I guess moving on forward, like the LST platform you mentioned, solana will try to mimic the success of ETH in attracting big TVL through LST and L2. I've seen solana also having L2 in development, some other staking project like solayer also exists beside the one you mentioned, I guess it's a good thing, unlike TON that just stuck in reminiscing the glory of NOT, solana actually doing something to keep TVL high.
Solana has its own L2 network? That's new to me. I'd say this is highly unecessary, considering that the main Solana blockchain has ample transaction capacity. It's 10x better than Ethereum. An L2 will definitely bring more people into Solana. It might as well add more fuel to the hype.
Let me tell you that the next big thing is not SUI, but rather Aptos. It's highly-scalable, uses an innovative programming language for smart contracts (Move), and it's funded by VCs. The project has an "horizontal approach" to scaling. Imagine what will happen if it "blows up". Market prices will certainly go all the way to Mars.
Solana might see better days if it manages to achieve stability over time. The newly-launched "Firedancer" node software aims to solve this once and for all. It's written in C, unlike the official Solana node software written in Rust. The latter has high performance, but prone to issues. C, on the other hand, is much more stable. It's likely Solana will become as good as Ethereum if the new node software becomes a success. Developers need to work hard if they want their project to stand the test of time. Maybe Solana will reach a new ATH? Only time will tell.
