A confirmation signifies a Bitcoin transaction has been included in a block on the blockchain, enhancing its security against reversal. In Bitcoin's system, transactions are grouped into blocks. Once a transaction finds its way into a successfully mined block, it gets its first confirmation. Each subsequent block mined provides an additional confirmation.
