wrong
1. LN uses HTLC's for payment not bitcoin CLTV's
2. the denomination(unit of account) of LN is Msat which is something bitcoin does not accept
3. LN can function with just swapping(hot potato) msats using lite wallets that do not api/RPC a blockchain
4. if you were to API/RPC a blockchain your node can use the chainhash of litecoin, vertcoin or others. not just btc
5. refer to point 4 above
6. LN is a single network where multiple nodes can communicate where ach node can designate a different chainhash, to allow swapping on the same network
1. it still doesn't make what i said wrong!
2. same as 1 although it is a very questionable decision to create msat in my opinion.
3-4-5-6. it sounds like you are saying if there is a multi-coin wallet like Jaxx for example then since that wallet supports more coins then there is no difference between those coins! when you have bitcoin in your LN channel you have bitcoin in your LN channel not litecoin or vertcoin or... if you want those you have to exchange them with someone else who wants bitcoin in return.
LN was built and then bitcoin had to change and get a new tx format to be LN compatible. also litecoin added this tx format before bitcoin did, thus technically bitcoin copied litecoin
the code was written for bitcoin then LTC and a dozen other small altcoins pulled the code in their client from bitcoin and activated it because they were small and had no drama like bitcoin had.
