Broadcast an old transaction in LN, and the other LN user can confiscate your entire amount in the channel.
Don't do that, that just means you're trying to break the system, and the other LN can confiscate your entire amount as deterrent from someone trying to cheat the system.
Know what you're doing, in other words. It has happened to a few other users but it's all their fault really.
And if LN had been designed
without revocations in place, the detractors and trolls would have a really easy job, because then all you would need to do is always spend from an outdated commitment and easily defraud people. The current implementation of Lightning would not be possible without revocations. So it only makes the trolls look even more ridiculous and ill-informed when they claim that the very part that makes it secure is somehow a bad thing for users.
We'll also have to see what happens with
Eltoo, since there may be an alternative way to handle maintaining channel states. I look forward to the trolls' feeble attempts to undermine that one as well.
Can Strike be used to buy bitcoin? Sure, create an invoice from your existing wallet and pay it. After completion, youll have less fiat in Strike and more bitcoin in your wallet.
Can Strike be used to sell bitcoin? Sure, create a request in Strike and send to it from your wallet. After completion, youll have more fiat in Strike and less bitcoin in your wallet.
i really don't understand how it works under the hood. where is the BTC to fulfill invoices being sourced from? it seems like there must be a centralized market making mechanism to be able to instantly fulfill the requests.
I can see how that would be a tricky one from a business perspective. On the one hand, they want to assure people it's a legitimate business model, but on the other hand, they probably can't give away the finer details until they're a little more established, in order to avoid another company playing copycat and ripping off their business model. They'll naturally want to make the most of first-mover advantage.
