Low-Altitude Computility Networks: RWA Tokenization for Aerial Edge Computing

2.1 Low-Altitude Economic Networks

LAENets represent dense networks of autonomous aerial nodes operating in lower airspace to provide logistics, communication, and sensing services. The Civil Aviation Administration of China has outlined plans to develop this sector, expanding drone logistics routes and urban air mobility services.

2.2 RWA Tokenization Fundamentals

Real-World Asset (RWA) tokenization involves representing physical assets as digital tokens on blockchain networks. This approach enables fractional ownership, transparent trading, and automated settlement of physical assets.

3.1 System Components

The Low-Altitude Computility Network (LACNet) architecture consists of four main layers:

• Physical Layer: Drones, eVTOLs, and ground stations with computing capabilities
• Blockchain Layer: Distributed ledger for token management and smart contracts
• Orchestration Layer: AI-driven resource allocation and task scheduling
• Application Layer: Urban services including logistics, surveillance, and edge computing

3.2 Tokenization Mechanism

Computing resources are tokenized as non-fungible tokens (NFTs) representing specific computational capabilities. Each token contains metadata about:

• Computing capacity (CPU/GPU performance)
• Available memory and storage
• Geographical location and mobility patterns
• Availability windows and pricing

4.1 Mathematical Framework

The resource allocation problem is formulated as an optimization maximizing overall network utility:

$\max \sum_{i=1}^{N} \sum_{j=1}^{M} x_{ij} \cdot u_{ij} - \lambda \cdot \sum_{i=1}^{N} c_i \cdot y_i$

Subject to:

$\sum_{j=1}^{M} x_{ij} \leq 1 \quad \forall i \in [1,N]$

$\sum_{i=1}^{N} x_{ij} \cdot r_{ij} \leq R_j \quad \forall j \in [1,M]$

Where $x_{ij}$ represents task assignment, $u_{ij}$ is utility, $c_i$ is computational cost, and $R_j$ is resource capacity.

4.2 Code Implementation

// Smart contract for computility tokenization
contract ComputilityToken is ERC721 {
    struct ComputeAsset {
        uint256 cpuCapacity;
        uint256 memory;
        uint256 storage;
        uint256 availability;
        address owner;
        uint256 pricePerCycle;
    }
    
    mapping(uint256 => ComputeAsset) public computeAssets;
    
    function mintToken(
        uint256 tokenId,
        uint256 cpu,
        uint256 memory,
        uint256 storage,
        uint256 price
    ) external {
        computeAssets[tokenId] = ComputeAsset(
            cpu, memory, storage, block.timestamp + 24 hours, msg.sender, price
        );
        _mint(msg.sender, tokenId);
    }
    
    function executeComputation(
        uint256 tokenId,
        uint256 cycles
    ) external payable {
        ComputeAsset storage asset = computeAssets[tokenId];
        require(msg.value >= cycles * asset.pricePerCycle, "Insufficient payment");
        require(block.timestamp <= asset.availability, "Resource unavailable");
        
        // Execute computation and transfer payment
        payable(asset.owner).transfer(msg.value);
    }
}
