Zero Confirmation Transactions
Zero confirmation transactions are transactions that have been broadcast to the network but have not yet been included in a block. These are considered risky because they have not been verified by the consensus mechanism and could still be replaced or double-spent.
Merchants or exchanges that accept these transactions are taking on the risk that the transaction might never be confirmed or might be superseded by another. Despite the risk, they are often used for small, low-value payments where speed is prioritized over absolute security.
They demonstrate the trade-off between transaction speed and settlement certainty in digital asset markets. Users must be aware that until a transaction is mined, it is not finalized.
