🔍 Verification System

Multi-Layer Verification Architecture

The platform implements a comprehensive three-layer verification system to ensure content authenticity and prevent fraud.

Layer 1: Automated Backend Verification

Process Flow:

1. User uploads video URL to create token
2. Backend service automatically triggered via blockchain events
3. YouTube API integration checks video metadata
4. Cryptographic challenge generated for ownership proof
5. Backend monitors for challenge completion
6. Verification result signed and submitted to blockchain

Verification Checks:

• URL Validity: Ensures YouTube URL is accessible and valid
• Metadata Analysis: Extracts and validates video title, description, tags
• Channel Verification: Checks channel authenticity and subscriber count
• Upload Date: Compares video upload date with token creation
• Ownership Proof: Requires cryptographic challenge in video description

Implementation:

class BackendVerificationService {
    async verifyVideoToken(tokenHash, youtubeUrl, ownerWallet) {
        try {
            // Step 1: Basic URL validation
            const videoData = await this.fetchYouTubeData(youtubeUrl);
            if (!videoData) {
                return this.submitVerification(tokenHash, false, "Invalid YouTube URL");
            }
            
            // Step 2: Generate ownership challenge
            const challenge = this.generateChallenge(ownerWallet, youtubeUrl);
            await this.storeChallenge(tokenHash, challenge);
            
            // Step 3: Check for challenge in description
            const hasChallenge = await this.checkForChallenge(youtubeUrl, challenge);
            if (!hasChallenge) {
                return this.scheduleRetry(tokenHash, 30000); // Retry in 30 seconds
            }
            
            // Step 4: Additional verification checks
            const verificationResult = await this.performDetailedChecks(videoData);
            
            // Step 5: Submit result to blockchain
            return this.submitVerification(tokenHash, verificationResult.approved, verificationResult.reason);
            
        } catch (error) {
            console.error('Verification failed:', error);
            return this.submitVerification(tokenHash, false, `Verification error: ${error.message}`);
        }
    }
    
    generateChallenge(wallet, url) {
        const timestamp = Date.now();
        const nonce = crypto.randomBytes(16).toString('hex');
        return `VERIFY_${keccak256(wallet + url + timestamp + nonce).substring(0, 12)}`;
    }
    
    async performDetailedChecks(videoData) {
        const checks = {
            channelVerified: videoData.channel.verified,
            subscriberCount: videoData.channel.subscriberCount > 1000,
            videoQuality: videoData.definition === 'hd',
            contentType: this.isMusic(videoData.title, videoData.description),
            uploadRecency: this.isRecentUpload(videoData.publishedAt),
            duplicateCheck: await this.checkForDuplicates(videoData.id)
        };
        
        const score = Object.values(checks).filter(Boolean).length;
        const approved = score >= 4; // Require at least 4/6 checks to pass
        
        return {
            approved,
            reason: this.generateVerificationReason(checks, score),
            score
        };
    }
}

Layer 2: Community DAO Verification

Governance Model:

• Reputation-based voting system
• Vote weight determined by user history and stake
• Multiple voting categories (authenticity, quality, spam)
• Quorum requirements for decision validity

Voting Categories:

1. Authenticity Vote: Is this really the claimed artist?
2. Quality Vote: Is this high-quality music content?
3. Spam Vote: Is this spam or low-effort content?
4. Originality Vote: Is this original content or a copy?

Reputation System:

class ReputationManager {
    calculateVotingPower(userAddress) {
        const factors = {
            accountAge: this.getAccountAge(userAddress),        // 0-25 points
            successfulVotes: this.getVoteAccuracy(userAddress), // 0-30 points
            tokenHoldings: this.getTokenStake(userAddress),     // 0-25 points
            communityScore: this.getCommunityScore(userAddress) // 0-20 points
        };
        
        return Math.min(100, Object.values(factors).reduce((a, b) => a + b, 0));
    }
    
    async updateReputationAfterVote(voterAddress, tokenHash, votedCorrectly) {
        if (votedCorrectly) {
            await this.increaseReputation(voterAddress, 1);
        } else {
            await this.decreaseReputation(voterAddress, 0.5);
        }
    }
}

Layer 3: User Self-Verification

Direct Verification Tools:

• One-click YouTube access from token page
• Verification checklist for users
• Risk assessment calculator
• Community comments and reviews

User Verification Checklist:

const VerificationChecklist = ({ youtubeUrl, tokenData }) => {
    const [checks, setChecks] = useState({
        urlAccess: false,
        channelMatch: false,
        verificationCode: false,
        contentQuality: false,
        uploadDate: false
    });
    
    return (
        <div className="verification-checklist">
            <h3>🔍 Verify This Token Yourself</h3>
            <a href={youtubeUrl} target="_blank" className="youtube-link">
                🎬 Open YouTube Video
            </a>
            
