Lately, I've been hearing people talk about "modular chains" a lot, and I've been pondering for a while: for us end users, honestly, there are probably only two main things—cheaper and less likely to get stuck. In the past, when congestion happened, transactions would slip, and confirming a transaction felt like opening a blind box; now, by separating execution, data, and consensus, theoretically, whoever causes the congestion takes the blame, and the experience can be more stable (at least from what I've seen, the latency distribution isn't as crazy).

But don't get too romantic about it either; in your wallet, it still looks like just a few buttons: sign, wait, sign again... The main difference is more about how the routing is handled behind the scenes and how the costs are shared. Recently, with testnet incentives and point expectations, everyone has started to wonder, "Will the mainnet issue tokens?" I'm actually more concerned about: don't mess up the chain with congestion just to farm points, ending up paying the bill ourselves in the end. Anyway, I'll just use the simplest method—run a few more transactions, record the slippage, and feel more at ease.
