Through the traditionally vital block dimension debate that raged by the Bitcoin userbase from 2015 to 2017, a key space of rivalry surrounded the concept of how bitcoin (BTC)-denominated funds will scale to a world userbase.
Whereas some main miners, exchanges, pockets suppliers, and different customers needed to see a tough fork to extend capability for on-chain funds, the most important contributors to Bitcoin Core and different customers thought it could be a greater concept to attempt to maximize use of the then-available block area restrict earlier than choosing a backwards incompatible change that would probably break up the community.
The tip results of this debate was the adoption of Segregated Witness (SegWit), which paved the way in which for the Lightning Community to develop as a secondary funds layer for the bottom Bitcoin blockchain.
Whereas there was some adoption of this layer-two (L2) Bitcoin community in numerous varieties, drivechain inventor and LayerTwo Labs CEO Paul Sztorc just lately referred to Lightning as a “large failure,” which sparked some debate on X.
This isn’t essentially a brand new place from Sztorc, as he’s written somewhat extensively about Lightning’s shortcomings and makes an attempt to blackpill Lightning fanatics at any alternative.
So, is there advantage to Sztorc’s claims relating to the Lightning Community? Let’s take a more in-depth have a look at a latest debate Sztorc had with the Human Rights Basis’s Alex Gladstein on What Bitcoin Did, along with some further, clarifying feedback Sztorc shared with Protos.

Follow vs. idea
A lot of the disagreement between Sztorc and Gladstein relating to the success or failure of Lightning Community has to do with how the BTC-denominated funds protocol works in follow at present compared to the way it theoretically might not work so nicely over the long run.
On the one hand, Gladstein pointed to quite a few examples of how the community is offering worth to customers at present, reminiscent of Nostr Zaps, adoption by massive exchanges like Binance and Coinbase, and the upcoming integration for Sq. retailers.
Moreover, a lot of Gladstein’s work with the Human Rights Basis happens in areas the place the lack of know your buyer and anti-money laundering restrictions on Bitcoin have been a boon to adoption for individuals who want it most.
Moreover, Gladstein says there have been large enhancements made to the Lightning Community’s usability up to now 5 or 6 years.
“From our perspective, what you’re saying couldn’t be farther from our expertise,” he instructed Sztorc throughout their latest debate.
In distinction, Sztorc sees these examples of real-world use as largely irrelevant to his underlying level of the system not being scalable or workable over the long run.
Notably, he explicitly pointed to the elevated charges attributable to the Ordinals Inscriptions phenomenon for instance of how the Lightning Community can begin to buckle underneath strain.
To Sztorc’s level, the Lightning Community does have a difficulty the place reverting to the Bitcoin blockchain or opening a low stability self-custodial Lightning channel within the first place can develop into uneconomical in high-fee environments.
Sztorc prefers his personal resolution, referred to as drivechain, over the Lightning Community. A drivechain is a kind of Bitcoin sidechain the place the BTC is successfully managed by the miners.
To be clear, Gladstein said that drivechains are an attention-grabbing concept; nonetheless, he additionally identified that the truth that they’re strictly theoretical at this level attributable to their lack of existence on Bitcoin’s mainnet.
Sztorc has revealed a number of Bitcoin Enchancment Proposals (BIPs), notably BIP 300 and BIP 301, relating to the drivechain idea, however there hasn’t been a lot traction when it comes to activating the mandatory tender fork for the change, whether or not that be by Bitcoin Core or another tender fork activation consumer.
Drivechain critics, reminiscent of Bitcoin Core contributor and OpenTimestamps founder Peter Todd, say Sztorc’s concept can negatively have an effect on Bitcoin on the base layer, regardless of the supposed purpose of drivechain to behave as an answer for secondary protocol layers.
Sztorc has revealed responses to widespread criticisms of his invention in FAQ format.
“I don’t assume it’s assured to work, however I do assume, relative to the [interest or hype] Lightning will get, it’s completely mismatched,” Sztorc stated throughout the debate.
He additionally analogized drivechains to “teleporting to the end line” of Bitcoin’s eventual scaling roadmap.

Why doesn’t the Lightning Community work?
Once more, to be clear, Sztorc admits that the Lightning Community can work at present on a small scale. It’s over the long run in a larger-scale state of affairs the place he sees extra severe points.
He even defined how he was initially very within the Lightning Community when it was first revealed — he even constructed a design for SPV fraud proofs that use the Lightning Community.
Nevertheless, he’s develop into way more disillusioned over time.
