Confirmation

Definition ∞ A confirmation signifies the validation of a transaction on a blockchain. It indicates that a transaction has been processed and added to a block, and that this block has been accepted by the network consensus. Multiple confirmations increase the security and finality of a transaction.
Context ∞ Transaction confirmations are a critical metric discussed in relation to network efficiency and security, particularly during periods of high network congestion or when evaluating the reliability of a particular blockchain. News often highlights the average confirmation times or potential delays, which directly impact user experience and the perceived viability of a digital asset’s underlying infrastructure.
