Lightning is doomed. Excessive charges from Ordinals have killed all hope of scaling Bitcoin non-custodially, there isn’t a probability in any respect that folks will be capable to cheaply open channels or implement hung funds on-chain when needed. It’s throughout, pack all of it up guys. Time to begin procuring round and deciding whether or not Coinbase or Cashapp is a greater platform for all of our Bitcoin wants now that we will’t afford to do it immediately on-chain in a excessive charge atmosphere.
It was enjoyable whereas it lasted. We’ll all the time have the pixelated dick pics on the Lightning artwork web site, the Lightning torch meme the place everybody was scared to ship it to individuals in nations the state instructed us is filled with nothing however dangerous individuals, we’ll nonetheless have the zapping sats from custodial account to custodial account. Into the period of walled gardens we go!
In the event you took any of that significantly on any stage go take a look at your self within the mirror, after which give your self a great arduous slap within the face.
Clearing The Gaslighting Fumes
The unique Lightning Community whitepaper particularly outlined within the conclusion to the paper that for 7 billion individuals to have the ability to open two channels a 12 months Bitcoin would require 133 MB blocks.
There’s a whole part of the whitepaper referred to as “Dangers” (Part 9), that spells out the entire main issues individuals suppose means Lightning is “doooooooooomed” due to excessive charges. The primary part of the paper discusses timelock home windows. “Improper Timelocks.” That is basically the dynamic of charge charges versus affirmation time that has change into a big concern these days. Whenever you route a fee over the community, you outline successful path primarily based on a hashlock preimage, and a clawback path primarily based on the refund timelock window. If charges get increased, that timelock window must be longer to ensure {that a} preimage spend (the transaction succeeded) does not fail to verify earlier than a refund transaction turns into spendable.
I.e. if you need to affirm a profitable fee on-chain the timelock on the refund path needs to be lengthy sufficient you could affirm the profitable fee path earlier than your channel counterparty can declare the funds by means of the refund path. How lengthy that timelock window needs to be will increase the upper feerates get, as a result of the transaction charge determined forward of time for pre-signed channel closure transactions might be too low to verify as quick as you anticipated once you signed them.
Many individuals are freaking out and dropping their shit over this dynamic as whether it is some new realization, and it spells the doom of the Lightning Community. This was actually described as a threat within the unique whitepaper specifying the primary model of the Lightning protocol. It explicitly even described the chance value trade-off from an financial standpoint: “There’s a trade-off between longer timelocks and the time-value of cash.”
The following part is known as “Compelled Expiration Spam.” It describes the final idea of the Flood and Loot Assault. An adversary opening a lot of channels and shutting them unexpectedly on-chain, particularly to benefit from the truth that if the feerates bought too excessive refund transactions may have an opportunity at double-spending success path transactions if one thing wanted to be enforced on-chain. If in case you have a bunch of channels open with funds in mid-flight, and also you shut them unexpectedly and drive charges up excessive sufficient, then each channel counterparty who has to verify a profitable fee on-chain may discover themselves in a doublespend race if the charges are pushed up excessive sufficient to let the timemlock transaction change into legitimate earlier than the profitable one with the preimage is confirmed.
If in case you have sufficient channels open, and drive charges up excessive sufficient, you possibly can revenue from this. It was actually described within the whitepaper as an architectural concern. Relying on which model of the paper you rely, this class of assault was described in 2015-2016. It wasn’t formally modeled and launched into the information cycle of this house till 2020.
The whitepaper described knowledge loss, the scenario of dropping the pre-signed closure transactions and penalty keys for previous states that will enable a malicious channel counterparty to steal your funds in the event that they had been conscious of this. It introduced up the scenario of being incapable of broadcasting a penalty transaction, and the potential for watchtowers to unravel this as a 3rd occasion being paid to look at the blockchain and submit these transactions in your behalf. It actually described miners censoring channel penalty transactions as a threat, and instructed miner anonymity (and implicitly decentralization) because the mitigation for that threat.
However that is all new info. The Lightning Community is doomed to failure as a result of nobody noticed any of those issues coming!!!!
The Blockchain You Idiots
Effectively, I assume we will simply admit historic context is misplaced. Motive is misplaced. Logic and rationality is misplaced. We’re in a actuality the place we’re going to fake like historic warnings do not exist, nobody ever identified apparent issues destined to manifest sooner or later, and that is all simply completely uncharted territory the place nobody ever considered how issues would play out.
What’s the title of Part 9.6? Oh: Incapability to Make Obligatory Delicate-Forks.
