Zero Confirmation Transaction
By CoinGecko | Updated on Mar 03, 2020
A cryptographic transaction via the blockchain is only considered "confirmed" when it is included in a block, which is after miners have verified, hashed and recorded the transaction (aka mined the transaction). Once a transaction has been mined, it becomes increasingly difficult to maliciously reverse the by way of hacking as more blocks gets mined subsequently.
A zero-conformation-trasaction carries the risk of it being overwitten and invalid until it has been mined, and should never be considered as final when performing a transactional trade.
