<div style="background:#dddddd;border:solid gray 1px;width:70%;margin:auto;">
Current releases of the bitcoin client have a different user interface than the versions used in this article.

This article could use an update. See the discussion for this article for more.
</div>

This page is a detailed tutorial to help new users understand and using bitcoin. After you read this page, you'll know the basics of what bitcoin is and how it is structured, how to get and install the bitcoin client, where to get coins, and how to use the client to send and receive transactions.

If you want to ignore all the details of how the system works, and just want to start using it, see the [[Getting started]] page instead.

=What is Bitcoin=

: Main Article: [[How bitcoin works]]

Bitcoin is a distributed [[digital currency]] based on strong cryptographic principles. Each coin is assigned to the owner's public key, and is transferrable via cryptographically signed messages.

=Getting started=

In this section, you'll learn where to get the client, how to install it on different operating systems, and download the [[block chain]].

==Download and install the client==

First, download the bitcoin client from http://bitcoin.org/. Choose the appropriate link depending on your operating system, and install in the usual manner. For Windows, easiest is probably the executable installer. For Linux, note that the tar.gz contains the binary build, in addition to the source, so if you run a recent distribution, you should be able to just run the binary without compiling yourself.

==Starting the client and connecting to the network==

[[File:First time run fin.png|400px|thumb|right|Bitcoin is initializing by establishing a connection to other clients and downloading the blocks.]]
Bitcoin comes with a GUI client called "bitcoin", and a CLI (text-mode) client called "bitcoind". It is probably more user-friendly to start with the GUI, so launch the bitcoin client.

When you start for the first time, your bitcoin wallet will be created automatically, and the client will attempt to establish connections to other nodes on the network and start downloading the bitcoin [[block chain]]. You must get all of the blocks in the chain before sending/receiving transactions. [http://blockexplorer.com/q/getblockcount Click here] to see the current number of blocks in the chain. This download may take as long as several hours.

==Client features==

Your starting bitcoin address (you can have as many as you want - we'll talk about [[#Bitcoin addresses|addresses]] later) shows in a text box at the top. Right below it is your total bitcoin balance, which, of course, to start with will be zero. There is a list box below it showing all your transactions, which can be variously filtered with tabs, which again will be empty to start with.

The status bar at the bottom will display some important information. If you have [[#Generating bitcoins|bitcoin generation (block hashing)]] turned on, on the left the client will display your hash rate. To the right of that, you will see the number of bitcoin nodes your client is connected to, then, the number of blocks your client has in its chain, and finally, the number of transactions you have in your wallet.

=Using bitcoin=

In this section you will learn about bitcoin addresses, sending and receiving transactions, the block chain and transaction confirmations, where to get your first bitcoins (faucet), generation. Tips on keeping wallet safe.

==Getting your first bitcoins==

There are few things more exciting than getting your first bitcoins! So once you have all the blocks downloaded, head on over to the [https://freebitcoins.appspot.com/ bitcoin faucet], fill out the form and put in your bitcoin address, and receive some free bitcoin! (You can do this before finishing the block chain download, but you won't see the coins in your wallet until you finish downloading the blocks... which would put a damper on the whole excitement bit.)

See [http://en.bitcoin.it/wiki/Trade#Samples_and_Marketing_Offers Samples and Marketing Offers] for other free bitcoins and marketing offers.

Once you submit the form successfully, you should see a new transaction in your client within seconds. But it will be grayed out, and have 0/unconfirmed status:
[[File:First btc recv.png|frame|none]]

Once your transaction makes it into the block chain, the confirmation count will grow in step with the number of blocks in the chain. By default, the client stops showing "unconfirmed" after the transaction is 6 blocks deep in the chain:
[[File:Six confirms bitcoin client.png|frame|none]]

==Transaction confirmations==

write about [[Blocks|blocks]] and [[Confirmation|confirmations]] here.

thanks to the [[Block chain|block chain]], you don't need to be online for receiving BTC...

==Bitcoin addresses==

You can create as many new addresses as you like. Using a different address each time helps to preserve your [[anonymity]].

You cannot send BTC to an invalid address. Client will refuse to send payment to a misspecified address. (Though with care you can craft a valid but nonexistent address.)

Physical Bitcoins are bearer tokens that have an embedded redeemable digital bitcoin value if torn open.

Help:Installing Bitcoin Core

2012-01-19T16:19:09Z

BTCfan:

An account can effortlessly be created using an [[eWallet]] service. eWallet services provide an online wallet to hold your bitcoins.

This guide covers installing Bitcoin without needing a third party wallet service.

== For Windows computers ==

=== Installation ===
[http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.5.1/bitcoin-0.5.1-win32-setup.exe/download Download Bitcoin] and install it.

[[File:Install fin.png|frame|none|Complete installation wizard]]

=== Initialization ===

The first time you run Bitcoin, it needs to download all the blocks to setup. You already have your bitcoin address at this point, but you won't see any transactions before the initialisation is complete (it can take from half to a few hours).