The unique whitepaper explicitly spelled out the lack to coordinate gentle forks as a threat to the success of the Lightning Community. Are you shocked? Have you ever by no means learn any of this earlier than? Personally I am getting déjà vu.
I bear in mind years and years in the past, a big contingent of Bitcoiners screaming that the blockchain itself was hitting scaling limits, that it might fail until we basically altered the whole nature of the decentralization trade-offs of the system. Blockchains had been basically ineffective if individuals could not immediately submit all of their transactions on-chain and have them cheaply confirmed.
The complete basis of the Bitcoin ecosystem was rocked to its core when individuals began arguing over the associated fee effectiveness of the blockchain at scale, that was actually the whole reason for the blocksize battle. What was on the core of this disruption? Individuals’s expectations of what function the blockchain would play within the puzzle of Bitcoin’s evolving ecosystem. Everybody goes to purchase their espresso on-chain at a cheap feerate, or Bitcoin is a complete failure.
Everybody with that mentality simply fully misjudged the whole scenario. They had been making an attempt to stuff a sq. peg right into a spherical gap. It is the very same factor with Lightning.
Sq. Peg, Spherical Gap
The blockchain was sorely misjudged, it was actually only a place to place channel openings and closings, not a spot to purchase your espresso. There is no actual probability that folks misjudged Lightning although, that’s absolutely the place to place your espresso funds. Nobody may probably have misjudged that this time. See how foolish that sounds once you put it like that in correct context? Lightning has points with imposing funds on-chain; if the worth of the fee is lower than the charge to submit the transaction to the chain, this can be a drawback. It makes no financial sense to attempt to implement it on-chain. This was a really well-known drawback. It is basically the very same drawback of low worth funds occurring immediately on-chain, besides within the optimistic case issues simply work as a result of individuals cooperate off-chain. However after they do not cooperate, there are issues.
This drawback was so well-known that there was truly a great deal of debate years in the past a couple of answer to it with totally different trade-offs, packetized funds. If an HTLC is simply too small to have the ability to implement trustlessly on-chain, you possibly can stream a fee sat by sat (or bigger chunks of sats) in a trusted method, and cease streaming and choose one other route if somebody in a hop decides they will steal a sat from you. The thought is that whereas it’s a trusted fee routing mechanism, you possibly can solely lose a number of sats to an attacker who steals a tiny piece of your fee, and if somebody steals from you whereas routing a fee you simply by no means route by means of these nodes once more. The quotation above is from 2019, however this concept was mentioned sooner than that.
Lightning has an issue! (And in addition an answer to that drawback most individuals studying most likely by no means heard about). All of those points individuals appear to suppose means the sky is falling are points effectively understood from the very starting of Lightning. This begs a query: had been we mistaken once more?
Not mistaken within the sense that Lightning is a doomed lifeless finish, however mistaken within the sense that Lightning isn’t going for use long run in the best way we thought it was initially, similar to the blockchain itself. We already see Lightning dominated by custodial purposes, and individuals are engaged on deploying issues particularly designed to sit down on prime of Lighting. Chaumian ecash mints, Uncle Jim setups like LNBits the place individuals are given a custodial account on somebody’s Lightning node. We even have proposals like Ark being constructed out within the proof-of-concept part on Liquid, which may work together atomically with Lightning funds.
What if Lightning is not going to be the killer protocol that customers immediately work together with so as to make their funds on-line? What if, similar to the blockchain itself, it merely winds up being a bit of a settlement layer that different issues are constructed on prime of?
Would that be the top of the world? Would that be a failure of Lightning? I might argue completely not. From the very starting of growth on Lightning it was extremely clear what its scaling limitation could be. The whitepaper actually brings up the problem of not getting assist for softforks wanted sooner or later as a limitation of Lightning’s potential scalability.
Lightning is proving definitively proper now that it will probably operate as a layer for interactivity between totally different custodians, and that it really works easily and really successfully for that. There is no such thing as a cause in any respect Lightning can not operate as the same connectivity layer for different layer twos which have superior belief fashions than a specific custodian. If channels should not one thing people can cheaply have for his or her day by day spending exercise, that does not imply they aren’t value efficient for LSPs who run new protocols along with Lightning to hyperlink between one another, permitting their customers to work together with one another. Arks, Statechains, and no matter new concepts individuals develop over the approaching years.
It may be a translator layer for different methods that scale the top customers capability to onboard and transact on these layers, precisely like we wound up realizing the blockchain must be. And there’s nothing mistaken with that.
