Ignoring the issues of the Lightning Community and protocol stack appears to be a very fashionable factor to do lately. It’s presently essentially the most broadly adopted and used second layer of the Bitcoin community, and the quickest transferring by way of additional improvement. It additionally has plenty of shortcomings which are straightforward to brush below the rug and work round, on condition that it is extremely small and at a really early stage of adoption. However that doesn’t make these issues go away, or change the fact that at a a lot bigger scale and additional alongside the adoption curve these issues turn out to be very actual ones that require precise scalable options.
One of many issues on the core of Lightning is the difficulty of receiving liquidity. It isn’t potential to obtain any funds over the Lightning Community with out first having secured receiving liquidity from another person’s node. It is a basic and unavoidable limitation of utilizing the Lightning Community in a non-custodial method. Clearly, utilizing issues like Pockets of Satoshi or Bluewallet’s default LNDHub (that are custodial) you may hack round this downside, however that’s solely as a result of another person has solved it for you and you aren’t really in charge of your funds. When coping with issues self-custodially although, you need to really handle the issue.
When the Lightning Community first went reside and started seeing actual use through the “#Reckless” period, this downside was addressed very informally. It was primarily solved by means of social connections; by means of requests to folks you knew or shut buddies; by means of handshake agreements “Hey good friend, are you able to ship me some liquidity, I simply spun my node up.” There have been no marketplaces, there have been no companies to make use of, it was actually simply buddies serving to one another out. Even in the present day, by means of issues like PLEBNET, a big proportion of the liquidity sourcing occurring on the community is happening in these sorts of casual social preparations.
The community remains to be very small, and nonetheless confined to what on a social graph is a small set of actors that even by means of oblique levels of separation usually are not that far aside from one another. I’d say that we’re simply beginning to enter a section of development in the present day the place the scale of the community and the variety of folks concerned are beginning to get to the purpose the place such a association and dynamic is not sustainable.
The subsequent section of development in fixing this downside occurred not too lengthy after the community went reside. Providers like LNBIG started establishing a web page the place folks might request incoming liquidity. Bitrefill started providing channels with receiving liquidity as a service (and within the course of created their “Turbo channel” spec which lets you use a channel even earlier than it’s confirmed on chain). Coincharge, Voltage and lots of different firms provide comparable companies as effectively. Paying a price, you may merely have a enterprise open a channel with you to offer receiving liquidity with a view to be despatched cash. This step within the evolution of issues occurred to resolve a form of scaling downside since not all the new customers approaching board had these social connections to get incoming liquidity. Even when they did, folks solely have a lot cash they will allocate to channels for folks they know. It’s also possible to not count on folks to sit down round all day, always be able to open channels when folks want liquidity. So, a enterprise has room to step in and remedy the issue for a price.
You even have the dynamic of lightning service suppliers (LSPs) like Breez stepping in and themselves offering a specific amount of receiving liquidity for his or her customers. This, nevertheless, nonetheless runs into the identical common issues as sourcing issues from folks you recognize: Breez solely has a lot cash they will allocate to their customers to obtain funds. They do make routing charges by being the node you’re related to, however ultimately they’ll run into the difficulty of getting to handle a finite quantity of funds throughout a rising consumer base. This isn’t sustainable in perpetuity.
The subsequent kind of answer for this core downside of Lightning was precise marketplaces. Not a enterprise promoting you their very own funds within the type of receiving capability, however a market the place anybody can come and provide to promote receiving liquidity to anybody wishing to buy it. Two examples of this answer are Lightning Lab’s “Lightning Pool” public sale home and Amboss’s Magma marketplaces. Lightning Pool even enforces a minimal size of time the bought channels should stay open on chain by means of a CLTV timelock. These are each non-custodial methods for a central celebration (Lightning Labs and Amboss) to match folks eager to promote with these wanting to purchase inbound liquidity. The issue is that they’re nonetheless depending on a centralized facilitator to make this work. Lightning Lab’s and Amboss each really cost a price to take part of their auctions.
A remaining class of options to this downside is embodied by CLN’s Liquidity Adverts, a decentralized market for receiving liquidity constructed on high of dual-funded channels (the place either side of the channel present liquidity on funding as an alternative of only one). Liquidity Adverts makes use of the Lightning Community’s gossip protocol which advertises public channels out there to route funds by means of with a view to publicly submit commercials that you’re prepared to promote receiving liquidity. Identical to Lightning Pool, it additionally enforces a “lease time” that the channel should stay open for with a CLTV timelock on chain.
So, all of those completely different choices depart one query hanging within the air: how do we actually wish to method fixing this downside in the long run and at scale? It’s actually not potential to obtain funds over the Lightning Community with out first sourcing receiving liquidity. That could be a core limitation of the protocol itself. Can we wish to remedy this downside on the stage of the protocol itself, seeing as that’s the place the present limitation is, or will we wish to lean on centralized companies and marketplaces to take action?
When it comes all the way down to it this can be a query of community impact, and a chicken-or-egg downside. Consumers wish to go the place sellers are, however sellers are additionally going to wish to go the place consumers are. If we lean arduous into centralized marketplaces or companies to resolve this downside, then ultimately that community impact will compound and turn out to be increasingly tough to beat with decentralized protocol-based options. So this can be a essential query for customers to be asking themselves now. Can we let this large shortcoming of the Lightning protocol stack be solved solely by centralized enterprise companies, or will we try to resolve it on the protocol stage itself?
Personally, my pondering is that given the necessity for inbound liquidity is completely required to make the most of the protocol in a self-custodial means, this downside ought to be addressed on the protocol stage. And as a final be aware, to resolve this on the protocol stage in a decentralized means nonetheless lets present companies and centralized options compete overtly through the use of that protocol themselves.
