Recently, I came across a bunch of posts that interpret ETF capital flows, U.S. stock market risk appetite, and crypto price movements all together, which made me a bit tired... Anyway, I’m now trying to focus on just one main thread: what does this chain / this layer 2 ultimately "rely on"? Data availability essentially means whether you can replay the ledger afterward; ordering is whether who comes first or second can be arbitrarily interrupted by a few people; finality is whether what you think is settled will flip again. The terms sound intimidating, but asking these three questions can basically filter out half of the noise. After lowering my expectations, I feel more relaxed: I don’t expect to hit the rhythm every time, just see if the design is self-consistent, and leave the rest to time.
