Developers focusing on the Bitcoin layer 2 Lightning Network have grown to be less security-oriented and much more centered on producing income for his or her investors, argues an old Lightning Network developer.
Bitcoin core developer and security researcher Antoine Riard, made headlines recently after departing the Lightning ecosystem over concerns in regards to a new attack vector known as “replacement cycling,” which exploiters may potentially use to steal funds by targeting payment channels.
So how exactly does a lightning substitute cycling attack work?
There’s lots of discussion relating to this recently discovered vulnerability around the e-mail lists, however the actual mechanism is strict.
So here’s an highlighted primer…

At that time, Riard stated the brand new type of attacks puts Lighting inside a “perilous position” though other Bitcoin developers for example “Machine98” recommended it is really a difficult attack to drag off to begin with.
Riard told Cointelegraph that he’s now working in the Bitcoin first layer to deal with the problem and advised Lightning developers to follow along with suit:
“[They have to awaken, steer clear of the sleepwalking and visit the white board to create a strong and sustainable fix in hands along with other developers in the base-layer, preserving the lengthy-term decentralization and openness of Lightning.”
Riard also claimed that lots of Lightning-focused firms are compromising Lightning’s mission and security incentives with regard to pleasing vc’s:
“The sad fact being many of them will work for VC-funded entities, or commercial entities with similar low-time preference, in the lengthy-term hindrance of finish-users.”
Riard stated it’s a vintage illustration of the “tragedy from the commons” — where individuals and entities with use of an open resource act in their own individual interest and deplete it.
Decentralization seems to become a trade-off these VC-funded Lightning firms are prepared to make, that is a major concern to Riard.
“Centralized systems are wonderful within the proportions of efficiency, however they have the down-side of systemic single-point-of-failure minimizing price of user censorship, fundamental risks that certain should hedge against like a Bitcoiner.”
“I’m unsure it is really an interesting Lightning future,” Riard stated. Actually, it’s a thing that he wants no a part of, after departing in the Lightning ecosystem on March. 20:
“I don’t want to become connected with finding yourself in charge or accountable from the Lightning Network security, and also the ~5,300 BTC uncovered here. There’s little [I yet others can perform to prevent the haemorrhage, without compromising the main values of censorship-resistance and permissionless from the Lightning Network.”
Lightning is the greatest solution presently available, but it is not adequate enough.
Lightning has lots of fundamental flaws, where all of them result in the system in general a stalemate for bitcoin, lengthy term. An effort at explaining these, and that which you do rather.

The Lightning Network may be the second-layer solution built within the Bitcoin blockchain. It is made to enhance the scalability and efficiency of Bitcoin.
With the Lightning Network, users can open payment channels, conduct multiple transactions off-chain, and settle the ultimate result around the Bitcoin blockchain. The substitute cycling attack is really a new kind of attack that enables the attacker to steal funds from the funnel participant by exploiting inconsistencies between individual mempools.
Cointelegraph arrived at to Lightning Labs along with other firms within the Lighting ecosystem but didn’t get a response.
Don’t misunderstand me here: Lightning is excellent! Always still amazed when utilizing it.
The thing is it can’t scale enough. And Ark isn’t a competitor but much more of an add-on. Provides you with all the benefits of Cashu but without requiring trust.All we want is covenants. Ideally, CAT https://t.co/nhrmvqPYf0

However, regardless of the security concerns and potential move toward centralization, Riard described that Lightning hasn’t viewed as many attacks as numerous Ethereum layer 2s because Lightning users typically only store a tiny bit of funds within their wallets at any time.
As many as $194.a million in BTC is kept in the Lightning Network, according to DeFiLlama.
