# Audience Inventory

> The Asset Class of Attention

# The Asset

**Audience Inventory** is the end product of the 555x402 flywheel. It turns ephemeral "attention" into a durable, tradable asset.

## Technical Standard: cNFTs

We utilize **Compressed NFTs (cNFTs)** on Solana via the **Metaplex Bubblegum** program. This allows us to mint millions of inventory items for fractions of a penny, making high-volume attention tracking economically viable.

### Merkle Tree Structure

Inventory is stored in a concurrent Merkle Tree on-chain.

* **Max Depth**: 24 (16M items).
* **Canopy Depth**: 14 (Fast verification).

## Metadata Schema

Every unit of Audience Inventory adheres to a strict JSON schema, ensuring interoperability with advertisers. We enrich this data with **Social Context**.

```json theme={null}
{
  "name": "Sector 13 - Session #8821",
  "symbol": "555-INV",
  "description": "Verified gameplay session of Sector 13.",
  "image": "https://arweave.net/...",
  "attributes": [
    { "trait_type": "Game", "value": "Sector 13" },
    { "trait_type": "Duration", "value": "600" },
    { "trait_type": "Score", "value": "15420" },
    { "trait_type": "User Reputation", "value": "85" },
    { "trait_type": "Bot Probability", "value": "0.01" },
    { "trait_type": "Verified By", "value": "VAP Node 01" },
    // Social Context
    { "trait_type": "Streamer", "value": "@Ninja" },
    { "trait_type": "Platform", "value": "Twitch" },
    { "trait_type": "Viewer Count", "value": "15400" }
  ],
  "properties": {
    "files": [
      { "uri": "https://arweave.net/replay_data", "type": "application/json" }
    ]
  }
}
```

## Bespoke Targeting

Advertisers can use this rich metadata to buy **Verified Airtime** that matches their exact niche.

### 3. Utilization (Yield)

Advertisers do not manually "buy" individual items. Instead, they **plug in** to verified inventory sources programmatically.

1. **The Stream**: The Creator streams content, generating verified inventory (cNFTs).
2. **The Plug**: Advertisers set criteria (e.g., "Sector 13, >1000 viewers").
3. **The Yield**: When criteria match, the protocol **automatically routes** the ad to the stream.
4. **The Payout**: The Creator earns yield (USDC/\$555) instantly for every second of verified airtime.

**No manual sales. No negotiation. Just stream and earn.**

This allows brands to target **Micro-Communities** with surgical precision, paying creators directly for the quality of their audience, not just the quantity.

## Market Dynamics

* **Floor Price**: Determined by the "Cost of Attention" (e.g., \$0.01 per minute).
* **Rarity**: High-reputation users or high-score sessions command a premium.
* **Liquidity**: Inventory can be bundled and sold in bulk (e.g., "1000 hours of FPS gameplay").
