Lightning network?

[Murloc]

Helly guys!
Can anyone pls explain me how Lightning network gona work? Some reputable people say that it may be the only way to reduce fees but there is too much FUD from BCH devs and followers about it in the internet (that can not be trusted) so it is pretty hard to find a decent and clear source of information. So what I want to know is that how it gona wort? Is it dangerous for something and why? And of you can just express your opinion about it.

I don't think there's really a simple way of explaining it because the underlying mechanisms are rather complicated, but at the most basic level, it allows the use of smart contracts for "instant" confirmations. I can sign a transaction and hand it to you off chain, at which point it's already final because I can't take it back. That effectively means you're already holding the coins even if the transaction hasn't actually confirmed yet. That's my understanding of it, at least.

I don't think there are clear downsides, but it makes use of payment channels to facilitate transactions and it seems to be unclear how much that would cost.

We've seen what BCH and people behind it are trying to do with bitcoin, centralization. I wouldn't give them much attention regardless of what they say, just stay away from /r/btc.
