I just came across an article about block builders and bundles. Honestly, retail investors don’t need to study it too deeply. Knowing the gist is enough—basically, someone can decide the transaction order, bundle them into a block, and you know the rest: front-running, sandwiching, and all those shady moves mostly rely on this. But researching too specifically is pointless, because you don’t have the ability to build bundles yourself, the cost is too high, and the risk isn’t small either. If you get targeted, it’ll just be a hassle.

Anyway, I think it’s enough to know that this exists. In normal times, be a bit more alert when watching on-chain data, and don’t be an idiot who rushes in as the first one—especially those contracts that snatch the public sale. But now there are more AI Agents; automated trading and on-chain interactions are becoming more frequent. Some people hype it to the sky, but in the end, it still comes down to security. You can tell at a glance who’s just stacking narratives and who’s truly tightening security.

That’s my take. For this kind of overly technical stuff, I’m keeping a “know it but don’t get involved” mindset. Pay tuition occasionally—once you learn the lesson, you’re good.
