==== 4.1.1 Private Proof of Stake ====

Description: The Base Layer MUST implement a Private Proof of Stake consensus mechanism that preserves validator privacy and prevents targeted attacks.

Functional Requirements:

PPOS-001: Validator Privacy
* The system MUST implement basic privacy:
** Hide validator stakes through Blend Network
** Preserve block proposer anonymity
** Prevent stake deanonymization attacks
** Maintain validator metadata privacy
* The system SHOULD support enhanced privacy:
** Advanced timing analysis protection
** Enhanced anonymity set generation
** Improved network attack resistance

PPOS-002: Consensus Security
* The system MUST provide basic security:
** Prevent stake grinding attacks
** Ensure fair block production
** Maintain consensus finality
** Handle network partitions
* The system SHOULD implement advanced security:
** Quantum attack resistance
** Eclipse attack prevention
** Advanced fork choice rules
** Complex partition handling

PPOS-003: Network Resilience
* The system MUST ensure basic resilience:
** Support commodity hardware validators
** Handle intermittent connectivity
** Recover from network failures
** Maintain liveness under attack
* The system SHOULD provide enhanced resilience:
** Advanced recovery mechanisms
** Dynamic attack mitigation
** Adaptive network topology
** Self-healing capabilities
