Transaction IDs are not authoritative until a transaction has been confirmed. Absence of a transaction hash in the blockchain does not mean the transaction was not processed. This is known as((("transaction malleability"))) "transaction malleability," because transaction hashes can be modified prior to confirmation in a block. After confirmation, the txid is immutable and authoritative.

The transaction form shown with the command +gettransaction+ is the simplified form. To retrieve the full transaction code and decode it we will use two commands: +getrawtransaction+ and +decoderawtransaction+. First, +getrawtransaction+ takes the _transaction hash (txid)_ as a parameter and returns the full transaction as a "raw" hex string, exactly as it exists on the bitcoin network:

To decode this hex string, we can use the +decoderawtransaction+ command. Copy and paste the hex as the first parameter of +decoderawtransaction+ to get the full contents interpreted as a JSON data structure (for formatting reasons the hex string is shortened in the following example):
