Definition
A network confirmation is evidence that a blockchain transaction has been included in an accepted block, with later blocks increasing settlement confidence.
In market context
Platforms often wait for a specified number of confirmations before crediting a deposit because a newly included transaction may still be reorganized under network rules. Required counts vary by asset, amount, congestion, and risk policy, and a broadcast transaction can remain pending if its fee is inadequate. Confirmation indicates ledger inclusion; it does not prove that the sender used the correct network, address, asset, or memo.
Risk context
A confirmed transfer to an incompatible or unintended destination may be technically final and still unrecoverable.
