Lightning has been on an explosive development tear currently by way of extra liquidity coming to the community. Because the begin of 2021, the community has grown from 33,000 or so channels to greater than 65,000. The quantity of bitcoin in these channels has grown from round 1,000 BTC to nearly 2,500. That is extensively considered as a large indicator of success, and it’s, however it’s beginning to illuminate a rising divide in perspective about what’s going to really dominate the incentives of particular person node operators sooner or later. This speedy development has led to a diminishing return in routing charges for node operators, and a few of them don’t care.
Because the launch of PLEBNET (to not say that is causally associated, simply when it began coming to my consideration), I’ve been seeing increasingly Lightning node operators espousing the perspective that they don’t care about incomes routing charges for working their node. This stands in full distinction to all of my long-term occupied with how the Lightning Community will evolve financially. And I don’t imply “don’t wish to earn a revenue” in routing, I imply actually not charging routing charges. This appears utterly irrational by way of financial incentives, and for any misrepresentation of the explanations individuals wish to run a node like this I apologize. To me it looks as if individuals wish to interact on this habits out of a way of altruism and to take care of Lightning as a “pleb-owned” piece of monetary infrastructure. I don’t see this as economically sustainable.
Typical Pondering Of Revenue Incentives
Earlier than we get into the dynamic of revenue, let’s simply take into account the price aspect of issues. With the intention to shut and open a Lightning channel you need to transact on-chain, which incurs a miner price. That is utterly inescapable and is the bottom value to enter or go away the Lightning Community. Now take into account the routing charges collected in relation to those on-chain charges, if the routing charges are in extra of on-chain charges, you pocket a revenue and if they’re much less you incur a loss. So clearly an economically rational node operator’s objective ought to be to maximise the routing charges they gather in a aggressive market in order that, earlier than the tip of a channel’s lifetime, they’ve earned extra in routing charges than they paid to open the channel and pays to shut the channel.
As extra liquidity enters the Lightning Community on common, the quantity in routing charges nodes will gather will go down, as we’ve seen for a lot of node operators throughout this 12 months’s large development of channels and liquidity. Now it’s just a little extra nuanced than simply “extra money = everybody makes much less cash,” as many individuals level out, channels and their liquidity usually are not fairly fungible. A channel open to a big service provider everybody frequents goes to have the ability to gather greater charges than a channel open to a random man named Bob some individuals often ship small funds to. However as extra channels are opened to that giant service provider, charges in these channels will pattern down as individuals attempt to competitively undercut one another on worth. That’s simply primary economics.
The best way I’ve at all times seen the Lightning Community evolving long run is financial competitors over inserting channels between nodes or entities which have excessive transactional demand. These that may do that affordably will earn a pleasant revenue, and people that may’t will, so to talk, “be put out of enterprise.” Additionally a final point out earlier than shifting on, clearly, on this mode of pondering, as on-chain charges enhance over time by necessity routing charges will enhance as nicely.
Now let’s take into account a routing node operator who is just not involved with earnings. I’m going to contemplate two subcategories right here, those that will not less than recoup their prices and those that is not going to even care about doing that.
Operators who nonetheless purpose to get well their prices will nonetheless must cost routing charges however, due to not caring to earn revenue on high of that, they are going to have the ability to undercut profit-seeking routing nodes by way of charges. It will inevitably result in such nodes attracting extra quantity than ones charging greater charges in the hunt for revenue and eat into the income of profit-seeking nodes. Now considering the dynamic of extra liquidity dragging down income, this might, doubtlessly, if a big sufficient variety of nodes function beneath such a mannequin, make it far more tough (or within the excessive, doubtlessly unimaginable) to earn a revenue routing transactions on Lightning.
Within the case of node operators who don’t even care about recouping their prices, the identical sort of dynamic with profit-seeking nodes exists however with two main variations: The nodes “distorting” the market on this method are literally in the long run going to incur a loss and the revenue searching for nodes due to that might really themselves be pushed into incurring losses to remain aggressive as an alternative of simply lacking out on earnings. Clearly although, this turns into a recreation of rooster within the excessive, and ultimately somebody has to blink. I don’t imagine for a second, particularly as charges go up, that somebody will simply, in perpetuity, proceed dropping cash to subsidize different individuals’s Layer 2 transactions.
Rounding It Off
There are some deeper nuances I’ve overlooked above simply to maintain the psychological fashions I’m describing easy, resembling route-finding heuristics which may deliberately search for routes that cost greater charges as an indication of upper reliability, channel rebalancing to delay touching the blockchain longer, and so forth however I believe, even contemplating all of this stuff, one main dynamic stays: These are two fully completely different financial faculties of thought by way of motivations and incentives to function routing nodes on the Lightning Community. They won’t exist in a vacuum, they are going to work together with one another in the identical market because the community continues rising. It will likely be attention-grabbing to see how that performs out.
