Is there a source to check total LN transaction activity and volume over time?
reply
Nope ... and that is a good thing - nobody will know exactly how much is transferred in real time over LN.
Keep in mind that we have public and private nodes.

I see your point. Private nodes, private channels,etc, but there are heuristics that can give rough approximations at least on a comparative basis, right? Like this: https://bitcoinvisuals.com/lightning
I guess what I'm asking is are you confident that LN growth fully explains low transaction costs now?
reply
These stats are showing / guessing only the public nodes capacity but not also the number of txs done through those channels, not counting also the private channels that cannot be counted.
A simple question: how many users of private nodes like Zeus, Phoenix, Blixt, Mutiny, Breez, Electrum you can estimate and let's say each one could have at least 2 channels.
Most of the txs are done from these private nodes, not from public nodes. Public nodes are mostly routing these private txs, but they will never know how many.
Is not LN a beauty because nobody could really measure it / trace it ?

This is not 100% the cause. Take in consideration also these aspects (and you can see it with mempool glasses):
  • NFTs/ordinals are done, they are empty pockets and can no longer sustain that useless traffic. This was more than 50-60% of the traffic.
  • coinjoiners are no longer doing endless mixing (IMHO no longer necessary)
  • big exchanges were already consolidate their garbage and no longer doing massive traffic with huge fees. Many of them are using bad code not using efficiently the fees and types of BTC addresses
  • exchanges now are offering LN withdrawals that help a lot
  • batching txs and batching opening channels are now more efficient and we have tools
That's why I am saying that LN helped a lot in reducing the onchain traffic. But don't worry, the high fees will come back.

Great answer! Thanks. I was thinking about the NFT crap disappearing. I forgot about the likely end of mixing/conjoins.

conjoins Haha, was that intentional 😆

Great answer!

Not directly, but you can use channel closures as a heuristic.

Do you have an opinion on the reason for the low on chain fees?
reply
Simply supply and demand.
reply
Sure, but wouldn't you expect demand to be pretty high right now considering everything that is going on?

The shitcoiner's blockspace budget is currently being spent on boothspace @ $46/ft^2
IMO cheap blockspace is the normality.

hahaha good one

But this convo+shower gave me an idea: representing the fee market as candlestick data.
Not sure how opening and closing would be calculated, but high/low/volume is easily transferable.
