What is Unconfirmed Transaction?

An unconfirmed transaction relates to the status of a transaction that is sent from one address to another on a blockchain protocol that has yet to be fully appended to the blockchain and finalized. Typically, in order for the recipient to receive the assets contained in a transaction, the transaction must go through several network confirmation stages. The number of network confirmations needed to finalize a transaction varies depending on the blockchain network the transaction originated from. In a blockchain context, an unconfirmed transaction is the opposite of a confirmed transaction.
