    Description copied from class: Message
    
    Serializes this message to the provided stream. If you just want the raw bytes use bitcoinSerialize().

  - bitcoinSerialize
```
public byte[] bitcoinSerialize()
```
    Description copied from class: Message
    
    Returns a copy of the array returned by Message.unsafeBitcoinSerialize(), which is safe to mutate. If you need extra performance and can guarantee you won't write to the array, you can use the unsafe version.
    
    Overrides:
    
    bitcoinSerialize in class Message
    
    Returns:
    
    a freshly allocated serialized byte array
