Lately, people keep asking about block builders and bundles—how much do retail investors really need to understand? I think knowing just this is enough: “Your transaction may not go straight into a block; it could be bundled and reordered.” Don’t force yourself to dig in so deep that you could work as a builder. Just remember two things: first, don’t randomly click signatures from unknown sources; second, for large or urgent transactions, use reliable wallets and RPCs as much as possible. If needed, split the transactions into batches and add a bit of fault tolerance—don’t give other people a chance to sandwich you or insert themselves into your order. Modularization and the DA layer have been getting a lot of hype lately, and developers are genuinely excited, but from the user side, it’s basically this: just don’t make me stuck waiting for transfers for half a day or have the fees drifting around… I’m more like the “slowly watering succulents” crowd, not the kind that pulls them out every day just to check whether the roots have grown. That’s it for now—don’t be careless.
