Understanding Zero Confirmation Transactions
Zero confirmation transactions are transactions that have not yet been included in a block but are still considered valid transfers of funds by the network.
When transactions are made, they are grouped together in blocks, which then form a blockchain.
After a transaction is sent, it goes through three possible states: unconfirmed pending confirmation, confirmed, or rejected.
If the transaction fee is too low or if there is a high volume of transactions waiting to be processed, the confirmation of a transaction may be delayed. These unconfirmed transactions are also known as zero confirmation transactions.
