Can each Bitcoin and Satoshi be uniquely identified? I'm pretty sure I've read somewhere that BitCoins have an "address", so they can be uniquely identified.

What I want to know is:


Does each Satoshi have it's own unique identity?
How is the identity of a Satoshi formatted? (providing 1 is true)
Bitcoins and satoshis do not have unique identities.

However, Bitcoin balances are stored in uniquely identifiable "transaction outputs" that can only be spent by the owner of the recipient address.


  Example:
   Alice sends Bob 1 BTC, Bob uses it to send another payment.
  
  When Alice sends Bob a payment of 1 BTC, she signs a transaction that deducts 1 BTC from her funds and creates a new transaction output that is worth 1 BTC and can only be spent by Bob, the owner of the recipient address.
  
  Bob now wants to send 0.4 BTC to Charles. The transaction output from Alice's transaction is now used to fund this new transaction. The transaction creates two new outputs: One with 0.4 BTC that is associated with Charles' address, and one with 0.6 BTC associated with Bob's address (it is the change). The first transaction output (from Alice's transaction) is consumed by the transaction.


Unspent Transaction Outputs are identified by the (unique) hash of the transaction they were created in, and their position in the list of outputs.
