Our good good friend Gleb Naumenko dropped an incredible post at the moment dissecting jamming assaults on the Lightning Community and a slew of proposed options from a variety of 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 internet. On the Lightning Community the same assault will be waged by a malicious actor who takes up channel capability by taking on sat actual property on a path by initiating a cost they by no means intend to finish. Freezing liquidity for different potential customers who may ship sats alongside the identical path.

Up to now, this assault vector hasn’t been exploited to the perfect of my information. Nonetheless, it’s definitely potential and it’s in all probability most helpful to acknowledge that and start to plot mitigation strategies.

That is precisely what this group of builders has executed. Each answer comes with tradeoffs, most of which pertain to privateness and charges. After studying by means of Gleb’s publish a number of instances, evidently the perfect proposal pertains making a repute token with a staking mechanism, which might possible scale back privateness whereas including a payment to transactions. Even those who fail to get confirmed in a block. (If this sounds acquainted, that is as a result of that is presently potential on Ethereum.)

Is that this an unfixable downside? I doubt it. What I do know for certain is that I am joyful there are people like Gleb, Antoine Riard, Joost Jagr, roasbeef, niftynei, t-bast, and plenty of others who’re conducting vital 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 for those who’re not technical, I like to recommend studying this text. You may get a greater understanding of the topology of the Lightning Community.
