[TIP]
====
_Transactions_ move value *from* _transaction inputs_ *to* _transaction outputs_. An input is where the coin value is coming from, usually a previous transaction's output. A transaction output assigns a new owner to the value by associating it with a key. The destination key is called an _encumberance_. It imposes a requirement for a signature for the funds to be redeemed in future transactions. Outputs from one transaction can be used as inputs in a new transaction, thus creating a chain of ownership as the value is moved from address to address.

==== Creating the outputs
A transaction output is created in the form of a script that creates an encumberance on the value and can only be redeemed by the introduction of a solution to the script. In simpler terms, Alice's transaction output will contain a script that says something like "This output is payable to whoever can present a signature from the key corresponding to Bob's public address". Since only Bob has the wallet with the keys corresponding to that address, only Bob's wallet can present such a signature to redeem this output. Alice will therefore "encumber" the output value with a demand for a signature from Bob.

This transaction will also include a second output, because Alice's funds are in the form of a 0.10 BTC output, too much money for the 0.015 BTC cup of coffee. Alice will need 0.085 BTC in change. Alice's change payment is created _by Alice's wallet_ in the very same transaction as the payment to Bob. Essentially, Alice's wallet breaks her funds into two payments: one to Bob, and one back to herself. She can then use the change output in a subsequent transaction, thus spending it later.

That looks correct! Our new transaction "consumes" the unspent output from our confirmed transaction and then spends it in two outputs, one for 25 millibits to our new address and one for 24.5 millibits as change back to the original address. The difference of 0.5 millibits represents the transaction fee and will be credited to the miner who finds the block that includes our transaction.
As you may notice, the transaction contains an empty +scriptSig+ because we haven't signed it yet. Without a signature, this transaction is meaningless, we haven't yet proven that we *own* the address from which the unspent output is sourced. By signing, we remove the encumberance on the output and prove that we own this output and can spend it. We use the +signrawtransaction+ command to sign the transaction. It takes the raw transaction hex string as the parameter.

Now, the inputs used in the transaction contain a +scriptSig+, which is a digital signature proving ownership of address +1hvz...+ and removing the encumberance on the output so that it can be spent. The signature makes this transaction verifiable by any node in the bitcoin network.

Now it's time to submit the newly created transaction to the network. We do that with the command +sendrawtransaction+ which takes the raw hex string produced by +signrawtransaction+. This is the same string we just decoded above:
