I stared at that newly launched indexer all night—my eyes were aching so badly they kept streaming tears, and my neck got stiff too. Later I found that for the same block, the timestamp between my own node and Alchemy was off by four seconds—four seconds! In MEV, that’s enough to get you killed twice.

To put it plainly, “on-chain data” isn’t really on-chain; someone processes it for you first, then spits it back out. You think it’s real-time, but actually that RPC node might be in Seattle, and the indexing service adds yet another layer—so by the time it reaches you, it’s already secondhand news. Lately there’s been all that noise about NFT royalties—creators cursing the platforms for taking a cut, and platforms saying liquidity matters most—but have you ever thought about this: once a royalty event is recorded on-chain, the time gaps across all those different front-end displays could mean even “first-time” decisions are built on fake real-time.

Anyway, I’ve developed a weird habit now: before any important transaction, I check two different sources, even if it’s a hassle. If my stomach feels “tight,” then so be it. Better that than getting tricked by fake on-chain data. That’s it for now—I’m going to put in some eye drops.
