I was reading about CPFP (child pays for parents) recently and I didn't completely get the concept of it.
Can someone please give me a brief explanation of how it should be done and what are the wallets that currently support it?
Is my understanding of CPFP even correct? A user sends a transaction to another, which is not confirmed, that user can send another transaction that is "connected" to it with a high fee, that when a miner mines it, they are forced to mine the first, unconfirmed transaction?
