A bitcoin is a virtual cryptocurrency. It is often abbreviated as ''BTC'', ฿TC, or ฿. There is currently no official [[bitcoin symbol]] yet, however BTC is the most widely accepted short form.

A bitcoin address is a string made of up to 35 characters. It is case sensitive, but your bitcoin client is able to tell if the address you're providing is valid. A bitcoin address on the main network will always start with a 1.

(Optional) Choose preferred directory then click Next.
  
You can create as many bitcoin addresses as you want, your bitcoin client will handle all the adresses for you (inside the "address book") and show your global balance. Adresses are anonymous, and unless you give someone your address, nobody knows who is the owner of a given address. It is a common practice when receiving bitcoins to create a new bitcoin address each time. It also allows tracking who is sending you bitcoins, and for what.

  • You can be anonymous with adequate precautions.
  • You cannot send BTC to an invalid address. Typos are not a worry as the payment will refuse to send.

Proceed to the introduction

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 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 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.
