Subject: Blockchain Ticketing Economic Model Simulation (TicketConnect v1)

System Description: I need to model a circular economy for an NFT ticketing platform on Polygon using USDC. The model must simulate two distinct phases: Primary Sales (Off-chain) and Secondary Sales (On-chain).

1. Resources & Entities:

Resource: USDC (Stablecoin).

Actor A: Platform Owner (Me).

Actor B: Event Organizer.

Actor C: Primary Buyers.

Actor D: Secondary Buyers / Sellers.

Asset: Ticket NFTs (unique, limited supply).

2. State Nodes & Logic (The Flow):

Primary Sale Loop (Off-chain):

Source: Primary Buyers.

Flow: 100% of Ticket Price → Platform Wallet.

Trigger: Backend verifies payment → Mints NFT to Buyer.

Constraint: Platform holds 100% of funds (Account for manual distribution to Organizers if applicable).

Secondary Market Loop (On-chain - Atomic):

Seller: Sets USDC_PRICE.

Buyer: Sends USDC_PRICE to Smart Contract.

Distribution Logic:

Platform_Fee = Price * 0.08 (8% fixed).

Seller_Proceeds = Price - Platform_Fee.

Friction: Deduct 0.05% from Platform_Fee as estimated Gas Cost for the transaction.

Hard Limit: If Platform_Fee 20%, transaction reverts (Hardcoded Constraint).

3. Token Lifecycle States:

State 1: Active (Transferable).

State 2: Redeemed (Boolean: True).

Effect: Transition to Non-Transferable (Dead End).

State 3: Attended (Boolean: True).

Effect: Metadata update only.

4. Simulation Goals:

KPI 1: Track "Platform Revenue" purely from Secondary Sales vs. Operational Costs.

KPI 2: Analyze "Scalper Profit" – how much a reseller makes after 8% fee.

Stress Test: Simulate a "Diamond Hands" scenario where secondary volume is 5% of total supply. Show the impact on Platform ROI.

5. Variables for Testing:

Primary_Ticket_Price: 50 USDC.

Secondary_Market_Markup: 1.2x to 3x.

Resale_Velocity: 10% of total tickets resold.
