A Lightning Network is a payment channel that aims to provide instant, feeless, tiny Bitcoin transactions. The transactions are feeless because you don’t use the Bitcoin blockchain where you have to pay miners. Instead you use a payment channel that is built on top of the Bitcoin blockchain. To open a payment channel users need to pay a fee for miners just like normal Bitcoin transactions and deposit the amount of Bitcoin you would like to transact. Once you’re on a payment channel you can can transact as much as you want without paying fee for miners. Since transactions are not taking place on the blockchain, you can be sure that your transactions are private. When you finish transacting, you close the channel for which you pay miners. Your final balance is entered back to the blockchain. You don’t have to worry about all these steps, your lightning network wallet will do it for you.
