Builders engaged on the Bitcoin layer 2 Lightning Community have develop into much less security-oriented and extra targeted on producing money stream for his or her buyers, argues a former Lightning Community developer.
Bitcoin core developer and security researcher Antoine Riard, made headlines final month after leaving the Lightning ecosystem over considerations a couple of new assault vector referred to as “alternative biking,” which exploiters might probably use to steal funds by focusing on fee channels.

On the time, Riard stated the brand new class of assaults places Lighting in a “perilous place” although different Bitcoin builders equivalent to “Machine98” suggested it’s a tough assault to drag off within the first place.
Riard advised Cointelegraph that he’s now working on the Bitcoin base layer to deal with the problem and urged Lightning builders to comply with swimsuit:
“[They need to] get up, cease the sleepwalking and go to the whiteboard to design a sturdy and sustainable fix in hand with different builders on the base-layer, preserving the long-term decentralization and openness of Lightning.”
Riard additionally claimed that many Lightning-focused corporations are compromising Lightning’s mission and security incentives for the sake of pleasing enterprise capitalists:
“The unhappy truth being most of them are working for VC-funded entities, or business entities with the identical low-time choice, on the long-term detriment of end-users.”
Riard stated it’s a traditional instance of the “tragedy of the commons” — the place people and entities with entry to a public useful resource act in their very own curiosity and deplete it.
Decentralization seems to be a trade-off that these VC-funded Lightning corporations are prepared to make, which is a significant concern to Riard.
“Centralized programs are nice within the scale of effectivity, nevertheless they arrive with the draw back of systemic single-point-of-failure and decrease price of consumer censorship, elementary dangers that one would possibly want to hedge towards as a Bitcoiner.”
“I am not positive that is an fascinating Lightning future,” Riard stated. The truth is, it’s one thing which he desires no a part of, after departing from the Lightning ecosystem on Oct. 20:
“I do not want to be related to being in cost or accountable of the Lightning Community security, and the ~5,300 BTC uncovered right here. There may be little [I and others] can do to halt the haemorrhage, with out compromising the core values of censorship-resistance and permissionless of the Lightning Community.”
Lightning is the very best answer at present accessible, however it’s not adequate.
Lightning has a number of elementary flaws, the place every of them make the system as an entire a useless finish for bitcoin, long run. An try at explaining these, and what we must always do as a substitute.

The Lightning Community is the second-layer answer constructed over the Bitcoin blockchain. It’s designed to enhance the scalability and effectivity of Bitcoin.
By means of the Lightning Community, customers can open fee channels, conduct a number of transactions off-chain, and settle the ultimate consequence on the Bitcoin blockchain. The alternative biking assault is a brand new sort of assault that enables the attacker to steal funds from a channel participant by exploiting inconsistencies between particular person mempools.
Cointelegraph reached out to Lightning Labs and different corporations within the Lighting ecosystem however did not obtain a response.
Do not get me incorrect right here: Lightning is nice! At all times nonetheless amazed when utilizing it.

Nonetheless, regardless of the security considerations and potential transfer towards centralization, Riard defined that Lightning hasn’t seen as many assaults as many Ethereum layer 2s as a result of Lightning customers usually solely retailer a small quantity of funds of their wallets at any given time.
