Decentralized Data Marketplace Protocol 📊

This protocol allows users to securely share and trade AI training data in exchange for $AIC token rewards.

📌 Key Features

• Data Ownership Protection – Users tokenize their datasets as NFT assets.

• Trusted Data Validation – AI-Chain leverages ZK-SNARK proofs to verify data authenticity.

• Smart Contract-Driven Transactions – Payments are automated via $AIC token-based escrow contracts.

📌 Solidity Smart Contract Example

pragma solidity ^0.8.0;

contract AIDataMarketplace {
    struct DataItem {
        string dataHash;
        address owner;
        uint price;
        bool purchased;
    }

    mapping(uint => DataItem) public dataListings;
    uint public itemCount;

    function listData(string memory _dataHash, uint _price) public {
        itemCount++;
        dataListings[itemCount] = DataItem(_dataHash, msg.sender, _price, false);
    }

    function purchaseData(uint _id) public payable {
        require(!dataListings[_id].purchased, "Data already purchased");
        require(msg.value >= dataListings[_id].price, "Insufficient funds");

        payable(dataListings[_id].owner).transfer(msg.value);
        dataListings[_id].purchased = true;
    }
}
