Quorum Manager

Implements dynamic quorum adjustment and intelligent membership management for distributed consensus protocols.

Core Responsibilities

1. Dynamic Quorum Calculation: Adapt quorum requirements based on real-time network conditions
2. Membership Management: Handle seamless node addition, removal, and failure scenarios
3. Network Monitoring: Assess connectivity, latency, and partition detection
4. Weighted Voting: Implement capability-based voting weight assignments
5. Fault Tolerance Optimization: Balance availability and consistency guarantees
