In addition, Chris World the Residence is utilizing its know-how in resort management and developing a platform that can be utilized anywhere in Korea and abroad without any barriers between countries by utilizing the blockchain distributed ledger method to enhance the security of customer information and travel (general, golf tours) / accommodation (domestic, overseas) reservation and customer management system based on this CWA project.

//pragma solidity ^0.8.0;

// Assume we have an imported ZKP library with a verifier contract interface
// import "./ZKPVerifierInterface.sol";

    // ZKPVerifierInterface public zkVerifier;

    // Example constructor that sets the ZKP verifier (could be a deployed contract address)
    // constructor(address verifierAddress) {
    //     zkVerifier = ZKPVerifierInterface(verifierAddress);
    // }

    // Function to verify a golfer's reservation using ZKP
    function verifyReservation(
        bytes32[] calldata _proof,
        uint256[] calldata _publicInputs,
        uint256[] calldata _privateInputs
    ) external returns (bool valid) {
        // Call the ZKP library's verify function
        // bool isValid = zkVerifier.verify(_proof, _publicInputs, _privateInputs);
        // require(isValid, "Invalid ZKP proof provided.");

        // If the proof is verified, we update the booking status
        // Here, _publicInputs could contain the reservation ID or timestamp
        // And we can emit an event or update the state accordingly
        if (valid) {
            // Update reservation status
            // emit ReservationConfirmed(_publicInputs[0]);

        return valid;

    // Additional functions to handle reservations might go here
    // For example, creating a reservation, canceling, etc.

By expanding business partnerships with various domestic and foreign resorts, hotels, and lodging companies, we will provide them with a service that enables them to securely book and manage their guests with a blockchain system, and provide customers with a trusted platform without security issues.

As the need for blockchain adoption by platform companies where user trust is a priority, especially in travel and luxury goods purchases, becomes more urgent, CWA will quickly capture the market and become the new leader in travel/hospitality booking and customer management platforms.

It will first apply blockchain technology to its loyalty program by leveraging the CWA token. It will provide a decentralized platform for travelers to track and redeem rewards as they are earned by various service providers. It will ensure the immutability of point balances, eliminate the risk of fraud, and enable real-time reward redemption and exchange.

Kiosks are equipped with distributed identity verification (DID) technology to enable contactless check-in. It prevents guests from providing excessive information at check-in, such as social security numbers and addresses, by verifying their age and identity. It also prevents the use of fake or altered IDs, ensuring a safe and convenient stay. In the future, we will also introduce contactless check-in kiosks using this technology.

Travel and hospitality platforms in particular are leveraging blockchain because they have a particularly high need for security and trust. Blockchain technology can help keep users safe by eliminating risks such as ticketing fraud and identity theft because they are recorded on a blockchain network that is physically impossible to hack. This reduces the fear of privacy breaches for customers. This will be a big draw for many potential customers.

Blockchain is a technology that adds trust to the existing internet and is a two-way file transfer system that allows all participants to share data containing sensitive information with each other without a centralized server. Each individual participant grows larger and larger, forming a network that becomes a distributed database, and this larger system becomes increasingly reliable, making each other's transactions safe.

Therefore, CWA has analyzed the existing online travel/flight/accommodation reservation system in various aspects such as structure, types, problems, and cases based on our operational experience, and is in the process of building a reservation/booking system that remodeled the reservation and ticketing parts based on the Ethereum network, which is the most reliable among the current blockchain public networks. This is expected to solve problems such as leakage of customer personal information that occurred in the existing accommodation/travel reservation and customer management system.

This innovative technology will expand rapidly as tokens can be used and transferred anywhere in the world without currency exchange, and most travel and hospitality companies in Korea and abroad will be eager to partner with CWA to gain more customer trust and marketing advantages.

Therefore, the CWA token, which will power the system (and will be used for both rewards, payments, contract transfers, and more), will appreciate in value.

We plan to add rewards systems and other features to ensure that CWA tokens are used in these ChrisWorlds booking systems (see the Yanolza-MilkCoin use case).
