In theory a L2 network coukd solve the scaling problem, but every time I've looked at L2 solutions theve had terrible UX.
I thought it was interesting that BSV seemed to scale just fine, and you could also store entire files on it, including JSON, HTML or even music or videos.
This seemed like an amazing innovation to me, made even more amazing by the fact that it was, by all accounts, the original protocol.
You could do some pretty amazing stuff with it, for example store a SPA on chain and then store individual posts on chain, and have the SPA read the app.
Unfortunately, the ecosystem was completely greed focused, and nobody is interested in technological advancement in the slightest.
L2 networks achieve scale by... Not being blockchain. And by not offering the double-spend protection guarantees of blockchains.
So this statement is "you can scale blockchain tech by using another tech in its place that doesn't offer the same guarantees".
