Nano Seagull ⋰·⋰: Yet another attack vector discovered for the #LightningNetwork. The more moving parts your system has, the more probable is that it will break down.

Nikita Zhavoronkov: That’s because Lightning on top of 1 MB blocks is a fundamentally flawed centralized concept. If some of the “big hubs” start to misbehave, honest users simply won’t have enough block space and time to fix that.

Seth Simmons: New attack (and paper on it!) published today against the #LightningNetwork Certainly thankful that this type of research is published. This seems pretty dangerous for the core function of LN today, so I’ll be curious to see what the response is.

if (BTC.IsSoV) {Titanic.IsStoreOfPassengers=true};: @mikew3456 @RookieXBT It's not a waste of time to warn people away from the "not-a-Ponzi-but-as-close-to-one-as-makes-no-difference" ur-Shitcoin #Bitcoin $BTC. The second layers do not share Bitcoin's security, but have their own security (and scaling) problems. https://arxiv.org/abs/2006.08513

if (BTC.IsSoV) {Titanic.IsStoreOfPassengers=true};: @jp_koning @LNJunkies A recent "Flood and Loot" attack vector was revealed, which is made easier whenever Bitcoin mainchain approaches capacity. I'm no cryptographer, so I'm open to correction, but it appears to me that it has no mitigation even possible at protocol level. https://arxiv.org/abs/2006.08513 https://t.co/Tv7dqvH4cf
