The beneath is a direct excerpt of Marty’s Bent Difficulty #1106: “Jamming assaults on the Lightning Community and proposed options.” Join the publication right here.by way of BitMEX ResearchOur good good friend Gleb Naumenko dropped an unbelievable publish at the moment dissecting jamming assaults on the Lightning Community and a slew of proposed options from quite a few builders engaged on the second layer protocol. A Jamming 101 rationalization is described above, however to reiterate, it’s akin to a distributed denial of service assault generally waged towards explicit websites on the net. On the Lightning Community the same assault might be waged by a malicious actor who takes up channel capability by taking over sat actual property on a path by initiating a cost they by no means intend to finish. Freezing liquidity for different potential customers who might ship sats alongside the identical path.Up to now, this assault vector hasn’t been exploited to the most effective of my data. Nonetheless, it’s definitely attainable and it’s most likely most useful to acknowledge that and start to plan mitigation methods.That is precisely what this group of builders has achieved. Each resolution comes with tradeoffs, most of which pertain to privateness and costs. After studying via Gleb’s publish just a few occasions, it appears that evidently the most effective proposal pertains making a fame token with a staking mechanism, which might doubtless cut back privateness whereas including a charge to transactions. Even people who fail to get confirmed in a block. (If this sounds acquainted, that is as a result of that is at the moment attainable on Ethereum.)Is that this an unfixable downside? I doubt it. What I do know for certain is that I am completely satisfied there are people like Gleb, Antoine Riard, Joost Jagr, roasbeef, niftynei, t-bast, and lots of others who’re conducting crucial analysis to establish issues and suggest options.If something, posts like this are a reminder of how younger the BNP/LP stack is and the way a lot must be fortified and constructed out transferring ahead. Even when you’re not technical, I like to recommend studying this text. You will get a greater understanding of the topology of the Lightning Community.
