Recently, people keep asking me: why does on-chain data always seem to “pause” for a moment, even though the blocks are being produced properly? To put it simply, what you see isn’t the chain itself, but a series of intermediaries: the indexer is scanning logs and building a database, the Subgraph also needs to synchronize before you can query it, and RPC might be rate-limited or queued. Any hiccup in any of these links makes you feel like the “chain has stopped,” but in reality, it’s just your data pipeline that’s clogged.

Now, with modularization and the DA layer narrative making developers excited like it’s New Year, users are confused: I click a button, and I still need to understand where the data is going? Anyway, whenever I see latency, I first suspect: is RPC overwhelmed? Is the indexer lagging behind? Don’t jump to the black swan explanation right away… although I’m also quite afraid of real black swans. That’s all for now, I’m off to work.
