The Reddcoin User ID system is a comprehensive identity management framework built on the Reddcoin blockchain. It creates a hierarchical naming system allowing users to register and manage human-readable identifiers. The system consists of three primary components:

• Namespaces: Top-level domains (like .redd)
• User IDs: Second-level identifiers within namespaces (like alice.redd)
• ReddIDs: Cross-namespace identities that tie multiple user IDs together

• Both namespaces and user IDs are allocated through competitive auctions
• Promotes fair price discovery and reduces squatting
• Creates deflationary pressure on RDD supply through burn mechanisms

• Namespaces establish rules and parameters for all user IDs within them
• Namespace owners receive a portion of user ID auction proceeds
• Different namespaces can have different character rules, pricing, and renewal policies

• ReddIDs provide consistent identity across multiple namespaces
• Reputation system tracks and scores user behavior
• Social connections enable follow/friend/endorse/block relationships

• Revenue from auctions is distributed among:
  • Burn pool (50-80%)
  • Namespace owners (5-10%)
  • Node operators (5-25%)
  • Development fund (5-15%)
• Renewal fees are based on name length, activity, and usage metrics
• Anti-squatting measures include progressive penalties and reclamation auctions

• Fully integrated with Reddcoin Core
• Uses OP_RETURN data structures for blockchain storage
• P2P protocol extensions for efficient message relay
• Comprehensive API and RPC interfaces for application integration

• Persistent digital identity across services
• Reputation-based trust for decentralized transactions
• Social network functionality with privacy controls
• Cross-namespace resolution for consistent identification

This system represents a significant advancement in blockchain-based identity management, providing both the technical infrastructure and economic incentives for sustainable digital identity within the Reddcoin ecosystem.
