It seems you don't fully understand what LN is. Simplified:
1. You post funding transaction on block chain (that locks up your money for the channel lifetime)
2. During channel lifetime (it can be a day, a month or even a year) you are free to exchange off-chain transactions with other LN users. Those TX are same BTC TX messages, however they never got posted to blockchain unless dispute occurs (in case of dispute, person who initiates premature channel closure gets punished) or channel naturally expires.
3. After channel closes - second - settlement transaction being posted to blockchain.
OK, this simplified explanation is very approachable. I have few questions though.
1. I'm opening my own LN channel. Funding it with 1
BTC and the fee for it is 100satoshi(simplified)
1a. Need to send bitcoins to new address on specially prepared software?
2. During channel operation, my laptop with LNnode works as an escrow between people and blockchain.
2a. I would have to make my 100satoshis back, so I set[?] fixed[?] fee for people to pay.
3. Channel closes and my "mini block" is sent in to chain. Do I pay another fee for this?
3a. Channel closes because of dispute, will I get my 100sats back? What if disputer has less than 100sats?
Who pays for "unused" bitcoins TX, that will have to be returned from my channel to me?
