At the heart of the system is the WorkContract, which manages the relationship between workers and employers. Each contract integrates with various modules to handle:
- Payments and escrow
- Work verification
- Grievance handling
- Compliance monitoring
- Survey management
- Reputation tracking
The WorkAgreementFactory serves as the main entry point for contract creation, providing:
- Template management for different work types
- Compliance requirement configuration
- Dispute settings management
- Stakeholder validation
- Initial deposit handling
The system features two complementary DAOs:
WorkerDAO
- Serves as a mutual aid society for workers
- Manages welfare fund and benefits
- Provides tiered membership (BASIC → ACTIVE → CORE → ELDER)
- Participates in dispute resolution
- Monitors compliance standards
EmployerDAO
- Focuses on arbitrator selection
- Maintains employer representation
- Conducts regular arbitrator elections
- Participates in compliance setting
- Manages employer reputation standards
The reputation registry provides comprehensive scoring with:
- Multiple scoring factors (completion, timeliness, quality, etc.)
- Stake-based reputation weighting
- Privacy controls for sensitive data
- Score decay over time
- Recovery mechanisms for low scores
- Appeal process for disputed ratings
- Minimum thresholds for contract participation
The grievance registry provides:
- Secure and private reporting channels
- Multi-stage resolution tracking (PENDING → IN_MEDIATION → RESOLVED/ESCALATED)
- Anonymous reporting options
- Evidence management
- Integration with arbitration
- AI-assisted resolution preparation
Monitors and enforces:
- Working hours and overtime
- Minimum wage requirements
- Rest period enforcement
- Age verification
- Insurance requirements
- Safety certifications
- Regular auditing
- Violation reporting
The system employs multiple oracle types:
- GPSOracle: Validates location and attendance
- ImageOracle: Processes visual evidence
- WeightOracle: Verifies quantity-based work
- TimeClockOracle: Manages time-based verification
- MultiOracle: Combines multiple verification methods
Supports multiple payment models:
- TimeBasedPayment: Hourly/shift-based work
- PieceRatePayment: Unit-based compensation
- MilestonePayment: Project-based deliverables
- CustomPayment: Hybrid payment structures
- Escrow management for payment security
- Dispute-triggered payment holds
Integrated survey system featuring:
- Industry-specific questionnaires
- Random question selection
- Privacy-preserving feedback collection
- Compliance monitoring
- Working condition assessment
- Anonymous reporting options
The system implements comprehensive interfaces:
- IWorkerDAO & IEmployerDAO: DAO interactions
- IOracle: Work verification
- IPaymentStructure: Payment handling
- IGrievanceRegistry: Grievance management
- ICompliance: Compliance monitoring
- IReputation: Reputation tracking
- IArbitration: Dispute resolution
- ISurvey: Feedback collection
- Role-based access control
- Stake requirements
- Privacy controls
- Reentrancy protection
- Secure fund management
- Evidence verification
- Proof validation
The workflow involves:
- Template Selection & Contract Creation
- Stakeholder Validation & Initial Setup
- Work Recording & Verification
- Payment Processing & Escrow
- Compliance Monitoring & Reporting
- Grievance Handling & Resolution
- Reputation Updates & Maintenance
- Survey Collection & Analysis
The modular design enables:
- Flexible verification methods
- Customizable payment structures
- Democratic governance
- Protected worker rights
- Systematic monitoring
- Efficient dispute resolution
- Privacy-preserving feedback
- Comprehensive compliance tracking
This comprehensive system creates a framework for fair work arrangements while maintaining transparency, protecting worker rights, and enabling efficient dispute resolution.
