I've been recently studying words like "block builder/builder" and "bundle." The more I look, the more I think retail investors really don't need to learn engineering... For someone like me with a small position, knowing that "my trade might be bundled, front-run, or sandwich attacked" is enough, and just remember a few small things: try to use routing with anti-sandwich features / set tight slippage limits, don't trade in pools with very low liquidity, and don't give out permissions randomly. As for how exactly builders bid, who collaborates with whom, honestly, even if I understand it, I can't really change anything, and it might just scare me into not clicking confirm. By the way, I've also been observing the recent disputes over privacy coins / mixing compliance... I feel like these underlying issues of bundling and "who can see you" will eventually come back to ordinary people. First, get your trading habits right, that's all for now.
