Zero Confirmation Transactions: Faster Bitcoin Payments

Zero Confirmation Transaction is an alternative wording for an unconfirmed transaction.

What are Zero Confirmation Transactions?

Every transaction must be included in a block in order to be validated by the network as a valid funds transfer. Transactions carried out at the same time are collected into blocks that together form the blockchain.

Once a transaction is sent, it goes into one of three states: unconfirmed, pending confirmation, confirmed or rejected.

Confirmation may be delayed if the fee for the transaction is not high enough for miners confirming transactions, or if there is a large volume of transactions waiting to be processed. Transactions with zero confirmation are also known as unconfirmed transactions.
