Web Task Execution System
The task execution system operates as an on-demand service:
Technical Implementation
Task representation: JSON-RPC over WebSockets
Execution sandbox: Chrome extension isolated context
Security boundary: Content Security Policy Level 3
Authentication: Digital signatures with time-based nonces
Fault tolerance: Automatic task reassignment after timeout
Click Data Collection System
The click data system operates passively during normal browsing:
Data Privacy Architecture
User identification: Zero-knowledge techniques prevent linking data to individuals
Differential privacy: Local statistical noise injection
Data minimization: Only essential interaction metrics stored (timestamp deltas, element types, navigation depth)
Cryptographic separation: k-anonymity for all submitted batches
Secure aggregation: Homomorphic encryption allows insights without exposing individual data
Blockchain Integration
The blockchain layer provides several critical functions:
Verification: Validates completed web tasks and data submissions
Point Distribution: Records and manages Browser Cash reward allocations
System Security: Ensures transparency and immutability of operations
Governance: Enables decentralized control of network parameters
Smart Contracts: Automates reward distribution and system operations
