agreed LN in its blockstream concept is an alt.
the 'payments' performed within blockstreams LN are not bitcoin compatible.
the units of measure are different. so a signed LN 'payment' cannot be simply broadcast into bitcoin.
it requires rounding the altcoin to then be measured as a satoshi equivalent and then resigned. which only happens on closing the channel.
some say that its bitcoin due to using the same privkeys.
but then we come to the contraversial forks which use the same privkeys. so again an altcoin.
unless an LN concept uses the same units of measure any the LN 'signed payment' can at anytime be broadcast to bitcoin without needing to create a new tx just to close the payment session.. its an altcoin
segwit however is within bitcoin..
as for carlton.. ignore him he knows nothing about LN
Lol, I'm not going to check the details, just so i can speak to you, it's a waste of time after all
as proven
