Avg Channel Size

What this measures

This chart divides the total capacity of public Lightning channels by the number of those channels. The result, expressed in bitcoin (BTC), is the average amount of funds locked in a single channel. Both underlying series, network capacity and channel count, come from mempool.emzy.de, which monitors Lightning’s public graph. Because it is denominated in BTC rather than dollars, the metric does not move with the price.

An average that describes no real channel

Funds on Lightning are very unevenly distributed. A few large routing nodes, often run by companies, open channels worth several bitcoin between one another, while most public channels stay small. Those large channels pull the average up: the median, which this chart does not show, usually sits well below it. In practice, the “average” channel does not exist.

The calculation also has blind spots. Private channels, never announced to the network, are left out, including many of the channels that self-custodial mobile wallets open with their liquidity provider. And a change can come from the denominator alone: closing a large number of small channels is enough to push the average up without a single extra bitcoin entering the network.

A network organizing itself around its largest nodes

The history of this curve carries the mark of a technical choice. Lightning’s specification originally capped a channel at 16,777,215 satoshis, roughly 0.168 BTC. The so-called “wumbo” option, later adopted by the main implementations, lifted that limit.

A rising average points to the professionalization of routing more than to broader adoption. Operators commit significant liquidity to forward other people’s payments and earn fees from it. The network becomes more reliable for large amounts, but that does not mean it is decentralizing. The more routing depends on a few well-funded nodes, the larger the share of payment flows those nodes see, even though onion routing only reveals the previous and the next hop to them.

🪙 What is the Ark protocol? The missing piece to make Bitcoin a scalable everyday currency

On the user side, recent wallets increasingly avoid channel management altogether and hand liquidity over to a service provider. The complexity does not go away; it ends up with those who can afford to carry it.

A rising average can signal a sturdier network just as easily as a network resting on fewer shoulders.
