• Extended Format Broadcasting - Backend handles network submission

• Atomic Context Sharing - Topic Managers provide atomic shared state

🎯 Topic Manager for Atomic Operations

Topic Managers handle atomic operations with shared context while maintaining atomic properties.

Atomic Topic Management

// Atomic Topic Manager - handles atomic operations with shared context
class AtomicTopicManager {
  
  // Process atomic topic updates
  async processAtomicTopicUpdate(beefHex: string, topic: string) {
    // Parse BEEF transaction
    // const beefTx = Transaction.fromHexBEEF(beefHex);
    
    // Validate BEEF structure and SPV proofs
    // const isValid = await beefTx.verify(this.chainTracker);
    // if (!isValid) {
    //   throw new Error('Invalid BEEF transaction for topic update');
    // }
    
    // Check if transaction is relevant to topic
    // const isRelevant = await this.validateTopicRelevance(beefTx, topic);
    // if (!isRelevant) return;
    
    // Apply atomic state transition for topic
    // await this.applyAtomicTopicTransition(beefTx, topic);
    
    // Notify subscribers of atomic state change
    // await this.notifyAtomicSubscribers(topic, beefTx);
    
    // Convert to Extended Format for network broadcasting
    // const extendedFormat = beefTx.toHexEF();
    // await this.broadcastToNetwork(extendedFormat);
    
    // All operations succeed or fail atomically
  }
  
  // Apply atomic state transition for topic
  private async applyAtomicTopicTransition(beefTx: Transaction, topic: string) {
    // Get current topic state
    // const currentState = await this.getTopicState(topic);
    
    // Calculate new state based on atomic transaction
    // const newState = this.calculateAtomicStateTransition(currentState, beefTx);
    
    // Apply new state atomically
    // await this.setTopicState(topic, newState);
    
    // State transition is atomic - no partial updates
    // Either complete success or complete failure
  }
  
  // Subscribe to atomic topic updates
  async subscribeToAtomicTopic(topic: string, callback: AtomicTopicCallback) {
    // Register callback for atomic topic updates
    // const subscription = {
    //   topic: topic,
    //   callback: callback,
    //   atomicOnly: true // Only atomic operations
    // };
    
    // Add to subscription list
    // this.subscriptions.set(topic, subscription);
    
    // Callback will be invoked for each atomic topic update
    // No partial state updates - only complete atomic transitions
  }
  
  // Get current atomic topic state
  async getAtomicTopicState(topic: string) {
    // Retrieve current atomic state for topic
    // const state = await this.topicStateStore.get(topic);
    
    // State is always consistent due to atomic updates
    // No coordination needed to read state
    // return state;
  }
}

Atomic Multi-Topic Operations

// Handle atomic operations across multiple topics
class AtomicMultiTopicManager {
  
  // Process atomic operation affecting multiple topics
  async processMultiTopicAtomicOperation(beefHex: string, topics: string[]) {
    // Parse BEEF transaction
    // const beefTx = Transaction.fromHexBEEF(beefHex);
    
    // Validate BEEF for all affected topics
    // for (const topic of topics) {
    //   const isRelevant = await this.validateTopicRelevance(beefTx, topic);
    //   if (!isRelevant) {
    //     throw new Error(`Transaction not relevant to topic: ${topic}`);
    //   }
    // }
    
    // Apply atomic state transitions to all topics
    // const stateTransitions = [];
    // for (const topic of topics) {
    //   const currentState = await this.getTopicState(topic);
    //   const newState = this.calculateStateTransition(currentState, beefTx);
    //   stateTransitions.push({ topic, newState });
    // }
    
    // Apply all state transitions atomically
    // await this.applyAtomicMultiTopicTransitions(stateTransitions);
    
    // Notify all topic subscribers atomically
    // await this.notifyMultiTopicSubscribers(topics, beefTx);
    
    // All topics updated atomically - no coordination needed
  }
  
  // Apply atomic transitions to multiple topics
  private async applyAtomicMultiTopicTransitions(transitions: TopicTransition[]) {
    // All topic state transitions happen atomically
    // Either all succeed or all fail
    // for (const transition of transitions) {
    //   await this.setTopicState(transition.topic, transition.newState);
    // }
    
    // No coordination protocols needed
    // Atomic semantics handle consistency
  }
}

🗂️ Basket Manager for Atomic Token Operations

Basket Managers organize tokens for atomic operations while maintaining atomic properties.

Atomic Basket Management

// Atomic Basket Manager - organizes tokens for atomic operations

  }
  
  // Organize tokens for atomic operations
  async organizeForAtomicOperation(requiredTokens: TokenRequirement[]) {

    // };
  }
  
  // Atomic inventory management using baskets
  async manageInventoryAtomically(inventoryOperation: InventoryOperation) {
    // Each inventory item is a token in a basket
    // Atomic operations prevent overselling mathematically
    
    // Get available inventory tokens
    // const availableTokens = await this.getTokensFromBasket(
    //   inventoryOperation.productBasket,

    // All baskets updated atomically
    // No coordination between basket operations needed
  }
  
  // Atomic marketplace using cross-basket operations
  async atomicMarketplaceOperation(marketplaceOp: MarketplaceOperation) {
    // Atomic asset purchase across baskets
    // - Asset moves from seller basket to buyer basket
    // - Payment moves from buyer basket to seller basket
    // - All happens atomically - no coordination needed
    
    // Prepare cross-basket operation
