This is a fantastic web site from Antoine Riard and Gleb Naumenko that breaks down the channel jamming downside on the Lightning Community. I extremely suggest you freaks test it out if you wish to get a greater understanding of one of many larger assault vectors of the Lightning Community and the way builders are desirous about it. Briefly, a channel jamming assault is a denial-of-service assault that permits a nefarious actor or actors to stop routing nodes from forwarding funds inside a channel. Growing the quantity of failed funds and decreasing the reliability of the lightning community general within the course of. Not preferrred, however completely attainable in the intervening time.

Whereas many see unimaginable promise within the Lightning Community, myself included, it is usually necessary that we be upfront with its shortcomings in order that we will try to repair them as we construct out the community. Attempting to fake they do not exist will not be useful in the long term. This is the reason we’re extraordinarily lucky that good people like Riard and Naumenko, amongst many others, are on the market doing essential analysis, brainstorming and testing to find methods these issues might be solved.

It does not look like there’s consensus on whether or not or not any of those options are preferrred or sensible at scale. Nevertheless, this web site is a superb leaping off level to stoke dialog amongst builders and customers alike who want to remedy this downside. Extra consciousness results in extra minds desirous about these issues and that is a great factor in the long term.
Kudos to Riard, Naumenko and each different developer working to unravel these issues. The work that they’re doing is essential and will show to make humanity extra free and the world a greater place in our lifetime.
