I understand and am aware of L2 solutions like lightning. My own startup uses Polygon (Ethereum L2) to store copies of user asset verification records.

Generally speaking, L2s are interesting because they all make compromises from the principals of blockchain (as you mention - but that's for another day). It's been interesting, to say the least, to watch some of the fundamental definitions and principals such as "decentralized" and "secure" get redefined over the years.

I use statistics for Bitcoin transaction volume in these comments for several reasons:

1) Bitcoin is more widely known than any other blockchain based technology.

2) It's (essentially) only used for payments so transaction volume is more easily directly compared to other uses. For example, Ethereum has roughly double the daily transaction rate of Bitcoin but it's not clear to me how to easily breakout payments for direct comparison to Bitcoin, Visa, etc.

3) I'd use Lightning transaction volumes if I could find them. Anywhere. I've researched this quite a bit and all I can find are posts like the ones you provided (from Lightning Labs themselves) or from places like the Dailyhodl, etc talking about how big all of the markets Lightning is going to take over are, how much potential there is, etc. The typical "by 2030 we'll be doing (insert astronomical number)".

If you have a reputable/reliable source for the number of transactions on the Lightning Network I'd love to see it. The amount of bitcoin on it, the number of channels, the number of nodes, etc make for some impressive looking graphs but I suspect the transaction volume (to me the only real number that matters in terms of adoption) is still extremely low. If it wasn't everyone in the blockchain sphere would be hyping that too.

Let's circle back - I use blockchain at my current startup. I had 200 GPUs mining Ethereum in 2017. I'm not anti-blockchain by any means. I bring up what I consider to be valid criticisms because the bubble inside a bubble wrapped in an echo chamber present in blockchain today isn't doing anyone any favors. The reality is that (zooming out) after 10 years blockchain is still a toy. If it has any chance of ever living up to the promise and hype at least some people need to step out of the bubble and ask themselves why it's actually been one of the most slowly adopted technologies in the last 100 years.

> why it's actually been one of the most slowly adopted technologies in the last 100 years.

That doesn't agree with the data I've seen for Bitcoin: https://twitter.com/woonomic/status/1356310219215699968?s=19

And "blockchain" is pointless outside of Bitcoin, which might explain why its adoption has been slow as a more general technology. The blockchain was created to solve a very specific problem related to Bitcoin's mission statement (as defined by Satoshi). With that problem solved by Bitcoin, what else is there to use "blockchain" as a technology on exactly? Ok, there might be some very niche use cases that are applicable, but those aren't going to see the technology widely adopted.

I don't think it's actually possible to determine this. There's no way to see transactions that occur across the entire network. Nodes are only aware of the transactions that route through them. Maybe some clever people have determined a way to infer it, but I'm not aware of any. The metric most people use to judge growth of the Lightning Network is btc capacity i.e. how many bitcoin are "held" in channels between nodes, which is open information.

That's an interesting graph. They appear to have cherry picked data and used strange start dates for each. Based on numbers I've seen it looks more like this:

Bitcoin launched 1/2009 - as of now there are 100M users (your graph says 135M, which seems to be a very high estimate but lets go with that).

World Wide Web was released 4/1993 - 13 years later there were at least 700M users (very conservative estimate). Mind you this growth depended on everything from having a computer (22.9% of US households had a computer in 1993) to laying untold miles of fiber optics, undersea cables, building out physical datacenters, etc. Literally people digging ditches and ships circling the globe - many thousands of miles over.

By being essentially just another internet application (most people consider WWW = internet) taking advantage of all of this infrastructure Bitcoin/blockchain had/has a HUGE advantage over the WWW. To be a bitcoin user in 2009 you had to have a computer and install a program. To be a bitcoin user for the vast majority of its life you could/can hear about bitcoin at a bar, pull your phone out, and install an app on your smartphone to be a "bitcoin user" for next to nothing in under five minutes.

To be a WWW user in 1993 you had to have a computer that could handle it (Windows? Trumpet Winsock?, CPU, RAM, modem, etc) and a local ISP, etc. I remember in 1994 having to install a modem, a second phone line, and dial into an ISP that was LONG DISTANCE... It literally took weeks to get on the internet in 1994 and especially in my case, it was very expensive and very technically challenging (Hayes commands anyone? Chat scripts? PPP/SLIP?).

Then a little later America Online (still crazy expensive), maybe have it at work or university, or in the later years get lucky and have broadband in your area. I couldn't get DSL until 2004, for example (and it was still very expensive).

Even with all of these monumental challenges the WWW grew at least 5x faster than bitcoin (and it's really probably closer to 10x).

I suspected that was the case with Lightning. I'll keep digging into this because as I'm sure you can tell I'm fascinated with this. Overall I'm really trying to ask:

Why has adoption in the "cryptosphere" been so terrible (arguably the worst rate of any recent technology)? This is a question every honest blockchain advocate needs to ask themselves because there are clearly significant issues impeding mass adoption. Whatever these issues are need to be identified and rectified to the extent they can. I truly hope it's not the obvious answer - "It doesn't provide anything most people want or need".
