Recently, someone asked me again, "Do retail investors need to understand blockchain builders and bundle transactions?" I think understanding enough to "not think you're competing with the entire network of miners" is about right... Basically, the transaction you broadcast may not be queued in the order you expect; some will be bundled, and some will be smuggled through together. You don't need to study it to the level of academic papers, but at least know: public mempool = easy to be front-run or inserted; key operations (large swaps, liquidation margins, NFT dumps) shouldn't be stuck on low fees—better to do fewer transactions than be used as an ATM. Also, don't be too superstitious about the labels on on-chain data tools; I also agree with recent complaints that they are "lagging or misleading." It's better to look at transaction paths and actual behavior than just the labels. My roommate saw me studying the order of bundling for a long time and said I looked like I was fighting for a seat on the rush-hour subway... I thought about it, and maybe he's right.
