One thing that you'll see in this block explorer view of your transaction that wasn't obvious in the command line lookup is a fee (.00000226 BTC). It costs money to use the Bitcoin network; the money goes to miners who creates the blocks. However, the amount of the fee wasn't obvious from a casual perusual of the rawtransaction because it's just the different between the input and the output. This will have _notable_ implications when you begin writing raw transactions; not understanding it can lead to the worse problems in Bitcoin programming: _loss of funds!_
|
A block explorer doesn't generally provide any more information than a command line look at a raw transaction; it just does a good job of highlighting the important information and putting together the puzzle pieces, so that you know what you're seeing.

Faucets will give you money on the testnet. They come in as rawtransactions, which can be examined with 'getrawtransaction' or a block explorer. Once you've receive a transaction, you can see it in your balance and your wallet.

## Part Three: Sending a Raw Transaction
|
||||||
|
|
||||||
|
We're now ready to create Bitcoin transactions. For this purpose, we'll need a few new addresses. We've created a new one with the 'getnewaddress' command (msoix3SHNr6eRDUJsRSqQwZRhxZnLXhNef), which will appear as a separate address in our wallet. We'll also be sending some coins back to TP's testnet faucet (n2eMqTT929pb1RDNuqEnxdaLau1rxy3efi).
|
||||||
|
|
||||||
|
### Optional: Send Coins the Easy Way
|
||||||
|
|
||||||
|
It's actually _really_ simple to send coins via the command line. You just type 'bitcoin-cli sendtoaddress [address] [amount]'. So, to send a little coinage to my other address just requires:
|
||||||
|
```
|
||||||
|
$ bitcoin-cli sendtoaddress msoix3SHNr6eRDUJsRSqQwZRhxZnLXhNef 0.1
|
||||||
|
6ad295c280798e9746dcdf7e5a60dfb6219d93bf31aab9b540ce892537c41e0c
|
||||||
|
```
|
||||||
|
Make sure the address you write is in where you want the money to go. Make _double_ sure. If you make mistakes in Bitcoin, there's no going back.
|
||||||
|
|
||||||
|
You'll receive a txid when you issue this command.
|
||||||
|
|
||||||
|
> **WARNING:** The bitcoin-cli command generates JSON RPC commands to talk to the bitcoind. They can be really picky. This is an example: if you list the bitcoin amount without the leading zero (i.e. ".1" instead of "0.1"), then bitcoin-cli will fail with a mysterious message.
|
||||||
|
|
||||||
|
You'll be able to see the transaction in your list immediately, but it'll take a little longer for your balances to settle, as usual. Here, note that we see the transactions for both sending the money _and_ receiving it, since it's all local. If you're sending to someone else, you'll just see the sending.
|
||||||
|
```
|
||||||
|

Mind you, this isn't necessarily that interesting if you're planning to write your own rawtransactions. But, it's a great test so that you can successfully see a transaction leave your machine, taking some of your money with it.
