There is no added risk of double spend in lightning. The risk in lightning is that your counterparty can close the channel on an old state that benefits them. If you, or your watchtower (not yet implemented) is not there to punish fast enough, they can run away with your bitcoin.
- WJW 9y agoWhat happens if they DDOS you (or your watchtower) at the right moment? Most peoples' bandwidth is shit enough that forcing them offline is fairly straightforward.
- __blockcipher__ 9y agoYou get fucked over. That, along with hot wallets, is why lightning is a horrific security nightmare. It's not built to withstand adversarial attacks the way bitcoin itself was. To be blunt, they took an elegant vision by Satoshi and shit all over it
- Klathmon 9y agoLocktimes are about 3 days, they would have to ddos you for the whole time in order to steal anything. If at any point during those 3 days you are able to broadcast your transaction in any way, you get all the money in the channel from both participants.
