If you are sent bitcoins when your wallet client program is not running and you later launch it, it will download blocks and catch up with any transactions it did not already know about, and the bitcoins will eventually appear as if they were just received in real time. This situation isn't to suggest, however, that the markets aren't vulnerable to price manipulation; it still doesn't take significant amounts of money to move the market price up or down, and thus Bitcoin remains a volatile asset thus far. This requires miners to perform these calculations before their blocks are accepted by the network and before they are rewarded. Transparent and neutral - All information concerning the Bitcoin money supply itself is readily available on the block chain for anybody to verify and use in real-time. And the reason it's going to bind it is we're using a digital signature scheme, and so anybody who possesses Alice's public key, which, again, is made public, can validate that only Alice could have created this block because only Alice, in theory, can come up with the signature that corresponds to her public key because she's the only person who, in theory, should possess the private signing key corresponding to her public key, all right?
Transparent and neutral - All information concerning the Bitcoin money supply itself is readily available on the block chain for anybody to verify and use in real-time.

Although unlike Bitcoin, their total energy consumption is not transparent and cannot be as easily measured. When using bitcoind, the client gives you the txid as the response for a successful send. Any rich organization could choose to invest in mining hardware to control half of the computing power of the network and become able to block or reverse recent transactions. Transaction records. Well, if you think about it, at this point, we've just used cryptographic hashing and digital signing to validate that Alice at some point possessed the requisite bitcoins in the system, and that she not only publically announced her intention to transfer some of the bitcoins to Bob, but she digitally signed that public pronouncement, if you will, as a result of which, her public verification key, which is her identity in the bitcoin system, is now bound to that transaction. Now, remember, that these values also correspond to private values, so each person who's got a public key will have a corresponding private key, associated with that public key, and in this case, we'll call the private key, or the secret key, which is, in fact, a signing key in this context, SK of Alice, and we'll say that Bob's signing key is SK of Bob. Transparent and neutral - All information concerning the Bitcoin money supply itself is readily available on the block chain for anybody to verify and use in real-time.
