Blockchain-Based Employment Verification System

Objective

To build a secure, transparent, and tamper-proof platform for verifying employment history and credentials using blockchain technology, enabling faster and more trustworthy hiring processes.

Key Features

Immutable Records: Employment data and credentials stored on a blockchain, cannot be altered.

Self-Sovereign Identity: Employees own and control access to their verified employment history.

Smart Contracts: Automate the verification process between employers, institutions, and candidates.

Instant Verification: Recruiters can instantly verify employment history without contacting past employers.

Access Control: Only authorized parties can view specific data using cryptographic permissions.

Technologies Used

Blockchain Platforms: Ethereum, Hyperledger Fabric, or Polygon

Smart Contract Language: Solidity (Ethereum) or Chaincode (Hyperledger)

Identity Management: Decentralized Identifiers (DIDs), uPort, or Sovrin

Storage: IPFS or off-chain encrypted databases with blockchain hashes

Frontend: React.js, Vue.js

Backend: Node.js, Express.js

Wallets: MetaMask, or custom DApp authentication

How It Works

User Registration: Employees and employers register on the platform with digital identity.

Data Submission: Employers upload employment records, signed and verified on-chain.

Credential Tokenization: Verified credentials are tokenized and linked to the employee’s digital identity.

Access Request: Recruiters or third parties request access to employment history.

Smart Contract Verification: Automatically checks data authenticity and access rights.

Audit Trail: All verifications are logged and timestamped immutably.

Benefits

Tamper-Proof Verification: Eliminates resume fraud and falsified job history.

Time & Cost Saving: No need to manually contact past employers.

Enhanced Trust: Employers can trust verified credentials with on-chain proof.

User Control: Individuals decide who can access their data.

Compliance Ready: Helps meet data protection and transparency standards (e.g., GDPR).
