Does the Lightning Network still hold a future?

[Abiky]

The controversial L2 scaling solution has been years in the making, yet it has suffered from lack of mainstream adoption. At the time of this writing, there are many merchants and/or services that still don't support LN payments. For something that promises ultra-low fees and blazing-fast transaction speeds, LN should've been accepted almost everywhere by now. Imagine going to your favorite coffee shop or restaurant and paying with the LN like a breeze.

While the LN does have its benefits, it isn't the perfect solution. There are many flaws that need to be addressed. Especially in terms of UX, and high centralization risks.

What do you think? Is there still a future for the LN? Or is it game over? Your input would be greatly appreciated. Thanks.

If you ask me I won’t say it’s a game over for lightning, but I also don’t think we should expect it to become the universal payment method anytime soon.
The biggest challenge with the LN is not really with the speed or fee. Obviously those are already impressive. The challenge is the UX. most normal users don’t want to understand channels, liquidity, routing, backup, or why payment suddenly failed. If paying with bitcoin requires understanding all of that, mainstream adoption will always be difficult.
Centralization is also a valid concern, lightning isn’t inherently centralized, but there are more incentives for liquidity and routing to concentrate around larger, well connected nodes. That’s something the ecosystem need to keep watching carefully.

IMO, lightning still has a future, especially for small and frequent payments where putting everything on-chain doesn’t make sense. But it success will depend on whether the developer can hide most of the complexity from the user while still preserving bitcoin’s self custody and permissionless nature. If that can be solved then it’s worth not writing LN off yet.

It’s not that every merchant need to run their own Lightning node to make LN payment success.



Look at this, Square is integrating Bitcoin payment at much larger scale for eligible merchant, where merchant don't need to manage Lightning infrastructure themselves. That mean a portion of adoption is happening on backend, which is invisible to the user.

But I get your main point. Hmm, Lightning's UX is still not as simple as Bitcoin on-chain.

In my opinion, Lightning definitely has some future, but its future may not be a model where everyone has to run their own node and every store need to accept LN directly. Such complexity can be hidden from user through infrastructure of wallet, exchange, payment processor and application.

LN could still work. Imo, the because hurdles are the underlying UX and lack of enough integrations across the board. If users know the benefits of LN and they know that they can access those benefits directly on any app they're using to send or receive Bitcoin, they can start utilizing it. Look at Segwit, most people know the benefits and it's support on like 90%+ of service providers from wallets to exchanges. But it's not the same as LN

I guess you brought up this discussion because the Bitcoin network fee is very cheap at the moment. You want to know how important LN is? Wait until the mempool is clogged, and then we can have this discussion. LN usage may not be as popular as you expected, but that does not mean it's not serving its purpose or it has no future.

Great point, lightning use to become much more valuable when mempool becomes congested and when on-chain fees rises. I would really say that the judging of LN by how popular it is today it one of the biggest mistakes, it values is to give Bitcoin an option for a frequent small payment, without having to go put each transaction direct on base layer. Also liquidity issues and UX needs to be improved, all this aren't the reasons for lightning development it not a reason to write it off .

Merchants are being offered alternative networks (coins) that also provide low fees and simple setup, along with off-ramp capabilities; so it makes sense that the LN is not a priority, given that most business needs do not strictly require a long-term store of value.
However, the Lightning Network will have a future of its own, for instance, in serving businesses that do not require rapid capital turnover.

Hmm, many merchant still do not support LN, because it is difficult for ordinary user to understand channel, routing, etc.

Square is integrating Bitcoin payment at much larger scale for eligible merchant, where merchant don't need to manage Lightning infrastructure themselves. That mean a portion of adoption is happening on backend, which is invisible to the user.

Not only Square, Lightning Labs is also creating tooling that makes it easy for developer to integrate self custodial Bitcoin payment without having to manage Lightning infrastructure themselve. The UX is gradually becoming easier. Merchants no longer have to run node themselves. Users just scan the QR and pay, and the rest is done on backend.

Afaik, LN's public capacity is around 5000 BTC now, and the monthly volume has risen to over $1 billion.

Actually, LN doesn't seem urgent because on-chain fees are low now. Let a few more years pass, and the real value of LN will be seen only when the mempool is jammed. Especially for small and frequent payments.