Sztorc summarized the technical points with the Lightning Community at one level throughout the debate as follows:
- There aren’t sufficient bytes on Bitcoin’s layer one to onboard everybody
- There’s counterparty threat as a result of Lightning channels can lock a person’s funds for 2 weeks and even steal funds underneath sure situations
- The inbound liquidity downside is counterintuitive and creates an costly, horrible person expertise
- Excessive on-chain charges trigger points for onboarding and Lightning’s safety ensures, as was seen when the Ordinals phenomenon prompted excessive charges on a number of events
- A lot of the adoption Lightning has achieved is through custodial techniques, which has tricked folks into pondering Lightning is best than it truly is
- Adoption continues to be low regardless of the custodial Lightning shortcut
- Privateness is horrible
In one other part of the talk, Sztorc additionally briefly touched on the truth that BTC miners are those who resolve which legitimate transactions get included in blocks.
As such, they could have a bit of additional energy when it comes to influencing customers to desire a mannequin the place they receives a commission for all transactions on secondary networks, reminiscent of drivechain, over one thing just like the Lightning Community.
“They’ll have the problem that both the massive miners will need to vertically combine, or they’ll have some kind of tug-of-war battle over who can get that cash, at which level a number of the safety mannequin will go away,” Sztorc defined.
Whereas there may be loads of work being achieved by researchers and builders to resolve lots of the points cited by Sztorc, his final critique is that the Lightning Community was offered because the be-all and end-all for all of Bitcoin’s issues.
He went so far as to check claims that Lightning’s present technical challenges have been all the time recognized and the system was by no means supposed for use by all finish customers to the mantra of “We now have all the time been at conflict with Eastasia” from the novel 1984.
In step with Sztorc’s critique, a rising variety of folks now view the Lightning Community much less as an answer for on a regular basis finish customers and extra because the connective infrastructure between various secondary layers within the Bitcoin ecosystem.
“That’s a mistake I made,” admitted Gladstein throughout the debate. “I assumed that was the case, after which I modified my thoughts based mostly on proof.
“I feel now that Lightning goes to be this central nervous system-type community that exists between what the top customers use, and the on-chain [users], and companies, and exchanges, and every thing. They’re all going to talk to one another by this open financial community that’s Lightning.”
In fact, this brings up one other space of rivalry for Sztorc, as he doesn’t see the custodial or federated techniques which are stay on Bitcoin at present as acceptable secondary layers that retain the basic properties that make BTC beneficial within the first place.
And to be honest, many different Bitcoin customers, who are likely to view self-custody as a paramount property of the system, agree with Sztorc right here.
“The federated mannequin is simply in regards to the worst factor to occur in Bitcoin’s historical past, I feel,” stated Sztorc throughout the debate.
“So, it’s attention-grabbing that you just’re so blasé about what it means. The federated mannequin principally means: I’ll provide you with all of my cash instantly, and I’ve no recourse about ever getting them again.”
Sztorc identified that there are options to the federated mannequin that supply higher financial ensures for finish customers, together with his drivechain idea.
Once more, Gladstein is open to raised fashions, but in addition appears enthusiastic about expertise that takes benefit of how Bitcoin works at present, reminiscent of Chaumian ecash protocols like Cashu enabling a a lot increased diploma of person privateness.
There’s a clear disagreement on this level, with Gladstein seeing the techniques which are already attainable as helpful and underrated, whereas Sztorc doesn’t see the purpose of spending time on such centralized choices.
With out opening a technical can of worms that’s out of the scope of this text, it must also be famous that miners can nonetheless technically steal person funds from a drivechain; nonetheless, Sztorc argues that financial incentives forestall them from doing so.
In fact, there’s no purpose drivechain can’t be mixed with the Lightning Community. On this state of affairs, Lightning continues to be used because the connective tissue between completely different layer-two networks, of which a number of drivechains are an possibility.
When requested about this level particularly by Protos, Sztorc said, ”It’s attainable to make use of Lightning on every drivechain, and in the event that they every assist a standard hash algo (ie sha256 — that is principally 100% assured) then actually they’re all interoperable.
“If somebody alongside the route has a channel on two or extra networks, then they robotically bridge the hole.”
Sztorc added that he beforehand believed a drivechain may very well be helpful for testing out new Bitcoin options which are related to the Lightning Community, reminiscent of SIGHASH_ANYPREVOUT, earlier than they make it to Bitcoin’s mainnet, successfully providing early entry to new Lightning options.
Close to the top of their debate on What Bitcoin Did, Gladstein pleaded with Sztorc to be extra open to working with different tasks, however his conviction in drivechain clearly leads him to usually view different tasks making an attempt to resolve related points as wastes of time.
“Why can’t we take the center floor and simply say [Lightning] is rising, it’s not excellent by any stretch, [and] it has bugs,” stated Gladstein. “But it surely’s getting higher on a regular basis.”
“I feel we sorta did find yourself agreeing, on the finish,” Sztorc later instructed Protos. “I lastly wore them down! Slightly.”
