This program needs to synchronize the chains of blocks.



When you run the official client of a coin, part of the P2P network in that currency. This is the operating philosophy: when a transaction is created, this is recorded in the history of transactions. This record is public, and the same for everyone, and should download and remain saved on the computer from which opens the portfolio. Transactions must be confirmed. This process made it several nodes of the network (people who have open portfolio), and is to confirm the transaction, verify it. In this way, it is not possible (if someone got it), create false transactions (such as send money without removing it from your wallet). Theoretically, it would be possible if all nodes in the network are based on that false transaction, but it is something that could not happen. This is the reason that a transaction takes to be available.

A portfolio can have multiple addresses. All that you want you can create. The portfolios are saved in a file. DAT, also stored on the hard drive. This file saved as access to all of these addresses (therefore the backlog). Also stores transactions, but as something informative: the final accurate information is given by synchronization of the blocks of the wallet. It is therefore that this DAT file can be copied in other equipment, in order to create backup copies. Except that we believe and receive money in new directions, we can save a copy of the DAT and use it later, although we have received transactions, stored in the original file. To synchronize your purse in another computer, it will upgrade. If someone sends me money, when you send me, a few seconds, I will see that I received the payment, but it needs to be confirmed. When the first confirmation, in many currencies is possible already spend the money, even though a transaction is as confirmed when one achieves a minimum number of confirmations (and although it is confirmed completely, is confirmed by more people).
