A term native to the blockchain universe which describes the assurance that transactions on a network are genuinely final and cannot be modified in any way.
Finality is the term used to describe the irreversibility of successful blockchain transactions. On the one hand, the term is used in tandem with how long a crypto trader needs to wait until a transaction is confirmed and recorded on a block. In another way, finality refers to the strength and stability of a blockchain network which protects it from double spending or any other situation in which successful transactions can be reversed.
Finality is an important characteristic that smart crypto traders look out for before subscribing to any blockchain network. Moreover, different networks have different time required for finality.
