Editing Nomos/Requirements (section)

==== 4.1.3 Network and Consensus Privacy ====

Description: The Base Layer MUST implement two complementary privacy systems:

* Required for MVP:
** Nomos Blend Network: A specialized privacy system for Private Proof of Stake with three modules:
*** PTM (Persistent Transmission Module): Manages validator connections and drop messages
*** MBM (Message Blending Module): Processes consensus messages through mixing and timing obfuscation
*** CTM (Cover Traffic Module): Generates anonymity sets through cover messages
** libp2p-mix: A P2P networking module for general network privacy
* Future Enhancements:
** Advanced timing analysis protection
** Enhanced anonymity set generation
** Improved network attack resistance

Functional Requirements:

BNP-001: Persistent Transmission Module
* The system MUST maintain persistent validator connections with basic privacy:
** Establish and maintain secure validator connections
** Handle drop messages for connection privacy
** Monitor connection quality and health
** Manage connection lifecycles securely
* The system SHOULD implement advanced connection features:
** Dynamic connection management based on network conditions
** Enhanced privacy through adaptive drop message rates
** Advanced connection health monitoring and recovery
** Optimized connection resource management

BNP-002: Message Blending Module
* The system MUST process and blend consensus messages:
** Process consensus messages through mixing
** Implement basic timing analysis protection
** Integrate fully with Cryptarchia protocol
** Maintain message timing obfuscation
* The system SHOULD enhance message privacy:
** Advanced timing analysis protection mechanisms
** Enhanced message mixing algorithms
** Complex timing pattern obfuscation
** Optimized message processing and blending

BNP-003: Cover Traffic Module
* The system MUST generate minimum required cover traffic:
** Generate and maintain cover message streams
** Create sufficient anonymity sets
** Optimize resource usage for cover traffic
** Balance privacy and bandwidth usage
* The system SHOULD implement advanced cover traffic:
** Dynamic cover traffic generation based on network activity
** Enhanced anonymity set management
** Advanced traffic pattern obfuscation
** Efficient resource utilization strategies

BNP-004: Network Privacy Integration
* The system MUST provide network-level privacy:
** Network-level privacy for non-consensus messages
** Basic private P2P communication capabilities
** Private data dissemination mechanisms
** Basic traffic analysis protection
* The system SHOULD enhance network privacy:
** Advanced traffic analysis protection
** Optimized cover traffic generation
** Larger anonymity set maintenance
** Improved network attack resistance
