Overview​

This specification defines the marketplace infrastructure, economic models, and market mechanisms for component exchange in the Radium ecosystem.

Marketplace Infrastructure​

pub trait PaymentProcessor {
    async fn process_payment(&self, transaction: &Transaction) -> Result<PaymentResult>;
    async fn settle(&self, transaction_id: &TransactionId) -> Result<SettlementResult>;
}

Economic Models​

Pricing Mechanisms​

Pricing Models

pub enum PricingModel {
    Free,
    OneTime { amount: Amount },
    Subscription { monthly: Amount, yearly: Amount },
    UsageBased { per_use: Amount, tiers: Vec<UsageTier> },
    Freemium { free_tier: Tier, premium_tier: Tier },
    RevenueShare { percentage: f64 },
}

Dynamic Pricing

pub trait PricingEngine {
    fn calculate_price(&self, component: &ComponentId, context: &PricingContext) -> Amount;
    fn adjust_price(&mut self, component: &ComponentId, adjustment: PriceAdjustment) -> Result<()>;
}

Revenue Sharing Models​

Revenue Share Types

  • Platform fee (fixed percentage)
  • Tiered revenue share
  • Performance-based share
  • Subscription revenue share

Revenue Distribution

pub struct RevenueShare {
    pub platform_fee: f64,
    pub creator_share: f64,
    pub affiliate_share: Option<f64>,
    pub distribution: RevenueDistribution,
}

Subscription Systems​

Subscription Tiers

pub struct SubscriptionTier {
    pub name: String,
    pub price: Amount,
    pub features: Vec<Feature>,

}

pub struct TierLimits {
    pub component_access: ComponentAccess,
    pub api_calls: Option<u32>,
    pub storage: Option<u64>,
    pub support_level: SupportLevel,
}

Usage-Based Pricing​

Usage Metrics

Market Mechanisms​

Supply and Demand Dynamics​

Market Analysis

pub struct MarketAnalysis {
    pub supply: SupplyMetrics,

    pub quality_score: f64,
    pub popularity: f64,
    pub relevance: f64,
    pub recency: f64,
    pub user_rating: f64,
}
