Workers can anonymously attest to a positive or negative experience with a employers address. Whenever there is unpaid wages a worker can attest a claim to a particular wallet address and also attest to fame for an employer where they have had a positive experience. The landing page is open to everyone where employer wallet addresses can be searched for claims and check if they are still open or if they have been revoked by the originator and are now closed.

Key Features:

• Anonymous Attestations: Workers can safely share their experiences without fear of retaliation.
• Dual Attestation Types:
  • Negative: Claims for unpaid wages
  • Positive: Recognition of good employer practices
• Public Search Function: Anyone can search for attestations linked to specific employer wallet addresses.
• Revocable Attestations: Workers can close or revoke their attestations once resolved, ensuring up-to-date information.
• Human Verification: Integration with WorldID to prevent bot-generated attestations.

Technical Stack:

• Blockchain: Optimism (Ethereum Layer 2 solution)
• Attestation Service: Ethereum Attestation Service (EAS)
• Identity Verification: WorldID

Technical Implementation:

1. Frontend:
   • User-friendly interface for submitting and searching attestations.
   • Integration with Web3 wallets for secure interactions.
2. WorldID Integration:
   • Implements WorldID's verification protocol to ensure human workers.
3. EAS Integration:
   • Utilizes EAS for creating and managing verifiable attestations on the blockchain.
4. Optimism Network:
   • Chosen for its low gas fees, making it cost-effective for workers to submit attestations.

How It Works:

1. User Registration:
   • Workers register using WorldID for human verification.
   • This step ensures one attestation per real human, preventing spam and false claims.
2. Creating an Attestation:
   • Workers can submit two types of attestations: a. Negative: Claims for unpaid wages, linked to the employer's wallet address. b. Positive: Recognition of good practices or positive experiences.
   • Each attestation is stored on the Optimism blockchain using EAS.
3. Searching Attestations:
   • The platform provides a public search function.
   • Workers can input an employer's wallet address to view all associated attestations.
   • Results show both open and closed attestations for a comprehensive view.
4. Managing Attestations:
   • Workers can revoke or close their claims if resolved.
   • This feature allows for resolution of disputes or updating outdated information.
5. Employer Interaction:
   • Employers can view attestations linked to their wallet address.
   • This transparency encourages fair practices and prompt resolution of issues.