[[File:First time run fin.png|frame|none|Bitcoin is initialising by establishing a connection to other clients and downloading the blocks.]]

[[File:Bitcoin all blocks fin.png|frame|none|Completed download of block-chain.]]

Your address (you can have as many as you want) is at the top. Below is your balance which will be zero. The list below shows your transactions.

== For Mac computers ==
[http://downloads.sourceforge.net/project/bitcoin/Bitcoin/bitcoin-0.5.1/bitcoin-0.5.1-macosx.dmg Download Bitcoin] and expand the disk image.

[[File:BcOSX.png|frame|none|Contents of the Bitcoin disk image after expansion]]

Drag the Bitcoin icon to the desired install location, and double-click the icon to run the application. The Bitcoin window will open and connections will start up in minutes. The blocks will begin downloading. Your address and balance are at the top of the window. Click "Copy to clipboard" to copy your address. Transactions are displayed in the main window.

[[File:BcOSXrunning.png|frame|none|Main window]]
[[File:BcOSXPreferences.png|frame|none|Preferences window on OS X]]

== Getting my first coins ==

The German Bitcoin market place [[bitcoin.de]] offers 0.01 BTC for every new [https://www.bitcoin.de/en/registrieren registered] user. The [[Bitcoin Faucet]] [https://freebitcoins.appspot.com/ website] currently hands out 0.001 BTC to new bitcoin users. Fill in the form with your bitcoin address. [http://www.wesmeredith.com/bitbybit/ Bit by Bit] is another website which provides.001 BTC for free and can be used daily. It also offers weekly lottery drawings for beginners. When you wish to add more, view [[Buying bitcoins]].

[[File:Get some btc.png|frame|none|Getting free coins from the Faucet]]

A new entry should appear in Bitcoin. The network hasn't yet confirmed it, but you know it's being processed. After about one hour it should get 6 confirmations. You are able to spend the coins when there is only one confirmation.

The confirmation counter (like the block counter) will increase by one roughly every 10 minutes. Six confirmations are considered as 100% sure a transfer has been processed.

[[File:First btc recv.png|frame|none]]

[[File:Six confirms bitcoin client.png|frame|none]]

* The [[Trade]] article shows hundreds of merchants who accept bitcoins.

== Buying coins on Bitcoinmarket24.com via SEPA or wire transfer (EUR only) ==
Go to [https://bitcoinmarket24.com/ Bitcoinmarket24]

# If you want to use instant payment, enter the desired amount fo Bitcoins as well as your bitcoin address and klick on next (optionally enter your e-mailaddress)
# Enter your payment details on the following side (TÜV certified)
# You receive your Bitcoins within less than one minute (note: you still need to wait for the confirmations of the network)

# Alternatively click on "Switch to traditional SEPA bitcoin purchase"
# Enter amount of Bitcoins, bitcoin-address, name of bank account holder and your e-mailaddress
# Click on "Next"
# Check your data and click on "Next"
# You receive all data that you need to do the transfer
# After 1 day for German transfer and 1-3 days for European SEPA transfer you will be credited your Bitcoins

== Points to remember ==

* You don't need to be online to receive BTC.
* You can create as many new addresses as you like. Using a different address each time helps keep you [[Anonymity|anonymous]].
* You can be [[Anonymity|anonymous]] with adequate precautions.
* You cannot send BTC to an invalid address. Typos are not a worry as the payment will refuse to send.
* The [[Wallet|wallet]] file holds the keys that allow spending and thus the computer should be [[Securing_your_wallet|protected]] from the risk of loss and theft.
* Leaving Bitcoin open improves connectivity for the network and ensures that you don't fall behind on the block chain. Also see [[FAQ#Do_I_need_to_configure_my_firewall_to_run_bitcoin?|the FAQ about port forwarding]]

== Technical ==
=== Block chain ===
The [[block chain]] is a never-ending story of every transaction throughout the network from day 1 (genesis). The first time you run Bitcoin, it is downloaded and verified on your computer. Every new transaction is added to the end of this chain and verified by the network to be valid.

=== Addresses ===
Whenever you send a coin, you are actually sending a cryptographically signed message, associating your coin with the recipient's address. This effectively transfers ownership to to the recipient. Once they own the coin, they are free to transfer it to another person.

A wallet is a collection of addresses. You can create as many new addresses as you wish; having more addresses makes you more anonymous, because then people cannot see how much BTC you received. Your wallet contains the secret keys used for spending that money, and must be [[Securing your wallet|backed-up regularly]]. If you lose the wallet then you no longer possess the money.

=== Generating ===
New coins are mined through generating hashes. These generators are rewarded with a small fee for the computationally intensive task of incorporating your transactions into the block-chain. This fee halves each time 210000 blocks are added to the block chain, or approximately every 4 years. The fee will keep halving until it effectively reaches zero, at which point 21 million coins will be in circulation.
