What Is An Unconfirmed Transaction?
An unconfirmed transaction has not been added to the Bitcoin blockchain yet. Transactions require confirmations, which are included in miners' block, to be deemed secure. Typically, after "6 confirmations," the transaction is considered highly secure because it's included in one block followed by five subsequent blocks. Delays in confirmations can be due to reasons like low miner fees attached to the transaction or network congestion. It's crucial to ensure appropriate fees for timely confirmations.
