I just woke up and saw a retail trader asking, “What exactly do block builders do?” …Honestly, I think retail traders don’t need to know how they order transactions or how they assemble bundles, but at least they should know one thing: a bundle is basically an “express lane ticket.” Big players pay for priority, package everything into a single block, and submit it—other people can’t see what’s inside.

This is easy to spot on-chain. If you see a transaction with two nearly simultaneous MEV calls sandwiched before and after it, that’s basically it.

Retail traders don’t need to know how to write this, but at least they need to know how to read it; otherwise you’ll never know who you’re competing with for gas.

I also happened to see, in the past few days, a new L1 starting to roll out incentives to attract TVL. Long-time users are already saying, “mine, then sell.” In reality, big players got the optimal path long ago through bundles, and retail traders can only follow and grab whatever’s left. In plain terms, knowing this can at least help you pay less tuition.
