2.2.4 Technical Implementation

class BlockchainMonitor {
    constructor(config) {
        this.apiEndpoint = config.apiEndpoint;
        this.wsEndpoint = config.wsEndpoint;
        this.queue = new Queue(config.maxQueueSize);
        this.cache = new Cache(config.cacheSize);
    }

    // Initialize WebSocket Connection
    async initializeConnection() {
        this.ws = new WebSocket(this.wsEndpoint);
        
        this.ws.onmessage = (event) => {
            const transaction = JSON.parse(event.data);
            if (this.validateTransaction(transaction)) {
                this.processTransaction(transaction);
            }
        };

        this.ws.onerror = this.handleConnectionError.bind(this);
    }

    // Transaction Validation
    validateTransaction(transaction) {
        return (
            transaction.confirmations >= this.minConfirmations &&
            transaction.amount >= this.minAmount &&
            this.isWhitelisted(transaction.address)
        );
    }

    // Movement Instruction Generation
    generateMoveCommand(transaction) {
        const hash = transaction.hash;
        const direction = this.hashToDirection(hash);
        return {
            direction,
            timestamp: Date.now(),
            transactionId: transaction.id
        };
    }

    // Hash to Direction Conversion
    hashToDirection(hash) {
        const value = parseInt(hash.slice(-2), 16);
        const directions = ['up', 'right', 'down', 'left'];
        return directions[value % 4];
    }
}

// Queue Manager
class Queue {
    constructor(maxSize) {
        this.maxSize = maxSize;
        this.items = [];
    }

    enqueue(item) {
        if (this.items.length >= this.maxSize) {
            this.items.shift(); // Remove oldest instruction
        }
        this.items.push(item);
    }

    dequeue() {
        return this.items.shift();
    }

    peek() {
        return this.items[0];
    }
}
