There are no direct implications on the security of Bitcoin itself, but when you use Lightning, it will be a different trust model than the one we're currently accustomed to. The person you open the payment channel with can choose to close it at any time, including a time that may be inconvenient to you. Whichever balance is recorded at that time is the one that will be saved to the blockchain, which again, may not be what you wanted. So there are possible attack vectors where unscrupulous actors can walk away with your money if you aren't paying attention. Generally, though, as long as you only deal with reputable companies and people you know and trust, this shouldn't be an issue. Plus, because Lightning is generally aimed at improving microtransactions, there hopefully won't be any large sums at risk. If it's a large sum of money, just put it straight on the blockchain as you currently do now.
So you mean centralized using hubs and that's what we should had done from the start instead of all this Pow Bull crap
that wastes CPU power and put the miners into a CPU war when mining but now they made the hubs like bankers
loaning coins out, gone from bad to worse really.
This is the main reason BTC and the clones will not scale and it was obvious from the start and now we are
being scammed on mining fees. Central coordinators does not mean you have to give up you virginity you know
