Schema Marketplace

Overview

FoldDB's Schema Marketplace enables developers to publish schemas that define data structures, field mappings, permissions, and payment requirements. The marketplace uses Lightning Network micropayments and trust-based pricing for schema development and usage.

        U3((User 3)) --> |Lightning Payment| S2

    subgraph Request
        U[User] --> |Query| S[Schema]
        S --> |Calculate| F[Fees]
        F --> |Generate| H[Hold Invoice]
    end
    subgraph Payment
        H --> |Lightning Network| P[Process]
        P --> |Verify| V[Validate]
        V --> |Complete| T[Transaction]
    end
    subgraph Distribution
        T --> |Base Fee| D[Developer]
        T --> |Trust Bonus| B[Trust Pool]
    end

• Lightning Network Integration

  • Micropayments
  • Hold invoices for operations
  • Trust-based fee scaling
  • Atomic transactions

• Pricing Factors

  • Base schema costs
  • Trust distance multipliers
  • Operation complexity
  • Resource usage

3. Trust System

graph TD
    subgraph Trust Relationships
        A[User A] -->|Trust Level 1 <br> Low Cost| B[User B]
        B -->|Trust Level 2 <br> Medium Cost| C[User C]
        A -->|Trust Level 3 <br> High Cost| C
    end
    subgraph Access Rights
        B --> |Full Access| S1[Schema 1]
        C --> |Limited Access| S1
        C --> |No Access| S2[Schema 2]
    end

• Trust-Based Access
  • Lower costs for trusted users
  • Broader access rights
  • Simplified permissions
  • Scaling

Schema Dependencies

Field Mapping Chain

graph TD
    subgraph Data Flow
        D((Raw Data)) --> |Field Map| S0{{Base Schema}}
        S0 --> |Field Map| S1{{Schema v1}}
        S1 --> |Field Map| S2{{Schema v2}}
        S2 --> |Field Map| S3{{Schema v3}}
    end
    subgraph Access Control
        U((Client)) --> |Query + Payment| S3
        S3 --> |Validated Access| U
        S2 --> |Restricted| X1((❌))
        S1 --> |Restricted| X2((❌))
        S0 --> |Restricted| X3((❌))
    end
