Later, when we get to the models for the block and the vote, we'll see that both include a signature (from the node which created it). You may wonder why transactions don't have signatures... The answer is that they do! They're just hidden inside the ``fulfillment`` string of each input. A creation transaction is signed by whoever created it. A transfer transaction is signed by whoever currently controls or owns it.
What gets signed? For each input in the transaction, the "fullfillment message" that gets signed includes the JSON serialized body of the transaction, minus any fulfillment strings, and with "n:" prepended where n is the index of the input being signed. The computed signature goes into creating the ``fulfillment`` string of the input.
