## Technical Implementation

### **2. `blockchain block` ✅ ENHANCED**


**New Multi-Chain Features**:
- **`--chain-id`**: Get specific block from designated chain
- **`--all-chains`**: Search for block across all available chains
- **Hash & Height Support**: Works with both block hashes and block numbers
- **Search Results**: Shows which chains contain the requested block

**Usage Examples**:
```bash


### **✅ User Experience Improvements**


**Enhanced Block Exploration**:
- **Chain-Specific Blocks**: Users can explore blocks from specific chains
- **Multi-Chain Block Search**: Find blocks across all chains simultaneously
- **Consistent Interface**: Same pattern across all block operations

**Improved Transaction Tracking**:
- **Chain-Specific Transactions**: Track transactions on designated chains
- **Cross-Chain Transaction Search**: Find transactions across all chains
- **Partial Success Handling**: See which chains contain the transaction

**Better Backward Compatibility**:
- **Default Behavior**: Existing commands work without modification
- **Smart Defaults**: Uses `ait-devnet` as default chain
- **Gradual Migration**: Users can adopt multi-chain features at their own pace



### **✅ Technical Benefits**


**Consistent Multi-Chain Pattern**:
- **Uniform Options**: All commands use `--chain-id` and `--all-chains`
- **Standardized Output**: Consistent JSON structure across commands
- **Error Handling**: Robust error handling for individual chain failures

**Enhanced Functionality**:
- **Parallel Queries**: Commands can query multiple chains efficiently
- **Chain Isolation**: Clear separation of data between chains
- **Scalable Design**: Easy to add new chains to the registry
