Nodes

Every entity in the ƒXYZ network exists as a validated node with temporal relationships, privacy controls, and dynamic properties. The Knowledge Graph represents three primary node types, each with distinct capabilities and roles within the ecosystem.

​

Node Types

​

Human Nodes

Individuals and entities with decentralized identities, multi-chain wallets, and dynamic reputation systems.

​

Identity & Authentication

• DIDs: Decentralized identifiers for sovereign identity
• Linked Wallets: Multi-chain wallet connections (Solana, Ethereum, Bitcoin)
• Dynamic NFTs: Reputation tokens that evolve with network contributions
• Privacy-Preserving KYC: Verification through zero-knowledge proofs

​

Reputation & Validation

• Peer Validation: Community-driven verification processes
• Behavioral Tracking: Positive/negative attributes through graph relationships
• Historical Analysis: Temporal transaction patterns using Solana PoH
• Network Participation: Contribution weight and influence in network decisions

​

Fixies (Digital Agents)

Autonomous AI agents that operate across the network with specific capabilities and permissions.

​

Agent Types

• Personal Fixies: Individual member agents with private data access
• Public Fixies: Community query agents for general network information
• On-premise Fixies: Private installation agents for sensitive operations
• Validation Fixies: Network integrity agents for automated verification

​

Capabilities

• Graph Observation: Pattern detection and anomaly identification
• Data Validation: Cross-reference verification and consistency checking
• Privacy Management: User data sharing controls with granular permissions
• Learning & Adaptation: Continuous improvement through interaction patterns

​

Financial Entities

Institutional nodes representing traditional and digital financial infrastructure.

​

Institution Types

• Banks: Traditional and digital banking entities with API integrations
• Exchanges: Centralized and decentralized trading platforms
• Stablecoin Issuers: USDC, USDT, and other stable value token providers
• Central Banks: CBDC issuers and monetary policy entities

​

Network Integration

• API Connections: Real-time data feeds for rates and liquidity
• Liquidity Provision: Market making and arbitrage opportunities
• Compliance Monitoring: Regulatory adherence and reporting
• Risk Assessment: Credit scoring and counterparty analysis

​

Node Roles & Permissions

​

Reputation-Based Access

Node permissions and capabilities are determined by reputation scores, validation history, and network contribution patterns rather than fixed hierarchies.

Core Access Levels:

• Network Observer: Basic read access to public graph data
• Network Participant: Transaction and interaction capabilities
• Network Validator: Peer validation and verification authority
• Network Contributor: Governance participation and proposal creation

​

Dynamic Permissions

• Reputation Thresholds: Access levels adjust based on network reputation
• Skill-Based Roles: Specialized permissions for specific capabilities
• Temporal Access: Time-based permissions for specific operations
• Collective Validation: Community-verified role assignments

​

Privacy Architecture

​

Public Layer

Information visible to the network and external observers:

• Reputation score and public achievements
• Public transaction history (non-confidential)
• Governance votes and participation
• Knowledge contributions and validations

​

Private Layer

Information controlled by individual nodes through Fixie agents:

• Confidential token balances (ElGamal encrypted)
• Private network membership and communications
• Sensitive transaction details and relationships
• Personal agent data and preferences

}

​

Relationship Types

​

Financial Relationships

• VALIDATES: Peer validation and verification
• HOLDS: Token balances and asset ownership
• TRANSFERS: Transaction relationships with temporal data
• PROVIDES_LIQUIDITY: Market making and exchange facilitation

​

Governance Relationships

• PARTICIPATES_IN: Network and DAO participation
• ENDORSES: Peer recommendations and reputation
• PROPOSES: Governance proposal creation and sponsorship
• VOTES_FOR/AGAINST: Decision participation with weight

​

Knowledge Relationships

• CONTRIBUTES: Knowledge base additions and improvements
• REVIEWS: Peer review and validation activities
• LEARNS_FROM: Educational relationships and mentorship
• TEACHES: Knowledge transfer and skill development

​

Dynamic Relationship Evolution

Every interaction, transaction, and governance action creates temporal relationships stored immutably with Solana Proof-of-History timestamps. This enables:

• Historical Analysis: Understanding how relationships evolved over time
• Trend Detection: Identifying patterns in node behavior and network growth
• Causal Inference: Determining cause-effect relationships in network events
• Predictive Modeling: Forecasting node evolution and network development

​

Implementation Notes

• Graph Writes: All node mutations include Solana PoH slot numbers for ordering
• Privacy Controls: Fixie agents manage data visibility per user preferences
• Reputation Updates: Real-time calculation based on weighted peer endorsements
• Role Advancement: Automated validation through smart contracts

The node system creates a rich, dynamic representation of the ƒXYZ network that balances transparency with privacy, enabling sophisticated financial operations while maintaining decentralized governance.
