No. Payment channels are not centralized. Here you go again, trying to spread FUD in regards to something which you do not understand. Seems like you're part of the DunningKruger effect as described by the troll above me.
in another topic lauda pretended LN doesnt use hubs..
now he is saying there are no central intermediataries..
LN uses nodes in the same way that the p2p Bitcoin network uses nodes. None of them are special. Anyone can run a node. Each node connects to multiple other nodes. None of them are centralised.
im guessing he will rebut talking about the spokes.. (users sending transactions) but will pretend the hub(intermediary) doesnt exist. and yet its this intermediary that
actually works as a "mempool" and does the closing of the channel and settling the final large transaction..
The hubs are the nodes and the spokes are the connections between the nodes.
i wonder what would happen if someone DDoSed the hub(intermediary) before it had a chance to settle... by by transactions
Instead of wondering about it you could research it. If any node goes offline before its channels are closed, the channel will be closed when the timelocked transaction becomes valid, after a suitable delay.
Did you recently buy this account from the original Franky? I seem to remember talking with Franky a few years ago and he seemed smarter then. It could just be that he was agreeing with me then. That can make me think people are smart when in fact they're just repeating something they've read.
