Due to the decentralized nature of the Blockchain, Kreditcoins can be sent across the world in seconds. For a Kredit transaction to be deemed valid to must have one or more inputs. Inputs are the Record on the Blockchain that show that the Kreditcoins in your Wallet were sent to you and that you are therefore the owner of the Kreditcoins in question. Each and every input must be an unspent output of a previous transaction. This ensures the Kreditcoins are unspent and that Kreditcoins cannot be spent twice.
Is creating a transaction an extensive process?
Technically yes, it's a very technical process, however from a user point of view it's as simple as entering the receiving address, amount and pressing send, the software completes all necessary functions automatically.
The transaction must also have the digital signature of every input used in the transaction. More often than not the Kreditcoins transacted will come from more than one input source. The users' addresses are included in the transaction data to prove the source of every Kreditcoin used.
Is there a limit to how many different inputs there are to my Wallet balance?
No, there is no limit on how many inputs are used neither on the amount of your Wallet balance. You could in theory store all the Kreditcoins in existence in a single Wallet.
An Additional Output: Your Change Address
Just like a cash transaction, the sum of inputs can exceed the intended sum of payments. In this event, an additional output is used, returning the difference back to the payer, just like receiving change at a point of sale. This process is completed automatically by the network and requires no input from you, save authorizing the initial transaction.
What if my change amount isn't returned?
This never happens as the intended transaction amount is recorded in the initial transaction. The Kredit Network is designed to only give the specified amount to the recipient, which is why it is important that you make sure that the amount you're sending is correct as the transaction cannot be reversed.
