The Vibe: Proof that your transaction is officially locked into the blockchain.
The Details: When you send crypto, miners or validators first put it in a pending pool. Each new block added to the chain that includes (or comes after) your transaction counts as one confirmation. More confirmations = harder to reverse (6 is considered very safe for Bitcoin, 1-3 is usually enough on Ethereum). Once confirmed, it’s permanent on the ledger.
Pro Tip: Check confirmation count on a block explorer using your TX hash—most wallets and exchanges won’t credit funds until a certain number of confirmations.
