> i.e. the public keys you pay to. Or the public keys you pay from. You can break a txn into multiple components, each of which is formed as a function of a deterministic wallet. By having multiple change addresses you'd have more message space. > Every node receives every message. You could even send it with a very low mining fee, and theoretically the message would disappear. But it would require gaming of the system, because many nodes wouldn't pass-on txns that don't have a minimum txn fee. This functionality is one of the key reasons that blocksize space needs to be controlled on a block-chain.
