Nice paper on LN routing. Findings: 1. Centralization: - 5 nodes participate in 60% of the routes - 10 nodes -> 80% of the routes - 30 nodes -> 95% 2. Hijacking potential: - by creating 5 new channels, an attacker can hijack 65% of the routes - 30 channels -> 80% of the routes

Our paper on Hijacking Routes in Payment Channel Networks: tl;dr: in today's #LightningNetwork it's not too hard to grab a large fraction of the payments (and deny service). With @SaarTochner & @schmiste78 cc @ct_univie @CseHuji @HUJICyberLaw

I have just read a new study about the #BTC Lightning Network. Nearly 80% of all routes pass through only 10 nodes. It is easy and cheap to commit a DOS attack. I believe in real decentralization so I am with #Cardano. #blockchain $ada $btc $eth $xrp

Another new problem with the Lightning Network. BTC is simply a failed project, ruined by devs who treated it as a science project. There's no reason to replace proven, reliable tech (on-chain tx's) with speculative, insecure tech. Big-block Bitcoin is the answer.

We just published a Medium post explaining this paper. This is the second paper on #LightningNetwork to come from our lab recently, and more are in the pipeline! ⚡️⚡️⚡️

Sometimes I feel like certain cryptocurrency researchers missed the memo where the game theoretic properties of a cryptosystem are not supposed to be exciting for attackers to explore

Excellent work from @Avivz78 's group on a simple attack on the Lightning Network. This will not be the last attack on LN routing.

REMINDER: next time Bitcoiners shill the awesomeness of #LightningNetwork, politely point them to this academic paper on #Lightning. then don’t forget to use this hash tag: #LightningAttackVector™️ 🤷🏻‍♂️⚡️
