RTA Protocol

Real-Time Assets (RTAs) are NFTs that acquire value in real-time through streaming activities. The RTA protocol is implemented through the integration of VibeFactory and PPM contracts.

​
Protocol Overview

RTAs represent vibestreams as ERC-721 tokens that generate revenue through time-based participation. Unlike traditional NFTs with static value, RTAs accumulate value through active streaming sessions.
RTAs are minted through VibeFactory and monetized via the PPM (Pay-Per-Minute) contract.

​
Core Mechanics

​
RTA Creation

RTAs are created through the VibeFactory.createVibestream() function: 
function createVibestream(
    string calldata mode,
    bool storeToFilecoin,
    uint256 distance,
    string calldata metadataURI,
    uint256 ticketsAmount,
    uint256 ticketPrice,
    bool payPerStream,
    uint256 streamPrice
) external returns (uint256 vibeId)

​
Real-Time Value Accrual

When payPerStream is enabled, the RTA generates value through:
  1. Participant Allowances: Users authorize spending for specific RTAs
  2. Time-Based Deductions: PPM contract deducts payments every 60 seconds
  3. Automatic Distribution: 80% to creator, 20% to treasury

​
RTA Data Structure

Each RTA contains the following immutable and mutable properties: 
struct VibeData {
    address creator;        // RTA creator (immutable)
    uint256 startDate;      // Creation timestamp (immutable)
    string mode;            // Stream mode (immutable)
    bool storeToFilecoin;   // Storage preference (immutable)
    uint256 distance;       // Geographic constraint (immutable)
    string metadataURI;     // Metadata URI (mutable)
    uint256 ticketsAmount;  // Ticket supply (immutable)
    uint256 ticketPrice;    // Ticket price (immutable)
    bool finalized;         // Finalization status (mutable)
    bool payPerStream;      // PPM enablement (immutable)
    uint256 streamPrice;    // Per-minute rate (immutable)
}

​
Payment Flow

1

Authorization

Participants call PPM.authorizeSpending() with tMETIS to create allowances for specific RTAs.
2

Stream Entry

Users call PPM.joinVibestream() to begin time-based payment processing.
3

Real-Time Deduction

PPM contract automatically deducts payments every 60 seconds while participants remain active.
4

Revenue Distribution

Payments are distributed immediately: 80% to RTA creator, 20% to treasury.

​
Value Accumulation Model

RTAs accumulate value through the following formula: 
RTA Value = Σ(participant_allowances × time_active × pay_per_minute_rate)
Where:
  • participant_allowances: Total authorized spending across all participants
  • time_active: Cumulative active streaming time
  • pay_per_minute_rate: Rate defined at RTA creation (in wei per minute)

​
Security Features

​
Per-RTA Isolation

Each RTA maintains isolated allowance tracking to prevent cross-contamination of funds.

​
Emergency Controls

  • PPM.emergencyStop(): Immediately removes participants from streams
  • Pausable functionality for system-wide halts
  • Maximum allowance limits (1000 tMETIS per transaction)

​
Gas Optimization

  • Minimum 60-second payment intervals prevent gas griefing
  • Batch payment processing for multiple participants
  • Gas-limited external calls (50,000 gas limit)

​
Integration Points

​
VibeFactory Integration

// RTAs with PPM enabled automatically register with PPM contract
if (payPerStream && streamPrice > 0) {
    IPPM(ppmContract).registerVibestream(vibeId, msg.sender, streamPrice);
}

​
VibeKiosk Integration

RTAs can simultaneously support both ticket sales and real-time streaming: 
// Dual monetization: tickets + streaming
createVibestream(
    mode,
    storeToFilecoin,
    distance,
    metadataURI,
    100,        // 100 tickets available
    0.1 ether,  // 0.1 tMETIS per ticket
    true,       // Enable PPM
    0.01 ether  // 0.01 tMETIS per minute
);
