[bitcoin-dev] Off-chain transactions and miner fees

Nodes in the Lightning network earn fees that wouldn't be there if it weren't for the Lightning network. The base Bitcoin layer can't handle the transaction throughout that Lightning can, so the Lightning fees were never available to Bitcoin miners in the first place.

What Lightning does is raise the value of a transaction on the block chain. Imagine you're a Lightning node, and in order to collect your fees, that you've earned over the past month, you have to settle on the blockchain. If you've earned, say, 0.5 BTC in fees, you can attach a huge 0.005 BTC fee to the Bitcoin settlement transaction. The miners earn a larger fee, and you make sure your transaction gets into the blockchain quickly, and you can afford to pay this fee because you've made much more on the Lightning transactions you've routed.
