Lightning is doomed. Excessive charges from Ordinals have killed all hope of scaling Bitcoin non-custodially, there isn’t any probability in any respect that folks will have the ability to affordably open channels or implement hung funds on-chain when essential. It’s throughout, pack all of it up guys. Time to begin buying 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 straight on-chain in a excessive payment setting.
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 folks in international locations the state advised us is filled with nothing however dangerous folks, we’ll nonetheless have the zapping sats from custodial account to custodial account. Into the period of walled gardens we go!
When you took any of that critically on any stage go have a look at your self within the mirror, after which give your self a very good onerous 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 folks to have the ability to open two channels a yr Bitcoin would require 133 MB blocks.
There’s a whole part of the whitepaper referred to as “Dangers” (Part 9), that spells out all the main issues folks assume 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 payment charges versus affirmation time that has turn 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 verify a profitable fee on-chain the timelock on the refund path must be lengthy sufficient you could verify the profitable fee path earlier than your channel counterparty can declare the funds by means of the refund path. How lengthy that timelock window must be will increase the upper feerates get, as a result of the transaction payment 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 shedding 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 price trade-off from an financial viewpoint: “There’s a trade-off between longer timelocks and the time-value of cash.”
The following part known as “Compelled Expiration Spam.” It describes the overall idea of the Flood and Loot Assault. An adversary opening a lot of channels and shutting them suddenly on-chain, particularly to benefit from the truth that if the feerates received too excessive refund transactions might have an opportunity at double-spending success path transactions if one thing wanted to be enforced on-chain. When you have a bunch of channels open with funds in mid-flight, and also you shut them suddenly and drive charges up excessive sufficient, then each channel counterparty who has to verify a profitable fee on-chain might discover themselves in a doublespend race if the charges are pushed up excessive sufficient to let the timemlock transaction turn into legitimate earlier than the profitable one with the preimage is confirmed.
When you have sufficient channels open, and drive charges up excessive sufficient, you’ll be able to 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 area till 2020.
The whitepaper described knowledge loss, the state of affairs of shedding the pre-signed closure transactions and penalty keys for outdated states that may permit a malicious channel counterparty to steal your funds in the event that they had been conscious of this. It introduced up the state of affairs of being incapable of broadcasting a penalty transaction, and the potential for watchtowers to unravel this as a 3rd get together 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 urged 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. Purpose 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 thought of how issues would play out.
What’s the title of Part 9.6? Oh: Lack of ability to Make Essential Smooth-Forks.
The unique whitepaper explicitly spelled out the lack to coordinate delicate forks as a threat to the success of the Lightning Community. Are you stunned? 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 will fail except we basically altered all the nature of the decentralization trade-offs of the system. Blockchains had been basically ineffective if folks could not straight submit all of their transactions on-chain and have them affordably confirmed.
Your entire basis of the Bitcoin ecosystem was rocked to its core when folks began arguing over the fee effectiveness of the blockchain at scale, that was actually all the reason behind the blocksize struggle. What was on the core of this disruption? Folks’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 an economical feerate, or Bitcoin is a complete failure.
Everybody with that mentality simply fully misjudged all the state of affairs. 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 might 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 payment to submit the transaction to the chain, this can be a downside. It makes no financial sense to attempt to implement it on-chain. This was a really well-known downside. It is basically the very same downside of low worth funds occurring straight on-chain, besides within the optimistic case issues simply work as a result of folks cooperate off-chain. However once they do not cooperate, there are issues.
This downside was so well-known that there was really a great deal of debate years in the past a few answer to it with totally different trade-offs, packetized funds. If an HTLC is just too small to have the ability to implement trustlessly on-chain, you’ll be able to stream a fee sat by sat (or bigger chunks of sats) in a trusted method, and cease streaming and decide one other route if somebody in a hop decides they’ll steal a sat from you. The thought is that whereas it’s a trusted fee routing mechanism, you’ll be able to 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 downside most individuals studying in all probability by no means heard about). All of those points folks appear to assume means the sky is falling are points nicely understood from the very starting of Lightning. This begs a query: had been we fallacious once more?
Not fallacious within the sense that Lightning is a doomed useless finish, however fallacious within the sense that Lightning will not be going for use long run in the way in which we thought it was initially, identical to the blockchain itself. We already see Lightning dominated by custodial functions, 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 section on Liquid, which may work together atomically with Lightning funds.
What if Lightning is not going to be the killer protocol that buyers straight work together with with a purpose to make their funds on-line? What if, identical to the blockchain itself, it merely winds up being a chunk 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’d argue completely not. From the very starting of improvement on Lightning it was extremely clear what its scaling limitation can be. The whitepaper actually brings up the difficulty 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 may well 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 purpose in any respect Lightning can’t operate as the same connectivity layer for different layer twos which have superior belief fashions than a specific custodian. If channels usually are not one thing people can affordably have for his or her each day spending exercise, that does not imply they aren’t price 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 folks develop over the approaching years.
It may be a translator layer for different techniques that scale the top customers capacity to onboard and transact on these layers, precisely like we wound up realizing the blockchain must be. And there may be nothing fallacious with that.