            <div className="checklist">
                <CheckItem 
                    label="Video loads and plays correctly"
                    checked={checks.urlAccess}
                    onChange={(checked) => updateCheck('urlAccess', checked)}
                />
                <CheckItem 
                    label="Channel name matches claimed artist"
                    checked={checks.channelMatch}
                    onChange={(checked) => updateCheck('channelMatch', checked)}
                />
                <CheckItem 
                    label="Verification code found in description"
                    checked={checks.verificationCode}
                    onChange={(checked) => updateCheck('verificationCode', checked)}
                />
                <CheckItem 
                    label="High-quality music content"
                    checked={checks.contentQuality}
                    onChange={(checked) => updateCheck('contentQuality', checked)}
                />
                <CheckItem 
                    label="Upload date matches token creation"
                    checked={checks.uploadDate}
                    onChange={(checked) => updateCheck('uploadDate', checked)}
                />
            </div>
            
            <TrustScore checks={checks} tokenData={tokenData} />
        </div>
    );
};

Verification Data Transparency

All verification data is stored on-chain and publicly accessible:

function getVerificationDetails(bytes32 tokenHash) external view returns (
    bool backendChecked,
    bool backendApproved,
    string memory backendReason,
    uint256 daoApprovalVotes,
    uint256 daoRejectVotes,
    uint256 qualityScore,
    uint256 totalVotes
) {
    VideoToken storage token = tokens[tokenHash];
    return (
        token.backendChecked,
        token.backendApproved,
        token.backendReason,
        token.daoApprovalVotes,
        token.daoRejectVotes,
        token.qualityScore,
        token.daoApprovalVotes + token.daoRejectVotes
    );
}

Pricing Mechanism

Initial Price Discovery

class PricingEngine {
    calculateInitialPrice(tokenData) {
        const factors = {
            channelSubscribers: this.getSubscriberMultiplier(tokenData.channelSubs),
            videoViews: this.getViewsMultiplier(tokenData.views),
            verificationScore: this.getVerificationMultiplier(tokenData.verificationScore),
            qualityScore: this.getQualityMultiplier(tokenData.qualityScore),
            marketDemand: this.getMarketDemand(tokenData.category)
        };
        
        const basePrice = 0.001; // ETH
        const multiplier = Object.values(factors).reduce((a, b) => a * b, 1);
        
        return basePrice * multiplier;
    }
    
    getSubscriberMultiplier(subs) {
        if (subs > 10000000) return 5.0;      // 10M+ subscribers
        if (subs > 1000000) return 3.0;       // 1M+ subscribers
        if (subs > 100000) return 2.0;        // 100K+ subscribers
        if (subs > 10000) return 1.5;         // 10K+ subscribers
        return 1.0;                           // Less than 10K
    }
}

Dynamic Pricing

• Bonding Curve: Price increases with demand
• Verification Premium: Verified tokens trade at premium
• Quality Bonus: High-quality scores increase value
• Scarcity Factor: Limited supply drives price discovery

Revenue Distribution

contract RevenueDistribution {
    struct RevenueShare {
        address creator;
        uint256 creatorShare;    // 70% default
        uint256 platformShare;   // 20% default  
        uint256 communityShare;  // 10% default
    }
    
    function distributeRevenue(bytes32 tokenHash, uint256 amount) external {
        RevenueShare memory shares = revenueShares[tokenHash];

Input Validation

class InputValidator {
    validateYouTubeURL(url) {
        const patterns = [
            /^https:\/\/www\.youtube\.com\/watch\?v=[\w-]+/,
            /^https:\/\/youtu\.be\/[\w-]+/,
            /^https:\/\/youtube\.com\/watch\?v=[\w-]+/
        ];
        
        return patterns.some(pattern => pattern.test(url));
    }
    
    sanitizeInput(input) {
        return input
            .replace(/[<>]/g, '')
            .trim()
            .substring(0, 1000); // Max length limit
    }
}

Attack Prevention

Common Attack Vectors & Mitigations

1. Duplicate Token Creation

   • Mitigation: Unique hash system (wallet + URL)
   • Check: require(tokens[hash].owner == address(0))

2. Fake Verification

   • Mitigation: Cryptographic signatures from backend
   • Verification: Signature recovery and validation

3. Vote Manipulation

   • Mitigation: Reputation-based voting weights
   • Detection: Anomaly detection in voting patterns

4. Front-running

   • Mitigation: Commit-reveal voting scheme
   • Protection: Time delays for high-value transactions

For Content Creators

1. Wallet Connection

   // Connect wallet using MetaMask or WalletConnect
   const connectWallet = async () => {
       if (typeof window.ethereum !== 'undefined') {
           await window.ethereum.request({ method: 'eth_requestAccounts' });
           const provider = new ethers.providers.Web3Provider(window.ethereum);
           const signer = provider.getSigner();
           return await signer.getAddress();
       }
   };

2. Content Upload
