduct?

Yes
